    Notes:

    Constable of Flanders.

    "As constable of Flanders, Gilles accompanied Baudouin VI-IX, Graaf van Henegouwen to the Fourth Crusade. However he chose a separate route, crossing France and Italy. Arriving in Piacenza, he found Baudouin's messengers who pressed him to join Baudouin in Venice. However Gilles preferred to embark at Brindisi and go directly to the Holy Land. The crusader and chronicler Geoffroi I de Villehardouin describes Gilles' decision as a defection; it was poorly received by Baudouin and especially by Enrico Dandolo, the doge of Venice, who used it to refuse credit to the Crusaders and demanded of them that they pay the Venetian fleet in kind by capturing the Byzantine city of Zara. The defection of the Constable of Flanders was one of the first steps down the road that eventually led to the capture of Constantinople by the Crusaders in 1204, and to Baudouin becoming emperor of Constantinople that year. Gilles was killed in 1204 by the Turkomans in a battle at Riblah on the Orontes as he was going to the aid of Boemund IV, prince of Antioch, probably against Leo I, king of Armenia."

    Notes:

    "In 1186 Otton went on pilgrimage to the Holy Land, and in 1187 he brought back a piece purporting to be of the True Cross, that he offered to the abbey of Floreffe (the splendid reliquary made for it is in the Louvre. Another tradition claims that he brought back with him the design for windmills. In 1189 he left on crusade (probably with Philippe, count of Flanders) to recapture Jerusalem, which had been taken by Saladin after the Battle of Hattin in 1187. He fought between Jaffa and Ascalon on 6 November 1291 and was helped by Richard the Lionheart himself. In April 1192 he was appointed, with Henri II, comte de Champagne and Guillaume Cayeux, to offer the crown of Jerusalem to Conrad, marchese de Monferrato. However Conrad was assassinated on 26 April, and on 5 May Otton attended the wedding of Conrad's widow Isabella d'Anjou, queen of Jerusalem, and Henri II, comte de Champagne, who became king of Jerusalem by right of his wife. Otton died later that year, probably killed in the siege of Acre." [Leo van de Pas, citation details below.]
