U-Boat Ace Hans Rose

Hans Rose was one of Germany’s most successful WWI U-boat aces, and her most successful ace during the convoy period when attacks by U-boats were most difficult and dangerous. Acknowledging his chivalry, Admiral Sims USN declared ‘Allied naval officers would be willing today to shake [his] hand.’This book is the only time the Rose family has agreed to make Hans Rose’s personal papers available to any researcher or biographer. The authors present new information from the Krupp archives and naval archives in Britain, US, and Germany.
