71 Perhaps the reason for Sibley's tampering with Indians in Spanish
Territory was that he was pursuing instructions sent to him in 1805.
He was to use all means at all times to conciliate Indians, who, in case
of a rupture with Spain, would be "either useful or mischievous to the
United States," and to direct his attentions to Texas Indians as far as
San Bernardo Bay. Secretary of War to John Sibley, May 25, July 8, 1805,
