Following the signing of the Treaty of Versailles in 1919, Germany was not permitted to build or operate submarines. However clandestine training onboard Finnish and Spanish submarines took place and U-boats were still built to German designs in Dutch yards.
At the outset of the Second World War, Dönitz argued for a 300-strong U-boat fleet, since his force of 57 U-boats ‘could only inflict pin-pricks against British seaborne trade’. In August 1939, U-48 left Germany, commanded by ‘Vaddi’ Schultze, to take up a waiting position around England.
It scored its first success on 5 September, when it torpedoed the British freighter Royal Sceptre, then the Winkleigh on 8 September. On both occasions – the first of many – Schultze showed himself to be a notable he addressed signals to Churchill giving positions of the sinkings so that crews could be saved.
By 1 August 1941, U-48, the most successful boat of the Second World War, had sunk 56 merchant ships of 322,478 gross tons and one corvette. She was then transferred to the Baltic as a training boat. Schultze became commander of operation 3 U-Flotilla and later was appointed commander, II/Naval College Schleswig. He died in 1987 at the age of 78. U-48 was scuttled on 3 May 1945.
I always become a little worried when approaching a WW2 piece of non-fiction that focuses solely on things like planes, tanks, weopons, etc... or, like here, a U-Boat, in the fact that a lot of the time we get too much unnecessary details that just bore the reader. Thankfully here, while detailed it is, it never goes over the top. Franz Kurowski; who has apparently over 100 WW2 books to his name, fought with the Afrika korps as a luftwaffe paratrooper after being called up in 1942, and had been working as a journalist from the late 50s. Split up over 15 chapters, which go from the early development of U-48, to the battle of the Atlantic and the Biscay Front, through to the loss of the Bismarck, I came away thinking that Kurowski did more than enough to satisfy my general interest. It's worth noting of course, that even though this U-Boat did a hell of a lot of damage to allied efforts, it was only possible by having a top-notch crew and three of the best skippers - including one Herbert Schultze, commander on eight war patrols - to succeed in the way that it did. The book also comes with various b&w photos from above and below deck, as well as the action, like the sinking of torpedoed ships. 3.5 rounded up to 4.
