In the 1890s all the major European armies began to use small-bore, bolt-action rifles that fired multiple rounds from a spring-loaded clip inserted into the magazine. The Lee-Enfield was first introduced in 1907 and by the outbreak of the First World War, was the British Army's main infantry weapon. It was estimated that the highly trained British Expeditionary Force that arrived in France in September 1914, were able to fire 15 rounds per minute. The Lee-Enfield could be aimed accurately over about 600 metres but could still kill someone over 1,400 metres away.
