Wait for Me, Daddy
Wait for Me, Daddy is a photograph taken by Claude P. Dettloff of the British Columbia newspaper The Province. It depicts a column of Canadian Army soldiers of the British Columbia Regiment (Duke of Connaught's Own) marching in New Westminster on October 1, 1940. In the foreground, five-year-old Warren "Whitey" Bernard runs out of his mother's reach towards his father, Private Jack Bernard. The photograph received extensive exposure worldwide, and was used in Canadian war-bond drives.Photograph credit: Claude P. Dettloff; restored by Yann Forget
