war. During this period, Zubian and the rest of the Flotilla rotated through nighttime patrols of the Dover Strait in groups of four, supported by flotilla leaders; these patrols were intended to catch German torpedo boats that were conducting night bombardments of Allied positions in the Channel. While in the Dover Strait on 4 February 1918, she encountered the mine-laying U-boat , which was surfaced about off Zubians port bow with her radio antennae up. Zubian attempted to ram the submarine but the Germans managed to submerge. The destroyer then dropped depth charges over the submerged U-boat and a significant amount of oil and wreckage was observed thereafter. Zubian marked the location with a buoy and an hour later, the patrol vessel dropped additional depth charges there. Trawlers later located an object that divers confirmed was UC-50. Zubian also participated in the First Ostend Raid two months later on the night of 23–24 April. The attack was intended to close the German-held ports of Ostend and Zeebrugge, which were being used as bases for the U-boats. Zubian was assigned to the bombardment force, and along with the destroyers and , provided the close escort for a group of six monitors. The bombardment unit was covered by the Harwich Force in the Channel. The bombardment force was tasked with suppressing the German coastal defences, while a pair of old cruisers attempted to steam into the harbour entrances, where they would be sunk as blockships. The effort failed when both cruisers ran aground far outside of the harbour. Worn out by heavy wartime use, Zubian was sold in the immediate post-war draw down and broken up for scrap by December 1919.
