This short documentary made in 2008 looks at the gruelling life of a soldier in the First World War. The letters home speak of the physical and emotional hardships and the mental strain of what they witness on the battlefield. On the 11th hour of the 11th day of the 11th month of the year 2008, 90 years will have passed since the signing of the Armistice ending the Great War in Europe. More than 600,000 men and women crossed the Atlantic with the Canadian Expeditionary Force, and more than 60,000 of them never returned. Front Lines features veterans' letters to their families and images from the NFB archives, the Canadian War Museum and Library and Archives Canada.
