unit, the 4th Highland (Mountain) Brigade, Royal Garrison Artillery (Argyllshire and Ross & Cromarty Batteries with 4 guns each) at Helles and then Suvla. The 21st Battery was granted the title "Royal" in 1922 for its actions including Gallipoli, unique for an artillery battery. There is some evidence that the Turkish defenders on Gallipoli were also using the 10 pounder, bought prewar from New Zealand, as the ANZACs discovered 10 pounder shell bodies fired at them made in India which were not from their own guns. In the East Africa campaign, the following Indian batteries used the 10 pounder with distinction in constant action :- * 27th Mountain Battery (6 guns), part of the Indian Expeditionary Force C, from 27 August 1914 to 2 January 1918. * 28th Mountain Battery with 6 guns arrived with Indian Expeditionary Force B from 30 October 1914, returned to India December 1916. 28th Battery's first engagement occurred with the guns tied to the deck of HM Transport ship Bharata, firing in support of the unsuccessful British attempt to capture Tanga on 3 & 4 November 1914. Gunner Mehr Khan was awarded the Indian Distinguished Service Medal and Subadar-Major Nur Allam was awarded the Order of British India for their actions in 28th Battery defending Jasin on 18 January 1915. *1st Kashmir (4 guns) arrived 5 December 1916, returned to India 2 February 1918. Between them the 1st and 27th were awarded 2 Order Of British India, 1 Indian Distinguished Service Medal, 7 Meritorious Service Medals, 12 Mentioned in Despatches. * 24th Hazara Mountain Battery (Frontier Force) served in East Africa from 26 April 1917, taking up the 6 guns left by 28th Battery. A typical extract from their War Diary reads : "Ndundwala 2nd July 1917... one section came into action and fired 87 rounds shrapnel at enemy holding river crossing place at range 750 yards. Forward observer reported three direct hits on his breastworks. Sniping continued" 19 August 1917 : "constructed an emplacement within 150 yards of enemy... tubes which were dated 1901 are very bad and several misfires occurred... during last 15 days fired 548 shrapnel, 35 common and 4 star shells at average range of 1,000 yards". They returned to India in November 1918. * 22nd (Derajat) Mountain Battery (Frontier Force) arrived in the East Africa campaign on 18 December 1916, when they relieved the 28th Battery which returned to India. They appear to have initially used 10 pounders and re-equipped with howitzers some time later, as Farndale reports they first used their howitzers in action in the attack on German positions at Medo, 11 April 1918.Farndale 1988, page 351 They returned to India in November 1918. The gun was also used in the Palestine campaign.
