HMS Cossack was a Tribal-class destroyer named after the Cossack people of the Russian and Ukrainian steppe. She became famous for the boarding of the German supply ship Altmark in Norwegian waters, and the associated rescue of sailors originally captured by the Admiral Graf Spee. She was torpedoed by U-563 and sank on 27 October 1941.

Construction and career

She was laid down at the Walker Naval Yard of Vickers-Armstrongs in Newcastle upon Tyne on 9 June 1936, launched on 8 June 1937 by Mrs. S. V. Goodall, commissioned on 7 June 1938 and completed on 14 June 1938. During her trials Cossack made 36.223 knots (67.085 km/h; 41.685 mph) at 366.4 RPM with 44,430 shp (33,130 kW) at 2,030 long tons (2,060 t).

Altmark incident

Cossack's first action was on 16 February 1940, under the command of Philip Vian. This was the Altmark Incident in Jøssingfjord, Norway which resulted in the freeing of the Admiral Graf Spee's prisoners who were being held aboard the supply ship Altmark and the death of seven crew members of the German ship. Cossack arrived at Leith on 17 February with the 299 freed prisoners. The Norwegian Government subsequently protested at Cossack's breach of Norway's neutrality and demanded the return of the prisoners (the same that the Norwegian Navy pronounced as non-existent), with the German government further protesting at the act of violence committed against Altmark.

Second Battle of Narvik

Cossack participated in the Second Battle of Narvik in April 1940. Later that year, she was part of the force which was assigned to hunt for a German surface raider that had been reported breaking out into the North Atlantic. The force consisted of the battlecruiser Hood, the light cruiser Edinburgh, and the destroyers Electra, Echo, Escapade, and Cossack. The report turned out to be false, so after spending a week at sea, including Christmas Day, she returned to port on New Years Eve.

Chasing Bismarck

In May 1941, she participated in the pursuit and destruction of the German battleship Bismarck. While escorting Convoy WS-8B to the Middle East, Cossack and four other destroyers broke off on 26 May, and headed towards the area where Bismarck had been reported. They found Bismarck that evening and made several torpedo attacks in the evening and into the next morning. No hits were scored, but they kept the Bismarck's gunners from getting any sleep, making it easier for the battleships to attack the Bismarck the next morning.

Loss

On 23 October 1941, Cossack was escorting a convoy from Gibraltar to the United Kingdom when she was struck by a single torpedo fired by the German submarine U-563 commanded by Klaus Bargsten. She was taken in tow by a tug from Gibraltar on 25 October, but the weather worsened and the tow was slipped on 26 October. Cossack sank in the Atlantic west of Gibraltar on 27 October 1941. 159 of her crew were lost.
