- Aristocratic members
The Sirotci ("Orphans"; {{lang-de|Waisen}}), officially Orphans' Union ({{lang-cz|Sirotčí svaz}}), were followers of a radical wing of the Hussites in Bohemia. This force, founded in 1423 originally under the name Lesser Tábor, consisted mostly of poorer burghers and some members of the lower aristocracy, who joined with commander Jan Žižka and the eastern Bohemian Hussites, the so-called Orebites (Orebité). After the Žižka's death (1424) "orphaned" combatants adopted their new name. From 1424 till 1428 they were led by the priest Ambrož of Hradec, subsequently by another priest Prokop the Lesser. Hejtman Jan Čapek of Sány was elected as their military commander (1431–34). Towns joined with the Union All towns are in Bohemia, unless otherwise noted. - Vysoké Mýto ({{lang-de|Hohenmauth}})
