The catastrophe in Russia now emboldened anti-French sentiments throughout Europe. The Sixth Coalition was formed and Germany became the centrepiece of the upcoming campaign. With customary genius, Napoleon raised new armies and opened up the campaign with a series of victories at Lützen and Bautzen. But due to the poor quality of French troops and cavalry following the Russian campaign, along with miscalculations by certain subordinate marshals, these triumphs were not decisive enough to win the war and only secured an armistice. Napoleon hoped to use this respite to increase the quantity and improve the quality of the "Grande Armée", but when Austria joined the Allies, his strategic situation grew bleak. The campaign reopened in August with a significant French victory at the two-day Battle of Dresden. However, the adoption of the Trachenberg Plan by the Allies, which called for avoiding direct conflict with Napoleon and focusing on his subordinates, paid dividends as the French suffered defeats at Großbeeren, the Katzbach, Kulm, and Dennewitz. Growing Allied numbers eventually hemmed the French in at Leipzig, where the famous three-day Battle of the Nations witnessed a heavy loss for Napoleon when a bridge was prematurely destroyed, abandoning 30,000 French soldiers on the other side of the Elster River. The campaign, however, did end on a victorious note when the French destroyed an isolated Bavarian corps which was trying to block their retreat at Hanau.
