The Royal Navy suffers a major defeat against German battleships in the Battle of Coronel in November 1914.
A Royal Navy force under Vice Admiral Sir Christopher Craddock was sent to find a German naval squadron under Admiral Maximillian von Spree off the coast of Chile. Craddock's ships were mostly old and had smaller guns than the German ships, which meant they couldn't fire as far and had to get closer to be in range. Two of the British ships were sunk and the other two had to escape after dark.
The Battle of Coronel was a terrible defeat for the British Royal Navy, which was supposed to be the best in the world.
