With the division, the brigade took part in the Actions for Nasiriya (5, 1314, 24 July) and the Occupation of Nasiriya (25 July) in 1915 and the Affair of Butaniya on 14 January 1916. The division never reached full strength as units were constantly detached to support the efforts to relieve the 6th (Poona) Division besieged at Kut. The division was broken up on 10 March 1916 and the brigade was posted to the new 15th Indian Division in May 1916.
