In his school the great condottieri Braccio da Montone and Sforza Attendolo were formed; and henceforth the battles of Italy were fought by Italian generals commanding native troops.
Cesare arrived at that town, decoyed the unsuspecting condottieri into his house, had them all arrested, and two of them, Vitelli and Oliverotto, strangled (December 31,1502).
Of this by far the most important member was Federigo da Montefeltro, lord of Urbino from 1444 to 1482, one of the most successful condottieri chiefs of his time, and not only a man of great military and political ability, but also an enthusiastic patron of art and literature, on which he lavished immense sums of money.
Abandoned by a number of his cardinals, condemned by most of the powers, deprived of his dominions by condottieri who shamelessly invoked the authority of the council, the pope made concession after concession, and ended on the 15th of December 1 433 by a pitiable surrender of all the points at issue in a bull, the terms of which were dictated by the fathers of Basel, that is, by declaring his bull of dissolution null and void, and recognizing that the synod had not ceased to be legitimately assembled.
The purely selfish bond between condottieri and their employers, whether princes or republics, involved intrigues and treachery, checks and counterchecks, secret terror on the one hand and treasonable practice on the other, which ended by making statecraft in Italy synonymous with perfidy.
