The first great western lord to set out for Jerusalem, somewhat paradoxically, was the brother of the king Urban II had excommunicated at Clermont. Hugh count of Vermandois was the younger brother of Philip I, the Fat. Distinguished only by blood, Hugh acted as a magnet for some of his brother’s leading vassals, including the king’s constable (Walo of Chaumont-en-Vexin) and seneschal (Gilbert of Garlande). The Ile de France was well represented in Hugh’s entourage, including later William the Carpenter of Melun, Thomas of Marle and Drogo of Nesle. Capetian interest was not entirely ideological. Participation in the expedition was agreed during a council at Paris in February 1096; in July, Hugh’s participation was announced to the pope by King Philip with his own submission to Urban’s judgement over his adulterous marriage (to the wife of the count of Anjou, to whom Urban had presented a golden rose during his preaching tour in March). Thus Urban’s Jerusalem scheme produced immediate and direct political gains for the wider papal cause by allowing Philip to be reconciled without losing too much face. The settlement suited both sides, Hugh receiving a papal banner to carry on his pilgrimage. The numerous recruits from the Paris region indicate another political benefit, this time for the Capetians, by providing a rare opportunity to exhibit practical leadership over their unruly vassals of the Ile de France, although Hugh hardly proved a dominant figure.
His journey was carefully planned; before leaving, probably in late August, he wrote to Alexius I, informing him of his intended itinerary.27
This took him through Italy, where he may have received the papal banner and blessing, to Bari. By this time Hugh’s small contingent of knights had been swelled by the French lords from Emich of Flonheim’s misadventure led by William of Melun. In southern Italy, his party was joined by one of Bohemund’s nephews, William FitzMarquis, and others, including veterans of Byzantine service.28 Crossing the Adriatic in October, after the indignity of a shipwreck, Hugh was held under comfortable house-arrest in Durazzo by the nonetheless hospitable Greek authorities before being escorted under close guard to Constantinople. Alexius seemed concerned lest Hugh linked up with the large numbers of Italians following the same route along the Via Egnatia from Durrazzo to the capital; or he may have received warning that his old enemy Bohemund was only a fortnight behind the count. Hugh was welcomed at Constantinople in November, only a few weeks after the massacre at Kibotos. Alexius’s treatment of Hugh betrayed nervousness; although well entertained and apparently rather embarrassingly easily flattered by the emperor’s attention, the count’s movements were monitored and some of his followers kept under close arrest. The emperor was beginning to appreciate the scale of his problems. Almost every day, news came of more western grandees bearing down on him while the flow of lesser pilgrims became a flood, swelled by the bumper harvest experienced in the west in the autumn of 1096. Miraculous would not necessarily have been Alexius’s word for it.
