Yes quite a feat by the British Commander:

Venturer had only 8 torpedoes as opposed to U-864's 22, and so after 3 hours Launders decided to make a prediction of his opponent's zig-zag, and release a spread of his torpedoes into its predicted course. This manual computation of a firing solution against a three-dimensionally manoeuvring target was the first occasion on which techniques were used which became the basis of modern torpedo computer targeting computer systems.
The first torpedo was released at 12.12 and then at 17 second intervals after that (taking 4 minutes to reach their target), and Launders then dived suddenly to evade any retaliation from his opponent. U864 heard the torpedoes coming and also dived deeper and turned away to avoid them, managing to avoid the first three but unknowingly steering into the path of the fourth. Exploding, U864 split in two, was sunk with all hands and came to rest more than 150 m (500 ft) below the surface on the seafloor. Launders was granted a bar to his DSO for this action.
