Based at Duxford, 19 Squadron were the first operational Spitfire squadron receiving their aircraft at the end of 1938. Forming part of Group 12 of Fighter Command, 19 Squadron saw much action during the Battle of Britain. They flew Spitfire up until 1944, when they converted to Mustangs to allow them to fly long-range escort duties.
303 Polish Squadron
One of 16 Polish squadrons to fly out of Britain during the war, 303 were made up of Polish pilots and ground crew. 303 were in fact the highest scoring squadron during the Battle of Britain, claiming 126 Luftwaffe aircraft. They converted from Hurricanes to Spitfires in 1941.
Initially based in Scotland, 603 Squadron were involved in shooting down the first German raider of the war when together with 602 Squadron, a number of Junkers Ju 88 bombers were intercepted over the Forth of Firth. Two were shot down, one was heavily damage while no RAF planes were lost.
603 moved to Southern England during the Battle of Britain where according to German records, they identified it as the highest scoring British squadron of the Battle of Britain. Later, 603 moved to Malta to help defend the small Mediterranean island.
