Napoleon inflicted further defeats on both Schwarzenberg's and Blücher's armies. Thus after six weeks fighting the Coalition armies had hardly gained any ground. The Coalition generals still hoped to bring Napoleon to battle against their combined forces. However, after the Battle of Arcis-sur-Aube on 20 March, where the Austrians outnumbered his dwindling army 80,000 to 28,000, Napoleon realised that he could no longer continue with his current strategy of defeating the Coalition armies in detail and decided to change his tactics. He had two options: he could fall back on Paris and hope that the Coalition members would come to terms, as capturing Paris with a French army under his command would be difficult and time-consuming; or he could copy the Russians and leave Paris to his enemies (as they had left Moscow to him two years earlier). He decided to move eastward to Saint-Dizier, rally what garrisons he could find, and raise the whole country against the invaders and attack their lines of communications.
