Battle of the Falkland Islands
This was Britain's first naval defeat since the Battle of Lake Champlain in the War of 1812 and the first of a British naval squadron since the Battle of Grand Port in 1810. Once news of the defeat reached the Admiralty, a new naval force was assembled under Vice-Admiral Doveton Sturdee, including the battlecruisers and her sister-ship . This found and destroyed Spee's force at the Battle of the Falkland Islands.
