UC-25 torpedoed Dartmouth so severely that her crew initially abandoned the cruiser as doomed. Dartmouth remained afloat, allowing a rescue party to reboard and bring her toward safety. The French destroyer Boutefeu then struck a mine laid by the same submarine while assisting the operation. Dartmouth's survival showed effective British damage control, while Boutefeu's loss demonstrated how one minelaying submarine could threaten both its target and the ships sent to help.
