81 Years ago the Royal Air Force fought and won a strategically important battle that meant the UK stayed in the war and could assure ultimate victory. If we had been invaded or been forced to sue for peace, Germany would likely have prevailed and ruled from the Atlantic to Siberia. We'll never know of course but the consequences of losing the battle are much clearer, and make the suffering and setbacks that followed before victory happened pale in comparison.
Happy Battle of Britain Day Royal Air Force!
