Battle of Ostrołęka

Revolution & Empire French victory
Historical significance:

Summary

Verdier's division, isolated at Ostrołęka, was attacked by a greatly superior Russian force. Verdier skillfully defended his positions, repulsed several assaults, and retained control of the town after a day of fierce fighting.

Historical context

After Eylau, both armies reorganized. Verdier held Ostrołęka as an outpost of Masséna's corps. The Russian attack sought to test French positions east of the Narew. It was one of the few significant engagements between February and June.

Tactics

Verdier concentrated his infantry in the streets of Ostrołęka and deployed artillery in battery at the entrance to the suburbs. Russian assaults were repulsed thanks to well-prepared defense in depth.

Consequences

Despite numerical superiority, the Russians were repulsed, strengthening Verdier's reputation. Napoleon thus maintained control of bridges over the Narew and slowed Russian initiative in the region.
