Prior to the Russian Revolution, the Talalayevka County lay in the eastern part of the Pale of Settlement. For this reason, the village of Galka was home to relatively few Jews, compared to other settlements of the Sumy District.
Following the German invasion of the USSR, a number of civilian evacuees, including many Jews from the western regions of Soviet Ukraine and Belorussia, arrived in the Talalayevka County.
Germans troops occupied Galka in mid-September 1941.
Sometime in the spring of 1942, local policemen arrested a Jew in the village, escorted him to the village of Vedmezhye, and shot him dead there.
The Red Army liberated Galka on September 15, 1943.
