On this day, 210 years ago, June 18, 1815 (May 12, 1815 in the lunar calendar), the Battle of Waterloo. The Battle of Waterloo, which broke out on June 18, 1815, was a famous battle in world military history. At the beginning of 1815, Napoleon learned on the island of Elba that the Anti-French League had almost split due to uneven distribution of the spoils at the Vienna Conference. He led his old troops to escape the island of Elba and return to Paris to regain the throne. The monarchs of Britain, Prussia, Austria, Russia and other countries stopped quarreling and formed the seventh anti-French alliance, gathering 700,000 troops and preparing to attack Paris separately. On June 18, Napoleon led more than 100,000 troops to the village of Waterloo, south of Brussels, Belgium, and encountered 60,000 troops led by British general Wellington in the Allied Forces. Napoleon judged that the weakness of the British position was in the middle. He decided to feint an attack on the right wing of the British army and focus on the middle section. At 11 a.m., the French army began to attack Fort Ukumun on the right wing of the British army, forming a confrontation. At one afternoon, just as Napoleon was about to use his main force to storm the middle position of the British army, he suddenly received news that the Prussian army assembled by Brucher was coming to assist the British army. Napoleon was forced to draw two cavalry divisions from the General Reserve to block the Prussian army. At the same time, Grusch, who was originally responsible for pursuing the Prussian army, was quickly ordered to immediately return to support Waterloo while attacking the middle section. The British army resisted tenaciously and both sides suffered heavy casualties. At 6 p.m., Napoleon occupied the village of Saint-Laé in the middle. Due to the extremely fierce battle, the British army began to be unable to support it, and the French army could not expand its results. Both sides were waiting for reinforcements. In the end, the British army hoped for 30,000 reinforcements from Blucher, but the French reinforcements did not arrive. So the situation took a sharp turn, and Napoleon was attacked from both sides and was finally defeated. In this battle, the French army lost 32,000 people and the allied forces lost 23,000 people. After the Battle of Waterloo, the coalition forces quickly captured Paris, and Napoleon abdicated again and was exiled to St. Helena in the Atlantic.
