Southend Patrol - Supermarine Spitfire
92 Squadron Supermarine Spitfires on an evening patrol.
Though most of the Battles of France and Britain were fought in daylight, RAF fighter alerts could start as early as 4am and carry all the way through to 11pm, accounting for the tiredness felt by all of the pilots involved.
Here Spitfires from 92 Squadron patrol along the Thames Estuary, a task they would have through the May and June period of 1940. After having a significant role in the battles over Dunkirk, the squadron would be moved to Pembrey for rest. They would return to 11 Group in September, based at Biggin Hill.
