Requesens, however, neither granted the release of the prisoners, nor permitted Mondragon to return. It was well for these prisoners, that Bossu was in the hands of the prince. Had it not been for this they would have all been put to death. With the fall of Middleburg the Dutch and Zeelanders remained masters of the entire line of sea coast, but on land the situation was still perilous. Leyden was closely invested, and all communications by land between the various cities suspended. The sole hope that remained was in the army raised by Count Louis. He had raised 3000 cavalry and 6000 infantry, and, accompanied by the prince's other two brothers, crossed the Rhine in a snowstorm and marched towards Maastricht. The Prince of Orange had on his part with the greatest difficulty raised 6000 infantry, and wrote to Count Louis to move to join him in the Isle of Bommel after he had reduced Maastricht. But the expedition, like those before it, was destined to failure. A thousand men deserted, seven hundred more were killed in a night surprise, and the rest were mutinous for their pay. Finally, Count Louis found himself confronted by a force somewhat inferior in numbers to his own. But the Spanish infantry were well disciplined and obedient, those of Louis were mercenaries and discontented; and although at first his cavalry gained an advantage, it was a short one, and after a fierce action his army was entirely defeated. Count Louis, finding that the day was lost, gathered a little band of troopers, and with his brother, Count Henry, and Christopher, son of the Elector Palatine, charged into the midst of the enemy. They were never heard of more. The battle terminated in a horrible butchery. At least 4000 men were either killed in the field, suffocated in the marshes, drowned in the river, or burned in the farmhouses in which they had taken refuge. Count Louis, and his brother and friend, probably fell on the field, but stripped of their clothing, disfigured by wounds and the trampling of horses, their bodies were never recognized. The defeat of the army and the death of his two brave brothers was a terrible blow to the Prince of Orange. He was indeed paying dear for his devotion to his country. His splendid fortune had been entirely spent, his life had been one of incessant toil and anxiety, his life had been several times threatened with assassination, he had seen his every plan thwarted. Save on the sandy slip of coast by the ocean, the whole of the Netherlands was still prostrate beneath the foot of the Spaniard; and now he had lost two of his brothers. England and France had alternately encouraged and stood aloof from him, and after all these efforts and sacrifices the prospects of ultimate success were gloomy in the extreme.
