The citizens of Ypres took a prominent part in most of the great events which distinguished the heroic period of Flemish history. In July, 1302, a contingent of 1,200 chosen men, '500 of them clothed in scarlet and the rest in black,' were set to watch the town and castle of Courtrai during the Battle of the Golden Spurs, and in the following year the victory was celebrated by the institution of the Confraternity of the Archers of St. Sebastian, which still exists at Ypres, the last survivor of the armed societies which flourished there during the Middle Ages. Seven hundred burghers of Ypres marched to Sluis, embarked in the Flemish boats which harassed the French fleet during the naval fight of June, 1340, and at the close of the campaign formed themselves into the Confraternity of St. Michael, which lasted till the French invasion of 1794. Forty years later we find no fewer than 5,000 of the men of Ypres, who had now changed their politics, on the French side at the Battle of Roosebeke, fighting in the thick mist upon the plain between Ypres and Roulers on that fatal day which saw the death of Philip van Artevelde and the triumph of the Leliarts. [Illustration: ADINKERQUE. At the Kermesse.] Next year, so unceasingly did the tide of war flow over the plain of Flanders, an English army, commanded by Henry Spencer, Bishop of Norwich, landed at Calais under the pretext of supporting the partisans of Pope Urban VI., who then occupied the Holy See, against the adherents of Pope Clement VII., who had established himself at Avignon. The burghers of Ghent flocked to the English standard, and the allies laid siege to Ypres, which was defended by the French and the Leliarts, who followed Louis of Maele, Count of Flanders, and maintained the cause of Clement. 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 un 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.
