The Battle of Waterloo was fought on Sunday 18 June 1815, near the town of Waterloo, in modern Belgium.  At the time, the area was part of the United Kingdom of the Netherlands.  The battle saw France’s Emperor Napoleon defeated by a multi-country alliance under the command of Britain’s Duke of Wellington, together with a Prussian army under Gebhard von Blucher. 

Wellington described the battle as "the nearest-run thing you ever saw in your life."
