Jan Žižka - the weakest Czech general

Probably should have clarified it, but it's not only related to it, Jan Žižka basically WAS the hussite insurgency.

During the Hussite Wars, multiple countries from all over Europe (with Hungary at the lead) tried to quell the Hussite rebellion, as the Hussites did not like the Catholic church in Rome, because of different ideals, something akin to Martin Luther a few decades after the Hussites (the Hussite wars happened from roughly 1419-1434, while Luther's reformation started in early 1500's). As mentioned in the meme, this crusader army was composed of multiple well trained crusaders, while the Hussite armies were composed of poorly trained peasants. That, however, did not stop the de facto leader of the Hussites, Jan Žižka, to absolutely demolish the crusaders in every battle he's ever fought. All they used was the mentioned poorly trained peasants and some improvised weapons and wooden war wagons from farm equipment. Although it's worth noting that the Hussites also used firearms, which, as far as I know, the crusaders did not use. Jan Žižka was also such an excellent general that not even the fact he lost 1 eye before the Hussite wars and the other eye during the wars, and he was still winning battles. In fact, Žižka never lost a single battle, even while completely blind.

TL;DR: When a crusader army lead by Hungary tried to quell the Hussite movement, Jan Žižka, the leader of the Hussites, defeated the crusaders multiple times with his army of poorly trained peasant army with firearms and improvised farm equipment, even while being completely blind and never losing a single battle.
