Great topic!
For me very personal, because the Czech mercenaries were there too. Talking a lot about our troops on the Polish side, but I must admit that the Czechs fought also on the German side. An important Czech commander on the Polish side was Jan Sokol of Lamberk, such a Czech "condotiero". First You put a really beautifully done figure of Jan Zizka. It is my great idol from childhood, a personification of fortitude, a very significant and unusual personality of Czech medieval history. Zizka´s participation in this campaign is documented, but no direct evidence of his participation in this battle (which we often call Grunwald). But..., if I did this topic I would give him there too. Without him? No imagine ...
Excellent work!
