Guest Roger Moorhouse and host Iain Ballantyne discuss the German submarine threat in WW2 in a lively and engrossing chat. Roger is the author of several acclaimed books, including ‘Killing Hitler’ and ‘First to Fight’ and now ‘Wolfpack’, an excellent single volume deep dive into the submarine arm of the Kriegsmarine - Hitler’s navy - and which was reviewed in the November 2025 edition of Warships IFR.

Topics touched on in this episode include pondering why the Germans placed their bets on the U-boat again, for the second time in a quarter of a century, despite having seen a similar strategy fail in WW1.

Also discussed is the quality and character of the U-boat captains – cool, leather jacket, lumber jack shirt-wearing heroes or villains? Nazis to a man and fanatical supporters of the regime, of just Good Germans doing their best for their country?

Iain asks Roger if ‘the U-boat peril’ truly was the only thing that ever really frightened Winston Churchill in WW2 - or was the wartime British Prime Minister deploying his usual emotive characterisation to frame his own later record more valiantly?

The term Wolfpack reeks of lethality, provoking a shiver of fear, but how effective were the U-boats really once the Allies improved tactics, weaponry and training? Roger provides his perspective on that topic in addition to considering the strategies of Karl Dönitz, the U-boat force boss.

Looking at the moral dimension of the conflict, Roger and Iain ponder whether of not it is possible  to set aside the horror of the Nazis and what they did and feel empathy for the tens of thousands of young men in German submarines who died under a hail of Allied depth charges, bombs and gunfire. 

Both host and guest offer a dose of common sense about the fantasy in some quarters of Hitler escaping in a U-boat to live out the rest of his days in South America. Finally, Iain asks Roger what he feels might be lessons for today in dealing with the Russian threat, which includes submarines.
