Of this last act of treason the outcome was death. Surprised by the imperial forces at Andernach, on the Rhine, and hemmed in on all sides, he made his horse plunge into the water, hoping to reach the further bank and so make his escape, but the current was too strong for him, and horse and rider were swept away. Thus died Duke Giselbert (939), and at his death the star of his house for a while waned. His only son, an infant whom Otho placed under ward, died shortly afterwards, and though his nephew, Régnier III. of Hainault, seized his widow's dower, he was not strong enough to grasp the reins of government, and presently the Emperor Otho conferred the duchy on Conrad the Red, a native of Franconia, who, like his predecessor, was allied by marriage to the imperial house (944). Conrad was an energetic and capable man, but rude, passionate, vindictive, and, as the issue showed, untrustworthy. At first, however, all went well: the new duke rigidly enforced order, any attempt at rebellion he crushed with an iron hand, and for some ten years the land had peace; and then, having taken it into his head that Otho had treated him badly, he himself turned rebel. Whereat Régnier of Hainault, and the rest who had experienced Conrad's lash, taking heart, banded together against him and drove him from their midst (953). If Régnier believed that the Emperor would recompense his services by restoring him to the throne of his ancestors, he was doomed to signal disappointment. Otho was in no way deceived by the specious loyalty of his Lotharingian vassals. He knew very well that, in helping him to crush Conrad, they had in reality made him the instrument of their vengeance against one whom they hated, not on account of his recent rebellion, but because of his zeal for law and order and his former loyal service, and he refused to reward these lawless men by setting over them a chief as lawless as themselves, and one too, who, by reason of his popularity, would have all the more power to work mischief; nor would he confer the duchy on another German vassal, for such would be not unlikely to follow the example of Conrad. Henceforth he would govern Lotharingia by means of the Church.
