HMS Chester was a Town-class light cruiser of the Royal Navy, belonging to the Birkenhead subtype, and was originally ordered for the Greek Navy in 1914 under the name Lambros Katsonis. Constructed by Cammell Laird, her keel was laid on October 7, 1914, and she was launched on December 8, 1915. She entered active service in May 1916, just weeks before the Battle of Jutland. Designated based on the Birmingham subclass but with notable differences, Chester’s armament was tailored to Greek specifications. She was fitted with ten BL 5.5-inch (140 mm) Mk I guns, an increase from the nine carried by her British counterparts, due to the lighter weight of the guns and the ability to fire an 85-pound shell at a higher rate of fire. Her secondary armament initially included two 12-pounder anti-aircraft guns, but these were replaced by a pair of 3-pounder guns on high-angle mounts due to developmental delays. Her propulsion system consisted of twelve Yarrow boilers feeding Parsons steam turbines, which drove four propeller shafts, producing 31,000 shaft horsepower aimed at achieving a speed of 26.5 knots. She measured 456 feet 6 inches in length, with a beam of nearly 50 feet, a draught of 15 feet 3 inches, and displaced approximately 5,185 long tons normally, increasing to 5,795 long tons at full load. During her service, HMS Chester participated in the Battle of Jutland as part of the 3rd Battle Cruiser Squadron. She endured intense German fire, receiving hits from 17 shells and suffering 29 fatalities, including the young Midshipman John ‘Jack’ Cornwell, who was posthumously awarded the Victoria Cross. Chester’s crew suffered casualties, with many wounded losing legs due to inadequate protective gun-shields. After the war, she served with the 3rd Light Cruiser Squadron until being placed in reserve. She was sold for scrapping in 1921, marking the end of her relatively brief but notable service. Her gun used by Cornwell is preserved in the Imperial War Museum, and her legacy includes Mount Chester in the Canadian Rockies, named in her honor.
