In Nan Sector, the 8th Brigade advance started slower than that of the 7th Brigade, because the Chaudières had lost most of their equipment on the advance over the beaches. The Queen's Own Rifles' "C" Company was pinned down at the edge of Bernières by sniper-fire, and could not cross the open fields behind the town; their armoured support was also stopped by heavy antitank fire coming from Beny-sur-Mer. The Chaudières "A" and "B" Companies were caught in the crossfire; "B" Company lost almost an entire platoon when a German 88 mm scored a hit on a Priest self-propelled gun. Chaudière and QOR progress was slow; all told, it took nearly two hours for artillery and heavy guns to clear the defences at Beny-sur-Mer, allowing the QOR to advance towards the town. Beny-sur-Mer was reported cleared at 14:00, at which point the Chaudières began to mass in the town for a further advance south towards Carpiquet. The QOR broke off to the left to engage heavy artillery batteries to the west of Beny, and "B" Company was assisted by the guns of HMCS "Algonquin", which destroyed a bunker of 105 mm guns. To their east, "C" and "D" Company of the North Shores advanced towards Tailleville—the headquarters of II Battalion of the 736th Grenadiers. Mortar fire north of the headquarters was both concentrated and accurate, slowing the advance of "C" Company. They were supported in their drive south by tanks of the Fort Garry Horse, which caught close to 100 German defenders in open fields. The North Shores and their armour support entered Tailleville at 14:00, at which point the six tanks of "C" Squadron moved through the village, destroying German gun emplacements. The defenders of the II Battalion had created a complex underground bunker system in the village, which enabled them to continuously outflank Canadian infantry; it took another seven hours to clear Tailleville of defenders, which ensured that the North Shores would be unable to capture German radar sites to the south on D-Day.
