Note 249 — 597.

The Prussian army, entangled in the wood of Argonne between the Meuse and the Marne, were outgeneralled by Dumouriez and Kellerman. The Duke of Brunswick, after the battle of Valmy (September 20), opened negotiations with Dumouriez (September 22-28) at Ste. Menehould, and then (October 1) retreated across the French frontier. The Austrians failed to take Lille, and, at the approach of Dumouriez, retired into the Low Countries (October 8). Dumouriez, following them, won the battle of Jemappes (November 6), and overran Belgium. At the same time the French troops were masters of Savoy and Nice, and of the country between the Rhine and the Maine. Fox rejoiced at the flight of the invaders. "No public event, not excepting Saratoga and York Town, ever happened that gave me so much delight" (C. J. F. to Lord Holland, October 12, 1792).
