It was assigned to Indian Expeditionary Force B along with 27th (Bangalore) Brigade. The Force sailed from Bombay (Mumbai) on 16 October with Tanga in German East Africa as the target for an attack. After the failure of the Battle of Tanga (2–5 November), the Force disembarked at Mombasa and joined the defences of British East Africa. The brigade was broken up at this point.^[1]
