The terms upon which the Duke took service under Philip II. are thus stated in a letter of Bernardo Tasso. The King guaranteed him protection for his territories against all hazards, and bound himself to supply and maintain for him a body-guard of at least two hundred infantry, besides a company of a hundred men-at-arms, and another of two hundred light horse. He further engaged to pay him monthly 1000 golden scudi for his appointments as captain-general, besides maintaining for him four colonels and twenty captains. In return, the Duke took an oath to serve his Majesty faithfully against all potentates, the pontiffs alone excepted. The political results of this arrangement were strongly and painfully felt by Bernardo, who regarded it as establishing the tranquillity of Naples, the security of Tuscany, and, in a word, the Spanish domination in Italy. Inclined to the French interests (for there was no longer an Italian party in existence), he would have gladly seen the sovereign of a highland population, whose warlike sinews were not yet quite relaxed, preserve his neutrality, or rather, like his father, attach himself to the republic of Venice, which still possessed much external power and internal independence. Indeed, he laments the short-sighted policy of the Signory, in omitting this opportunity of securing, as an available check upon Spanish influence, an able confederate, and corn-growing neighbour; a blunder which was the more unaccountable, as, in the opinion of Mocenigo, who was Venetian envoy at Urbino many years later, the prepossessions of Guidobaldo were even then in favour of a connection which had hereditary claims upon his preference. On the first days of May the convention was published at Pesaro, after solemn thanksgiving to the Almighty for a dispensation so acceptable to the Duke.[62] The importance to Spain of this condotta may be understood from a fact mentioned by Riposati, that Gubbio alone sent forth, between 1530 and 1570, three captains-general, two lieutenants-general, six colonels, and sixty-five captains of note. Mocenigo says, there were in 1570 twelve thousand soldiers in the duchy, ready at call. [Footnote 62: From an account of this engagement preserved among the Oliveriana MSS., and slightly differing from that by Bernardo Tasso (II., letter 166), we learn that the pay of officers was from 15 to 40 scudi a month, that of cavalry privates 5, and of infantry 3 scudi. It appears to have been worth to Guidobaldo in all about 35,000 scudi a year, but to have been irregularly received.]
