This brigade was the renaming of what had for a time simply been known as the “4.5-inch howitzer brigade”.
It was made up of a small brigade headquarters, 60th (Howitzer) Battery, 61st (Howitzer) Battery, and a Brigade Ammunition Column.
The two batteries had gone to France and served as part of the artillery of 3rd (Lahore) Division. When that formation left France for service in Mesopotamia, it left most of its artillery behind but these batteries accompanied it . 60th sailed on the “Anglo-Egyptian”, leavng Marseilles on 20 December 1915 and going via Toulon, Malta, Alexandria, and Port Said, it landed at Magil in Mesopotamia on 15 January 1916. 61 Battery had arrived at the same place on 1 January.
The batteries joined the Tigris Corps and moved upriver, participating in the British effort to relieve the besieged 6th (Poona) Division at Kut-al-Amara. The batteries took part in actions at Sheikh Sa’ad, the Hanna and the Wadi.
On 2 May 1916, after Kut had been surrendered, the batteries formed the “4.5-inch howitzer brigade”. Headquarters staff of officers and men arrived from 69 Brigade RFA. The brigade remained in action with the Tigris Corps. The movements and actions of the brigade can be traced in war diary National Archives reference WO95/5078.
The change of name to 134th Brigade RFA took place on 13 November 1916.
On 17 and 18 June 1917, the two batteries and ammunition column left to join the 13th (Western) Division.
On 25 June, 134th ceased to exist as such, the headquarters becoming the HQ of 3rd Corps Artillery Group.
