Florin-Nicolae Ardelean: On the Foreign Mercenaries and Early Modern Military Innovations in East Central Europe. Castaldo's Army in Transsylvania and the Banat
Italian, German, Czech, etc.) fought against or together with Transylvanians sharing thus their knowledge and war experience. The initiative of the Habsburgs to recruit local mercenaries in addition to the foreign ones also contributed to the dissemination of new military ideas. The Habsburgs brought a new model of military organization with a complex hierarchy of officers and civil officials who tended to the diverse needs of a modern army. In the following decades the Transylvanians imitated this model, to a certain extent. Castaldo played a decisive role in bringing the New Italian Type fortification to Transylvania. The Italian general brought several Italian architects and craftsmen of different origins to work on the defensive system of Transylvania. At the same time the Habsburg army brought modern weapons and war supplies. One of the most important achievements in this field was the organisation of the arsenal in Nagyszeben. The purpose of the arsenal was to coordinate the activities ofbuilding fortifications and supplying them with weapons and ammunition. In fact the Transylvanian principality benefited from the 1551- 1553 Habsburg experience. The failure of Castaldo's rule and the unimpressive performance of his army was a lesson well learned by the future rulers of the principality. It showed the limits of a centralized political authority and the great financial burden of supporting a large permanent military force.
