On 31 March 1918, in what is known as "the last great cavalry charge" at the Battle of Moreuil Wood, Lieutenant Gordon Flowerdew was posthumously awarded the Victoria Cross for leading the charge in a successful engagement with entrenched German forces. Nearly three-quarters of the Canadian cavalry involved in the attack against German machine-gun positions were killed or wounded. Unable to break the trench deadlock and of little use at the front, cavalry remained behind the lines for much of the war. During the German offensives of March and April 1918, however, the cavalry played an essential role in the open warfare that temporarily confronted the retreating British forces.
