She participated in Operation Dynamo, the evacuation from Dunkirk in late May and early June 1940. Bismarck breakout In early May 1941, the British Admiralty was on the alert that the Bismarck might attempt to break out into the North Atlantic; so Icarus was ordered to Scapa Flow for possible deployment against the Germans. On 22 May, just after midnight, Icarus sailed along with the destroyers , , , , and , escorting the battlecruiser and the battleship to cover the northern approaches. The intention was that the force would refuel in Hvalfjord, Iceland, and then sail again to watch the Denmark Strait. On the evening of 23 May, the weather deteriorated. At 20:55 hrs., Admiral Lancelot Holland aboard Hood signalled the destroyers "If you are unable to maintain this speed I will have to go on without you. You should follow at your best speed." At 02:15 on the morning of 24 May, the destroyers were ordered to spread out at intervals to search to the north. At about 05:35, the German forces were sighted by Hood, and shortly after, the Germans sighted the British ships. Firing commenced at 05:52. At 06:01, Hood took a shell from Bismarck in the after magazine, which caused a massive explosion, sinking the ship within 2 minutes. Electra and the other destroyers were about away at the time. Upon hearing that Hood had sunk, Electra raced to the area, arriving about two hours after Hood went down. They were expecting to find many survivors, and rigged scrambling nets and heaving lines, and placed life belts on the deck where they could be quickly thrown in. From the 94 officers and 1,321 ratings aboard Hood, just three survivors were found. Electra rescued them, and continued searching. Shortly thereafter, Icarus and Anthony joined in the search, and the three ships searched the area for more survivors. No more were found, only driftwood, debris, and a desk drawer filled with documents. After several hours searching, they left the area.
