A detachment of sailors from the HMCS Cabot will attend the annual ceremony at the National War Memorial. The Battle of the Atlantic was the largest ongoing military campaign in World War II, bringing the Royal Navy, the Royal Canadian Navy, the US Navy and the Merchant Navy against German U-boats and warships. The Germans targeted merchant ships and convoys crossing the Atlantic. German U-boats sank four iron ore vessels in Conception Bay just off Bell Island and torpedoed the Caribou, a heavy-duty passenger ferry in the narrow Cabot. A traffic jam will be set up on Water Street near the National War Memorial during the 10:00 a.m. ceremony. Officials monitor the weather with a final decision on the “go-or-no-go set” at 7:30 a.m. of Sunday CBS event CBS will also be hosting its own memory event. The event will also honor the Battle of Vimy Ridge, the Battle of Normandy D-Day, and Dean Darrell Cronin – a CBS member and member of the Armed Forces who died in 1998 on Tusker Flight 27. Also, Lt. Judy Foot will be on hand to present the Silver Crosses to two CBS residents: Audrey Mercer, Charles Mercer’s mother, and Donald Turner’s wife, Patricia Turner. The event will include a wreath-laying ceremony and a flight from the Canadian Armed Forces. It starts at 11:30 on Sunday morning.
