[1] On 8 July 1656, Swedish King Charles X Gustav arrived at a military camp of his brother, Duke Adolph John.

The camp was located near Nowy Dwor Mazowiecki, and the two leaders discussed news from Swedish-held town of Tykocin in Podlasie.

The fortress, located along a strategic route from Warsaw to Lithuania and Swedish Livonia, was besieged by Polish - Lithuanian forces of Colonel Samuel Oskierko.

[1] Boguslaw Radziwill, together with Swedish forces under Robert Douglas, Count of Skenninge, left Nowy Dwor on 10 July.

Radziwill immediately attacked Oskierko and his unit, while nobility from Mazovia and Podlasie, unable to fight experienced Swedish soldiers, fled from the battleground.
