The First World War tank developed from the interest of some military officers in the marriage of tractors with caterpillar tracks as a means of crossing trench obstacles and breaking through barbed wire.

Deep trenches and dug-outs protected against artillery.The riddle of the trenches was to find a way to overcome the power of the defender. The British turned to armoured vehicles as one way to cross No Man’s Land and break through the enemy trench system. Barbed wire and machine-guns stopped many Allied attacks with heavy casualties in 1915 and early 1916.
