That day, Rosenberg's corps and Auffenberg's brigade marched from Disentis at dawn, heading west. The Austrians soon turned north to cross over the mountains and reach the Maderanertal, an alpine valley which led west to Amsteg. For the crossing, Auffenberg's brigade split into three separate columns, of which the middle one crossed the Chrüzli Pass. One battalion of the 109th Line defended the Oberalp Pass, with its main defense on the north side of the Oberalp Lake. Rosenberg sent the Mansurov Musketeers looping to the right. Miloradovich led the Kashkin Jägers to the left on a steep climb along the south side of the lake. Three regiments under Lieutenant General Maksim Vladimirovich Rehbinder made the main push in the center. Badly outnumbered, the French conducted a fighting retreat so that Rosenberg's troops did not reach Andermatt until the evening. The Russians claimed to have killed 180 Frenchmen and captured 41 at the cost of 150 killed and badly wounded. The 109th Line evacuated Andermatt and retreated southwest to Hospental.
