The failure of Operation Pastorius led Hitler to rebuke Admiral Canaris and no sabotage attempt was ever made again in the United States. During the remaining years of the war, the Germans only once more dispatched agents to the United States by submarine. In November 1944, as part of Operation Elster a German submarine, U-1230, dropped two RSHA spies off the coast of Maine to gather intelligence on American manufacturing and technical progress.
