Czarnowo, Nowy Dwór Mazowiecki County

Czarnowo [t͡ʂarˈnɔvɔ] is a village in the administrative district of Gmina Pomiechówek, within Nowy Dwór Mazowiecki County, Masovian Voivodeship, in east-central Poland. It lies approximately 2 kilometres (1 mi) south-east of Brody-Parcele (the gmina seat), 8 km (5 mi) north-east of Nowy Dwór Mazowiecki, and 33 km (21 mi) north-west of Warsaw. The village is on the north bank of the Narew River, a short distance east of the point where the Wkra River flows into it from the north.

The Battle of Czarnowo was fought on 23–24 December 1806 during the War of the Fourth Coalition, part of the Napoleonic Wars. French soldiers under the command of Marshal Louis-Nicolas Davout forced a crossing of the Wkra near Pomiechowo. When they advanced eastward to Czarnowo they were fiercely resisted by Russian troops led by Lieutenant General Alexander Ivanovich Ostermann-Tolstoy in an all-night contest. In the early morning hours of the 24th, Ostermann-Tolstoy ordered a retreat. The fighting caused about 1,400 casualties on each side.
