One moonless night in May 1942, six British Commandos drove into Italian occupied Benghazi in a "battle waggon" painted to resemble a German staff car with a broad white stripe across the bonnet, the German air-recognition mark. But appearances were deceptive; it was filled with high explosives, along with two inflatable rafts, and mountings for two machine guns, which could be removed and hidden out of sight on the floor. Benghazi was in for some serious business. One of the commandos, in fact, was the son of the British Prime Minister, but it was under the command of Fitzroy Maclean, who soon faced his first crisis: a military check point.
