The brigade served with the 1st Indian Cavalry Division on the Western Front and the brigade commander acted as Commander Royal Horse Artillery (CRHA).[7] In practice, the batteries were permanently assigned to the cavalry brigades, viz:[8]
Other than the Battle of Cambrai when it helped to told the German counter-attack, the division was not involved in battle. Instead, it was held in reserve in case of a breakthrough, although it did send parties to the trenches on a number of occasions. They would hold the line, or act as Pioneers; such parties were designated as, for example, the Mhow Battalion.[9]
XVI Brigade, RHA
On 26 November 1916, 1st Indian Cavalry Division was renamed 4th Cavalry Division.[8] Consequently, on 24 February 1917, the brigade was redesignated as XVI Brigade, RHA.[10]
In March 1918, the 4th Cavalry Division was broken up in France. The British units remained in France and the Indian elements were sent to Egypt to help constitute 1st Mounted Division.[9] The brigade became XVI Army Brigade, RHA.[b][3] About this time the brigade's 13 pounders were replaced by 18 pounders. At the Armistice, it was serving as Army Troops with the Fourth Army[11] commanding A, Q, and U Batteries, RHA (eighteen 18 pounders).[12] The brigade moved to Germany as part of the Army of Occupation.[13]
^The basic organic unit of the Royal Artillery was, and is, the Battery.[1] When grouped together they formed brigades, in the same way that infantry battalions or cavalry regiments were grouped together in brigades. At the outbreak of World War I, a field artillery brigade of headquarters (4 officers, 37 other ranks), three batteries (5 and 193 each), and a brigade ammunition column (4 and 154)[2] had a total strength just under 800 so was broadly comparable to an infantry battalion (just over 1,000) or a cavalry regiment (about 550). Like an infantry battalion, an artillery brigade was usually commanded by a Lieutenant-Colonel. Artillery brigades were redesignated as regiments in 1938.
^Army Brigades, RHA and RFA were artillery brigades that were excess to the needs of the divisions, withdrawn to form an artillery reserve.
