The history of the German U-Boat War of 1939 through 1945 has never before been told in any great depth for various reasons.  One reason of course, is that this data was not readily released to the general public during the war for reasons of security.  Learn more about this historic event at https://sharkhunters.com/books/ and for information about Sharkhunters, the official history of the U-Boats, go to https://sharkhunters.com/
There is a certain mystique about submarines in general and the U-Boats of Germany in World War Two in particular.  Never before in history has any nation built and fought such a massive numbers of submarines – Germany had many hundreds in their fleet and the men who rode these boats were a particularly unique kind of warrior.  I have been blessed to have known hundreds of the surviving U-Bootfahrer and dozens of the Skippers.  These were the most honorable of the combatants…..many of the photos you will see were given to Sharkhunters by these warriors.
