The Maxim machine gun was a weapon invented by American-British inventor Hiram Stevens Maxim in 1883: it was the first recoil-operated machine gun. By World War I, many armies had moved on to improved machine guns. The British Vickers machine gun was an improved and redesigned Maxim, introduced into the British Army in 1912 and remaining in service until 1968. Production took place at Erith in Kent and some models were fitted to early biplanes also fabricated there. The German Army's Maschinengewehr 08 and the Russian Pulemyot Maxim were both more or less direct copies of the Maxim. It also saw use during the Russian Civil War, which followed the Revolution in 1917. A picture of the period depicts a Maxim gun mounted on a tachanka, a horse-drawn carriage, along with the gunner, firing backwards at a pursuing White Army regiment.
