Guise was far from expecting so sudden and decisive a result. “Sing me no more flattering strains in your letters about the emperor’s dislodgment hence,” he wrote on the 24th of December to his brother the Cardinal of Lorraine; “take it for certain that unless we be very much mistaken in him, he will not, as long as he has life, brook the shame of departing hence until he has seen it all out.” Irritated, and, perhaps, still more shocked, at so heavy a blow to his power and his renown, Charles V. looked everywhere for a chance of taking his revenge. He flattered himself that he had found it in Therouanne, a fortress of importance at that time between Flanders and Artois, which had always been a dependency of the kingdom of France, and served as a rampart against the repeated incursions of the English, the masters of Calais. Charles knew that it was ill supplied with troops and munitions of war; and the court of Henry II., intoxicated with the deliverance of Metz, spoke disdainfully of the emperor, and paid no heed to anything but balls, festivities, and tournaments in honor of the marriage between Diana d’Angouleme, the king’s natural daughter, and Horatio Farnese, Duke of Castro. All on a sudden it was announced that the troops of Charles V. were besieging Therouanne. The news was at first treated lightly; it was thought sufficient to send to Therouanne some re-enforcements under the orders of Francis de Montmorency, nephew of the constable; but the attack was repulsed with spirit by the besiegers, and brave as was the resistance offered by the besieged, who sustained for ten hours a sanguinary assault, on the 20th of June, 1553, Francis de Montmorency saw the impossibility of holding out longer, and, on the advice of all his officers, offered to surrender the place; but he forgot to stipulate in the first place for a truce; the Germans entered the town, thrown open without terms of capitulation; it was given up as prey to an army itself a prey to all the passions of soldiers as well as to their master’s vengeful feelings, and Therouanne, handed over for devastation, was for a whole month diligently demolished and razed to the ground. When Charles V., at Brussels, received news of the capture, “bonfires were lighted throughout Flanders; bells were rung, cannon were fired.” It was but a poor revenge for so great a sovereign after the reverse he had just met with at Metz; but the fall of Therouanne was a grievous incident for France. Francis I. was in the habit of saying that Therouanne in Flanders and Acqs (now Dax) on the frontier of Guienne were, to him, like two pillows on which he could rest tranquilly.
