In 1810-1812 Napoleon led a war against Russia, however things in the end did not end up at he expected. Out of the 600,000 troops who began the campaign, only an estimated 100,000 made it out of Russia. On April 6, 1814, Napoleon was forced to abdicate the throne. With the Treaty of Fontainebleau, he was exiled to Elba, a Mediterranean island off the coast of Italy. On February 26, 1815, Napoleon escaped Elba and sailed to France with a group of more than 1,000 supporters. On March 20, he returned to Paris, where he was welcomed by cheering crowds. The new king, Louis XVIII fled, and Napoleon began what came to be known as his Hundred Days campaign. However, upon Napoleon's return, many French enimies were preparing for war. On June 18, 1815, at the Battle of Waterloo, Napoleon's forces were defeated and he was forced to exile again at Saint Helena.
