Operation Torch and the cost of a narrow focus

The episode first separates headline submarine totals from operational availability: by 1945 Germany could count more than 400 boats, while only about 144, later 166, were operational. It then contrasts Dönitz's attention to merchant sinkings with the strategic requirement to ask why escort numbers had shifted. Despite having roughly 196 submarines in the Atlantic during Operation Torch, he did not recognize the scale or purpose of the Allied movement. The escorts were concentrated around the invasion force, leaving other shipping more exposed and creating opportunities for U-boat kills elsewhere. Those losses did not defeat the operation because the Allies were prepared to accept them if the landing force reached North Africa. This is presented as the difference between operating a weapon system efficiently and understanding the opponent's operational objective.
