"Bruce" was still part of the 10th Flotilla at the end of the war, and on 20 and 22 November, helped to escort German submarines that were surrendering under the terms of the Armistice of 11 November 1918 into Harwich. The Grand Fleet was broken up after the end of the war, with new destroyer flotillas formed, and by March 1919, "Bruce" was listed as leader of the newly established 7th Destroyer Flotilla, a reserve formation based at Rosyth. By December 1919, "Bruce" was serving as leader and Captain (D)'s flagship for the 4th Destroyer Flotilla, part of the Atlantic Fleet, and she remained part of the 4th Flotilla in January 1921. On 5 October 1921, "Bruce" was involved in a minor collision with the destroyer "Vendetta", and by the end of the year was again laid-up in reserve at Rosyth with a reduced complement as part of the 9th Destroyer Flotilla. From October 1922, "Bruce" was part of the 8th Destroyer Flotilla, but on 3 September 1924, returned to full active commission in the 1st Destroyer Flotilla as a temporary replacement for the leader , reducing back to a reduced (2/5) complement with the 8th Flotilla on 20 November that year.
