2005 Campanula approaching from eastward, fired one round
2006 U-boat observed submerging

2025 Altered course to pass over position of attack, no wreckage seen
20384 inch gun crew reported periscope, which subsequently proved to be a spar floating vertically. Altered course to attempt to ram.
2044 Turned to investigate wreckage which was gradually coming to the surface.
2049 Lowered seaboat to collect specimens of wreckage. Picked up human remains, German naval collar silk, lambs wool coats, cushion, grey chrome leather coat and naval buttons marked Schmidt, wood locker door and alley fittings.

Extract of Report from Captain (D) Liverpool to C in C Western Approaches 13 August 1941

The Enemy submarine attack by Hydrangea and Campanula is considered to be sunk by Hydrangea first attack as wreckage (spar) was seen before their second attack. The explosion two minutes after the first attack and the pieces of human flesh recovered indicate that ther explosion occurred inside the u-boat.

More evidence that HMS Hydrangea alone was responsible for the destruction of U-401.
