Some aspects of bearings taken by HMS Pelican during the key battle of the Atlantic,   May 1943  (pdf)(German language)
Bearings taken between 5/5/43 hour 0038 and 6/5/43 hour 2218.

German U-boats attacked convoy ONS 5 with 41 submarines. It looked firstly, that they again could win this battle as they sunk, within two days, 11 ships. However, within a few hours the Allies killed later 5 U-boats. This forced Dnitz (Doenitz) to withdraw this main submarine forces from Atlantic operations. From this point onwards, the great menace of the German U-boats was diminished. They never could really threaten Allied supply routes again.
