The U Go offensive, or Operation C (Japanese: ウ号作戦, U Gō sakusen), was the Japanese offensive launched in March 1944 against forces of the British Empire in the northeast Indian regions of Manipur and the Naga Hills (then administered as part of Assam). Aimed at the Brahmaputra Valley, through the towns of Imphal and Kohima, the offensive along with the overlapping Ha Go offensive was one of the last Japanese offensives during the Second World War. The offensive culminated in the Battles of Imphal and Kohima, where the Japanese and their allies were first held and then pushed back.
