The king of Denmark then, as I have said, was the only obstacle to William’s uninterrupted enjoyment: on whose account he enlisted such an immense multitude of stipendiary soldiers out of every province on this side the mountains, that their numbers oppressed the kingdom. But he, with his usual magnanimity, not regarding the expense, had engaged even Hugo the Great, brother to the king of France, with his bands to serve in his army. He was accustomed to stimulate and incite his own valour, by the remembrance of Robert Guiscard; saying it was disgraceful to yield, in courage, to him whom he surpassed in rank. For Robert, born of middling parentage in Normandy, that is, neither very low nor very high, had gone, a few years before William’s arrival in England, with fifteen knights, into Apulia, to remedy the narrowness of his own circumstances, by entering into the service of that inactive race of people. Not many years elapsed, ere, by the stupendous assistance of God, he reduced the whole country under his power. For where his strength failed, his ingenuity was alert: first receiving the towns, and after, the cities into confederacy with him. Thus he became so successful, as to make himself duke of Apulia and Calabria; his brother Richard, prince of Capua; and his other brother, Roger, earl of Sicily. At last, giving Apulia to his son Roger, he crossed the Adriatic with his other son Boamund, and taking Durazzo, was immediately proceeding against Alexius, emperor of Constantinople, when a messenger from pope Hildebrand stopped him in the heat of his career. For Henry, emperor of Germany, son of that Henry we have before mentioned, being incensed against the pope, for having excommunicated him on account of the ecclesiastical investitures, led an army against Rome; besieged it; expelled Hildebrand, and introduced Guibert of Ravenna. Guiscard learning this by the letter of the expelled pope, left his son Boamund, with the army, to follow up his designs, and returned to Apulia; where quickly getting together a body of Apulians and Normans, he proceeded to Rome. Nor did Henry wait for a messenger to announce his approach; but, affrighted at the bare report, fled with his pretended pope. Rome, freed from intruders, received its lawful sovereign; but soon after again lost him by similar violence. Then too, Alexius, learning that Robert was called home by the urgency of his affairs, and hoping to put a finishing hand to the war, rushed against Boamund, who commanded the troops which had been left. The Norman youth, however, observant of his native spirit, though far inferior in number, turned to flight, by dint of military skill, the undisciplined Greeks and the other collected nations. At the same time, too, the Venetians, a people habituated to the sea, attacking Guiscard, who having settled the object of his voyage was now sailing back, met with a similar calamity: part were drowned or killed, the rest put to flight.
