Treblinka is a village located in eastern Poland, situated in the present-day district of Gmina Małkinia Górna, within Ostrów Mazowiecka County in Masovian Voivodeship, some north-east of Warsaw. The village lies close to the Bug River. It has 350 inhabitants. It is known as the site during World War II of one of the Nazi extermination camps, named after the village. An estimated 850,000 people were murdered here during the Holocaust in Poland, from the summer of 1942 to October 1943. In addition, the Treblinka I Arbeitslager, a forced labor camp, had operated about six miles away, from June 1941 to 23 July 1944. During this period, more than 10,000 prisoners are estimated to have died from executions, malnutrition, disease and mistreatment. World War II history Treblinka was the location of Treblinka extermination camp, where an estimated 850,000 people were systematically murdered during the Holocaust in Poland. About 800,000 of them were Polish Jews. The first deportations took place in the course of the Grossaktion Warsaw with about 254,000 Warsaw Ghetto inmates brought in to their deaths in Holocaust trains in the summer of 1942. At the layover yard of Treblinka railway station, the wagons waiting for "processing" were witnessed by Franciszek Ząbecki. During the early period of the camp's operation, when thousands of dead bodies of victims were left unburied, the putrid odor of decaying human remains could be smelled for approximately in every direction. It was evident that mass extermination was taking place at the camp, which caused panic among the villagers. The onset of the Warsaw Ghetto Uprising inspired renewed hopes for an escape among the Treblinka Sonderkommandos. On 19 April 1943 one of the last Jewish transports of 7,000 victims, along with the Warsaw insurgents, were brought in for gassing. Soon after the first prisoner uprising at a death camp against the SS erupted on 2 August 1943, under the leadership of former Polish Army officer Dr. Berek Lajcher. Some of these prisoners were aided in escaping across the Bug River by the Polish resistance, but few survived. The first commandant of the camp, from until 31 August 1942, was Irmfried Eberl, relieved of his duties for not being efficient and secretive enough about the camp's murder operation. He was succeeded by Franz Stangl (previously the commandant of Sobibor extermination camp) as the second commandant of Treblinka II Vernichtungslager from 1 September 1942 until the 1943
