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 Imperial German Navy (Kaiserliche Marine) 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.
At the outbreak of war the Royal Navy and the Royal Australian Navy, with assistance from New Zealand and Japanese naval and land forces in the Far East, had captured the German colonies of Kaiser-Wilhelmsland, Yap, Nauru, and Samoa, instead of searching for the German East Asia Squadron commanded by Vice-Admiral Maximilian von Spee, which had abandoned its base at the German concession at Tsingtao in the expectation of war breaking out with Japan. The East Asia Squadron rendezvoused at Pagan Island in the Marianas in early August 1914. Eventually, recognising the German squadron's potential for disrupting trade in the Pacific, the British Admiralty decided to destroy it and searched the western Pacific Ocean after the East Asia Squadron had conducted the Bombardment of Papeete (22 September 1914), where a French steamer reported its presence.
On 4 October 1914, the British learned from an intercepted radio message that Spee planned to attack shipping on the trade routes along the west coast of South America.
