On the web, you find some pages mentioning "Kyeltsi", a town in Poland - all about warfare in WW1, 1914. But what and where is Kyeltsi? It's not mentioned anywhere else.
does kyeltsi still exist? that is one factor, i need to do some research myself to familiarize myself with the area...
I'm not 100% sure, but I believe Kyelsti used to Belong to the former Austrian-Hungarian Empire, in a province called Galicia. After WWI this area was given to Poland (East of Silezia in southern Poland) . When the soviets invaded Poland, Former Galicia was again divided and the Russia annexed the Lvow (Lemberg) territory as part of their Brest Littow border.
That's right. Incredible how often these places changed names and were annexed by such and such a country.
