I then proposed to spare you all except six companies, two of which were then in the Department of New Mexico, to be returned to Colorado. This proposition it was not thought prudent to accept, as you said it would not be prudent to weaken the frontier lines; but as we were then at peace with all of the tribes in this Territory and on the plains, I thought it possible to spare all the troops excepting the six companies.

Now we have but half the troops we then had, and are at war with a powerful combination of Indian tribes, who are pledged to sustain each other and drive the white people from this country. I was made aware of this combination last fall through reliable sources of information, which were at once sent to the Colorado District headquarters, and thence to department headquarters at Saint Louis, and to the Indian Bureau at Washington. They were, through the Secretary of the Interior, laid before the War Department. I also went to Washington last fall to make preparations for the probable conflict. I inclose copies of the more important papers referred to for you information, to which I made reference in a former letter. The Secretary of War asked me what I thought to be necessary, to which I replied that our troops, First Cavalry, ought to have carbines (as they were only armed with pistols and sabers), and that I desired the posts on the plains in Kansas and Nebraska to be strengthened as much as he could do by springtime. He promptly told me we should have the carbines, and they were accordingly to be sent out at once. They have arrived since the hostilities commenced this spring, having been detained on the way all winter by bad weather or other cause of delay.

Having no militia organization that is serviceable for other than neighborhood defenses, and they only in the more densely [populated] settlements, mostly in the mountains and on settlements that are exposed on the plains, being scattered along the streams, in single tiers of houses, from 2 to 4 miles apart for hundreds of miles along the South Platte and Arkansas Rivers and their tributaries, it is perfectly out of the question for them to be collected on the headwaters of the Republican and Smoky Hill Forks of the Kansas River. The depredations have commenced precisely as foretold in my communications to the Departments last fall. From information I have just received from old Indian traders and from Indians within a few days I feel assured that the Sioux Indians that reside in this Territory and the band of Arapahoes referred to have declined to join in the war as they were expected to do; but I have from the same sources of information, which I regard as reliable, learned that all of the Cheyennes, a most warlike and powerful tribe, with the Kiowas and Comanches, are allied and now carrying out their hellish purposes according to their agreement.

That they are in strong force on the plains I have no doubt, and if the U. S. troops are withdrawn I feel confident that they will wipe out our sparse settlements in spite of any home force we could muster against them. The troops have had several skirmishes with them, and at Cedar Canon Major Downing gave a party of them a severe chastisement; but what has been done, the traders who know them well say, has only whetted their appetite for revenge, and has by no means subdued them. Unless a force can be sent out to chastise this combination severely and at once the delay will cost us a
