From that year till the eve of VJ  day, this American Air unit had undergone great changes in terms of  organization, subordination, even name. But one thing remained  unchanged and that was they fought against the Japanese under the  command of Chennault and they had made contributions to the victory of  the Chinese War of Resistance Against Japan. However, for a long time,  Chinese historians did not give due attention to or make objective  assessment of this issue in Sino-US military relations. One reason for  this is that in the past, historians' attitudes toward this issue were  affected by the assessment of Chennault's personal political position,  that is, Chennault himself was always adamant in his support of Chiang  Kai-shek and opposition to the Communists. Another reason is that, the  positive contributions made by Chennault and the American airmen in  China during the Chinese War of Resistance Against Japan were often  overlooked by historians in articles commenting on the Stilwell  Incident because they were easily preoccupied by some of Chennault's  inappropriate strategies such as the view that a considerable air  force would be able to bring Japan to her knee. Therefore, this essay  will probe into the close relationship between American Air Force in  China and Chinese War of Resistance Against Japan from another point  of view. We sincerely invite criticism from other historians.$ #T4I. From American Volunteers in Chinese Air Force$ to American Air Task Force in China$ (August, 1941 -- March, 1943)#t #M1American Air Force in China and Chinese War of Resistance Against  Japan#m #M2American Studies in China#m By the summer of 1941, Japanese invaders had already occupied more  than half of Chinese territory while the United States, on the other  shore of the Pacific, had not yet declared war on Japan. However, on  August, 1. the Chinese Government in Chongqing made formal  announcement in a Communique that the American Volunteers, composed of  American pilots, had been established and become a unit of Chinese  Armed Forces.#+[1] This marked the beginning of American participation  in China's war against Japan. But how did American Volunteers in  Chinese Air Force come into being?$ On the Chinese side, since the "September 18th Incident", the  Kuomintang Government, due to the ever-growing strength of Japanese  Air Force, realized the importance of strengthening the Air Force and  took many measures and efforts to catch up within a certain period of  time. However, air force development did not achieve much. Because old  China had a poor foundation for industry and lacked financial  resources and technology.#+[2] And the embezzlement and corruption of  government officials made it more difficult to develop Air Force Šwithin a short period of time. Chinese Air Force development, thus,  had to depend wholly on foreign countries while China itself could  only produce parachutes.#+[3] After the "July 7th Incident", under the  attack of powerful Japanese Air Force, the pitiably small Chinese Air  Force was further weakened. At the end of 1940, the number of combat  aircraft was reduced from 314 before the "July 7th Incident" to 65.  Wang Shijie, the Minister of Foreign Affairs in the Kuomintang  Government held that the Air Force had completely lost its fighting  power.#+[4]$ On the contrary, in order to thwart the Chinese resistance materially  and psychologically, Japanese Air Force, starting from May, 1939,  intensified its air offensive and frequently bombarded the southwest  areas which had not been occupied by Japan with squadrons ranging from  10 planes to more than 100 planes for 2 or 3 years running. Since  China had already lost its air domination, except for a few  antiaircraft guns, few large squadrons of fighters took off to  intercept enemy planes. In July, 1941, the reckless Japanese planes  even dared to land on Taipingci Airport in Chengdu and grabbed the KMT  flag when they raided Chengdu.#+[5] Therefore the period from the  second half of 1940 to the first half of 1941 was called the "Darker  Era" in China Air Force history.#+[6] Facing the ever-growing air  crisis, the KMT Government had to take measures to ease the situation.  At that time, the only feasible way was to seek international aid yet  such aid was very difficult to obtain. The Soviet Air Force  Volunteers, who had rendered strong support to China, had returned  home due to changes in European situation. Requests put forward to  Britain had been politely rejected. Thus the KMT Government went all  out to secure aid from the United States.$ As early as January, 1940, the KMT Government had expressed the hope  that the United States could assign some pilots as coaches at  Kuomintang Aviation School. But the American Government was very cool  to the request because it wanted to maintain neutrality, despite the  sympathetic public opinion at that time. In June, 1940, when the  Chinese side intended to invite an officer in American Air Force to  act as the general coach at the Air Force Staff School, American War  Department did not give him the permission. Afterwards, in addition to  seek help through normal diplomatic communications, the KMT government  also tried private channels. On October, 18, Chiang Kai-shek met  Nelson Trusler Johnson, American Ambassador to China, and explicitly  raised the question of aid in planes. Chiang argued that American Air  Force Aid was necessary because it could boost Chinese  people's determination in fighting the Japanese, raise the morale of  the soldiers and, threaten the flanks of Japanese Force.#+[7]$ The American Government began, therefore, to consider the following  requests put forward by the Chinese: to obtain 500 to 1000 aircrafts  from the United States within one year and American Volunteers coming  to China to help fight against the Japanese. Through heated argument,  in order to gain time to arm themselves and also to prevent the  Japanese from expanding to the south at least before April, 1942,#+[8]  the American Government decided to take out, for the time being,  100 P-40 aircrafts from the supply to Britain and to transfer to China  these planes. In terms of Volunteers, President Roosevelt decided to  offer support in spite of the strong opposition from the military  circles. On Dec. 15, 1940, President Roosevelt permitted in an Act  American pilots to leave American Air Force and go to fight in China Šand he also commanded the State, Army, Navy and Finance Departments to work out  detailed plans for the above proposal.$ Obviously, the establishment of American Volunteers in China's Air Force  was a product of Chinese consciousness of the air crisis and US  analysis of Far East situation. After fairly sufficient preparation,  on August, 1, 1941, the American Volunteers were formally set up and  Chennault was appointed Colonel commander-in-chief. Chennault, a  Texas-born ex-Captain of an air unit in the Army, had been the adviser  of Chinese air defense since 1937 and had devoted himself to China's air  defence and air force development. In spite of these, the Volunteers  at that time was far from being satisfactory either in staff or in  equipment. The Volunteers only had three fighter squadrons with 112  airmen most of whom had never flown a fighter nor did they have any  experience in fighting against the Japanese Air Force. Some members  had to be relieved because they could not meet the requirements even  after the training. The cambat planes used by the Volunteers were  outdated Curtis P-40 aircrafts. Although this kind of fighter had  advantages in rectilinear flight and diving speed and better-equipped  armor to protect pilots, it was overshadowed by the Japanese major  combat fighters--Zero-type fighters in terms of #^climbing#^^ speed and  flexibility.#+[9] What's worse, at first, the P-40 fighters of the  Volunteers had no sighting device, bomb racks, auxiliary tanks and  lacked stocked spare parts. Therefore, quite a number of military  experts thought the Volunteers would last no more than 3 weeks in the  battles.#+[10] Even Chennault himself never expected to achieve much  by their efforts.#+[11] According to the current situation, the first  thing Chennault did was to borrow British airports in Burma as the  training sites for the Volunteers. He worked out new tactics which  suited the Volunteers based on the summary of his observations of  fighting with Japanese aircraft since he came to China. That is the  coordination of two fighters and "Hit-and-Run" guerilla tactics.$ When the Volunteers were founded, the situation in the Far East became  more tense. In late July, 1941. Japan and French Viche regime reached  an agreement, by which the Japanese secured the right to use 8  airports and one navy base in Vietnam. In November, Japan allocated  245 fighters to the south of Vietnam and intended to invade and attack  Yunnan Province. Thus, Chiang Kai-shek asked British Air Force in  Singapore for help, and in the mean time, required the American  Volunteers to come back to defend Kunming. Just at that moment, the  Pacific War broke out and the Japanese forces in Burma were ready to  attack. The British forces asked the American Volunteers to  defend Rangoon. As a result, this small-size air force unit was  divided into two sub-groups. Two fighter squadrons flew to defend  Kunming while the other one stationed in Rangoon.$ Since June, 1940 (except Sundays), Kunming was almost daily bombarded  by the Japanese at 10 o'clock in the morning. Since China was in no  position to fight an air war, Japanese bombers never needed fighters  to escort them. However, it was no longer the case when the American  Volunteers came to Kunming on December, 19. On December 20, ten  Japanese bombers attacked Kunming as usual. The American Volunteers  took off to intercept. The battle ended in the total destruction of  the Japanese bombers and Kunming was unscathed.#+[12]$ The first victory of the Volunteers greatly inspired the Kunming  citizens, who suffered a lot from air raids. "The good news spread  quickly and everybody was delighted and excited." Five days later, the ŠJapanese airplanes suffered another severe whipping. Since then, for  about one year, the Japanese could not raid Kunming.$ The third fighter squadron of the Volunteers in Burma was led by David  Olson. Strategically it was under the command of the British but  tactically it was directed by Chennault. It was comparatively weaker  in strength, and did not have as complete air defence information  network as the other two fighter squadrons in Kunming. Even under such  unfavorable situation, this squadron destroyed 7 and damaged 2  Japanese planes in their first encounter with Japanese air force on  December 23. American pilots fought courageously during the battle. As  the Japanese later reinforced their attacks in Burma, this squadron  lost many aircraft. As a result Chennault sent another 17 P-40  fighters to assist the third squadron. By the end of the Battle of  Rangoon in March, 1942, this squadron had participated in 31 air  combats and destroyed 217 Japanese fighters with another 43 listed as  being possibly destroyed. Their sacrifice for this achievement was 4  pilots and 14 P-40 fighters. Although, Rangoon fell later, their  contributions were indelible. King George VI of Britain awarded the  American Volunteers fighting in Rangoon the Medal of Cross, the  highest honor in Britain.#+[14]$ After the fall of Rangoon, the third squadron also moved to Kunming  for a short rest and reorganization. And they joined the Chinese Air  Force to launch a series of sudden attacks on Burma. But these attacks  were small in scale and did not draw much attention of the  Japanese.#+[15] In May, 1942, north Burma fell into enemy hands,  so the American Volunteers shouldered the responsibility of preventing  the Japanese troops from crossing the Nu River and attacking Yunnan.  On May, 2, Japan's 56 Division captured Nankan on the Chinese Burmese  border. On May, 5, the Japanese main forces advanced to areas along  the Nu River. They had to stop advancing due to the destruction of  Huitong Bridge over the river. Since the situation was tense, Chiang  Kai-shek, through Madame Song Meiling, asked the Volunteers to go all  out to attack the trucks and ships in the area between the Nu River  and Longling. The American Volunteers at this time had already had the  ability to shoulder the task of bombing the enemy after a period of  rest and reorganization. The improved P-40 E-type fighters which had  recently been transferred from Africa also enabled the Volunteers to  throw bombs at the enemies. Since May, 7, under the command of  Chennault, the Volunteers overcame difficulties before the monsoon  and conducted bombing for five days running of the Japanese advance  troops, the warehouse of military goods and materials and vital  transportation lines, etc. As a result, with the long supply line of  the Japanese and the coming of monsoon, the Japanese forces failed to  cross the Nu River and thus it helped ease the tension in Kunming. At  the same time, the Japanese Air Force assigned two squadrons No.50 and  No.8 to Laxu Airport to attack Kunming, Yunnan Railway Station and  Dali, with the intention of assisting its ground forces. But they had  to admit that "since the fearless counterattack and tactics of the  enemies, our side also suffered great losses."#+[16]$ With the coming of the monsoon, the combat in Burma came to an end. Up  to then, along the China-Burma-Vietnam line, the American Volunteers  had involved in more than 100 air battles and destroyed 260 enemy  planes. After they succeeded in blocking the Japanese from crossing  the Nu River, the American Volunteers moved their main force to  Chongqing, Hengyang, Guilin, Lingling and other bases. When a squadron Šof the Volunteers first flew to Chongqing, citizens there, who had  long suffered from the Japanese air raids, were extremely excited.  "Large crowds could be found on verandas, in the courtyards and  streets. People are cheering and cheering, waving their hats, clothes,  flags and some raising their babies over their heads to show their  happiness. Their joyous shouts shook the city and could be heard  everywhere in the city. It was the first time for them to see planes  on their side."#+[17]$ While the American Volunteers were fighting in south and central  China, the force itself underwent an enormous readjustment since its  foundation. On the one hand, quite a number of the staff departed due  to the expiration of the contract. On the other hand, the United  States had long before declared war on Japan, so it was not necessary  for the Volunteers to keep its form and title. In addition, the  Chinese Government together with the press both in the U.S. and China  demanded and advocated the strengthening of U.S. Air Force aid to  China. The United States, with the approval of the Chinese Government,  disbanded the Volunteers on June, 27 and the decision became effective  on July, 4. The reorganized Volunteers and the newly arrived Air Force  officers formed the United States Air Task Force in China, under the  command of Chennault, who was then Brigadier General. The task force was  somewhat more powerful than the former Volunteers since it now had  under it the 23rd Fighter Group, the 16th Fighter Squadron and the 16th Bomber  Squadron.$ Although the United States Volunteer had disbanded, the contributions  they had made to the War of Resistance Against Japan were indelible.  This was not only shown in their outstanding achievement of defeating  a large and strong enemy with smaller and weaker force and destroyed  300 enemy planes within 11 months, but also shown in the fact that  their participation enabled the Chinese Air Force to go through a dark  era, and greatly inspired the Chinese people. The Communists Party  praised the Volunteers "for displaying the courage and determination of  the American air force to fight against the Japanese and their  excellent skill."#+[18] The KMT Government awarded the Volunteers with  medals for their bravery and great achievement.$ The Air Task Force in China, after reorganization, was a formal unit of  regular force, much stronger in equipment and staff. The core of the  force was still those former Volunteers. However, since many veteran  Volunteers had departed, the combat effectiveness was weakened for a  period of time. Under this circumstance, the Task Force started  fighting against Japan in southeast China. From the very beginning,  American fighters taking off form Hengyang base subjected Japanese  airports, warehouse, ships and military camps in Wuhan, Guangzhou,  Nanchang and Jiujiang to constant bombing. On July, 19, American  fighters even attacked the Headquarters of Japanese Ground Forces in  Linchuan. They also provided air protection for Chinese forces who  were fighting bitterly with the Japanese in the Linchuan Battle, which  changed the situation that the Chinese forces always had to fight  without air cover.$ All these constituted a great threat to the Japanese in the occupied  area in Central China so Japan decided to eliminate the Air Task Force  before it could get a firm foothold in the area. Since July 30, 118  planes operated by experienced Japanese pilots succeeded in breaking  through Hengyang air defence network and took turns to bomb Hengyang  for 36 hours. The Task Force fought fiercely with the Japanese. As a Šresult, the Japanese not only failed in destroying the Hengyang base,  but lost 17 fighters and bombers.#+[20] In the following month, the  Task Force extended their front line to Burma and Vietnam. On August  12, bomber squadron first attacked Haifang, an area outside China,  which was occupied by the Japanese. Later, the other Japanese military  bases, arsenals, oil depots in Burma and Vietnam were frequently  bombed. According to the statistics of July and August, the Air Task  Force had attacked the occupied areas in China, military installations  and military positions in Vietnam and Burma for 23 times. The Japanese  lost 28 planes in the battles and 30 planes were destroyed on the  ground, while the Air Task Force only lost five planes and four  pilots.#+[21] By the end of October, the American task force also made  a raid on north China and bombarded a coal mine of Kailuan Company in  the east of Hebei Province. It was regarded as the "first air raid in  North China". They also attacked Hongkong, Kowloon. On November, 25,  the American planes made their first night attack on Hankou, where the  Japanese military installations and gunboats suffered damage. Although  these operations still fell under the "Hit-and-Run" guerrilla tactics  they revealed the tenacious spirit of the American Task Force and they  also showed that the Japanese Air Force could no longer have the air  control totally in its own hands as before.$ Although the Air Task Force had challenged the air control of Japan,  it still had a lot of difficulties to overcome before it could  completely seize the air control. This was not only due to the fact  that Japan had advantages in terms of the number of planes and  training, supplies, equipment and transportation,#+[22] but also due  to the fact that the Air Task Force had a great shortcoming: once  their planes were damaged, it took a long time for them to recover and  other supplies were also lacking because of the limited capacity of  the Hump transportation. Therefore, in the second half of 1942, both  American and Chinese press strongly demanded that American Air Force  in China be reinforced. One American newspaper stated that "in order  to make it possible to take over hard work, necessary supplies must be  provided as soon as possible."#+[23] General Chennault had a clearer  picture of the situation and proposed several times to the American  Government for further reinforcement. On October, 8, 1942, Chennault,  in his letter to Wendell Willkie, special envoy of the President, made  an assessment on the war situation. He asked the American Government  to provide 105 new model fighters, 30 medium-size bombers, and 12  heavy bombers in the following months. He held that it is essential to  keep an air force of this size. But loss was inevitable during the  war, therefore, he asked that 30% of fighters and 20% bombers should  be replenished.#+[24] In order to persuade the President, Chennault  emphasized that if his plan could be successfully carried out, it  could not only be beneficial to the development of General MacArthur and the  Navy in the Pacific Ocean, but also could make the Chinese permanent  friends of the United States. Besides, Japan could be driven out of  China within half a year.#+[25] Since Chennault's proposal was  supported by Harry Hopkins, Lauchlin Currie, advisers to President  Roosevelt, and Chiang Kai-shek was also actively lobbying, Roosevelt  turned to be positive on this issue.$ #T4II. From the founding of the 14th Air Force of the U.S.$ to the end of the air war over Chinese Territorial$ Space (March, 1943--March, 1945)#t At the Conference of Casablanca held in January, 1943, President ŠRoosevelt emphasized the political influence of the expansion of U.S.  Air Force stationed in China, pointing out that regular bombing of the  Japanese would "greatly encourage the Chinese people". In his telegram to  Chiang Kai-Shek after the conference, President Roosevelt promised to  immediately reinforce Chennault.#+[26] On March, 8, Roosevelt made his  final decision on America's major military plan in China in 1943: the  establishment of the 14th Air Force, the gradual increase of its  strength to 500 fighters; if conditions of equipment permitted, the  increase of the amount of China-India air lift to 10,000 tons a month.  On the 11th, the Task Force of American Air Force in China was  reorganized into the 14th Air Force. Chennault was designated Major  General Commander of the force. The 14th Air Force was independent of  the 10th Air Force, whose main tasks were to protect its own  transportation line over the Hump; to search out and destroy Japanese  planes and military camps; to bomb Japan's military installations in  China; to bomb Japanese ships along Chinese coast and nearby islands;  to destroy enemy's supplies and military installations in Indo-China,  Burma, Thailand and Taiwan; to encourage China's Anti-Japanese war and  to use all means possible to support ground forces.#+[27]$ However, though the 14th Air Force got support from President  Roosevelt, it did not mean that Chennault could carry out his military  plan smoothly. On the contrary, since the Yunnan-Burma road was not  yet open, the provisions of the 14th Air Force could only rely on the  air lift over the Hump. Though the transport division of American Air  Force had made great efforts, the goods and materials available were  limited. In addition, the 14th Air Force was still under the authority  of Stilwell, who was in charge of material distribution, so it did not  receive any priority in distribution of material. What's worse, since  the monsoon came ahead of time, the transport line over the Hump was  almost completely cut off in April, 1943. During the first 10 days in  April, the 14th Air Force received only 45 tons of supplies, instead  of 245 tons as planned. The Air Force had to stop its operation  temporarily. In fact, there was only one sortie in April, that is, on  the 24th, nine B-25 Bombers attacked a Japanese Base in Burma.$ By taking advantage of the situation of American Air Force in China,  Japan strengthened its air attack. At the end of March, No.3 Flight  Regiment of Japanese Air Force first attacked Guilin from Guangzhou.  At the beginning of April, American front bases in Hengyang, Lingling  and Jianou were also attacked. Since March 30, the Japanese made up  to 80 sorties on Lishui Airport for three days in succession; on  April 22, the Japanese attacked Lingling with a fleet of 44 planes.  They attacked Yimei airport in Yunnan on the same day, destroying 17  American planes. On April 29, 31 Japanese fighters attacked Guilin  again, forcing American Air Force to retreat.$ This situation forced the Chinese government to suggest that Roosevelt  call Stilwell and Chennault back to Washington for consultation. At  the end of April, Chennault submitted to Roosevelt his military plan  for the second half of 1943 when he got back to the US. The main  contents were: the 14th Air Force planned to gain air control over  China within two months since July. Then it would carry out offensive  in three stages to destroy Japanese transportation line and Japanese  homeland, to destroy Japanese ships up to 600,000 tonnage in 6 months.  As far as supplies were concerned, from July to September, 4700 tons  were needed for each month. From September on, 7100 tons were needed  for each month.#+[28] Taking the above-mentioned plan into Šconsideration, especially the plight of the 14th Air Force, Roosevelt  decided to take measures to meet Chennault's demand. At the Trident  Conference in Washington in May, Roosevelt expressly held that every  month, out of the 7000 tons of materials air lifted over the Hump  4,700 tons should go to American Air Force in China. In order to  increase the airlift capacity over the Hump, Roosevelt  assigned another officer to take charge of the air lift after the  meeting. As a result, the airlift tonnage increased from 3,000 tons in  May to 5,500 tons in July.$ Due to these measures, the supplies of the 14th Air Force were  improved to some extent. It became active again in the air. On May 4,  six B-24 bombers flew to attack Hanoi, Vietnam. They also bombed  Sanya, a city on the southern end of Hainan Island occupied by the  Japanese. During the bombing of Hanoi, 75% of the bombs hit the  targets. Therefore this action was proclaimed by Henry Lewis Stimson,  Secretary of War, as "the most significant and the most destructive  air raid of the allied air force taking off from Chinese base."#+[29]  From May 6, the main part of American Air Force began to shift to  Guilin. On the morning of the 8th, 56 planes had been transferred. On  the same day 7 American planes air-raided the Tianhe and Baiyun  airports of the Japanese air force in Guangzhou, destroying 20  Japanese planes.$ The bombing offensive of American air force in China soon aroused the  great concern of Japanese Military Headquarters. It warned the  Japanese Air Force of American bombers moving into Guilin. It asked  the reinforcement of air outposts in North Kyushu, Taiwan and occupied  territories in China. Meanwhile, it instructed the Japanese southern  army to cooperate in the air battle in China.#+[30]$ At the same time, to increase the capacity of transportation on the  Yangtze River and to eliminate Chinese army on the right bank of the  Yangtze River from Dongting Lake to Yichang, Japanese No.11 Army began  its "elimination battle on the Yangtze River" from early May to mid- June. Thus, in addition to the air battles over Yunnan, the 14th Air  Force also shouldered the task of air support for Chinese army in  Hubei Province. Chennault said, "during that time, it was common for a  pilot to strafe along the Yangtze River one day, and 48 hours later  attacked Japanese bombers in Yunnan."#+[31] During the first ten days  in June, the 14th Air Force continued to bomb in turn Yichang, Puxin,  Bailuoji and other places in west Hubei in large formation, which  damaged the miliary center and facilities of the enemy, and gave  effective cover to the Chinese ground forces. As a result, Japanese  army was defeated. Chinese and American forces gained a full victory  in west Hubei. Both Chinese and American sides highly praised the air  support from the 14th Air Force. An American Major remarked that  "Chennault's Air Force, though small, was such a great help to the  Chinese Army that I could not find another better example." Xinhua  Daily also commented in one short editorial that, "this victory was  achieved with the help of the Air Force."#+[32]$ Chennault began to think that the "Guerrilla Era" for American plane  was over. He decided to move his force from the rear to the advance  bases in the east as the first stage of his plan. From the 19th of  June, except for a fighter squadron and No. 308 Bomber Group still  stationing in Kunming, other squadrons flew to Guilin, Lingling and  Hengyang, so that the American Air Force in these three bases reached  considerable strength. The Japanese side was sensitive to the eastward Šmovement of American planes. Not only the invasion army in China  desperately needed to strengthen the air force. the Headquarters also  seriously felt that it was urgent to reinforce Japanese Air Force in  China to neutralize American air force. Therefore, on the one hand,  the Headquarters asked the southern army and its air force to assist  in bombing American bases in southwest China, on the other hand on  June, 7, it moved one fighter squadron from the Guangdong Army and two  heavy bomber squadrons from the southern Army and put them under the  Japanese Army in China.#+[33] By mid-July the air force of the  invasion army in China reached three fighter groups, two light bomber  groups and two heavy bomber groups.$ On July, 7, the 14th Air Force began to bomb Guangzhou; on the 8th,  they attacked Haifang; on the 9th, No.308 bomber group made a number  of sorties against Japanese ships in the Tonkin Bay, thus  ushering in the summer battle of 1943. In reaction to the American  offensive the Japanese air force launched a large scale counterattack  starting from July 23 in order to protect its transportation line.  More than 150 fighters and bombers took off from Wuhan and Guangzhou  bases on that day and bombed Hengyang, Lingling and Guilin airports,  which marked the beginning of the 9-day battle for the air control in  south China. On the first day, Japanese forces lost 8 fighters, 6  bombers. For the following 8 days, they lost altogether 62 aircraft  while the Americans only lost 8 aircraft and 3 pilots.#+[34]$ When the air war turned violent, the 14th Air Force once again had the  support of Roosevelt. On August, 7, soon after George E. Stratemeyer,  the newly appointed air chief of the army in the India-Burma Theater,  arrived in India, he sent reinforcement to American air force in  China, thus increasing Chennault's power. Japanese air force, after  three weeks of rest and reorganization launched another counterattack  in mid-August. Bur even the Japanese acknowledged that, "nowadays  American Air Force in China are competent, and the pilots are better  qualified than those fighting in the south".#+[35] Therefore at the  end of August, the Japanese could not manage to neutralize the summer  offensive of the Americans. In September and October, the 14th Air  Force extended its range of activities to the whole of central and  south China. The force also assisted the Chinese army fighting in  north Yunnan and west Burma by bombing Japanese military installations  and camps. Since the Japanese were losing their air  control in China, their way and scale of fighting also changed. In  order to avoid interception of American planes, the Japanese air raids  on South China were seldom conducted in daytime, and most of them had  the characteristic of uncertain whereabouts and were small in size.$ The American Air Force in China were not satisfied with these  achievements. They were actively preparing for new offensive. On  November 4, "Chinese-American Air Force Composite Division", on the  suggestion of Chennault, was established and moved into their  respective airports. According to the American Intelligence officer in  the division, with the latest P-40 fighters and B-25 Bombers, the  Division was an unmatched offensive Air Force.#+[36] At that time the  Japanese army were mustering 100,000 ground Forces and 250 aircraft to  attack the 6th War zone, initiating the Battle of Changde. The newly- setup composite division joined the 14th Air Force in the bombing of  the Japanese in Changde, Huarong with more than 200 planes since  November. According to Bai Chongxi, from November 10 to December 16,  280 sorties of bombers and 1476 sorties of fighters were made bringing Šdown 25 enemy planes and destroying 12 planes on the ground, and  sinking a great number of ships and bringing losses to the  army.#+[37]$ Besides, the 14th Air Force Chinese-American Composite Division  achieved considerable results in attacking Japanese ships along  southeast coast. In November, another important action of the two  groups was the air raid on Xinzhu airport in Taiwan. The Xinhua Daily  regarded it as "a historical sudden attack on Thanksgiving Day". On  the 25th, under the leadership of Colonel Tex Hill, Sino-US Air Force  raided Xinzhu airport which was only 660 miles from Japan, destroying  more than 40 Japanese planes. This was not only the best record of the  American air force in the Far East, but also the first bombing by  allied forces of Taiwan since the U.S. entered the war. Therefore it  greatly shocked the Japanese Headquarters and was the immediate cause  of the Yu-Xiang-Gui Battle launched by the Japanese Army in the spring  of 1944 with the direct purpose of destroying American bases on  Chinese mainland.$ When time moved into 1944, the 14th Air Force was further strengthened  with 254 fighters and bombers and material supplies which used to be  Chennault's headache, were improved. In the last few months in 1943,  the air lift tonnage over the Hump gradually increased. Since the  Transportation Division was better equipped with advanced  communication and navigation facilities and renovated B24DS aircraft,  it succeeded in making their slogan of "airlifting 10,000 tons by  Christmas" a reality.#+[38]$ As early as in October 1943, Chennault worked out a plan for 1944,  which divided China into two battle theaters along the 108 east  longitude. The actions in the first half of the year were mainly on  the west battle theater due to the weather, supporting battles in  Burma, safeguarding the airlift over the Hump; in the second half of  the year, they would conduct air battles in east China, aiming at  destroying Japanese Air Force and transportation capacity. In order to  realize the plan, Chennault demanded that the supplies in the first  half of the year be increased from 1,900 tons in January to 6200 tons  in June in east battle field, whereas in the west battle field, the  supplies be decreased from 6900 tons, in January to 2700 tons. Since  he was especially concerned with the actions in the east, Chennault  also demanded that 20,000 tons of materials should be stockpiled  before July in the east theatre. As far as combat planes were  concerned, Chennault#O &hoped by autumn he could have 6 fighter  squadrons, 2 medium-size bomber groups and 3 heavy bomber  groups.#+[39] However, since the American air force planners in the  army had already proposed to air raid Japan proper by using long-range  bomber taking off from Chinese bases, Chennault's plan did not obtain  support. In addition, the supplies that Chennault demanded were so  immense that it was reasonable for General Stratemeyer to refuse him  from the position of rear-service. In fact, Chennault's plan was too  subjective itself. He did not pay enough attention to movements of the  Japanese Army. In spite of this, it was proved later that his demand  of stockpile of supplies in east battle theater was of strategic  wisdom.$ With the strengthening of American Air Force in China since the summer  of 1943, the Japanese Army realized that the past tactics of "joint  attack of fighters and bombers" did not work effectively. In addition, ŠAmerican Air Force's attack on Japanese transportation along Chinese  south-eastern coast and along the Yangtze River area had to be taken  into consideration. Since November Japanese began to try to work out a  plan which would completely solve the problem of air control in China.  At the beginning of November, Japanese General Chief of Staff Shanshan  first pointed out, "if it was difficult to neutralize American Air  Force in China, ... why can't we occupy the railway from Canton to  Wuhan so that the American Air Force could not use the bases in  southeastern China?"#+[40]_ On January 24, 1944, the proposal was  approved by the Emperor. Thus the last large scale action plan in  Chinese Territory -- No.1 Battle Plan was formulated. The main  objectives were tactically, to eliminate American Air Force in China;  strategically, to open Railway from Canton to Wuhan, so that all the  railways in China would be connected, which would help support the  Japanese army in southeast Asia through transportation of materials  and troops. For this purpose, Japanese army planned to use more than  10 infantry divisions and 2 Divisions from the 5th Air Force.$ At first the allied force knew nothing about this plan and the 14th  Air Force did not readjust their activity at the beginning of 1944.  However, the assembly and progress of Japanese army in the winding  place of the old Yellow River course and along the Yangtze River  gradually aroused the attention of the 14th Air Force. Chennault began  to warn Stilwell that the deployment of Japanese army in Henan  Province was the most dangerous action after the Pearl Harbor  Incident. He suggested that 5000 tons of materials be air-lifted to  China in May; a reserved air force be set up, etc. Meanwhile,  Chennault sent bombers to attack the ships on the Yangtze River and  the transportation line around Jiujiang and Yueyang. In March, the  purpose of the movement of Japanese army became obvious, so Chennault  began to make his battle plan and to carry out preparation work. He  first ordered four fighter squadrons and one medium bomber squadron  from Chinese-American composite Division to move into airports in  Liangshan, Enshi, Hanzhong, Ankang and other places in Sichuan- Shaanxi area, trying to destroy the iron bridge across the Yellow  River before the Japanese army crossed the river. However, the  Japanese army first ushered in the Henan Battle on April 17.  Ironically, on the same day, Stilwell demanded that the primary task  of the 14th Air Force was to protect the B-29 Bombers' Base in  Chengdu.$ In order to coordinate with the attack of the ground force, Japanese  air force assembled more than 90 planes in Xinxiang, Henan, and  Yuncheng, Zhangde to bomb the position of the Chinese army. On April  19 alone, the Japanese army flew more than 200 sorties, dive bombing  Chinese army for scores of times. The air control was completely held  by the Japanese. It was not until the 28th that the Chinese-American  Air Force began to bomb the iron bridge on the Yellow River. However, since the Japanese army had already set  up several substitute bridges, these bombardments could not prevent  the Japanese army from moving forward. On that very evening, the  Japanese army began to attack Xuchang.$ In May, American fighters began to be active in the battlefield, and  gained certain results. For example, on May 5, according to the report  from Stilwell's Headquarters, under the cover of American fighters,  bombers raided Xinyang marshaling yard and warehouses, the percentage  of hits reached 80%, which destroyed many lorries and military tanks. ŠThe number of casualties of the enemy reached 300 to 400.#+[41]$ On May 27 the Battle of Hunan broke out. The vanguard of the  Japanese army spearheaded towards Changsha and captured it on June 18.  At that time, the 14th Air Force encountered difficulties in every  aspect. In terms of combat planes, 350 planes were used to fight in  the Nu River and to defend the B-29 Base in Chengdu, so there were  only 150 planes available in the defence of the east line, out of  which only 90 planes could really be engaged in fighting. The  provisions for an all-round attack could only last 30 days. What is  more dramatic, Stilwell demanded to remove Chennault's commanding  power on the day that the Japanese army began to invade Hunan. Finally,  at that time, the weather in Hubei and Hunan was very bad. Despite  this, from the beginning of June, American planes still frequently  carried out offensives. Sometimes they flew as many as 50 sorties a  day to effectively attack enemy's airports, ships, troops and  installations. But all these could not stop the Japanese from advancing  south. After the fall of Changsha, the Japanese army continued to move  towards Hengyang. On June, 22, American Air Force had to abandon its  first front base in East China--Hengyang Airport.$ At the beginning of July, though the Japanese army progressed smoothly  on the ground, American force in the air seemed to increase greatly.  Since the weather became well, American airplanes increased sorties,  which brought great difficulties to Japanese rear service. According  to Shanshan's reminiscence after the war, the raid of the 14th Air  Force, in addition to the flood, caused damage to the railway south of  Hankou, which was difficult to repair. Before the defeat of Japanese  first attack on Hengyang, the Japanese army did not receive any  supplies. On July 2, only very limited supplies reached Japanese  front.#+[42]$ However, at this critical moment, American Air Force faced a severe  shortage of gasoline. During the first week in July, Chennault had to  order B-24 bombers to retreat to Kunming. By July 13, the shortage of  gasoline became even worse. There were altogether only 12,500 tons in  Guilin and Liuzhou airports. To avoid being attacked at the airport  some more planes flew back to Kunming. For five days American planes  were grounded. On the east front, only the 5th Fighter Group could  take off to fight. Thus at a critical moment, American air force not  only lost its opportunity to support Chinese ground force, but also  suffered attack from Japanese air force. On July 23, 90th Division of  Japanese air force shifted to Guangdong, the main targets of which  were the American bases in Guilin and Liuzhou. On the same day,  Japanese planes destroyed 18 American planes during their raid on  Lingling airport. Five days later, they destroyed 36 American planes  in Liuzhou. Japanese planes also raided airports in Zhijiang and  Guilin later. At the same time, Japanese ground forces intensified  their attack on Hengyang under air cover. When sufficient gasoline was  brought to American front base the Japanese had already taken Hengyang  on August 8.$ After the fall of Hengyang, the situation in East China became more  serious. The American air force, after being replenished, returned to  the east front and conducted fierce booming raids. Estimated by the  Japanese army, more than 1000 sorties in 171 groups took place in  Central China. All these finally helped American Air Force to gain air  control in the battle field. For the period after that, American Air  Force tried to stop the Japanese from advancing southward through air Šattack and achieved some results. For example, on September 4, the  58th Division of the Japanese army was raided by American air force  several times near Baidi city. The Japanese army acknowledged that,  "the troops suffered great losses and the advance was halted."#+[43] On  the same day, troops under the 13th Division of the Japanese army in  Qiyang all suffered considerable casualties due to the air raids.  Nevertheless, though the bombing of American Air Force could slow the  speed of advance of the Japanese army temporarily, it could not change  the situation totally. On September 6 the Japanese army occupied  another front base of the American air force--Lingling airport.$ After that the Japanese army began its preparation for the last stage  of No.1 plan--the Battle of Guangxi. During this period, the  Headquarters of the Japanese army were still worried about the  American air force which would fly eastward to threaten Japan proper  and the sea transportation between important places in the south. So  it demanded that the Japanese army in China remove this threat.#+[44]  However, they did not reach this goal even after the Japanese occupied  Guilin and Liuzhou on Nov.11. That is because except for 7 airports  and 6 auxiliary runways that were occupied by the Japanese in the Yu- Gui-Xiang Battle, the main strength of American Air Force did not  suffer any severe loss. On the contrary, as Chennault remarked, all  these "did not stop the 14th Air Force from fighting or diminishing  our intensity of fighting." In fact, the 14th Air Force had made new  deployment under the leadership of Chennault after the fall of front  bases in southeastern China. The Deployment was as follows: (1) to  reinforce the airports in Xi'an, Ankang, Hanzhong of Shaanxi Province  and various airports in Sichuan Province. The air force's major task  there was to defend Chengdu airport, cut off Tongpu, Longhai, Jinpu  and Jingsui railroads; (2) to enlarge and strengthen Laohekou and  Zhijiang airports northwest and southwest of Hankou. The Chinese- American Composite Division was to station here and their main task  was to destroy bridges over the Yellow River and the Japanese  facilities along Jin-Han railway, and to attack the Nanjing-Shanghai  area; (3) to divide the 68th Wing of the air force into two parts. One  part including the Wing Headquarters and two squadrons stationed at a  series of new airports 100 li east of Kunming. Their task was to  support the Chinese forces along Guangdong-Hankou railway and cut off  the transportation line between south China and southeast Asia. The  other two squadrons moved to areas east of the Japanese occupied  regions. They stationed at Yichuan, Ganzhou and Nanxiong airports and  established East China Mobile Air Force. Chennault demanded that this  mobile force should guarantee the security of airports in east China  and attack ships in Shanghai, Nanjing and on the Yangtze River. In  this way, the 14th Air Force succeeded in setting up a new battle line  almost parallel to Guangdong-Hankou railway from south to north and  coordinating with Chinese ground forces.$ During this period, the supplies and equipment of the 14th Air Force  had been greatly improved. In the last three months in 1944, it could  receive 9274 tons of gasoline and lubricant each month.#+[45] Besides,  combat planes also increased both in quantity and in quality.  Therefore, American Air Force in China had the ability to launch air  attacks in every region. East China Mobile Air Force got involved in  attacking fortresses and strongholds from November 1944 to February  1945 with the help of the provisions line between Zhijiang, Ganzhou  and Suizhou. They flew 747 sorties and dropped 110 tons of explosives Šand damaged 312 Japanese planes.#+[46] The Chinese-American air force  in central China bombed Hankou on December 18, giving the major  Japanese air base in central China a devastating blow. On January 17,  they air raided Shanghai and made Japanese air force in Shanghai lose  65 aircraft. In February, American air force in China concentrated all  their forces on cutting off transportation lines. They destroyed 37  bridges and 142 vehicles.#+[47]$ The American attacks forced Japan to readjust their air army in China.  But Japanese forces could not retrieve themselves from an inferior  position. In addition to this, the Japanese also had to defend their  homeland. So they had to recall some air divisions. The Japanese air  force was incapable of taking care of battles on mainland China and  "could only fight at minimum degree".#+[48] In March, 1945, the  Japanese aircraft on mainland China reduced in sorties and had no  ability to counterattack American air force. Thus, the Japanese army  finally lost their air battle capability and stopped their air  operation in reality five months prior to formal surrender.$ Through the brief review, it is not difficult for us to conclude that  during the four years' air battle against the Japanese, American air  force staff effectively cooperated with Chinese ground forces in  combats, captured air control in China and helped the Chinese air  force tie over its "dark era". Furthermore, American participation  greatly inspired the Chinese people. Nevertheless, during WW II the  U.S. adhered to the strategy of Europe first, so the development of  this unit of the American air force in China was limited and may not  be satisfactory at all times. However, only by taking all difficulties  into consideration could we understand its precious contributions to  China's anti-Japanese war. We should also be positive in evaluation of  General Chennault's contribution to the anti-Japanese war, for he had  led and directed the air force from beginning to end. Finally, we  should also point out that the achievement of the American air force  in China not only resulted from their own efforts, but also from the  great efforts of the broad masses of the Chinese people. This was not only  shown in the construction of airports, defence of airports, and  provision of air defence intelligence which was praised by Chennault  himself, it was also shown through the cooperation of the Chinese air  force.$ #T4NOTES#t ##[D1J100P80] _#+[1]_The U.S. State Department ed., #FKRelations Between China and  the U.S.#FS_ (Wenhai Publishing Company Ltd., Taiwan, 1984), p.25.$ _#+[2]_According to the research done by Liu Fu, an American Chinese,  the annual output of crude iron in 1936, was only 870,000 tons, daily  production of oil was several hundred jins.
