On 20 September 1920 Polish troops opened the Battle of the Niemen. A month after his defeat at Warsaw, Mikhail Tukhachevsky had pulled his Western Front back behind the Niemen and the Szczara and was preparing a new offensive toward Białystok and Brest. The Polish Commander-in-Chief, Józef Piłsudski, struck first. While the 2nd Army fought its way toward Grodno, a strike group swung north through Lithuanian-held territory and over the Niemen toward Lida, deep in the Soviet rear. Grodno fell on 25 or 26 September, depending on the source, and Lida soon after. The Red Army fell back east, and a ceasefire followed in October.
