From Saint Trond, in the neighbourhood of which he had remained several days, he advanced in a southerly direction towards Jodoigne. Count de Genlis, with a reinforcement of French Huguenots, for which the Prince had been waiting, had penetrated through the Ardennes, crossed the Meuse at Charlemont, and was now intending a junction with him at Waveron. The river Geta flowed between them. The Prince stationed a considerable force upon a hill near the stream to protect the passage, and then proceeded leisurely to send his army across the river. Count Hoogstraaten, with the rear-guard, consisting of about three thousand men, were alone left upon the hither bank, in order to provoke or to tempt the enemy, who, as usual, was encamped very near. Alva refused to attack the main army, but Frederic with a force of four thousand men, were alone left on the hither bank, in order to provoke or to tempt the enemy, who as usual, was encamped very near. Alva refused to attack the main army but rapidly detached his son, Don Fredrick, with a force of four thousand foot and three thousand horse, to cut off the rear-guard. The movement was effected in a masterly manner, the hill was taken, the three thousand troops which had not passed the river were cut to pieces, and Vitelli hastily despatched a gentleman named Barberini to implore the Duke to advance with the main body, cross the river, and, once for all, exterminate the rebels in a general combat. Alva, inflamed, not with ardor for an impending triumph, but with rage, that his sagely-conceived plans could not be comprehended even by his son and by his favorite officers, answered the eager messenger with peremptory violence. "Go back to Vitelli," he cried. "Is he, or am I, to command in this campaign? Tell him not to suffer a single man to cross the river. Warn him against sending any more envoys to advise a battle; for should you or any other man dare to bring me another such message, I swear to you, by the head of the King, that you go not hence alive."
