10 June 1940, the Assietta division stayed on the border with France near mountain peaks Rochers Charniers, Grand Queyron, Mont Chaberton, the pass of Col de Montgenèvre, and valley. The advance on French territory started on 18 June 1940, with the border post captured by surprise. By 20 June 1940, the division moved past mountain crests, completing capture of the Mount Chenaillet and fortified area by 22-23 June 1940, but further advance was stopped by the Franco-Italian Armistice 25 June 1940.
