Towards the west and southwest, externally, upon the territory of Flanders--not an inch of which belonged to the republic, save the sea- beaten corner in which nestled the little town-eighteen fortresses had been constructed by the archduke as a protection against hostile incursions from the place. Of these, the most considerable were St. Albert, often mentioned during the Nieuport campaign, St. Isabella St. Clara, and Great-Thirst. On the 5th July, 1601, the archduke came before the town, and formally began the siege. He established his headquarters in the fort which bore the name of his patron saint. Frederic van den Berg meanwhile occupied fort Breden on the eastern side, with the intention, if possible, of getting possession of the Gullet, or at least of rendering the entrance to that harbour impossible by means of his hostile demonstrations. Under Van den Berg was Count Bucquoy-Longueval, a Walloon officer of much energy and experience, now general-in-chief of artillery in the archduke's army. The numbers with which Albert took the field at first have not been accurately stated, but it is probable that his object was to keep as many as twenty thousand constantly engaged in the siege, and that in this regard he was generally successful. Within the town were fifty-nine companies of infantry, to which were soon added twenty-three more under command of young Chatillon, grandson of the great Coligny. It was "an olla podrida of nationalities," according to the diarist of the siege--[Meteren]. English, Scotch, Dutch, Flemings, Frenchmen, Germans, mixed in about equal proportions. Commander-in- chief at the outset was Sir Francis Vere, who established himself by the middle of July in the place, sent thither by order of the States-General. It had been the desire of that assembly that the stadholder should make another foray in Flanders for the purpose of driving off the archduke before he should have time to complete his preliminary operations. But for that year at least Maurice was resolved not to renounce his own schemes in deference to those so much more ignorant than himself of the art of war, even if Barneveld and his subordinates on their part had not learned a requisite lesson of modesty.
