After being assessed as unfit to fight at the outbreak of the First World War, Munnings was assigned a civilian role processing thousands of Canadian horses en-route to France instead. He was soon enlisted as a war artist to the Canadian Cavalry Brigade, during which he painted many cavalry scenes including the ‘Charge of Flowerdew’s Squadron’ at the Battle of Moreuil Wood in 1918 – which became known as the last great cavalry charge. The painting is displayed in the Canadian War Museum, Ottawa, alongside many other Munnings works from this period.
