Snowfall stopped all operations until 27 September, when Le Doyen advanced up the Maurienne. On 29 September, Le Doyen's troops captured the southern exit of the Col de la Madeleine, cutting communications between Montferrat and Cordon. Kellermann's left column captured Beaufort on 28 September. The following day, Chef de brigade Jacques-Antoine de Chambarlhac de Laubespin seized the Cormet de Roselend, putting the French in a position to move south into the Tarentaise. Kellermann planned to attack Montferrat on 2 October, with the main column marching up the Tartenaise toward Moûtiers, Le Doyen coming across the Col de la Madeleine from the southeast, and Chambarlhac moving from Beaufort in the north. Seeing the trap prepared for his soldiers, Montferrat retreated up the valley. On 3 October, Kellermann pushed the last elements of Montferrat's column up the Little St Bernard Pass and the Tarentaise was clear.
