MONOCACY BRIDGE, August 10, 1864.

Major-General WALLACE:

The only troops at Relay House that can be used to relieve the New Jersey men are the Ninety-third New York. Shall I directed them to garrison the fort or send a company from here? Rumors of rebels, but our scouts have seen none for past two days. Will you send the two companies of Eleventh Maryland now in Baltimore to Monrovia? I think that post should be strengthened. I will name an officer to-morrow for Twelfth Maryland. They should be stationed at Hood's Mill.

E. B. TYLER,

Brigadier-General.

BALTIMORE, August 10, 1864.

Brigadier General E. B. TYLER,

Monocacy Bridg, Baltimore and Ohio Railroad:

If you can spare a company send it to Fort Dix; if not, put in some of the Ninety-third New York, and send a content officer to command. Will try and send you the two companies of the Eleventh Maryland. The Twelfth Maryland is nearly ready to move.

By command, &c.:

SAML. B. LAWRENCE,

Assistant Adjutant-General.
