The Estonian 1st Division and the White Russian Northwestern Division were pushed beyond the Soviet-Estonian border. The division protected the border from January to May 1920. In May and June the division was called to participate in an offensive against Poland. By July and August the fighting was intensifying in the Dokshitsy region.
