Nothing could be more beautiful as a production of military art, nothing, to the general reader, more insipid than its details.

On the land side, Hohenlo's headquarters were at Ramsdonck, a village about a German mile to the east of Gertruydenberg. Maurice himself was established on the west side of the city. Two bridges constructed across the Donge facilitated the communications between the two camps, while great quantities of planks and brush were laid down across the swampy roads to make them passable for waggon-trains and artillery. The first care of the young general, whose force was not more than twenty thousand men, was to protect himself rather than to assail the town.

His lines extended many miles in a circuit around the place, and his forts, breastworks, and trenches were very numerous.

The river was made use of as a natural and almost impassable ditch of defence, and windmills were freely employed to pump water into the shallows in one direction, while in others the outer fields, in quarters whence a relieving force might be expected, were turned into lakes by the same machinery. Farther outside, a system of palisade work of caltrops and man-traps—sometimes in the slang of the day called Turkish ambassadors—made the country for miles around impenetrable or very disagreeable to cavally. In a shorter interval than would have seemed possible, the battlements and fortifications of the besieging army had risen like an exhalation out of the morass. The city of Gertruydenberg was encompassed by another city as extensive and apparently as impregnable as itself. Then, for the first time in that age, men thoroughly learned the meaning of that potent implement the spade.

Three thousand pioneers worked night and day with pickaxe and shovel. The soldiers liked the business; for every man so employed received his ten stivers a day additional wages, punctually paid, and felt moreover that every stroke was bringing the work nearer to its conclusion.

The Spaniards no longer railed at Maurice as a hedger and ditcher. When he had succeeded in bringing a hundred great guns to bear upon the beleaguered city they likewise ceased to sneer at heavy artillery.

The Kartowen and half Kartowen were no longer considered "espanta vellacos."

Meantime, from all the country round, the peasants flocked within the lines. Nowhere in Europe were provisions so plentiful and cheap as in the Dutch camp. Nowhere was a readier market for agricultural products, prompter payment, or more perfect security for the life and property of non-combatants. Not so much as a hen's egg was taken unlawfully. The country people found themselves more at ease within Maurice's lines than within any other part of the provinces, obedient or revolted. They ploughed and sowed and reaped at their pleasure, and no more striking example was ever afforded of the humanizing effect of science upon the barbarism of war, than in this siege of Gertruydenberg.

Certainly it was the intention of the prince to take his city, and when he fought the enemy it was his object to kill; but, as compared with the bloody work which Alva, and Romero, and Requesens, and so many others had done in those doomed provinces, such war-making as this seemed almost like an institution for beneficent and charitable purposes.

Visitors from the neighbourhood, from other provinces, from foreign countries, came to witness the extraordinary spectacle, and foreign generals repaired to the camp of Maurice to take practical lessons in the new art of war.
