HUNTSVILLE, MO., February 25, 1865.

Lieutenant W. T. CLARKE,

Acting Assistant Adjutant-General, Macon:

Commencing at Fort Union, the farthest post I occupy, I have stationed one company of the Thirtieth Wisconsin which I had to leave there to guard the stores sent up the river to establish a four-company post up the Yellowstone; there being no water in the Yellowstone that season prevented the establishing of the post.
