After the battle, the brigade of Milton Sublette, together with the
free trappers, and Wyeth's New England band, remained some days at the
rendezvous, to see if the main body of Blackfeet intended to make an
attack; nothing of the kind occurring, they once more put themselves
in motion, and proceeded on their route toward the southwest. Captain
Sublette having distributed his supplies, had intended to set off on
his return to St. Louis, taking with him the peltries collected from
the trappers and Indians. His wound, however obliged him to postpone his
departure. Several who were to have accompanied him became impatient of
this delay. Among these was a young Bostonian, Mr. Joseph More, one of
the followers of Mr. Wyeth, who had seen enough of mountain life and
savage warfare, and was eager to return to the abodes of civilization.
He and six others, among whom were a Mr. Foy, of Mississippi, Mr. Alfred
K. Stephens, of St. Louis, and two grandsons of the celebrated Daniel
Boon, set out together, in advance of Sublette's party, thinking they
would make their way through the mountains.

It was just five days after the battle of the swamp that these seven
companions were making their way through Jackson's Hole, a valley not
far from the three Tetons, when, as they were descending a hill, a party
of Blackfeet that lay in ambush started up with terrific yells. The
horse of the young Bostonian, who was in front, wheeled round with
affright, and threw his unskilled rider. The young man scrambled up
the side of the hill, but, unaccustomed to such wild scenes, lost his
presence of mind, and stood, as if paralyzed, on the edge of a bank,
until the Blackfeet came up and slew him on the spot. His comrades had
fled on the first alarm; but two of them, Foy and Stephens, seeing
his danger, paused when they got half way up the hill, turned back,
dismounted, and hastened to his assistance. Foy was instantly killed.
