The Battle of Rocquencourt was a cavalry skirmish fought on 1 July 1815 in and around the villages of Rocquencourt and Le Chesnay. French dragoons supported by infantry and commanded by General Exelmans destroyed a Prussian brigade of hussars under the command of Lieutenant Colonel Eston von Sohr (who was severely wounded and taken prisoner during the skirmish). Prussian cavalry detachments under the command of Lieutenant Colonel Sohr ventured too far in advance of the main body of the Prussian army with the intention of reaching the Orléans road from Paris; where his detachment was to interrupt traffic on the road, and increase the confusion already produced in that quarter by the fugitives from the capital. However, when the Prussian detachment was in the vicinity of Rocquencourt, it was ambushed by a superior French force. Under attack, the Prussians retreated from Versailles and headed east, but were blocked by the French at Vélizy. They failed to re-enter Versailles and headed for Saint-Germain-en-Laye. Their first squadron came under fire at the entrance of Rocquencourt and attempted to escape through the fields.
