This greatly exasperated the French, who kept a guard over the other Indians who were in town, and next day sent them to the woods. Then their head men, magistrates, and officers of the militia, summoned the Americans before a council, and ordered all who had not regular passports from the local court to leave at once, "bag and baggage." This created the utmost consternation among the Americans, whom the French outnumbered five to one, while the savages certainly would have destroyed them had they tried to go back to Kentucky. Their leaders again wrote urgent appeals for help to Clark, asking that a general guard might be sent them if only to take them out of the country. Filson had already gone overland to Louisville and told the authorities of the straits of their brethren at Vincennes, and immediately an expedition was sent to their relief under Captains Hardin and Patton. Indians Attempt to Destroy Americans. Meanwhile, on July 15th, a large band of several hundred Indians, bearing red and white flags, came down the river in forty-seven canoes to attack the Americans at Vincennes, sending word to the French that if they remained neutral they would not be molested. The French sent envoys to dissuade them from their purpose, but the war chiefs and sachems answered that the red people were at last united in opposition to "the men wearing hats," and gave a belt of black wampum to the wavering Piankeshaws, warning them that all Indians who refused to join against the whites would thenceforth be treated as foes. However, their deeds by no means corresponded with their threats. Next day they assailed the American block-house or stockaded fort, but found they could make no impression and drew off. They burned a few outlying cabins and slaughtered many head of cattle, belonging both to the Americans and the French; and then, seeing the French under arms, held further parley with them, and retreated, to the relief of all the inhabitants. A Successful Skirmish.
