The Catholic general had concealed his design in a masterly manner. He had detained Maurice in the isle of Cadzand, the States still dreaming of a victorious invasion on their part of obedient Flanders, and the stadholder hesitating to quit his position of inactive observation, lest the moment his back was turned the rapid Spinola might whirl down upon Sluys, that most precious and skilfully acquired possession of the republic, when lo! his formidable antagonist was marching in force upon what the prince well knew to be her most important and least guarded frontier. On the 8th August the Catholic general was before Olden-zaal which he took in three days, and then advanced to Lingen. Should that place fall --and the city was known to be most inadequately garrisoned and supplied --it would be easy for the foe to reduce Coeworden, and so seize the famous pass over the Bourtanger Morass, march straight to Embden--then in a state of municipal revolution on account of the chronic feuds between its counts and the population, and therefore an easy prey--after which all Friesland and Groningen would be at his mercy, and his road open to Holland and Utrecht; in short, into the very bowels of the republic. On the 4th August Maurice broke up his camp in Flanders, and leaving five thousand men under Colonel Van der Noot, to guard the positions there, advanced rapidly to Deventer, with the intention of saving Lingen. It was too late. That very important place had been culpably neglected. The garrison consisted of but one cannoneer, and he had but one arm. A burgher guard, numbering about three hundred, made such resistance as they could, and the one-armed warrior fired a shot or two from a rusty old demi-cannon. Such opposition to the accomplished Italian was naturally not very effective. On the 18th August the place capitulated. Maurice, arriving at Deventer, and being now strengthened by his cousin Lewis William with such garrison troops as could be collected, learned the mortifying news with sentiments almost akin to despair. It was now to be a race for Coeworden, and the fleet-footed Spinola was a day's march at least in advance of his competitor. The key to the fatal morass would soon be in his hands. To the inexpressible joy of the stadholder, the Genoese seemed suddenly struck with blindness. The prize was almost in his hands and he threw away all his advantages. Instead of darting at once upon Coeworden he paused for nearly a month, during which period he seemed intoxicated with a success so rapidly achieved, and especially with his adroitness in outwitting the great stadholder. On the 14th September he made a retrograde movement towards the Rhine, leaving two thousand five hundred men in Lingen. Maurice, giving profound thanks to God for his enemy's infatuation, passed by Lingen, and having now, with his cousin's reinforcements, a force of nine thousand foot and three
