done by Po-li-ni's band. Captain R. S. Caldwell with his company and a detachment of infantry has been ordered to the South Fork of John Day's River for the protection of the road. A company of forty men (mounted) is being raised at The Dalles for the same service. If you should deem it advisable, the general authorizes you after your return from Harney Lake to move your depot to the South Fork. This movement is left entirely to your discretion. The general is averse to interrupting the original plan of operations unless absolutely requisite for the protection of the settlements. This information is given in order that you may know what is taking place in your rear.

I am, very respectfully, your obedient servant,

Asst. Adjt. General, Hdqrs. Dept. of the Pacific, San Francisco, Cal.:

William Wood, First Washington Territory Infantry, left this post for Fort Dalles, thence to take post at the South Fork of John Day's River on the road from Dalles to Canyon City.

I have to report that I received on the 25th a telegram dated the 24th, from General Wright, commanding the department, saying, "You can accept the detachment of cavalry. Muster in by one of your own officers. Particulars by mail.

I have ordered Captain W. V. Spencer, assistant commissary of musters, to muster in Nathan Olney, esq., as second lieutenant and recruiting officer to raise the detachment. He was appointed by the Governor of Oregon. When it is raised Captain Spencer will
