Long Live the Republic (1965)

Olda Zdenek Lsiburek is a young Moravian boy subjected to beatings at home from his heartless father and taunts from other children because of his short stature. The boy's mother is his only protector while the father is more concerned with having his horse confiscated by the army. Olda is ordered by his father to take the horse into the woods to hide it from the troops, but the Nazis capture the animal. Olda risks his life by sneaking into a Russian Army camp to steal a horse rather than face the punishment from his father.
