Naval historian Stephen Prince talks to award-winning author Roger Moorhouse about his latest book, Wolfpack. Together, they will examine the Battle of the Atlantic through the lens of the German U-boat campaign that threatened Britain’s survival, and how the Allies ultimately overcame the U-boat menace and secured the sea lanes that kept the war effort alive. Germany’s U-boat crews suffered the highest per-capita losses of any arm of service in the war—around 30,000 dead, more than 75% of those who served—most with no grave but the sea. Moorhouse will tell us how, drawing on archival records, war diaries, and memory testimony, he pieced together the human stories while charting the strategic countermeasures that turned the tide.
