The Battle of Kohima was the turning point of the Japanese U-Go offensive into British India in 1944 during the Second World War. It took place in three stages from 4 April to 22 June 1944 around the town of Kohima, now the capital city of the state of Nagaland in Northeast India. From 3 to 16 April, the Japanese attempted to capture Kohima ridge, a feature which dominated the road by which the besieged British and Indian troops of IV Corps at Imphal were supplied. By mid-April, the small British and British Indian force at Kohima was relieved.
