Was Skalat on the border between Poland and USSR before WW2? Is there a pre-WW2 map with Skalat? I am trying to confirm information from a 90-year old who reportedly crossed the former border between Poland and USSR during WW2 (July, 1941) at Skalat.
You could check Wikipedia
In the immediate post-World War One period, Skalat was seized by local Ukrainian activists, who declared that the town was part of West Ukrainian People's Republic. Polish - Ukrainian tension escalated, and climaxed in the Polish–Ukrainian War. On April 23, 1919, Ukrainian activists murdered a popular Roman Catholic parish priest from Skalat, Rev. Walerian Raba, and on July 16, 1919, the town was captured by the Polish Army.
In 1923 Skalat became the seat of a county in the Tarnopol Voivodeship.
Tarnopol Voivodeship was an administrative region of interwar Poland (1918–1939)
There is also a Map in wikipedia where you can see, that Skalat is near the border to USSR (Ucraine).

You see, the town is near the border and changed the ruler.
