On leave obtained from the prince, these two champions, the Englishman and the Hollander, spurred their horses through the narrow pass, with the waters up to the saddle-bow, at the head of a mere handful of troopers, not more than a dozen men in all. Two hundred musketeers followed, picking their way across the planks. As they emerged into the open country beyond, the Spanish soldiers guarding the passage fled without firing a shot. Such was already the discouraging effect produced upon veterans by the unexpected order given that morning to retreat. Vere and Bax sent word for all the cavalry to advance at once, and meantime hovered about the rearguard of the retreating enemy, ready to charge upon him so soon as they should be strong enough. Maurice lost no time in plunging with his whole mounted force through the watery defile; directing the infantry to follow as fast as practicable. When the commander-in-chief with his eight hundred horsemen, Englishmen, Zeelanders, Hollanders, and Germans, came upon the heath, the position and purpose of the enemy were plainly visible. He was not drawn up in battle order, waiting to sweep down upon his rash assailants so soon as, after struggling through the difficult pass, they should be delivered into his hands. On the contrary, it was obvious at a glance that his object was still to escape. The heath of Tiel, on which Spaniards, Italians, Walloons, Germans, Dutchmen, English; Scotch, and Irishmen now all found themselves together, was a ridgy, spongy expanse of country, bordered on one side by the swollen river, here flowing again through steeper banks which were overgrown with alders and pollard willows. Along the left of the Spanish army, as they moved in the direction of Herenthals, was a continuous fringe of scrub-oaks, intermixed with tall beeches, skirting the heath, and forming a leafless but almost impervious screen for the movements of small detachments of troops. Quite at the termination of the open apace, these thickets becoming closely crowded, overhung another extremely narrow passage, which formed the only outlet from the plain. Thus the heath of Tiel, upon that winter's morning, had but a single entrance and a single exit, each very dangerous or very fortunate for those capable of taking or neglecting the advantages offered by the position.
