How Hitler Wasted Germany’s Deadliest Weapon - Nazi Rearmament 01 - U-Boat Type VIIC

Early in World War II, German U-boats came dangerously close to starving Britain into submission. The Type VII submarine - especially the VIIC—became the backbone of the Kriegsmarine’s Atlantic campaign, sinking thousands of Allied ships and threatening to win the Battle of the Atlantic. But despite its devastating effectiveness, the U-boat war ultimately failed—and not just because of Allied countermeasures. In this documentary, Spartacus Olsson breaks down how Adolf Hitler’s strategic miscalculations, competing naval doctrines, and direct interference undermined Germany’s most effective naval weapon. From the clandestine development of submarines after the Treaty of Versailles, through Admiral Karl Dönitz’s vision of a tonnage war, to the catastrophic losses of German submariners, this episode examines how Nazi rearmament translated into wartime reality - and failure.
