The 1st (Peshawar) Division was a Regular Division of the British Indian Army formed as a result of the Kitchener reforms of the Indian Army in 1903. During World War I, the Division remained in India for local defense, but was mobilized for action on the North West Frontier on several occasions. The Division was a part of the Northern Army, later called the Northern Command. In 1919, the Division was mobilized for operations in Afghanistan during the Third Afghan War. Typical of most Indian Army formations, it contained a mixture of British and Indian units; but, unlike British Divisions, it contained a mixture of cavalry and infantry components.
