 Marlborough served with the Grand Fleet for the duration of the war , primarily patrolling the northern end of the North Sea to enforce the blockade of Germany . She saw action at the Battle of Jutland ( 31 May – 1 June 1916 ) , where she administered the coup de grâce to the badly damaged German cruiser SMS Wiesbaden . During the engagement , Wiesbaden hit Marlborough with a torpedo that eventually forced her to withdraw . The damage to Marlborough was repaired by early August , though the last two years of the war were uneventful , as the British and German fleets adopted more cautious strategies due to the threat of underwater weapons .
