Question: How long had the Second World War been going on before the Normandy landings? Passage:He was back in Toronto in 1939 when the Second World War broke out. He attempted to join the Royal Canadian Navy (RCN), but anti-semitism in the RCN at the time precluded a naval career. Instead Dunkelman enlisted as a private with The Queen's Own Rifles of Canada; as the war progressed he rose from Private to Major. He was in the second wave to land on Juno beach, the Canadian beach in the Normandy landings on D-Day 6 June 1944. During his career with the regiment he earned numerous commendations and a Distinguished Service Order (DSO) for his service in the Hochwald campaign. He also fought in the difficult earlier campaigns in northern France, Belgium, the Netherlands and Germany, including bloody battles at Caen, Falaise, and the Battle of the Scheldt Estuary that led to the critical port of Antwerp.
