FORT RILEY, August 27, 1865.

Major J. W. BARNES,

Assistant Adjutant-General:

In accordance with instructions of the 23rd instant, I have designated for muster out the Eleventh Indiana Cavalry Volunteers, numbering about 30 officers and 732 men, and Companies C, D, and G, of the Second Cavalry Colorado Volunteers, numbering eight officers and ninety enlisted men, all having from six to ten months' pay due. The necessary orders have been issued, but it will be ten to fifteen days before they arrive, as it will take a few days to relieve the different detachments. Colonel Maynadier, Fifth U. S. Volunteer Infantry, started for Fort Kearny yesterday with six companies of his regiment-all that were here. Major Curtis and Captain Moses, Second Colorado Cavalry, have been ordered to Fort Leavenworth as directed, and will start to-morrow.
