Lecourbe was in Altdorf at the northern end of the upper Reuss valley with the 720-man divisional reserve of nine grenadier companies. Molitor's brigade was far to the east near Glarus on the upper Linth River. The 67th Line defended the Gotthard Pass, the 109th Line held the Oberalp Pass and the village of Andermatt, and Loison's brigade was posted near Amsteg in the center of the upper Reuss valley.
