Again it fell to the lot of the Hungarians to deliver Europe from these pests. When there were no more Jews to murder, the bands collected in one body, and took the old route to the Holy Land, a route stained with the blood of three hundred thousand who had gone before, and destined also to receive theirs. The number of these swarms has never been stated; but so many of them perished in Hungary, that contemporary writers, despairing of giving any adequate idea of their multitudes, state that the fields were actually heaped with their corpses, and that for miles in its course the waters of the Danube were dyed with their blood. It was at Mersburg, on the Danube, that the greatest slaughter took place, — a slaughter so great as to amount almost to extermination. The Hungarians for a while disputed the passage of the river, but the crusaders forced their way across, and attacking the city with the blind courage of madness, succeeded in making a breach in the walls. At this moment of victory an unaccountable fear came over them. Throwing down their arms they fled panic-stricken, no one knew why, and no one knew whither. The Hungarians followed, sword in hand, and cut them down without remorse, and in such numbers, that the stream of the Danube is said to have been choked up by their unburied bodies.

This was the worst paroxysm of the madness of Europe; and this passed, her chivalry stepped upon the scene. Men of cool heads, mature plans, and invincible courage stood forward to lead and direct the grand movement of Europe upon Asia. It is upon these men that romance has lavished her most admiring epithets, leaving to the condemnation of history the vileness and brutality of those who went before. Of these leaders the most distinguished were Godfrey of Bouillon Duke of Lorraine, and Raymond Count of Toulouse. Four other chiefs of the royal blood of Europe also assumed the Cross, and led each his army to the Holy Land: Hugh, Count of Vermandois, brother of the King of France; Robert, Duke of Normandy, the elder brother of William Rufus; Robert Count of Flanders, and Boemund Prince of Tarentum, eldest son of the celebrated Robert Guiscard. These men were all tinged with the fanaticism of the age, but none of them acted entirely from religious motives. They were neither utterly reckless like Gautier sans Avoir, crazy like Peter the Hermit, nor brutal like Gottschalk the Monk, but possessed each of these qualities in a milder form; their valour being tempered by caution, their religious zeal by worldly views, and their ferocity by the spirit of chivalry. They saw whither led the torrent of the public will; and it being neither their wish nor their interest to stem it, they allowed themselves to be carried with it, in the hope that it would lead them at last to a haven of aggrandizement. Around them congregated many minor chiefs, the flower of the nobility of France and Italy, with some few from Germany, England, and Spain. It was wisely conjectured that armies so numerous would find a difficulty in procuring provisions if they all journeyed by the same road. They, therefore, resolved to separate, Godfrey de Bouillon proceeding through Hungary and Bulgaria, the Count of Toulouse through Lombardy and Dalmatia, and the other leaders through Apulia to Constantinople, where the several divisions were to reunite. The forces under these leaders have been variously estimated. The Princess Anna Comnena talks of them as having been as numerous as the sands on the sea-shore, or the stars in the firmament. Fulcher of Chartres is more satisfactory, and exaggerates less magnificently, when he states, that all the divisions, when they had sat down before Nice in Bithynia, amounted to one hundred thousand horsemen, and six hundred thousand men on foot, exclusive of the priests, women and children. Gibbon is of opinion that this amount is exaggerated; but thinks the actual numbers did not fall very far short of the calculation. The Princess Anna afterwards gives the number of those under Godfrey of Bouillon as eighty thousand foot and horse; and supposing that each of the other chiefs led an army as numerous, the total would be near half a million. This must be over rather than under the mark, as the army of Godfrey of Bouillon was confessedly the largest when it set out, and suffered less by the way than any other.

The Count of Vermandois was the first who set foot on the Grecian territory. On his arrival at Durazzo he was received with every mark of respect and courtesy by the agents of the Emperor, and his followers were abundantly supplied with provisions. Suddenly however, and without cause assigned, the Count was arrested by order of the Emperor Alexius, and conveyed a close prisoner to Constantinople. Various motives have been assigned by different authors as having induced the Emperor to this treacherous and imprudent proceeding. By every writer he has been condemned for so flagrant a breach of hospitality and justice. The most probable reason for his conduct appears to be that suggested by Guibert of Nogent, who states that Alexius, fearful of the designs of the crusaders upon his throne, resorted to this extremity in order afterwards to force the Count to take the oath of allegiance to him, as the price of his liberation.
