Ottawas and Canadians, who had come from Vincennes early in January,
when the weather was severe and the travelling fairly good. [Footnote:
Haldimand MSS. Hamilton's letter January 24, 1779.] He was at the time
on his way to Cahokia, to arrange for the defence; several of the
wealthier Frenchmen were with him in "chairs"--presumably creaking
wooden carts,--and one of them "swampt," or mired down, only a hundred
yards from the ambush. Clark and his guards were so on the alert that no
attack was made.

Clark Receives News concerning Vincennes.

In the midst of his doubt and uncertainty he received some news that
enabled him immediately to decide on the proper course to follow. He had
secured great influence over the bolder, and therefore the leading,
spirits among the French. One of these was a certain Francis Vigo, a
trader in St. Louis. He was by birth an Italian, who had come to New
Orleans in a Spanish regiment, and having procured his discharge, had
drifted to the creole villages of the frontier, being fascinated by the
profitable adventures of the Indian trade. Journeying to Vincennes, he
was thrown into prison by Hamilton; on being released, he returned to
St. Louis. Thence he instantly crossed over to Kaskaskia, on January 27,
1779, [Footnote: State Department MSS. Letters to Washington, 33, p.
90.] and told Clark that Hamilton had at the time only eighty men in
garrison, with three pieces of cannon and some swivels mounted, but that
as soon as the winter broke, he intended to gather a very large force
and take the offensive. [Footnote: State Department MSS. Papers of
Continental Congress, No. 71, Vol. I., p. 267.]

Clark Determines to Strike the First Blow.
