 In the last week of August, another naval operation commenced, this time called Operation "Assault", during which the cruiser HMS "Bellona" patrolled along the Biscay coast from Belle Isle near Lorient to Arcachon Point, south-west of Bordeaux.Continuing these sweeps through the remainder of the month, the Royal Navy and the Royal Canadian Navy patrolled off the coast.They sent landing parties ashore on the French mainland and outlying islands to secure them and ensured they were eliminated as potential bases of logistical supply to the Germans.
