Given name: Unknown Family name: Winogronow

The Germans surrounded Winogronow and Rozowski's units, which were situated in the attic at Nowolipki Street No. 43. The defenders threw grenades at the Germans, who withdrew but came back with reinforcements; they cleared their way to the stairs which led to the attic. The only exit for the group was a secret passage to the neighbours' house, yet they could not get there as the enemy's machine-gun was shooting right at them. "Let's try to silence the gun" said Gabriel Frishdorf, he approached the small window, hid after the mattress, aimed the revolver and calmed down the gun. The group escaped.

Perhaps it is Winogorn?
