HEADQUARTERS DISTRICT OF NEBRASKA,
Omaha, October 5, 1864.

Major- General CURTIS,

Commanding Department of Kansas, Fort Leavenworth:

I have just arrived fromthe west. I have troops stationed every fifteen miles from Plum Creek to Julesburg. There is no trouble to run coaches through with a little care. Guards are furnished all coaches that desire them as far as Julesburg. The attack on the 29th was evidently made by white men on a train from Bannock, which was transporting a large amount of gold. I will furnish you a full report of my campaign after leaving you at an early day.

Brigadier-General.
