Nevertheless, pre-dreadnoughts continued in active service and saw significant combat use even when obsolete. Dreadnoughts and battlecruisers were believed vital for the decisive naval battles which at the time all nations expected, hence they were jealously guarded against the risk of damage by mines or submarine attack, and kept close to home as much as possible. The obsolescence and consequent expendability of the pre-dreadnoughts meant that they could be deployed into more dangerous situations and more far-flung areas. World War I During World War I, a large number of pre-dreadnoughts remained in service. The advances in machinery and armament meant that a pre-dreadnought was not necessarily the equal of even a modern armoured cruiser, and was totally outclassed by a modern dreadnought battleship or battlecruiser. Nevertheless, the pre-dreadnought played a major role in the war. This was first illustrated in the skirmishes between British and German navies around South America in 1914. While two German cruisers menaced British shipping, the Admiralty insisted that no battlecruisers could be spared from the main fleet and sent to the other side of the world to deal with them. Instead the British dispatched a pre-dreadnought of 1896 vintage, . Intended to stiffen the British cruisers in the area, in fact her slow speed meant that she was left behind at the disastrous Battle of Coronel. Canopus redeemed herself at the Battle of the Falkland Islands, but only when grounded to act as a harbour-defence vessel; she fired at extreme range () on the German cruiser , and while the only hit was from an inert practice shell which had been left loaded from the previous night (the 'live' shells of the salvo broke up on contact with water; one inert shell ricocheted into one of Gneisenaus funnels), this certainly deterred Gneisenau. The subsequent battle was decided by the two s which had been dispatched after Coronel. This appears to have been the only meaningful engagement of an enemy ship by a British pre-dreadnought. In the Black Sea five Russian pre-dreadnoughts saw brief action against the Ottoman battlecruiser Yavuz during the Battle of Cape Sarych in November 1914. The principle that disposable pre-dreadnoughts could be used where no modern ship could be risked was affirmed by British, French and German navies in subsidiary theatres of war. The German navy used its pre-dreadnoughts frequently in the Baltic campaign. However, the largest number of pre-dreadnoughts was engaged
