What could have happened if operation mincemeat had failed?

The Salerno invasion would not have occurred.

Explanation:

British Navy Lieutenant William Martin was traveling from London to North Africa in 1943 when his plane crashed offshore near the Spanish coast. He carried a delicate correspondence: the place where the Allies would invade southern Europe.

Within days, the documents were in the hands of the Germans. The corpse was returned with all his belongings, including the letter that said the destination of the invasion was Greece. The Germans reinforced the defenses in the country and continued to believe that this would be the landing site, even when Allied troops began to appear in Sicily.

Martin, of course, was a lie. It was a character invented by British intelligence in Operation Mincemeat: the body was from Glyndwr Michael, a boy who died poisoned in England.

If this operation had not been successful Salerno's invasion would not have occurred.
