The town was occupied by German troops on July 10, 1941. Some local Jewish men were murdered in July – August that year. In the fall of 1941, a ghetto was established in the town, and its Jewish inmates had to wear two yellow Star of David patches, on the front and back of their clothing. A Jew named David, who was not from Krasnoarmeysk, was appointed head of the local Judenrat. According to some testimonies, blood was taken from the ghetto inmates for medical experiments. Testimonies also refer to sick and elderly Jews being taken from the ghetto and gassed. Mass murder operations against the remaining Jews of Krasnoarmeysk and the rest of the county were carried out in September and late December 1941. Krasnoarmeysk was liberated by the Red Army on December 30, 1943.
In 2016, the town reverted to its original name, Puliny.
