After a short rest the regiment marched towards the forests near Dąbrowa Wielka. In the night of September 12, remnants of 2nd Uhlan Regiment, destroyed by the Wehrmacht in the Battle of Wizna, reached the same forest. Colonel Karol Anders of 2nd Regiment took over command of the united forces. On the next day a column of German motorized infantry set off from Czyżew, trying to destroy Polish cavalry. Near the village of Kamien, Polish soldiers halted the enemy, destroying 10 tanks and capturing a number of prisoners.
