The 9th Jats were an Indian Army regiment first raised by the East India Company in 1803 as the 22nd Bengal Regiment of Native Infantry. The unit was immediately plunged into the Mahratta wars, before embarking on the first Afghan War, the Sikh Wars and the Burma wars. During the Indian Mutiny, the regiment remained relatively inactive, although their British officers took part in the mutiny's suppression. Between the mutiny and the Great War the unit was involved in fresh fighting in Burma, Assam, Somaliland and the Boxer Rising in China. The regiment went to France on the outbreak of war in 1914, but their sojourn in the trenches was brief, and they were soon in Egypt training for the war in Mesopotamia (Iraq). After the war, the regiment took part in the third Afghan war and the tribal fighting in Waziristan. This is a full and account of a distinguished Indian regiment, and is accompanied by appendices listing the regiment's honours, awards and colours, and by four illustrated plates and six maps.
