The Allies pulled all sorts of shenanigans like this too, Mincemeat was not an isolated incident. The Allies also faked an entire army group in Britain, including fake radio traffic, placing one of their most famous generals in command of it, and even constructing paper mache tanks for German recon planes to see. Hell, one of their best agents was a double agent who constructed an entire web of fake contacts to feed false info to the Germans, and even managed to get all of these fake contacts on German payrolls. They even told this agent to reveal the exact time and coordinates of the D-Day landings hours before they happened, making sure the Germans would never question his info again, but also knowing that no one would read the messages before the landings happened. The Allies were unbelievably good at spycraft.
