Lest we forget. The day after 15 Sept 1940 the skies were quiet.
15 Sept 1940 was a day of heavy and sustained fighting and the Germans suffered their highest losses since 18 August. It was obvious to both sides that German tactics had failed and the Luftwaffe had not gained the air supremacy they needed for an invasion. Fighting continued for another few weeks, but the action on 15 September was seen as an overwhelming and decisive defeat for the Luftwaffe.
For this reason, this date is celebrated in the United Kingdom as Battle of Britain Day.
RIP, all who gave their lives in The most decisive battle of the 20C
