To the amazement of all Flanders the challenge, delivered in the presence of Count Charles and all his court, was refused. Walter, whom the historians call "the Winged Lie," proclaimed that he would fight only with a free man, and that the Lord of Raeske, by wedding a serf, had become a serf himself. This was in accordance with a law recently promulgated by Charles, but the house of Erembald, perceiving that its very existence was threatened by the charge, fiercely repelled the accusation and was supported not only by all of the Karls, but by most of the feudal nobility as well--the latter no doubt fearing lest one of their own houses might be attainted in a similar manner at any moment. The country was plunged into what was virtually civil war, when Charles was suddenly summoned by his feudal over-lord, the King of France, to come to his aid at Clermont. On his return, assured of the King's powerful support, Charles undoubtedly meditated the complete overthrow of the Erembalds, whom he had steadfastly claimed as his vassals since "the Winged Lie" had denounced them as serfs. He arrived at Bruges late in the evening, and early the following day, March 1, 1127, repaired to St. Donatian to hear mass. It was a foggy morning and the Count went almost unattended. Hardly had he knelt before the altar when a party of followers of the attainted house of Erembald swarmed into the church and he was struck down before he had time to rise, much less to defend himself. If, in his lifetime, the Count was a dangerous foe to the Erembalds, in his death he proved to be far more deadly. As his body lay on the stone floor of the great church, clad in the crimson robe the chroniclers so often allude to, and surrounded with flaming torches, the heads of the house hastily consulted as to what was to be done with it. To inter the body at Bruges would be to risk an outbreak of popular passion at the murder, and it was decided to secretly convey it away. This plan was rudely frustrated by a mob of citizens who forcibly prevented the removal of the body, which was therefore laid to rest with imposing ceremonies in the very church where the Count had been assassinated. Meanwhile the story of the murder spread far and wide, and, in a few days, a huge host was marching on Bruges from every part of Flanders. For a time the burghers stood by the Châtelain and the Provost, but when the city was entered by stratagem and the Erembalds driven back into the Bourg the mass of the citizens went over to the side of the avengers. After a short defence the Bourg in turn was captured--its defenders failing to guard one small gate by which their enemies entered unopposed--and the remnant of the Erembalds fled into the very church that had been defiled by their kinsmen's crime, St. Donatian. Here, for a time, they were left in peace while the victors pillaged the rich palaces in the ancient Bourg.
