Clerfayt's army was deployed behind the steep-banked Roer with its left flank at Düren and its right flank at Roermond. However, the Austrian commander placed the bulk of his forces between Düren and Linnich, with an advanced west-bank position at Aldenhoven in front of his center at Jülich. The extreme right was in tenuous communication with the army of Prince Frederick, Duke of York and Albany near Grave. The positions around Aldenhoven were entrenched as were other portions of the line.
On 1 October 1794, General of Division Jourdan ordered Schérer and the Right Wing to seize Düren. In the center, Jourdan directed Jacques Maurice Hatry to take Altorp, Antoine Morlot and Jean Etienne Championnet to capture Aldenhoven and cross the river at Jülich, while François Joseph Lefebvre occupied Linnich. Meanwhile, Kléber and the Left Wing were instructed to move upstream from a position opposite Roermond and cross the Roer at Ratheim (near Hückelhoven). The Army of Sambre-et-Meuse numbered about 100,000 troops, the largest French army yet assembled in the war. The French were on the road on the morning of 2 October and only came into action near mid-day.
