"B" Company of the North Shore Regiment and No. 48 Commando of the Royal Marines were engaged in a protracted fight to secure Saint-Aubin and Lagrune-sur-Mer. "B" Company had generally neutralized the strongpoint WN27 within two hours of landing, which allowed Troops A and B of the Royal Marines to push east. These units had the important objective of bridging the gap between the landing zones at Juno and Sword, which would allow for a continuous Anglo-Canadian front by the end of the first day. The Royal Marines began to advance on Lagrune and strong-point WN26, while to their east No. 41 Commando Royal Marines advanced from Sword. The strongpoint was defended by "a reinforced platoon from the 736th Grenadiers" and was a group of fortified houses and 50 mm anti-tank guns. B Troop's first attempt to capture it failed and the assault was renewed with support from Centaur tanks only to again falter in the face of heavy resistance. No. 48 Commando was forced to call the assault off at nightfall, as reports of massing for counter-attacks by the 21st Panzer Division against the divide between Sword and Juno arrived. The strong points at Lagrune and Luc-sur-Mer were captured on 8 June.
