I Corps (British India)

The I Indian Corps was an army corps of the British Indian Army in World War I. It was formed at the outbreak of war under the title Indian Corps from troops sent to the Western Front. The British Indian Army did not have a pre-war corps structure, and it held this title until further corps were created. It was withdrawn from the Western Front in December 1915 and reconstituted as I Indian Corps in Mesopotamia until the end of the war.
In 1914 Indian Expeditionary Force A was sent to reinforce the British Expeditionary Force (BEF) fighting in France. In France it formed the Indian Cavalry Corps and Indian Corps composed of 3rd (Lahore) and 7th (Meerut) Divisions. (In France, these formations were simply known as 'Lahore' and 'Meerut' Divisions, to distinguish them from the 3rd and 7th British divisions.) Despatch from India was delayed by the activities of the German raiders Emden and Königsberg operating in the Indian Ocean, and by the slow speed of the transport vessels. Lahore Division began landing at Marseilles on 26 September 1914, but there were further delays while the troops were re-armed with the latest pattern rifle, and the supply train could be improvised, using tradesmens' vans procured locally. The corps finally got into action at the Battles of La Bassée, 1st Messines and Armentières in October–November 1914.

On 13 August 1915, General Sir John Nixon, commanding Indian Expeditionary Force D in Mesopotamia, requested one of the Indian infantry divisions in France as reinforcements for his advance on Baghdad. Coincidentally, on the same day, the Secretary of State for India, Austen Chamberlain, told the Viceroy of India that he was anxious for the Indian infantry to be withdrawn from France before they had to endure another winter. The system for supplying drafts had broken down and the Indian battalions were becoming very weak after the heavy casualties they had suffered. Although the Secretary of State for War, Lord Kitchener, objected to their withdrawal from the Western Front, orders were issued on 31 October for the two divisions of Indian Corps (3rd (Lahore) and 7th (Meerut) Division) to embark at Marseilles for Mesopotamia. Indian Corps was relieved in the front line on 6 November by XI Corps and the two divisions were due at Basra in December, but their departure from Marseilles was delayed because of fear of submarine attack. 3rd (Lahore) Division finally arrived in Mesopotamia in April 1916 and joined Tigris Corps, too late to relieve 6th (Poona) Division at Kut-al-Amara.
