"Nevertheless, as to cannon-shot, when a body of men are drawn up in the face of a train of artillery, as the occasion of war often requires, it is unhandsome to quit their post to avoid the danger, forasmuch as by reason of its violence and swiftness we account it inevitable; and many a one, by ducking, stepping aside, and such other motions of fear, has been, at all events, sufficiently laughed at by his companions.
And yet, in the expedition that the Emperor Charles V. made against us into Provence, the Marquis de Guast going to reconnoitre the city of Arles, and advancing out of the cover of a windmill, under favour of which he had made his approach, was perceived by the Seigneurs de Bonneval and the Seneschal of Agenois, who were walking upon the ‘theatre aux ayenes’; who having shown him to the Sieur de Villiers, commissary of the artillery, he pointed a culverin so admirably well, and levelled it so exactly right against him, that had not the Marquis, seeing fire given to it, slipped aside, it was certainly concluded the shot had taken him full in the body. And, in like manner, some years before, Lorenzo de’ Medici, Duke of Urbino, and father to the queen-mother—[Catherine de’ Medici, mother of Henry III.]—laying siege to Mondolfo, a place in the territories of the Vicariat in Italy, seeing the cannoneer give fire to a piece that pointed directly against him, it was well for him that he ducked, for otherwise the shot, that only razed the top of his head, had doubtless hit him full in the breast.
To say truth, I do not think that these evasions are performed upon the account of judgment; for how can any man living judge of high or low aim on so sudden an occasion? And it is much more easy to believe that fortune favoured their apprehension, and that it might be as well at another time to make them face the danger, as to seek to avoid it.
For my own part, I confess I cannot forbear starting when the rattle of a harquebuse thunders in my ears on a sudden, and in a place where I am not to expect it, which I have also observed in others, braver fellows than I."
-- Michel de Montaigne, Of Constancy
