The story of the HMS Venturer is remarkable. It was the first submarine in history to sink another submarine while both were submerged. Using its sonar cleverly, the Venturer was able to track and then torpedo the German U - 864. This was a great achievement in submarine warfare technology and tactics.
Well, the German U - 99 under Otto Kretschmer is a well - known story. Kretschmer was one of the most successful U - boat commanders. He sank a large number of Allied ships. His tactics were highly effective. He would often surface his U - boat to use his deck gun to finish off damaged ships, which was a very bold move considering the risks of being spotted by Allied aircraft or other ships.
Sure. The story of the USS Wahoo is quite famous. It was a very aggressive submarine under the command of Dudley 'Mush' Morton. The Wahoo carried out numerous daring attacks on Japanese shipping lanes. It was known for its fearless approach and its ability to strike quickly and then disappear into the depths. Sadly, it was eventually lost in action.
