The debacle in Russia loosened the French grip on the German princes. In 1813, Napoleon mounted a campaign in the German states to bring them back into the French orbit; the subsequent War of Liberation culminated in the great Battle of Leipzig, also known as the Battle of Nations. In October 1813, more than 500,000 combatants engaged in ferocious fighting over three days, making it the largest European land battle of the 19th century. The engagement resulted in a decisive victory for the Coalition of Austria, Prussia, Russia, Saxony, and Sweden, and it ended French power east of the Rhine. Success encouraged the Coalition forces to pursue Napoleon across the Rhine; his army and his government collapsed, and the victorious Coalition incarcerated Napoleon on Elba. During the brief Napoleonic restoration known as the 100 Days of 1815, forces of the Seventh Coalition, including an Anglo-Allied army under the command of the Duke of Wellington and a Prussian army under the command of Gebhard von Blücher, were victorious at Waterloo (18 June 1815). The critical role played by Blücher's troops, especially after having to retreat from the field at Ligny the day before, helped to turn the tide of combat against the French. The Prussian cavalry pursued the defeated French in the evening of 18 June, sealing the allied victory. From the German perspective, the actions of Blücher's troops at Waterloo, and the combined efforts at Leipzig, offered a rallying point of pride and enthusiasm. This interpretation became a key building block of the "Borussian" myth expounded by the pro-Prussian nationalist historians later in the 19th century.
