At that time the gateways were the only part of the fortifications made of stone. The ramparts were of earth, planted on the exterior slope with a thick mass of thorn-bushes, interlaced and strengthened by posts. Outside there were more defences of wooden stockades, and beyond them two ditches, divided by a dyke, on which was a palisade of pointed stakes. The town, thus fortified, was defended by about 10,000 men, and on June 8, 1383, the siege was begun by a force consisting of 17,000 English and 20,000 Flemings of the national party, most of whom came from Bruges and Ghent. The English had been told that the town would not offer a strong resistance, and on the first day of the siege 1,000 of them tried to carry it at once by assault. They were repulsed; and after that assaults by the besiegers and sorties by the garrison continued day after day, the loss of life on both sides being very great. At last the besiegers, finding that they could not, in the face of the shower of arrows, javelins, and stones which met them, break through the palisades and the sharp thorn fences (those predecessors of the barbed-wire entanglements of to-day), force the gates, or carry the ramparts, built three wooden towers mounted on wheels, and pushed them full of soldiers up to the gates. But the garrison made a sortie, seized the towers, destroyed them, and killed or captured the soldiers who manned them. Spencer on several occasions demanded the surrender of the town, but all his proposals were rejected. The English pressed closer and closer, but were repulsed with heavy losses whenever they delivered an assault. The hopes of the garrison rose high on August 7, the sixty-first day of the siege, when news arrived that a French army, 100,000 strong, accompanied by the forces of the Count of Flanders, was marching to the relief of Ypres. Early next morning the English made a fresh attempt to force their way into the town, but they were once more driven back. A little later in the day they twice advanced with the utmost bravery. Again they were beaten back. So were the burghers of Ghent, whom the English reproached for having deceived them by saying that Ypres would fall in three days, and whose answer to this accusation was a furious attack on one of the gates, in which many of them fell. In the afternoon the English again advanced, and succeeded in forcing their way through part of the formidable thorn hedge; but it was of no avail, and once more they had to retire, leaving heaps of dead behind them. After a rest of some hours, another attack was made on seven different parts of the town at the same time. This assault was the most furious and bloody of the siege, but it was the last. Spencer saw that, in spite of the splendid courage of his soldiers and of the Flemish burghers, it would be impossible to take the town before the French army arrived, and during the night the English, with their allies from Ghent and Bruges, retired from before Ypres.
