CHINA-BURMA-INDIA (CBI) THEATER OF OPERATIONS
"The Hump" was a high altitude military aerial supply route between the Assam Valley in northeastern India, across northern Burma, to Yunnan province in southwestern China, flown during World War II. This operation was the first sustained, long range, 24 hour around the clock, all weather, military aerial supply line in history. It was a start-from-scratch operation. There was no precedent for it.
