Patrick White, Tiery Wright, Louis Zindel, and Jacob Dodson, a free young
colored man of Washington city, who volunteered to accompany the
expedition, and performed his duty manfully throughout the voyage. Two
Delaware Indians--a fine-looking old man and his son--were engaged to
accompany the expedition as hunters, through the kindness of Major
Cummins, the excellent Indian agent. L. Maxwell, who had accompanied the
expedition as one of the hunters in 1842, being on his way to Taos, in New
Mexico, also joined us at this place.

The party was generally armed with Hall's carbines, which with a brass
twelve-pound howitzer, had been furnished to me from the United States
arsenal at St. Louis, agreeably to the orders of Colonel S.W. Kearney,
commanding the third military division. Three men were especially detailed
for the management of this piece, under the charge of Louis Zindel, a
native of Germany, who had been nineteen years a non-commissioned officer
of artillery in the Prussian army, and regularly instructed in the duties
of his profession. The camp equipage and provisions were transported in
twelve carts, drawn each by two mules; and a light covered wagon, mounted
on good springs, had been provided for the safer carriage of instruments.
