HMS Cossack was a Tribal-class destroyer of the Royal Navy, launched in 1907 and decommissioned in 1919. Built by Cammell Laird, she was part of the initial batch of five Tribal-class destroyers ordered under the 1905–06 shipbuilding program. Her design featured a length suitable for high-speed operations, powered by steam turbines rated at 14,000 shaft horsepower, fed by five boilers. She was equipped with three propeller shafts and distinguished by her three large funnels. Her armament initially consisted of three 12-pounder (3-inch, 76 mm) guns—two positioned side by side on the forecastle and one aft—and two 18-inch torpedo tubes. In 1909, her armament was increased with an additional two 12-pounder guns, enhancing her firepower. She achieved a trial speed of 34.619 knots, slightly exceeding her design requirement of 33 knots. Cossack's service history included assignments with the First Destroyer Flotilla of the Home Fleet, later transferring to the 4th and then the 6th Destroyer Flotilla by 1914. During World War I, she operated primarily in the North Sea and English Channel, taking part in patrols, shore bombardments, and convoy escort duties. Notably, she supported Belgian forces during the Battle of the Yser in October 1914 and was involved in defending against German torpedo boat raids in 1916. Her wartime service was marked by several incidents, including a collision with her sister ship Ghurka in August 1914 and another with the transport SS The Duchess in July 1917, which resulted in her stern being blown off and her being towed for repairs. In September 1918, she participated in the sinking of the monitor HMS Glatton to prevent a magazine explosion after a fire outbreak. After the war, HMS Cossack was sold for scrap in December 1919 to Thos. W. Ward. Her career exemplifies the adaptability and active engagement of early 20th-century destroyers in wartime naval operations, particularly in patrol, escort, and fleet support roles during the First World War.
