For what concerns ourselves, who are not so scrupulous in this affair, and who attribute the honour of the war to him who has the profit of it, and who after Lysander say, "Where the lion's skin is too short, we must eke it out with a bit from that of a fox"; the most usual occasions of surprise are derived from this practice, and we hold that there are no moments wherein a chief ought to be more circumspect, and to have his eye so much at watch, as those of parleys and treaties of accommodation; and it is, therefore, become a general rule amongst the martial men of these latter times, that a governor of a place never ought, in a time of siege, to go out to parley. It was for this that in our fathers' days the Seigneurs de Montmord and de l'Assigni, defending Mousson against the Count of Nassau, were so highly censured. But yet, as to this, it would be excusable in that governor who, going out, should, notwithstanding, do it in such manner that the safety and advantage should be on his side; as Count Guido di Rangone did at Reggio (if we are to believe Du Bellay, for Guicciardini says it was he himself) when the Seigneur de l'Escut approached to parley, who stepped so little away from his fort, that a disorder happening in the interim of parley, not only Monsieur de l'Escut and his party who were advanced with him, found themselves by much the weaker, insomuch that Alessandro Trivulcio was there slain, but he himself follow the Count, and, relying upon his honour, to secure himself from the danger of the shot within the walls of the town.
Eumenes, being shut up in the city of Nora by Antigonus, and by him importuned to come out to speak with him, as he sent him word it was fit he should to a greater man than himself, and one who had now an advantage over him, returned this noble answer. "Tell him," said he, "that I shall never think any man greater than myself whilst I have my sword in my hand," and would not consent to come out to him till first, according to his own demand, Antigonus had delivered him his own nephew Ptolomeus in hostage.
And yet some have done very well in going out in person to parley, on the word of the assailant: witness Henry de Vaux, a cavalier of Champagne, who being besieged by the English in the Castle of Commercy, and Bartholomew de Brunes, who commanded at the Leaguer, having so sapped the greatest part of the castle without, that nothing remained but setting fire to the props to bury the besieged under the ruins, he requested the said Henry to come out to speak with him for his own good, which he did with three more in company; and, his ruin being made apparent to him, he conceived himself singularly obliged to his enemy, to whose discretion he and his garrison surrendered themselves; and fire being presently applied to the mine, the props no sooner began to fail, but the castle was immediately blown up from its foundations, no one stone being left upon another.
I could, and do, with great facility, rely upon the faith of another; but I should very unwillingly do it in such a case, as it should thereby be judged that it was rather an effect of my despair and want of courage than voluntarily and out of confidence and security in the faith of him with whom I had to do.
