So, it’s still interesting – if a map was added to the game, is it possible to find at least the map itself? It's clear that you won't find such an assembly anywhere. I searched all possible websites, but the result is zero.

Added after 17 hours and 24 minutes

No, the “Ukraine” map definitely isn’t from the standard set: You probably had a pirated build.

It’s funny, but now The Shadow of Death is installed; I downloaded the collection (with Armageddon's Blade and Chronicles), and there are no standard XL or L maps, etc. But it was there. And it seems like I have a licensed version now.
