The troops were taken out of the line and rested in early 1915, but were soon back in the trenches and involved in the heaviest fighting. The Indian Corps provided half the attacking force at the Battle of Neuve Chapelle in March, and the Lahore Division was thrown into the counter-attack at the Second Battle of Ypres in April. Morale seemed to pick up in the spring of 1915, only to decline towards the end of the summer when it became clear that an end to the war was not in sight. The Indians again took heavy losses at the Battle of Loos in September.
The two Indian infantry divisions were withdrawn from France in December 1915, and sent to Mesopotamia. Arguably they were moved because their morale was fragile, and it was thought unwise to expose them to another winter on the Western Front. But it also made strategic sense to concentrate the Indian Army in the Middle East, where it was easier to send reinforcements and supplies from India. Two Indian cavalry divisions remained on the Western Front until March 1918, when they were transferred to Palestine to take part in the offensive against the Turks.
