“moved an entire panzer division - 90,000 soldiers - to Greece”
90k soldiers is not a division - it is an Army.
10,000 guys in tanks and 80,000 Remington Raiders.
According to Wikipedia, the Nazis moved two Panzer Divisions from the Eastern Front, which not available at the Battle of Kursk and one from France. If they added three Panzer divisions to Greece, no telling how many infantry they would have sent. Apparently “Mincemeat swallowed whole” is true.
Also, when the German subsequentially found genuine maps and documents, they regarded them as ruses as a result of Mincemeat.
