On 1 July 1815,
Napoleon's
Grande Armée fought its last battle in Rocquencourt and
Le Chesnay. After the defeat of
Waterloo on 18 June 1815,
Grouchy's army withdrew to
Paris via
Namur and
Dinant, reaching Paris on 29 June, a few days before the
Prussians, who camped at
Versailles. While negotiating the final
armistice,
Exelmans was ordered to attack the Prussians at Versailles on 1 July 1815. 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. They were forced into a small, narrow street in
Le Chesnay and killed or captured. However, the main body of the Prussian army succeeded in reaching Saint-Germain. (From Presentation of Rocquencourt.) ==Points of interest==
