British forces deploy tanks for the first time in warfare during the Battle of Flers-Courcelette, part of the wider Battle of the Somme, on 15 September 1916.
The first tanks in warfare were introduced by Britain in an attempt to break through German defensive positions on the Western Front during the First World War.
Britain deploys the Mark I
The British Army sent its new Mark I tanks into battle at Flers-Courcelette. The vehicles had been developed in response to the trench warfare that had created heavily fortified and difficult-to-cross front lines.
The tanks were designed to cross trenches and withstand small-arms fire while supporting infantry advances. They were divided into two main versions: the “Male” variant, equipped with heavier guns, and the “Female” variant, which carried machine guns.
Among the early prototypes was the vehicle known as “Little Willie”, an important stage in the development of Britain’s tank programme. The Mark I represented the first operational tank design used in combat.
A new era of warfare
The deployment on 15 September 1916 marked a major technological development in land warfare. Although the tanks faced mechanical problems, difficult terrain and other limitations, their appearance demonstrated the potential of armoured vehicles on the battlefield.
The Battle of Flers-Courcelette formed part of the Somme offensive, which had begun in July 1916 and continued until November.
The introduction of tanks would influence military strategy in the years that followed, eventually making armoured warfare a central element of modern military operations.
