The day the war ended:
We shall go on to the end. We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.
– Winston Churchill, House of Commons, June 4, 1940.
On that day, Britain had already won World War 2.
All the rest, the five frothing, grisly years hence, was was merely filling in the morbid blanks, bloody frosting on a victory cake baked five long years heretofore.
