The threatened invasion of India finally happened in 1944. The V Force detachments forward of Imphal were engulfed. They could provide some intelligence of Japanese moves during the invasion, but they lacked supplies (the local dumps had been drawn down over 1943) and there were too many demands on Allied transport aircraft to allow supply drops to them. As a result, they were unable to harass the Japanese lines of communication as had been planned, and had to disband or make their way back into Allied lines.
