Le Chesnay (in French pronounced as /lə ʃɛnɛ/) is a former commune in the Yvelines department in the Île-de-France region in north-central France. On 1 January 2019, it was merged into the new commune Le Chesnay-Rocquencourt.[2] It is located in the western suburbs of Paris, 16.7km (10.4miles) from the center of Paris.
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)
