In the latter part of the month (May) a regimental band was formed, and Seidel, Eberdt, and Jakobi were detailed as members of it. J. J. Mueller and Reimers rejoined on the 5th. Detert was detailed as regimental pioneer on the 15th. The expedition being ready, those sick and unable to travel were left behind at Camp Pope; of Company E, Hellmann and Paul Paulson remained there. The strength of the company present at this time was 68, and aggregate number 85.
The second expedition for the chastisement of the Dakotas left Camp Pope on the 16th of June, 1863. The 19th and 21st of the month were spent in camp. On the 23rd, transportation permitting, the knapsacks of the men were carried in wagons. The valley between Big Stone Lake and Lake Traverse was reached on the 26th, and a camp established about a mile from the latter on the south side of the Minnesota River (there but a rivulet), which camp was situated near but outside of the state boundary. The camp was called McLaren, and three days were spent there. From here a detachment consisting of three companies of infantry, including Company H of the Sixth Regiment, some cavalry, and one piece of artillery, all under command of Lieutenant Colonel Averill, was dispatched to Fort Abercrombie for supplies. Klinghammer, unable to march, was sent along to the fort. It may be here noted, as a matter of interest to hydrographers, that Lake Traverse was not at this time an unbroken sheet of water, as a corporal of Company G crossed it on foot near the middle, seeing the lake in two parts, to the right and left of him.
Resumed the march on June 30th, and forded the Sheyenne River on the 4th of July, camping a little beyond it at a spot three-quarters of a mile northeast of the two mounds called "The Bowshot" and in the neighborhood of where the fight occurred about forty years before between the Pawnees, Shawnees, and Sheyennes, which, as I am informed, resulted in the annihilation of the last-named tribe. At this place,--named Camp Hayes,--70 miles distant from Camp McLaren, the expedition lay six days, awaiting the supply train, which arrived on the 9th. Resumed the march on the 11th, on which day Lieutenant Exel left on furlough. The 12th was spent in camp. The second crossing of the Sheyenne was made on the 17th. On the 18th arrived at two lakes named Jessie[2] and Leda, 90 miles from Camp Hayes. An entrenched camp was established on the banks of the former (the more easterly one of these two lakes) which was about three miles long. The camp was called Atchison, and a day and one-half were spent there in making arrangements for a vigorous pursuit of the Indians. Companies C and G of the Sixth were stationed there as a part of the garrison, and five of the company were left behind there, viz.: Seidel, Eberdt, and Jakobi, as members of the band, and Kraemer and Reuter, who were too sick to travel.
