Nicknamed the 'mechanical monsters’, this photograph shows a British tank flanked by infantry soldiers, mules and horses. World War I has a notorious reputation for being the conflict that introduced the modern concept of mass slaughter by mechanical means. The dry and hard condition of the ground in this photograph looks like ideal terrain for tanks. It is likely that this photograph was taken by John Warwick Brooke. Originally deployed to end the stalemate of trench warfare, the muddy conditions meant that early attacks with tanks failed to achieve the desired breakthrough, as the tanks soon became bogged down. It was not until The Battle of Cambrai in November 1917, that tanks were used successfully in a major offensive, when the British finally broke through the German lines.
