[1] The combat at Chashniki was conducted chiefly by Wittgenstein's advance guard, 11,000 troops led by General Yashvil, and the II Corps on the French side.

Second, Victor's new position at Senno was only 30 miles from Napoleon's intended line of retreat from Moscow, putting the Grande Armée within Wittgenstein's attacking range.

[5] Further, Wittgenstein's success increased the possibility that he could unite his command with the armies of Pavel Chichagov and Kutuzov, trapping the Grande Armée between three separate Russian forces.

Also, as a result of his victories at Polotsk and Chashniki, Wittgenstein dispatched a force under General Harpe to capture the massive French supply depot at Vitebsk.

On 7 November, after a short combat, the French garrison at Vitebsk surrendered to Harpe, and huge caches of foodstuffs and war material fell into Russian hands.
