 Wainwright continued to operate out of Queenstown until June 1918 when she was reassigned to United States naval forces in France . On the 8th , she reported for duty at Brest , the French port from which she conducted her patrols for the remainder of the war . Those patrols brought no further encounters with the enemy . Only two events of note occurred between June and November 1918 . On the night of 19 / 20 October , she sighted what appeared to be a submarine running on the surface . However , upon closer inspection , the object proved to be a derelict carrying the crew of the 77 @-@ ton Portuguese schooner Aida , which had been captured by German submarine U @-@ 43 and sunk with explosive charges . Wainwright took on the survivors and saw them safely into port . Later , during the evening of 1 November , heavy winds at Brest caused the destroyer to drag anchor : and she struck the breakwater . After Jarvis had failed to pull her loose , the tug Concord took over and finally managed to refloat the warship at 19 : 20 and towed her into Brest .
