QF 3.7-inch mountain howitzer
Ordnance, QF 3.7-inch howitzer is a mountain gun, used by British and Commonwealth armies in the First and Second World Wars, and between the wars.
The British Indian Army first requested a modern mountain gun in 1906 to replace the BL 10 pounder Mountain Gun, which had been hastily developed after the Second Boer War, but had several shortcomings. In particular, the shell weight was seen as too light, and the gun lacked any recoil absorber or recuperator, meaning the gun had to be relaid after every shell was fired. However, financial constraints delayed production of the 3.7-inch weapon until 1915. As a stop-gap, the barrel of the 10-pounder gun was mounted on an updated carriage to produce the 2.75 inch Mountain Gun.
The 3.7-inch howitzer was first introduced in 1917, and was used in action in that year in the Mesopotamian Campaign (modern Iraq area).
The 22nd (Derajat) Indian Frontier Force mountain battery arrived in the East Africa campaign on 18 December 1916, when they relieved the 28th Battery which returned to India. They appear to have re-equipped from the 10-pounder mountain gun to the 3.7-inch howitzer while in East Africa, and first used the new weapon in action in an attack on German positions at Medo, 11 April 1918.
The 3.7-inch howitzer superseded the 2.75-inch mountain gun following the First World War. It was used by mountain artillery regiments of the Royal Artillery and the Indian Artillery, and saw much service on the North West Frontier of India between the wars.
During the Second World War, the weapon equipped artillery units engaged in the North African Campaign (Tunisia), the Italian Campaign, the Kokoda Campaign, and Burma Campaign, and was also used in the Netherlands and Ruhr fighting in 1944–45 by units originally destined for mountain warfare in Greece. In the latter theatre, on occasion the gun was dismantled and manually hauled up to the upper floors of buildings to provide close support in urban fighting. A lightened version was used briefly by airborne formations. Several were supplied to the French Army after 1945; one is on display at the Vietnam Army Museum in Hanoi while another is displayed at the Zone 5 Military Museum, Danang. It was also used on Close Support versions of the A9 and A10 Cruiser Tanks in place of the standard 2 pounder, though mostly to fire smoke shells.
During the war the gun, and its ammunition, were also manufactured in other Commonwealth countries, including South Africa, by the ISCOR (Iron and Steel Corporation of South Africa), and India. South Africa also produced modified versions of the gun.
The gun was finally declared obsolete by the British Army in 1960, although it had not seen service since 1945.
