By the middle of 1942, Japanese expansion in Burma had cut off the Burma Road, the last overland supply line to China.
The United State's priority in the China-Burma-India Theater was to keep China involved in the War with Japan, thus tying up the bulk of the Imperial Japanese Army in China, rather then in the Pacific Islands where most US combat occurred. To do this, the United States felt it imperative to open a supply line to China.

The Allies devised an alternative supply line, which included a long and dangerous airlife over the Hump, the popular name of a series of rugged mountains ranges in northern Burma and southwestern China.

In theory there was a preferable route over the Hump, the Low Hump Route from Calcutta to Kumning as shown on the accompanying low-resolution map. This route eliminated the need for long rail transportation and flew over lower mountains. However, it also flew over Japanese-occupied territory and thus was subject to air attack. Late in the war, as Japanese air power waned and the Japanese were pushed out of central Burma, it became feasible.
For most of its lifetime, the Hump airlift was operated by the United States Army Air Force Air Transport Command. Meanwhile, the 10th Air Force handled combat operations in India and Burma. |
Note on the accompanying map:

Although Hump operations began in mid 1942, infrastructure deficiencies in northeast India and limited American resources kept the Hump operation from reaching its goals until December 1943.
Until late in the war, Hump pilots had to fly over 15,000 foot ranges plagued with foul weather, since a more-direct route to the south was within range of Japanese interceptor aircraft. The Air Transport Command lost 600 aircraft in the Hump operation, with 1,500 air crew deaths. |
