When the armed merchant cruiser was attacked and sunk defending her convoy on 23 November, Edinburgh was among the flotilla detached to search for the German commerce raider, the battleship , responsible. However, the search was unsuccessful, and Edinburgh returned to escort duties. On 18 March 1940, she arrived in the Tyne for a lengthy refit which lasted until 28 October.
