Assam tea
Dinjan Airfield was built on an Assam tea plantation by thousands of plantation laborers, beginning in March 1942, as a result of the Japanese invasion of Burma in December 1941. It opened in the spring of 1942 with No 5 Squadron RAF and a squadron of Curtis Mohawk fighter aircraft, which remained until the Autumn of 1942 before moving to Agatala; This unit's primary mission was the protection of cargo aircraft flying over The Hump from nearby Chabua Airfield to China.
