Nine neutral merchant ships were sunk. Only four officers and 41 men from Strongbow survived, while just eight of Mary Rose's roughly 80 men escaped; Strongbow's commander later died of pneumonia caused by the action. About 150 Scandinavian merchant sailors also died. Mary Rose transmitted one message, but it was not effectively received, and Brummer jammed further signals; Strongbow had sent no warning before being hit. British hunting groups learned what had happened only after the raiders were heading home. The later court-martial debate remains difficult to judge, and scattered postwar German reports suggest that some cruiser officers also wanted to leave mines in the next convoy's path.

Losses, jamming, and the delayed response
The raid sank neutral merchant ships and devastated both escorts, while disrupted signalling left British hunting forces too late to intercept.
