Meantime the garrison in Ostend were at their last gasp. On being asked by the States-General whether it was possible to hold out for twenty days longer, Marquette called a council of officers, who decided that they would do their best, but that it was impossible to fix a day or hour when resistance must cease. Obviously, however, the siege was in its extreme old age. The inevitable end was approaching. Before the middle of September the enemy was thoroughly established in possession of the new Hell's Mouth, the new Porcupine, and all the other bastions of the new entrenchment. On the 13th of that month the last supreme effort was made, and the Sand Hill, that all-important redoubt, which during these three dismal years had triumphantly resisted every assault, was at last carried by storm. The enemy had now gained possession of the whole town except Little Troy. The new harbour would be theirs in a few hours, and as for Troy itself, those hastily and flimsily constructed ramparts were not likely to justify the vaunts uttered when they were thrown up nor to hold out many minutes before the whole artillery of Spinola. Plainly on this last morsel of the fatal sandbank the word surrender must be spoken, unless the advancing trumpets of Maurice should now be heard. But there was no such welcome sound in the air. The weather was so persistently rainy and stormy that the roads became impassable, and Maurice, although ready and intending to march towards Spinola to offer him battle, was unable for some days to move. Meantime a council, summoned by Marquette, of all the officers, decided that Ostend must be abandoned now that Ostend had ceased to exist. On the 20th September the Accord was signed with Spinola. The garrison were to march out with their arms. They were to carry off four cannon but no powder. All clerical persons were to leave the place, with their goods and chattels. All prisoners taken on both sides during the siege were to be released. Burghers, sutlers, and others, to go whither they would, undisturbed. And thus the archdukes, after three years and seventy-seven days of siege, obtained their prize. Three thousand men, in good health, marched out of little Troy with the honours of war. The officers were entertained by Spinola and his comrades at a magnificent banquet, in recognition of the unexampled heroism with which the town had been defended. Subsequently the whole force marched to the headquarters of the States' army in and about Sluys. They were received by Prince Maurice, who stood bareheaded and surrounded by his most distinguished officers; to greet them and to shake them warmly by the hand. Surely no defeated garrison ever deserved more respect from friend or foe.
