Sioux Red Cloud's father had a brother who married a Northern Cheyenne woman about 1820, and the Cheyenne Red Cloud was their son. This indicates that the Northern Cheyennes and Ogallala Sioux were at peace and intermarrying at that time. This Red Cloud, half Sioux and half Northern Cheyenne, married a Southern Cheyenne woman, and lived with the Southern tribe. This would indicate peaceful and intermarrying relations between the north and south branches existed about 1840 or a little later. It might have been after the peace of 1840-1841.

This peace was brought about by Red Arm for the Cheyennes and Lone Horn for the Min-ne-con-jou Sioux (or the tribe of "shooters in the mist"). The Sioux and Arapahoes remained hostile for some time thereafter.

Among the oldest of the Cheyennes now living there are found those who say that Lone Horn was the first of all the Sioux to bring his band to the Platte river, and he did not live here. He came down to hunt, and to run the mustangs, for wild horses abounded in the valley of the North Platte river and adjoining territory.

Volume I of Wyoming historical publications, in an article on Fort Laramie says in 1835 two men were sent to the Black Hills to induce Bull Bear's Ogallalas to come to the Platte to live, and that this was the first Sioux band to come near Fort Laramie to trade.

There was no Fort Laramie then, and the

Fort William that was the antecedent of the historic fort was builded 1835. Lone Horn's hunting trips must have antedated that event by at least a score of years. The Sioux were here in numbers as early as 1815, for the battle of Kiowa with the Kiowas, and the Battle of Round House Rock, with the Pawnees, were about 1815.
