The extermination of Jews by Nazi Germany in the territory of the Republic of Poland during World War II was an operation on a grant scale. There remain small towns and villages where the Jews often accounted for a majority of the inhabitants but nothing is known about their fate. The such localities are the adjacent villages Siniawka and Naruszewicze, then situated in Nieśwież powiat, Nowogródek voivodship. Just before World War II, both villages were inhabited by between 1,200 and 1,300 people, some 700 of whom were ethnic Jews.
Around the end of July or beginning of August 1941, the Nazis set up a ghetto for Siniawka and Naruszewicze Jews in Siniawka.
On the day of their extermination, the ghetto residents were gathered by the Germans in Siniawkas market square. The attendance list of ghetto residents was checked with the help of Judenrat members. Those who were missing were trucked to the market and those who were too ill or crippled to walk there were killed in their homes. Then the Jews (whole families, with wives and children) were marched to the edge of the forest, where the men were first asked to dig up a pit. That is where the Jews from Siniawka ghetto were murdered. In all likelihood, no one survived.
Ater World War II the two villages became part of what is now Belarus, which complicates access to sources of information because the political situation in Belarus prevents the conducting of more detailed research in Byelorussian archives. Access is barred to any person who is not a Byelorussian citizen. The facts presented in the article have not been described in Poland so far.
