Operation Mincemeat was a successful British disinformation plan during World War II. As part of Operation Barclay, the widespread deception intended to cover the invasion of Italy from North Africa, Mincemeat helped to convince the German high command that the Allies planned to invade Greece and Sardinia in 1943 instead of Sicily, the actual objective. This was accomplished by persuading the Germans that they had, by accident, intercepted "top secret" documents giving details of Allied war plans. The documents were attached to a corpse deliberately left to wash up on a beach in Punta Umbría in Spain. The operation started with the planting of false documents but the use of the Enigma machine helped double agents work for the Allies. In addition to technology, the use of double agents like Garbo was integral to Allied success in World War II.
