In 1943, during the Second World War the body of an English man, William Martin, was discovered off the Spanish coast. The papers he had been carrying were returned to England, where they were carefully examined. They had clearly been changed and that was exactly what the British had hoped would happen, for Martin was a trick designed to fool the Germans.

　 Martin did not exist. The body was that of a sailor who looked as though he had died when his boat sank, but in fact he had been ill and died. Leaving the boat to go down, his parents allowed the dead body to be put into the sea near Spain. It was hoped that the Germans would find it and read the fake(假的)papers he carried.

　　The papers said that the British would attack the island of Sardinia, when in fact they planned to attack the island of Sicily. The trick was successful. When the British landed on Sicily, most of the heavy German guns had been moved to defend(保卫) Sardinia.
