Of the seven or eight thousand soldiers in the town when the siege began, at least two thousand were English. The queen, too intelligent, despite her shrewishness to the Staten; not to be faithful to the cause in which her own interests were quite as much involved as theirs, had promised Envoy Caron that although she was obliged to maintain twenty thousand men in Ireland to keep down the rebels, directly leagued as they were with Spain and the archdukes, the republic might depend upon five thousand soldiers from England. Detachment after detachment, the soldiers came as fast as the London prisons could be swept and the queen's press-gang perform its office. It may be imagined that the native land of those warriors was not inconsiderably benefited by the grant to the republic of the right to make and pay for these levies. But they had all red uniforms, and were as fit as other men to dig trenches, to defend them; and to fill them afterwards, and none could fight more manfully or plunder friend and foe with greater cheerfulness of impartiality than did those islanders. The problem which the archduke had set himself to solve was not an easy one. He was to reduce a town, which he could invest and had already succeeded very thoroughly in investing on the land aide, but which was open to the whole world by sea; while the besieged on their part could not only rely upon their own Government and people, who were more at home on the ocean than was any nation in the world, but upon their alliance with England, a State hardly inferior in maritime resources to the republic itself. On the western side, which was the weakest, his progress was from the beginning the more encouraging, and his batteries were soon able to make some impression upon the outer works, and even to do considerable damage to the interior of the town. In the course of a few months he had fifty siege-guns in position, and had constructed a practicable road all around the place, connecting his own fortifications on the west and south with those of Bucquoy on the east.
