death. Stephen reformed the army by promoting men from the landed free peasantry răzeși (i.e. something akin to freeholding yeomen) to infantry (voinici) and light cavalry (hânsari), reducing his dependence on the boyars, and introduced guns. The Small Host (Oastea Mică) consisted of around 10,000 to 12,000 men. The Large Host (Oastea Mare), which could reach up to 40,000, was recruited from all the free peasantry older than 14 and strong enough to carry a sword or use a bow. This seldom happened, for such a levée en masse was devastating for both economy and population growth. In the Battle of Vaslui, Stephen had to summon the Large Host and also recruited mercenary troops. In the Middle Ages and early Renaissance, the Moldavians relied on light cavalry (călărași) which used hit-and-run tactics similar to those of the Tatars; this gave them great mobility and also flexibility, in case they found it more suitable to dismount their horses and fight in hand-to-hand combat, as it happened in 1422, when 400 horse archers were sent to aid Jagiellon Poland, Moldavia's overlord against the Teutonic Knights. When making eye-contact with the enemy, the horse archers would withdraw to a nearby forest and camouflage themselves with leaves and branches; according to Jan Długosz, when the enemy entered the wood, they were "showered with arrows" and defeated. The heavy cavalry consisted of the nobility, namely, the boyars, and their guards, the viteji (lit. "brave ones", small nobility) and the curteni (court cavalry). These were all nominally part of the Small Host. In times of war, boyars were compelled by the feudal system of allegiance to supply the prince with troops in accordance with the extent of their manorial domain. Other troops consisted of professional foot soldiers (lefegii) which fulfilled the heavy infantry role, and the plăieși, free peasants whose role was that of border guards: they guarded the mountain passes and were prepared to ambush the enemy and to fight delaying actions. In the absence of the prince, command was assigned to the Mare Spătar (Grand Sword-Bearer, a military office) or to the Mare Vornic (approx. Governor of the Country; a civilian office second only to the Voievod, which was filled by the prince himself). Supplying the troops was by tradition-later-made-into-law the duty of the inhabitants of those lands on which the soldiers were present at a given time. The Moldavians' (as well as Wallachians')
