Mussolini came in with Hitler’s reluctant permission. The Fuehrer was confident that, whatever mischief Il Duce could perpetrate, it would not materially affect the outcome. He recalled an impudent quip of World War I attributed to General von Falkenhayn. When, in 1915, the Kaiser was told that Italy planned to switch sides, von Falkenhayn assured the sovereign that it would not make any difference. “You see, your Majesty,” he said, “if they’re against us, we need ten divisions to beat them. If they’re on our side, we’ll still need ten divisions to help them.” Sure enough, by the following spring Mussolini came to regard every day, when nothing unpleasant befell his forces, as a day won. May 24, 1941, appeared to be such a day. On the Pincio, the trees abandoned themselves to the balmy caresses of a glorious Roman spring. On the elegant Via Condotti, the smart ladies of Roman society paraded; nothing in their finery betrayed the austerity of a country at war. But on that day a seemingly insignificant event occurred which was destined to have a special impact on the future of Mussolini’s Italy.
