Those measures were taken with the precision and promptness which marked the Duke's character, when precision and promptness were desirable. There had been a terrible energy in his every step, since the successful foray of Louis Nassau. Having determined to take the field in person with nearly all the Spanish veterans, he had at once acted upon the necessity of making the capital secure, after his back should be turned. It was impossible to leave three thousand choice troops to guard Count Egmont. A less number seemed insufficient to prevent a rescue. He had, therefore, no longer delayed the chastisement which had already been determined, but which the events in the north had precipitated. Thus the only positive result of Louis Nassau's victory was the execution of his imprisoned friends. The expedition under Aremberg had failed from two causes. The Spanish force had been inadequate, and they had attacked the enemy at a disadvantage. The imprudent attack was the result of the contempt with which they had regarded their antagonist. These errors were not to be repeated. Alva ordered Count Meghem, now commanding in the province of Groningen, on no account to hazard hostilities until the game was sure. He also immediately ordered large reinforcements to move forward to the seat of war. The commanders intrusted with this duty were Duke Eric of Brunswick, Chiappin Vitelli, Noircarmes, and Count de Roeulx. The rendezvous for the whole force was Deventer, and here they all arrived on the 10th July. On the same day the Duke of Alva himself entered Deventer, to take command in person. On the evening of the 14th July he reached Rolden, a village three leagues distant from Groningen, at the head of three terzios of Spanish infantry, three companies of light horse, and a troop of dragoons. His whole force in and about Groningen amounted to fifteen thousand choice troops besides a large but uncertain number of less disciplined soldiery. Meantime, Louis of Nassau, since his victory, had accomplished nothing. For this inactivity there was one sufficient excuse, the total want of funds. His only revenue was the amount of black mail which he was able to levy upon the inhabitants of the province. He repeated his determination to treat them all as enemies, unless they furnished him with the means of expelling their tyrants from the country. He obtained small sums in this manner from time to time. The inhabitants were favorably disposed, but they were timid and despairing. They saw no clear way towards the accomplishment of the result concerning which Louis was so confident. They knew that the terrible Alva was already on his way. They felt sure of being pillaged by both parties, and of being hanged as rebels, besides, as soon as the Governor-general should make his appearance.
