While the evacuation of troops at Dunkirk in June, 1940 brought most of the men home, it left ALL of its military equipment behind, which left the British army in a perilous state.  In late summer, the German Luftwaffe attacked, trying to destroy the Royal Air Force (RAF), which would leave Britain vulnerable to invasion, or at least open to negotiation.  The resulting Battle of Britain was narrowly won by the British through the foresight, planning, leadership, and steadfastness of Air Marshall Hugh Dowding and the tremendous bravery of the RAF pilots.  The best of the RAF squadrons was the Polish Kosciuszko Squadron.  The purpose of this course is to tell the fascinating story of how the British won the battle and the role of the Polish squadron.
