(as many planners had feared it would). The Royal Canadian Air Force (RCAF) sent 230 bombers to bomb targets on Juno during this raid, yet damage was limited. As the Americans began their own bombing runs against Omaha and Utah to the west, the Anglo-Canadian naval forces began their counter-battery fire, seeking to knock out German shore batteries and bunkers. The British had attached the cruisers and to Force J to serve as heavy support. Belfast commenced bombardment of the Atlantic Wall at 05:30 and Diadem at 05:52 on 6 June. The naval gunfire proved more effective than the aerial bombardment; the battery at Longues was the only one to return fire, and was quickly destroyed by the light cruiser . Indeed, most of the gun batteries at Juno were incomplete on D-Day, and did not possess sufficient protection or communication measures to accurately return fire on Force J. The Bény-sur-Mer battery was neutralized by Diadem shortly after she opened fire. At 06:10, the 11 destroyers of Force J moved shoreward to begin bombardment, hoping to damage light gun emplacements and prevent the German 716th from mobilizing and moving across the beach. They were supplemented by additional raids by medium bombers and fighter-bombers of the RAF and USAAF, which dropped an additional 2,796 tons of ordnance on the five landing zones. While the medium bombers proved inaccurate, the Hawker Typhoon fighter-bombers proved more effective at attacking coastal defences. As the bombing runs continued to hit Juno, the destroyers and landing craft moved towards the beach and began close-range saturation bombardment. In addition to the destroyers of Force J—two Canadian, eight British, one French—bombardment was also provided by converted LCTs fitted with guns. Smaller, light-gunned landing craft were able to get closer to the beach and use their 6-pounder guns against German defensive positions. Additional firepower was provided by eight landing craft fitted with over 1,000 high-explosive rockets and 24 LCTs, each carrying four M7 Priest self-propelled guns. These field regiments, while still seaborne, were to fire heavy concentrations of high explosive and smoke shells against the four main "resistance nests" in "Mike" and "Nan" sectors, beginning half an hour before H Hour. Forward observation and fire control officers in the leading assault waves were to make the necessary adjustments to this neutralizing fire during the assault. The bombardment was scheduled to cease immediately before the assault companies deployed on Juno, but due to heavy seas, the landing was delayed by ten minutes, to 07:45 in Mike sector and 07:55 in Nan Sector. This was at a slightly higher tide, closer to the beach obstacles and mines. The LCTs carrying the field artillery were forced to adjust course to avoid landing too early; the LCTs carrying DD tanks were forced to break off their advance. The seas proved too rough to launch the DD tanks, so they were ordered to deploy from the LCTs several hundred yards out from the beach. Landing: 7th Brigade (Mike, Nan Green) Though the 7th Canadian Infantry Brigade was scheduled to land on Mike Sector at 07:35, rough seas and poor craft co-ordination pushed this time back by ten minutes. Two assault companies of the Royal Winnipeg Rifles, one assault company of the Canadian Scottish Regiment, and one squadron of the 1st Hussars were to land on "Mike Red" and also on "Mike Green", while the Regina Rifle Regiment, supported by a second squadron of the 1st Hussars, landed on "Nan Green" sector. The first Winnipegs touched down at 07:49, with the remaining assault companies deploying within seven minutes. The LCAs carrying "B" Company craft were
