It was the destiny of Urbino long to endure the full weight of Malatesta's troublesome qualities; to be in turn agitated by his intrigues, compromised by his instability, deluded by his duplicity, harassed anew by his inroads, and again cajoled by his hollow repentance. The Count, whose sense of honour was delicately susceptible, and who felt warmly for his people's welfare, could no longer brook such aggressions. Bent upon signally punishing them, he, however, before concerting measures with Alfonso, judged it prudent to visit Florence, Bologna, Milan, and Mantua, in order to justify to their governments the necessity of making an example of his inveterate foe. Nothing could exceed the honourable reception accorded him at these places; but he did not obtain anything beyond general assurances or cold civilities in regard to the matter he had in view. The proffered mediation of Borso d'Este, Duke of Modena and Marquis of Ferrara, held out one last hope of an arrangement; so he paid him a visit on his return homewards, in May, 1457, and found that Malatesta was already his guest. The interview of these rivals is described by Sanzi and Baldi with details probably more dramatic than historical. The Lord of Rimini came reluctantly, with arms at his side and implacable passions in his breast; he commenced the discussion with a long catalogue of grievances, and quickly wrought himself up to violent and insulting language, which Federigo met by mild but firm remonstrance, ending with a proposal to settle by single combat, "hand to hand, in field, or plain, or valley," whatever misunderstandings could not be amicably disposed of by their host. Sigismondo, for answer, drew his sword, and after the parties had exchanged ferocious defiance, the Duke separated them, grieved at the total failure of his intervention. Before leaving Ferrara, the Count offered to submit to his arbitration their differences, the chief of which was as to restoration of the places in Montefeltro retained by Malatesta; but the latter declined any reference of the sort.
