He had, for a few weeks immediately succeeding the battle, distributed his troops in three different stations. On the approach of the Duke, however, he hastily concentrated his whole force at his own strongly fortified camp, within half cannon shot of Groningen. His army, such as it was, numbered from 10,000 to 12,000 men. Alva reached Groningen early in the morning, and without pausing a moment, marched his troops directly through the city. He then immediately occupied an entrenched and fortified house, from which it was easy to inflict damage upon the camp. This done, the Duke, with a few attendants, rode forward to reconnoitre the enemy in person. He found him in a well fortified position, having the river on his front, which served as a moat to his camp, and with a deep trench three hundred yards beyond, in addition. Two wooden bridges led across the river; each was commanded by a fortified house, in which was a provision of pine torches, ready at a moment's warning, to set fire to the bridges. Having thus satisfied himself, the Duke rode back to his army, which had received strict orders not to lift a finger till his return. He then despatched a small force of five hundred musketeers, under Robles, to skirmish with the enemy, and, if possible, to draw them from their trenches. The troops of Louis, however, showed no greediness to engage. On the contrary, it soon became evident that their dispositions were of an opposite tendency. The Count himself, not at that moment trusting his soldiery, who were in an extremely mutinous condition, was desirous of falling back before his formidable antagonist. The Duke, faithful, however, to his life-long principles, had no intentions of precipitating the action in those difficult and swampy regions. The skirmishing, therefore, continued for many hours, an additional force of 1000 men being detailed from the Spanish army. The day was very sultry, however, the enemy reluctant, and the whole action languid. At last, towards evening, a large body, tempted beyond their trenches, engaged warmly with the Spaniards. The combat lasted but a few minutes, the patriots were soon routed, and fled precipitately back to their camp. The panic spread with them, and the whole army was soon in retreat. On retiring, they had, however, set fire to the bridges, and thus secured an advantage at the outset of the chase. The Spaniards were no longer to be held. Vitelli obtained permission to follow with 2000 additional troops. The fifteen hundred who had already been engaged, charged furiously upon their retreating foes. Some dashed across the blazing bridges, with their garments and their very beards on fire. Others sprang into the river. Neither fire nor water could check the fierce pursuit. The cavalry dismounting, drove their horses into the stream, and clinging to their tails, pricked the horses forward with their lances. Having thus
