HMS 
              Hermes (D 95) was built by Armstrong (Newcastle-on-Tyne), laid down 
              15th January 1918, launched 11th September 1919 and commissioned 
              7th July 1923. She was sunk by Japanese aircraft, off Ceylon, 9th 
              April 1942.
            HMS 
              Hermes was the first purpose-designed aircraft carrier built for 
              the Royal Navy and fitted with an off-centre island containing the 
              funnel and operations spaces. Although very narrow, the island was 
              quite long and massive for a ship this size. The island located 
              forward of amidships made the ship trim by the bow, the weight of 
              the off-set island also caused a list to starboard. This imbalance 
              had to be corrected by carrying more water ballast and fuel oil 
              in the port side and aft tanks than in the starboard side and forward 
              tanks. It was a time of trial and error. The basic hull had been 
              built along the lines of a light cruiser. 
             From 
              1920 until 1938 Hermes served mainly on the China Station. During 
              1928 and again in 1934 she received refits at Chatham. 
            During 
              World War II she served briefly with the Home Fleet before being 
              assigned to the southern Atlantic from October 1939. She worked 
              with the French navy based at Dakar until the Vichy government came 
              to power, following that her aircraft took part in a strike against 
              the French vessels at Dakar. In July 1940 she collided with a merchant 
              vessel and was repaired at Simonstown, South Africa. Following repairs 
              she continued patrols but this time in the Indian Ocean as part 
              of the Eastern Fleet.
            During 
              the Indian Ocean raid, Hermes was in harbour at Trincomalee, Ceylon, 
              undergoing repairs. Advance warning of a Japanese air raid allowed 
              her to leave port, but as she returned following the raid on April 
              9, 1942, she was spotted off Batticaloa by a Japanese reconnaissance 
              plane. Lacking planes of her own, she was defenceless when she was 
              attacked by 70 Japanese bombers. Hit 40 times, Hermes sank with 
              the loss of 307 men. 
            Her 
              escorts — the destroyer HMAS Vampire and the corvette Hollyhock 
              — and two tankers were also sunk. 590 survivors of the attack 
              were picked up by the hospital ship Vita and taken to Colombo. Some 
              survivors were taken to Kandy where they spent 10 days recuperating 
              at the Queens Hotel.
