The whole force, exclusive of the English, amounted to thirty-five thousand foot and twelve thousand horse, besides a good train of battering artillery.[191] The command of this army was given to Emanuel Philibert, prince of Piedmont, better known by his title of duke of Savoy. No man had a larger stake in the contest, for he had been stripped of his dominions by the French, and his recovery of them depended on the issue of the war. He was at this time but twenty-nine years of age; but he had had large experience in military affairs, and had been intrusted by Charles the Fifth, who had early discerned his capacity, with important commands. His whole life may be said to have trained him for the profession of arms. He had no taste for effeminate pleasures, but amused himself, in seasons of leisure, with the hardy exercise of the chase. He strengthened his constitution, naturally not very robust, by living as much as possible in the open air. Even when conversing, or dictating to his secretaries, he preferred to do so walking in his garden. He was indifferent to fatigue. After hunting all day he would seem to require no rest, and in a campaign had been known, like the knights-errant of old, to eat, drink, and sleep in his armor for thirty days together. He was temperate in his habits, eating little, and drinking water. He was punctual in attention to business, was sparing of his words, and, as one may gather from the piquant style of his letters, had a keen insight into character, looking below the surface of men's actions into their motives.[192] His education had not been neglected. He spoke several languages fluently, and, though not a great reader, was fond of histories. He was much devoted to mathematical science, which served him in his profession, and he was reputed an excellent engineer.[193] In person the duke was of the middle size; well-made, except that he was somewhat bow-legged. His complexion was fair, his hair light, and his deportment very agreeable. Such is the portrait of Emanuel Philibert, to whom Philip now intrusted the command of his forces, and whose pretensions he warmly supported as the suitor of Elizabeth of England. There was none more worthy of the royal maiden. But the duke was a Catholic; and Elizabeth, moreover, had seen the odium which her sister had incurred by her marriage with a foreign sovereign. Philip, who would have used some constraint in the matter, pressed it with such earnestness on the queen as proved how much importance he attached to the connection. Mary's conduct on the occasion was greatly to her credit; and, while she deprecated the displeasure of her lord, she honestly told him that she could not in conscience do violence to the inclinations of her sister.[194]
