Meantime the two cousins, who directed all the military operations in the provinces, understood each other thoroughly and proceeded to perfect their new system, to be adopted at a later period by all civilized nations.
The regular army of the Netherlands was small in number at that moment--not more than twenty thousand foot with two thousand horse--but it was well disciplined, well equipped, and, what was of great importance, regularly paid.

Old campaigners complained that in the halcyon days of paper enrolments, a captain could earn more out of his company than a colonel now received for his whole regiment.

The days when a thousand men were paid for, with a couple of hundred in the field, were passing away for the United Provinces and existed only for Italians and Spaniards.

While, therefore, mutiny on an organised and extensive scale seemed almost the normal condition of the unpaid legions of Philip, the little army of Maurice was becoming the model for Europe to imitate.
The United Provinces were as yet very far from being masters of their own territory.

Many of their most important cities still held for the king.
In Brabant, such towns as Breda with its many dependencies and Gertruydenberg; on the Waal, the strong and wealthy Nymegen which Martin Schenk had perished in attempting to surprise; on the Yssel, the thriving city of Zutphen, whose fort had been surrendered by the traitor York, and the stately Deventer, which had been placed in Philip's possession by the treachery of Sir William Stanley; on the borders of Drenthe, the almost impregnable Koevorden, key to the whole Zwollian country; and in the very heart of ancient Netherland, Groningen, capital of the province of the same name, which the treason of Renneberg had sold to the Spanish tyrant; all these flourishing cities and indispensable strongholds were garrisoned by foreign troops, making the idea of Dutch independence a delusion.
While Alexander of Parma, sorely against his will and in obedience to what, he deemed the insane suggestions of his master, was turning his back on the Netherlands in order to relieve Paris, now hard pressed by the Bearnese, an opportunity offered itself of making at least a beginning in the great enterprise of recovering these most valuable possessions.
The fair and pleasant city of Breda lies on the Merk, a slender stream, navigable for small vessels, which finds its way to the sea through the great canal of the Dintel.
