Following Ostrovno, there was a running fight between Murat and Osterman-Tolstoy. The Russian stopped just west of Vitebsk when joined by Tuchkov I, who took over command of the rear guard. This was apparently an affront to Tolstoy who remained at the rear according to some accounts and ignored Tuchkov and dove into the thick of the fight by other accounts. In any event, Pahlen, Tuchov, and Tolstoy handily stopped Murat and Eugene, though they did so in vain, as Bagration was already heading for Smolensk, having forsaken a meeting at Vitebsk.

On 25 July 1812, Murat contacted Osterman-Tolstoy in the vicinity of Ostrovno. Tolstoy setup a rear guard position in a heavy wood outside the village. Without waiting for the infantry of Eugene's IV Corps d'armée to come up, Murat ordered a series of useless charges against the Russian line. Eventually, Eugene's lead division arrived on the field, outflanking the Russians, and necessitating their withdrawal east toward Vitebsk.
