The Kaiser's battle

At 9.30am on 21 March 1918, the last great battle of World War I commenced when three german armies struck a massive blow against the weak divisions of the British Third and Fifth armies. It was the first day of what the Germans called the kaiserschlact (the kaiser's battle), the series of attacks that were planned to break the deadlock on the western front, knock the British Army out of the war and finally bring victory to imperial Germany. Through first-hand accounts by survivors of the battle, Martin Middlebrook discusses the battle.
