Lewis Gun, The

As a lightweight machine gun, the American designed Lewis Gun made a place for itself in World War I & World War II.

Although machine guns were widely issued and used during the bloody opening months of World War I, these deadly weapons proved to be too heavy to be tactically mobile. Casting around for existing designs to supplement inadequate stocks of the excellent Vickers gun, the British adopted the US-designed Lewis gun, which had not found favor with the US Army. The British quickly came to realize that while the new weapon was unable to match its heavier cousin in terms of robustness and sustained firepower, its light weight and the fact that it could be fired both prone and on the move made it an ideal weapon both to support advances and defend captured trenches. Serving on the Western Front and across the world, the Lewis gun soon became the core of the British and Dominion infantry section, and was widely adopted by the Germans too; even so, the US Marine Corps found on landing in France that their Lewis guns were replaced by an inferior French weapon, the CSRG 'Chauchat'.
