After consultation among the Allied governments, Air Command South-East Asia was formed in November 1943 to control all Allied air forces in the theater, with Air Chief Marshal Sir Richard Peirse as Commander-in-Chief. Under Peirse's deputy, USAAF Major General George E. Stratemeyer, Eastern Air Command (EAC) was organized in 1943 to control Allied air operations in Burma, with headquarters in Calcutta. Unlike the strained relations and confusion encountered in coordinating Allied ground force commands, air force operations in the CBI proceeded relatively smoothly. Relations improved even further after new U.S. military aid began arriving, together with capable USAAF officers such as Brigadier General William D. Old of CGI Troop Carrier Command, and Colonels Philip Cochran and John R. Alison of the 1st Air Commando Group. Within Eastern Air Command, Air Marshal Sir John Baldwin commanded the Third Tactical Air Force, originally formed to provide close air support to the Fourteenth Army. Baldwin was later succeeded by Air Marshal Sir Alec Coryton. U.S. Brigadier-General Howard C. Davidson and later Air Commodore F. J. W. Mellersh commanded the Strategic Air Force. In the new command, various units of the Royal Air Force and the U.S. Tenth Air Force worked side-by-side. In the autumn of 1943 SEAAC had 48 RAF and 17 USAAF squadrons; by the following May, the figures had risen to 64 and 28, respectively.
