Action off Lerwick The Action off Lerwick was a small naval battle of 1917 fought in the North Sea during the First World War . Two German light cruisers attacked a convoy of coal - carrying ships and their escort . In the course of the battle , the two escorting destroyers and nine neutral Scandinavian ships were sunk off Shetland , Scotland . Background . The British regularly shipped coal across the North Sea from Norway in 1917 ; these convoys were lightly defended so the " Kaiserliche Marine " took advantage of the situation . At first , submarines were deployed to sink the merchantmen , but after these attacks failed the German Admiral Reinhard Scheer ordered an attack with surface combatants . U - boat s informed Admiral Scheer that a fleet of nine Scandinavian , one Belgian and two British steamers laden with coal were headed west from Lerwick . The two light cruiser s and — each armed with four naval gun s and two anti - aircraft gun s — were designated to ambush to convoy which was found on 17 October , off Lerwick . Over 600 officers and men made up the crews of the two warships . Escorting the convoy was two British destroyer s , and with two naval trawler s , and . The destroyers had complements of about 80 men and armament of three guns , three 2 - pounders and two torpedo tube s . British Lieutenant Commander Charles Fox led the Allies convoy in his flagship " Mary Rose " , Lieutenant Commander Edward Brooke skippered " Strongbow " . Action . At about 06 : 00 , lookouts on " Strongbow " spotted the two German light cruisers approaching their ship at a distance of over away . They were mistaken for British cruisers and signaled to identify themselves but no response was received . The Germans mistook the destroyers for cruisers themselves , and they began signaling the British to come out and fight . Eventually the range closed to within so the German ships opened fire with their 5 . 9 - inch guns . Immediately after , the two destroyers turned for an attack and opened up with their 4 - inch guns , followed by " Elise " while " P . Fannon " was ordered to continue west with the convoy . HMS " Strongbow " was struck first , shells damaged her main steam pipe and others knocked out her radio communications just as the radioman was attempting to raise the alarm . After a few more minutes of firing , " Strongbow " was heavily damaged so the Germans turned their attention to " Mary Rose " and quickly sank her . The Germans then opened fire on " Longbow " again and damaged her further while " Elise " was maneuvering to rescue " Longbow " ′ s crew . " Elise " opened fire and her shots missed but she drew German fire which was now being concentrated on the merchant ships . Both of the light cruisers fired on " Elise " and forced her to flee out of range . The convoy was then attacked again and all nine of the Scandinavian vessels were sunk . All together , about 250 Allies and Scandinavians were killed , at least 50 others were wounded . Lieutenant Commander Fox was killed along with about 70 others from " Mary Rose " , only two officers and eight enlisted men survived . " Strongbow " lost half of her complement , four officers and 44 men were rescued , she sank hours later at around 09 : 30 . German forces were accused of shelling survivors in the water but they later denied the accusation . Aftermath . When the action was over the German ships returned to base without damage or loss of life . Other British naval forces in the area did not receive news of the engagement until almost 16 : 00 , so " Brummer " and " Bremse " could not be intercepted . The event was regarded as an outrage by the Allies who protested that the attack on neutral ships was illegal and that the Germans gave the crews of the merchant vessels no time to evacuate , thus resulting in a large loss of civilian lives . Both of the British destroyer commanders received credit for bravery though some members of the Admiralty felt that by leaving the convoy to engage a superior enemy force , left the merchant steamers open for attack .
