Heavy Anti Aircraft Guns
The backbone of the air defences of the Portsmouth area were the heavy anti-aircraft gun sites and associated search lights deployed to across the area. They were designed to engage with enemy aircraft approaching from any compass direction.

Three HAA gun batteries were assigned to Hayling Island in 1939, two deployed at Sinah and Northney respectively and one mobile battery to be deployed as required.
On the 17th April 1941 the Sinah gun site was hit by 30 enemy bombs resulting in the loss of 3 of its guns and the death of six gunners with thirty others injured. From this time, the gunners were mainly replaced by women of the ATS who were outstandingly successful for the remaining duration of the war.
