The first Indian troops involved in the initial landings on the Gallipoli peninsula in April 1915 were the 21st Kohat Mountain Battery and the 26th Jacob’s Mountain Battery. Although the landing was met with heavy firing and fierce counter-attack from the Turks, many Indian soldiers were recognised for their gallantry and won medals and distinction. In May 1915, the 29th Indian Infantry Brigade arrived on the peninsula, comprising 14th King George’s Own Ferozepore Sikhs, 89th Punjabis, 1/5 Royal Gurkha Rifles (FF), and 1/6 and 2/10 Gurkha Rifles. On 4 June 1915, the 14th Sikhs comprising 15 British Officers, 14 Indian Officers, and 514 men, moved out to attack and capture Turkish trenches.
They held on to the trenches, suffering heavy losses until they were relieved next morning. On the morning of 5 June 1915, only 3 British Officers, 3 Indian Officers, and 134 men were left. The 14th Sikhs won great glory in this advance and several soldiers won the Indian Distinguished Service Medal. In the attack on Sari Bair, the Indian Infantry and Artillery were entrusted with the task of storming Chunuk Bair. The Indian troops were the only ones to reach the crest of the Chunuk Bair.
The performance of the 14th Sikhs in the assault of Koja Chaman Tepe, which they failed to reach, was described by General Birdwood as “a feat which is without parallel”. Though no decisive result was obtained and the Allies had no substantial gains from the Gallipoli campaign, the Indian troops, including the Medical Services, displayed great bravery and courage in the rest of the operations on the peninsula and several were granted the Indian Order of Merit.
