The Group deployed to CBI during November over the South Atlantic transport route starting at Morrison Field, Florida.

Upon arriving at Sylhet Airfield, India on 28 November 1944, initial flying consisted of air-lifting tar and other airport construction materials from the upper Assam Valley to recently recaptured Myitkyina in northern Burma.

The 4th Group started moving supplies into Imphal, India, to develop stockpiles of materiel for the XIV Army imminent drive south.

During this period, the XIV Army had progressed south to the Kabaw Valley and supplies were air-lifted over the 10,000-foot mountains to dirt airstrips quickly hacked out of the jungle.

Operations included moving equipment and materials for the Ledo Road; transporting men, mules, and boats when the Allies crossed the Irrawaddy River in February 1945; and dropping Gurkha paratroops during the assault on Rangoon in May 1945.
