 Garrison Point Fort remained in service through the Second World War and was re-armed with two twin 6-pounder Quick Firing (QF) guns to defend against fast-moving attackers such as E-boats and destroyers.One of them was mounted on the fort's roof and the other was situated outside the front of the casemates.New gun emplacements, gun towers, a magazine and a searchlight emplacement were all constructed at this time.
