Winston Churchill had a great number of massively memorable quotes. While not all of them were originally his, he made them memorable:
“We shall not flag or fail. We shall go on to the end. We shall fight in France, we shall fight on the seas and the 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.”
It has been reported that immediately after giving the speech, Churchill whispered to a colleague “And we’ll fight them with the butt ends of broken beer bottles because that’s bloody well all we’ve got.”
Never give up. You fight until you run out of room, but not out of “fight”. Someone may arrive at the last minute, or maybe you can trick the enemy into doing something stupid. Churchill bombed Berlin, which got the madman to change his bombing tactics. Prior to that, the Germans were bombing factories and airfields. British planes would take off, shoot down some German planes, and find there was no place to land because the Germans blew up the runways. Britain was running out of planes. When Goering started bombing London, he left the airstrips and factories alone. Hard of civilians, but it allowed the military to catch their breaths and rearm.
