The Sixth Coalition finally combined Russia, Prussia, Austria, Sweden and British finance into a single effort, and its armies had by now learned from France itself. At Leipzig in October 1813 their converging forces outnumbered Napoleon and, crucially, refused to dissolve after local setbacks, while several German allies defected in the middle of the battle. The French retreat that followed ended the satellite system east of the Rhine. In 1814 coalition troops entered Paris, and Napoleon abdicated once his own marshals refused to fight on.
