After Matthias's income increased periodically, simultaneously, the number of mercenaries increased as well. Historical records vary when it comes to numbers, mainly because it changed from battle to battle and most soldiers were only employed for the duration of combat or a longer conflict. Reckoning the nobility's banners, the mercenaries, the soldiers of conquered Moravia and Silesia, and the troops of allied Moldavia and Wallachia, the King could have gathered an army of 90,000 men. The nobility's participation in the battlefield were ignored by the time their support could have been redeemed in gold later on. The cities were also relieved of paying war levies if they supplied the craftsmanship and weapon production to equip the military.
