Battle of Prostki

Course of events

Wincenty Gosiewski’s Polish, Lithuanian and Tatar force defeated Swedish-Brandenburg troops. The battle was fought in Ducal Prussia.¹

A closer look

Wincenty Gosiewski’s force combined Polish, Lithuanian and Tatar cavalry. Its opponent was a Swedish-Brandenburg corps in Ducal Prussia. The action shows that the coalition war also unfolded beyond the Crown lands.¹

The river and a feigned retreat

The Polish History Museum describes Waldeck’s camp beside the Ełk and Gosiewski’s feigned flight, which drew the enemy across the river. Lithuanian forces took the camp; the Tatars engaged Bogusław Radziwiłł’s troops, and the prince was captured.²

Wojniłłowicz’s contribution
