Kosów Podlaski
The Polish underground Memorandum on the Situation in the Country for the Period July 16 –August 25, 1942
claimed four death camps in existence in German-occupied Poland: Bełżec, Treblinka II, Sobibór and one at Kosów Podlaski.
(See Mattogno 2021e, p. 97, for the source.)
No such town exists, but there is a town called Sokołów Podlaski some 80 km east of Warsaw. All historians agree, however, that no such camp with any mass-murder facility ever existed in or near this or any similarly named town. This phantom extermination camp is a creation of black-propaganda sources.
