On October 6, 1920, Żeligowski informed his officers of the plans for mutiny; at that point, no one under his command knew that he was acting with Piłsudski's backing, and some refused to follow him.
Żeligowski's forces-numbering some 14,000, centered on his 1st Lithuanian-Belarusian Infantry Division[REF]-defeated the Lithuanian 4th Infantry Regiment near the Rūdininkai Forest, and again in a skirmish near Jašiūnai.
