At the siege of Detroit, the Indians displayed a high degree of comparative steadiness and perseverance; and their history cannot furnish another instance of so large a force persisting so long in the attack of a fortified place. Their good conduct may be ascribed to their deep rage against the English, to their hope of speedy aid from the French, and to the controlling spirit of Pontiac, which held them to their work. The Indian is but ill qualified for such attempts, having too much caution for an assault by storm, and too little patience for a blockade. The Wyandots and Pottawattamies had shown, from the beginning, less zeal than the other nations; and now, like children, they began to tire of the task they had undertaken. A deputation of the Wyandots came to the fort, and begged for peace, which was granted them; but when the Pottawattamies came on the same errand, they insisted, as a preliminary, that some of their people, who were detained prisoners by the English, should first be given up. Gladwyn demanded, on his part, that the English captives known to be in their village should be brought to the fort, and three of them were accordingly produced. As these were but a small part of the whole, the deputies were sharply rebuked for their duplicity, and told to go back for the rest. They withdrew angry and mortified; but, on the following day, a fresh deputation of chiefs made their appearance, bringing with them six prisoners. Having repaired to the council-room, they were met by Gladwyn, attended only by one or two officers. The Indians detained in the fort were about to be given up, and a treaty concluded, when one of the prisoners declared that there were several others still remaining in the Pottawattamie village. Upon this, the conference was broken off, and the deputies ordered instantly to depart. On being thus a second time defeated, they were goaded to such a pitch of rage, that, as afterwards became known, they formed the desperate resolution of killing Gladwyn on the spot, and then making their escape in the best way they could; but, happily, at that moment the commandant observed an Ottawa among them, and, resolving to seize him, called upon the guard without to assist in doing so. A file of soldiers entered, and the chiefs, seeing it impossible to execute their design, withdrew from the fort, with black and sullen brows. A day or two afterwards, however, they returned with the rest of the prisoners, on which peace was granted them, and their people set at liberty.[241] CHAPTER XV. 1763. THE FIGHT OF BLOODY BRIDGE.
