Unfortunately for the States, the fortifications of Liefkenshoek, on the Flemish side of the river, had not been entirely completed. Eight hundred men lay within it, under Colonel John Pettin of Arras, an old patriotic officer of much experience. Parma, after reconnoitring the place in person, despatched the famous Viscount of Ghent--now called Marquis of Roubaix and Richebourg--to carry it by assault. The Marquis sent one hundred men from his Walloon legion, under two officers, in whom he had confidence, to attempt a surprise, with orders, if not successful, to return without delay. They were successful. The one hundred gained entrance into the fort at a point where the defences had not been put into sufficient repair. They were immediately followed by Richebourg, at the head of his regiment. The day was a fatal one. It was the 10th July, 1584 and William of Orange was falling at Delft by the hand of Balthazar Gerard. Liefkenshoek was carried at a blow. Of the eight hundred patriots in the place, scarcely a man escaped. Four hundred were put to the sword, the others were hunted into the river, when nearly all were drowned. Of the royalists a single man was killed, and two or three more were wounded. "Our Lord was pleased," wrote Parma piously to Philip, that we "should cut the throats of four hundred of them in a single instant, and that a great many more should be killed upon the dykes; so that I believe very few to have escaped with life. We lost one man, besides two or three wounded." A few were taken prisoners, and among them was the commander John Pettin. He was at once brought before Richebourg, who was standing in the presence of the Prince of Parma. The Marquis drew his sword, walked calmly up to the captured Colonel, and ran him through the body. Pettin fell dead upon the spot. The Prince was displeased. "Too much choler, Marquis, too much choler,"--said he reprovingly. "Troppa colera, Signor Marchese, a questa." But Richebourg knew better. He had, while still Viscount of Ghent, carried on a year previously a parallel intrigue with the royalists and the patriots. The Prince of Parma had bid highest for his services, and had, accordingly, found him a most effectual instrument in completing the reduction of the Walloon Provinces. The Prince was not aware, however, that his brave but venal ally had, at the very same moment, been secretly treating with William of Orange; and as it so happened that Colonel Pettin had been the agent in the unsuccessful negotiation, it was possible that his duplicity would now be exposed. The Marquis had, therefore, been prompt to place his old confederate in the condition wherein men tell no tales, and if contemporary chronicles did not bely him, it was not the first time that he had been guilty of such cold-blooded murder. The choler had not been superfluous.
