On 12 May 1940, she accidentally rammed and sank the Canadian which was acting as a boom defence vessel at Halifax, although without loss of life. For the remainder of her service in the war, whenever "Revenge" came to Halifax, the crews of other gate ships would make elaborate and exaggerated "Abandon Ship" manoeuvres in mockery. On 30 May, "Revenge" took part in Operation Fish, the removal of all of the United Kingdom's gold reserves to Canada, in case of invasion, leaving the River Clyde with £40 million worth of bullion on board, bound for Halifax. On 3 July 1940, while at Plymouth, boarding parties from "Revenge" took control of the and the large submarine-cruiser , in case their crews decided to return them to Vichy France where they might fall into the hands of the Germans. The first British sailor to board "Surcouf", Leading Seaman Albert Webb, was shot dead by a French officer, who was in turn shot dead by a British officer. On the following day, "Revenge" resumed Operation Fish, this time with a cargo worth £47 million, repeating this on 11 August with £14.5 million from Greenock.
