HMS "Colossus" was the lead ship of her class of two dreadnought battleships built for the Royal Navy at the end of the first decade of the 20th century. She spent her whole career assigned to the Home and Grand Fleets, often serving as a flagship. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during World War I generally consisted of routine patrols and training in the North Sea. "Colossus" was the only dreadnought from the main body of the Grand Fleet to be hit during the Battle of Jutland, although she suffered only minor damage. The ship was deemed obsolete after the war and was reduced to reserve and then became a training ship. "Colossus" was hulked in 1923 and sold for scrap in 1928.
