Retaliation of the Frontiersmen. Outrages of this kind, continually happening alike to Americans and to Creoles under American protection, could not have been tamely borne by any self-respecting people. The fierce and hardy frontiersmen were goaded to anger by them, and were ready to take part in, or at least to connive at, any piece of lawless retaliation. Such an act of revenge was committed by Clark at Vincennes, as one result of his ill-starred expedition against the Wabash Indians in 1786. As already said, when his men mutinied and refused to march against the Indians, most of them returned home; but he kept enough to garrison the Vincennes fort. Unpaid, and under no regular authority, these men plundered the French inhabitants and were a terror to the peaceable, as well as to the lawless, Indians. Doubtless Clark desired to hold them in readiness as much for a raid on the Spanish possessions as for a defence against the Indians. Nevertheless they did some service in preventing any actual assault on the place by the latter, while they prevented any possible uprising by the French, though the harassed Creoles, under this added burden of military lawlessness, in many instances accepted the offers made them by the Spaniards and passed over to the French villages on the west side of the Mississippi. Clark Seizes a Spanish Boat. Before Clark left Vincennes, he summoned a court of his militia officers, and got them to sanction the seizure of a boat loaded with valuable goods, the property of a Creole trader from the Spanish possessions. The avowed reason for this act was revenge for the wrongs perpetrated in like manner by the Spaniards on the American traders; and this doubtless was the controlling motive in Clark's mind; but it was also true that the goods thus confiscated were of great service to Clark in paying his mutinous and irregularly employed troops, and that this fact, too, had influence with him.
