The South Asian contingent comprised mostly Sikh and Gurkha who fought in three streams: the 29th Indian Brigade, the Indian Mountain Artillery Brigade and the Indian Mule Corps.
The role of these soldiers has largely been overlooked in Australian and New Zealand accounts of Gallipoli. In a soon to be published book. Professor Stanley, a military historian at the University of New South Wales argues that three times as many South Asians fought in the campaign than official estimates suggest. Historical record has long put the number of Indian troops at Gallipoli at 5000 but Professor Stanley says he has found that the actual figure exceeded 15,000.
