On 26 May, Xaintrailles' right column crossed the Saltina river via a ford and marched to Brig, where some of the insurgents had rallied. These abandoned the town and fled into the mountains behind it. The left column, column Xaintrailles, reached Naters on the right bank of the Rhône and proceeded to Mörel and Lax, seeking to capture the bridge between Lax and Ernen, where the largest group of the insurgents had congregated. While he was reforming his troops, he offered the insurgents an olive branch: if they would lay down their arms and return to their homes, he promised an amnesty for the past. Those who persisted in revolt would face summary execution. A number of the insurgents did submit, but many withdrew to Lax where, reinforced by a couple of Austrian battalions, they rejected all offers of amnesty and placed their reliance on nature's formidable position. There followed a day-long battle with alternating results; eventually, the insurgents were routed, but the contest was maintained by those two Austrian battalions, who eventually abandoned the field as night fell, and light failed. Xaintrailles pushed on with the grenadiers of the 100th and sent several companies of the 100th to St. Bernard. His Swiss allies guarded the gorges and defiles behind him. He established his headquarters at Brig, from which he could control the passes at Great St. Bernard and Simplon and access to northern Italy, and awaited his instructions from Massena.
