WASHINGTON CITY, March 11, 1861.

Honorable SIMON CAMERON, Secretary of War.

DEAR SIR: Our friends in Saint Louis desire that Captain Lyon may have the command of the troops at the Saint Louis Arsenal, and be charged with its defense, and that Major Hagner be required simply to take charge of the ordnance department. Captain Lyon ranks Major Hagner and would have command of the troops except for the fact that Major Hagner is assigned to duty according to his brevet rank. I ask in behalf of our friends that this assignment may be rescinded and the command of the troops given to Captain Lyon.

Respectfully,

FRANK P. BLAIR.
