On October 10, 1941 the German commander of Lubny ordered all Jews from the town and the rest of the county to gather on October 15 (October 16, according to another source) in the outlying part of Lubny named Zasulye (another source says Zamostye Street), on the pretext that they were being relocated. At 9 a.m. of that day about 4,500 Jews who were assembled in Zasulye were surrounded by Sonderkommando 4a and their local collaborators near the rope factory and forced to undress. Then they were made to run, in groups of 35-40, to anti-tank trenches located near the factory, where they were shot.
