The First World War is tremendously significant to India’s history. Largely considered a European war, it actually involved the participation of more than a hundred countries, allowing for it to be also known as, The Great War. Indian soldiers were sent to fight alongside the British in Mesopotamia (modern-day Iraq), Egypt, Palestine, France, Aden, Belgium, East Africa, Gallipoli and Salonika. About twenty-five princely states contributed over 26,000 combatants. They accompanied Britain’s soldiers in the artillery, cavalry, infantry, engineers, signals service, sappers, and miners, arms of the army. Indian services to Britain extended to the Royal Navy as well as the Queen Alexandra’s Imperial Military Nursing Service. Indian troops who fought in Europe, had stepped outside their homeland, across the kala pani, for the first time. The drastically different landscape and colder weather was a shock as well. Socially too, they felt displaced among the Europeans, with their vastly different cultures and mannerisms. This was a very new scenario for Indian men; to fight side-by-side the people who were their colonisers back home. The entire experience of fighting overseas was culturally alienating for many Indians, as mentioned in their letters home, which were also often subject to military censorship. Though mentally ill-equipped to deal with an emotional and physical relocation as vast as this, Indian soldiers fought valiantly. Inder Singh, in a letter back home from the Somme in September 1916, wrote, ‘It is quite impossible that I should return alive. [But] don’t be grieved at my death, because I shall die arms in hand, wearing the warrior’s clothes. This is the most happy death that anyone can die’. By the end of the war, about 60,000 troops from India had fought for Britain. The author, Captain Amarinder Singh is himself a product of the Indian army. He served as ADC to the GOC-in-C, Western Command, during the 1965 war with Pakistan. A published military historian, he painstakingly retraces the footsteps of the Indian battalions during the First World War, using official battle details, war diaries, and maps.
