It is not my purpose to describe in detail the scientific operations during the sixty-five days between the 20th May and the 24th July. Again the commander-in-chief enlightened the world by an exhibition of a more artistic and humane style of warfare than previously to his appearance on the military stage had been known. But the daily phenomena of the Leaguer--although they have been minutely preserved by most competent eyewitnesses--are hardly entitled to a place except in special military histories where, however, they should claim the foremost rank. The fortifications of the city were of the most splendid and substantial character known to the age. The ditches, the ravelins, the curtains, the towers were as thoroughly constructed as the defences of any place in Europe. It was therefore necessary that Maurice and his cousin Lewis should employ all their learning, all their skill, and their best artillery to reduce this great capital of the Eastern Netherlands. Again the scientific coil of approaches wound itself around and around the doomed stronghold; again were constructed the galleries, the covered ways, the hidden mines, where soldiers, transformed to gnomes, burrowed and fought within the bowels of the earth; again that fatal letter Y advanced slowly under ground, stretching its deadly prongs nearer and nearer up to the walls; and again the system of defences against a relieving force was so perfectly established that Verdugo or Mansfield, with what troops they could muster, seemed as powerless as the pewter soldiers with which Maurice in his boyhood--not yet so long passed away --was wont to puzzle over the problems which now practically engaged his early manhood. Again, too, strangely enough, it is recorded that Philip Nassau, at almost the same period of the siege as in that of Gertruydenberg, signalized himself by a deed of drunken and superfluous daring. This time the dinner party was at the quarters of Count Solms, in honour of the Prince of Anhalt, where, after potations pottle deep, Count Philip rushed from the dinner-table to the breach, not yet thoroughly practicable, of the north ravelin, and, entirely without armour, mounted pike in hand to the assault, proposing to carry the fort by his own unaided exertions. Another officer, one Captain Vaillant, still more beside himself than was the count, inspired him to these deeds of valour by assuring him that the mine was to be sprung under the ravelin that afternoon, and that it was a plot on the part of the Holland boatmen to prevent the soldiers who had been working so hard and so long in the mines from taking part in the honours of the assault. The count was with difficulty brought off with a whole skin and put to bed. Yet despite these disgraceful pranks there is no doubt that a better and braver officer than he was hardly to be found even among the ten noble Nassaus who at that moment were fighting for the cause of Dutch liberty--
