The day after the explosion, "Organisation Todt" workers were assigned to clean up the debris and wreckage. On 30 March at 16:30 the torpedoes from "MTB 74", which were on a delayed fuse setting, exploded at the old entrance into the basin. This raised alarms among the Germans. The "Organisation Todt" workers ran away from the dock area. German guards, mistaking their khaki uniforms for British uniforms, opened fire, killing some of them. The Germans also thought that some commandos were still hiding in the town, and made a street by street search, during which some townspeople were also killed.
