Haisyn is a settlement in the Vinnytsia region of Ukraine, in which, according to the 1939 census, 4.1 thousand Jews lived. They constituted 27.7% of the local population.

Information about the number of those called up to the Red Army and evacuated has not been preserved. Nevertheless, there is evidence that a Jewish partisan detachment operated in the Shcheblyansky forest near Haisyn during the years of occupation. The majority of them were women and children, so historians doubt the combat capability of the unit. However, its presence is indirect evidence that the Jewish population of the Haisyn region fled from the Nazi occupation.

Haisyn was captured by German troops in July 1941. Unlike many other settlements in Vinnytsia region, the city ended up in the German occupation zone and became part of the Reichskommissariat Ukraine, and not Transnistria controlled by Romania.

In early August 1941, the invaders registered the Jewish population of Haisyn. A little later in the same month, all the Jews were herded into the ghetto, which was located on Rabochaya Street. In addition to the Haisyn Jews, Jews from nearby settlements, who were taken to the city by the Nazis from the end of August 1941, ended up in the ghetto.

In addition to the ghetto, the Nazis created a concentration camp in the village. It housed Jews from Bukovina and Bessarabia occupied by Romanian troops. The Nazis used the prisoners of the camp for construction work. The prisoners worked on the construction of a bridge on the way to Vinnytsia. It is known that about a thousand Jews were shot during the work and buried at the construction site.

The extermination of the prisoners of the Haisyn ghetto took place in two stages. The Nazis carried out the first extermination aktion in September 1941. Then, according to researchers, the invaders killed about 1.3 thousand Jews, among whom a significant part were women and children. According to other sources, the death toll reached 3 thousand.

A month later, in October 1941, the Nazis carried out another mass execution. According to the recollections of eyewitnesses, the prisoners were gathered in the area of ​​the city shooting gallery, stripped and driven to the place of execution in the Belendiyka tract. Here, during 32 months of occupation, the Nazis, according to various estimates, destroyed from 8 to 10 thousand Jews from the city of Haisyn and adjacent settlements.

After the extermination aktion in October 1941, the Nazis left about 150 alive. They were used for forced labor until May 1942, after which they were shot.

About 20 Jews survived the occupation of the city.
