These were probably M 6041, M 6043, M 6044, M 6045, M 6046 and M 6047 escorting three lighters from Marseille to Toulon.

(All times are zone -1)
1224 hours - Sighted a vessel bearing 340°, close to the land. Altered course towards.

One of the torpedoes must have hit. Depth control was lost and Ultimatum started to descend. The remaining two torpedoes of the salvo were not fired.

1250 hours - Ultimatum came to rest on the bottom at 160 feet. Both motors were stopped, all machinery was stopped and the ship was shut off for depth charging. Many listening charges were dropped by the enemy for the next 7 hours but no depth charges were dropped during this period.

2230 hours - Started blowing main ballast.

2245 hours - Ultimatum came of the bottom.

(All times are zone -1)
0707 hours - Sighted a 500 tons U-boat bound for Toulon. Closed to attack.
