HMS Adventure, pennant number M23, was an Adventure-class minelaying cruiser of the Royal Navy built in the 1920s that saw service during the Second World War. Her commander between 1928 and 1929 was the future First Sea Lord John H. D. Cunningham. Laid down at Devonport in November 1922 and launched in June 1924, Adventure was the first vessel built for service as a minelayer; she was also the first warship to use diesel engines, which were used for cruising. Adventure first joined the Atlantic Fleet, then was transferred to the China Station in 1935. In World War II, the ship was damaged in 1941 and 1944, and was converted to a landing craft repair in 1944. In 1945 Adventure was reduced to reserve and in 1947 she was sold and broken up for scrap.

HMS Basilisk was a B-class destroyer built for the Royal Navy around 1930. Initially assigned to the Mediterranean Fleet, she was transferred to the Home Fleet in 1936. The ship escorted convoys and conducted anti-submarine patrols early in World War II before participating in the Norwegian Campaign. Basilisk was sunk by German aircraft during the Dunkirk evacuation in 1940.
