French troops concentrated in Paris had as many soldiers as the invaders and more cannons. There were two major skirmishes and a few minor ones near Paris during the first few days of July. In the first major skirmish, the Battle of Rocquencourt, on 1 July, French dragoons, supported by infantry and commanded by General Exelmans, destroyed a Prussian brigade of hussars under the command of Colonel von Sohr (who was severely wounded and taken prisoner during the skirmish), before retreating. In the second skirmish, on 3 July, General Dominique Vandamme (under Davout's command) was decisively defeated by General Graf von Zieten (under Blücher's command) at the Battle of Issy, forcing the French to retreat into Paris.
