On the 17th June the foe sprang a mine under the western bulwark; close to a countermine exploded by the garrison the day before. The assailants thronged as merrily as usual to the breach, and were met with customary resolution by the besieged; Governor Uytenhoove, clad in complete armour, leading his troops. The enemy, after an hour's combat, was repulsed with heavy loss, but the governor fell in the midst of the fight. Instantly he was seized by the legs by a party of his own men, some English desperadoes among the number, who, shouting that the colonel was dead, were about to render him the last offices by plundering his body. The ubiquitous Fleming, observing the scene, flew to the rescue and, with the assistance of a few officers, drove off these energetic friends, and taking off the governor's casque, discovered that he still breathed. That he would soon have ceased to do so, had he been dragged much farther in his harness over that jagged and precipitous pile of rubbish, was certain. He was desperately wounded, and of course incapacitated for his post. Thus, in that year, before the summer solstice, a fifth commandant had fallen. On the same day, simultaneously with this repulse in the West Bulwark, the enemy made himself at last completely master of the Polder. Here, too, was a savage hand-to-hand combat with broadswords and pikes, and when the pikes were broken, with great clubs and stakes pulled from the fascines; but the besiegers were victorious, and the defenders sullenly withdrew with their wounded to the inner entrenchments. On the 27th June, Daniel de Hartaing, Lord of Marquette, was sent by the States-General to take command in Ostend. The colonel of the Walloon regiment which had rendered such good service on the famous field of Nieuport, the new governor, with his broad, brown, cheerful face, and his Milan armour, was a familiar figure enough to the campaigners on both sides in Flanders or Germany.
