The Battle of Budriai was fought on 7 July 1655 when Jerzy Wisniewski's company of Polish-Lithuanian mercenaries ambushed and destroyed a Swedish patrol near Budriai in Samogitia.
As Poland's armies moved north to threaten Swedish control over Lithuania and Livonia, Wisniewski embarked on a guerrilla campaign against Swedish targets along the Baltic coast. His first prey was Torbjörn Jansson's Swedish patrol due east of Plunge. The 12-man patrol's cavalry was massacred by the superior Polish riders, but Swedish pikemen killed a Polish horseman before they, too, fell to Polish swords. Only one Swede escaped, and the Poles plundered the vanquished patrol's supplies.
