At last, Henry, attended by the duke of Buckingham and many others of the nobility, arrived at Calais, and entered upon his French expedition, from which he fondly expected so much success and glory.[*] Of all those allies on whose assistance he relied, the Swiss alone fully performed their engagements. Being put in motion by a sum of money sent them by Henry, and incited by their victories obtained in Italy and by their animosity against France, they were preparing to enter that kingdom with an army of twenty-five thousand men; and no equal force could be opposed to their incursion. Maximilian had received an advance of one hundred and twenty thousand crowns from Henry, and had promised to reënforce the Swiss with eight thousand men, but failed in his engagements. That he might make atonement to the king, he himself appeared in the Low Countries, and joined the English army with some German and Flemish soldiers, who were useful in giving an example of discipline to Henry’s new-levied forces. Observing the disposition of the English monarch to be more bent on glory than on interest, he enlisted himself in his service, wore the cross of St. George, and received pay, a hundred crowns a day, as one of his subjects and captains. But while he exhibited this extraordinary spectacle, of an emperor of Germany serving under a king of England, he was treated with the highest respect by Henry, and really directed all the operations of the English army. * Polyd. Virg. lib. xxvii. Bellarius, lib. xiv. Before the arrival of Henry and Maximilian in the camp, the earl of Shrewsbury and Lord Herbert had formed the siege of Terouane, a town situated on the frontiers of Picardy; and they began to attack the place with vigor. Teligni and Crequi commanded in the town, and had a garrison not exceeding two thousand men; yet made they such stout resistance as protracted the siege a month; and they at last found themselves more in danger from want of provisions and ammunition than from the assaults of the besiegers. Having conveyed intelligence of their situation to Lewis, who had advanced to Amiens with his army, that prince gave orders to throw relief into the place. Fontrailles appeared at the head of eight hundred horsemen, each of whom carried a sack of gunpowder behind him, and two quarters of bacon. With this small force he made a sudden and unexpected irruption into the English camp, and, surmounting all resistance, advanced to the fosse of the town, where each horseman threw down his burden. They immediately returned at the gallop, and were so fortunate as again to break through the English and to suffer little or no loss in this dangerous attempt.[*]
