World War I: The first British Royal Navy defeat of the war with Germany, the Battle of Coronel, is fought off of the western coast of Chile, in the Pacific, with the loss of HMS Good Hope and HMS Monmouth.
The Battle of Coronel was a First World War Imperial German Navy victory over the Royal Navy on 1 November 1914, off the coast of central Chile near the city of Coronel. The East Asia Squadron (Ostasiengeschwader or Kreuzergeschwader) of the Kaiserliche Marine (Imperial German Navy) led by Vice-Admiral Graf Maximilian von Spee met and overpowered a British squadron commanded by Rear-Admiral Sir Christopher Cradock.
The engagement probably took place as a result of misunderstandings. Neither admiral expected to meet the other in full force. Once the two met, Cradock understood his orders were to fight to the end, despite the odds being heavily against him. Although Spee had an easy victory, destroying two enemy armoured cruisers for just three men injured, the engagement also cost him almost half his supply of ammunition, which was irreplaceable.
Shock at the British losses led the Admiralty to send more ships, including two modern battlecruisers, which in turn destroyed Spee and the majority of his squadron on 8 December at the Battle of the Falkland Islands.
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.
From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to refer to it as "the Royal Navy" without qualification. Following World War I, it was significantly reduced in size, although at the onset of World War II it was still the world's largest. During the Cold War, the Royal Navy transformed into a primarily anti-submarine force, hunting for Soviet submarines and mostly active in the GIUK gap. Following the collapse of the Soviet Union, its focus has returned to expeditionary operations around the world and it remains one of the world's foremost blue-water navies.The Royal Navy maintains a fleet of technologically sophisticated ships, submarines, and aircraft, including 2 aircraft carriers, 2 amphibious transport docks, 4 ballistic missile submarines (which maintain the nuclear deterrent), 6 nuclear fleet submarines, 6 guided missile destroyers, 12 frigates, 11 mine-countermeasure vessels and 26 patrol vessels. As of August 2021, there are 75 operational commissioned ships (including submarines as well as one historic ship, HMS Victory) in the Royal Navy, plus 11 ships of the Royal Fleet Auxiliary (RFA); there are also five Merchant Navy ships available to the RFA under a private finance initiative. The RFA replenishes Royal Navy warships at sea, and augments the Royal Navy's amphibious warfare capabilities through its three Bay-class landing ship vessels. It also works as a force multiplier for the Royal Navy, often doing patrols that frigates used to do.
The Royal Navy is part of Her Majesty's Naval Service, which also includes the Royal Marines. The professional head of the Naval Service is the First Sea Lord who is an admiral and member of the Defence Council of the United Kingdom. The Defence Council delegates management of the Naval Service to the Admiralty Board, chaired by the Secretary of State for Defence. The Royal Navy operates from three bases in Britain where commissioned ships and submarines are based: Portsmouth, Clyde and Devonport, the last being the largest operational naval base in Western Europe, as well as two naval air stations, RNAS Yeovilton and RNAS Culdrose where maritime aircraft are based.
