After thinking it over Clark decided, as the less of two evils, to
follow the hazardous course of himself announcing his approach. He
trusted that the boldness of such a course, together with the shock of

treated as enemies. [Footnote: Clark's "Memoir."]

extract from what is called "Col. Clark's Journal." This is the official
report which he speaks of as being carried by William Moires, his
express, who was taken by the Indians (see his letter to Henry of April
29th; there seems, by the way, to be some doubt whether this letter was
