The Japanese did not invade India in 1942 as had been feared. V Force was able to consolidate itself in the wide area between the Allied and Japanese main forces. Bases and outposts were set up, standing patrols instituted and intelligence gathered and collated. By the end of 1943, the force had been reorganised into two main zones: Assam Zone, including Imphal and all the frontier north of it, and Arakan Zone to the south. Detachments in Tripura were disbanded as they were deep inside India and unlikely to be threatened. An American organisation (OSS Detachment 101) later took over the northernmost areas around Ledo.
