The Brigade was divided into three battalions under the command of Shah Nawaz Khan. By the beginning of January 1944, it had reached Rangoon in Burma, where two battalions remained to guard the border between Burma and India near Haka while the third advanced into India across the Kaladan River. Elements of the Brigade subsequently took part in the Battles of Imphal and Kohima, where they were forced to withdraw alongside the Japanese forces they supported. These battles marked the turning point in the Burma Campaign.
