The remaining portions of Indochina remained the responsibility of the Agency's U-2s. Then in August 1964, following the Gulf of Tonkin Resolution, the Air Force assumed responsibility for all of Indochina:5 U-2s in India In October 1962, the People's Republic of China launched a series of massive surprise attacks against India's frontier forces in the western provinces of Jammu and Kashmir and in the North-East Frontier Agency (NEFA). The Chinese overran all Indian fortifications north of the Brahmaputra Valley before halting their operations. The Indian Government appealed to the United States for mili tary aid. In the negotiations that followed, it became apparent that Indian claims concerning the extent of the Chinese incursions could not be reliably evaluated. US Ambassador John Kenneth Galbraith, therefore, suggested to the Indian Government that US aerial recon _naissance of the disputed areas would provide both governments with a more accurate picture of the Communist Chinese incursions. On 11 November 1962, Prime Minister Jawaharlal Nehru consented to the proposed operation and gave the United States permission to refuel the reconnaissance aircraft (U-2s) in Indian airspace:6 In late November, Detachment G deployed to Ta Khli, Thailand, to carry out the overflights of the Sino-Indian border area. Since the U-2s were not authorized to overfly Burma, they had to reach the tar get area via the Bay of Bengal and eastern India and, therefore, re quired midair refueling. Because of severe winter weather conditions, the first flight did not take place until 5 December. Poor weather and air turbulence hampered the mission, and only 40 percent of the target area could be photographed. A second mission on 10 December was more success ful, but the U-2 experienced rough engine performance because of icing of the fuel lines.47 " OSA History, chap. I 6, pp. 18- I 9 (TS Codeword).
