Italy declared war on France and Britain on the night of June 10, 1940.
Britain did not wait.
Within 24 hours, 36 RAF bombers lifted off from Yorkshire, refueled in the Channel Islands, and flew across the Alps in the dark to bomb Turin, the industrial heart of Italy.
Ten planes made it through. Turin became the first Italian city bombed in the entire war.
Mussolini had spent years building up Italy's image as a great power. He had calculated that joining Germany would cost him almost nothing.
The RAF sent their answer the very next night.
Most people know about Churchill's speeches. Fewer know that while he was giving them, his bombers were already over Italy.
