@GaiusCoriolanus Yes, I was surprised to see that Volyn Ukrainians served for the Polish side. Then, again, they were Polish nationals (citizens of Poland). There were also Volhynians loyal to Russia, because they were under Russian rule for a century.
When the television movie aired in Ukraine, many younger Ukrainians made comments about how shocked they were to learn of the UPA murders of Poles in Volyn. They were unaware this happened. These were Ukrainians posting from around Central Ukraine and Kyiv area. They knew very little about Interwar Poland and Volyn. Perhaps this part of Ukraine’s history is not taught in schools?
The entire mini-series is posted on YouTube in Ukrainian language. I wish someone would English sub the complete movie.
