HEADQUARTERS, Balitmore, January 24, 1862.

Hon. WILLIAM H. SEWARD, Secretary of State.

SIR: Nineteen persons were arrested last week at a place of rendezvous from which they were to go t othe insurgent States. Several haveb een released on taking the oath of allgiance, the evidence not being perfectly clear in regard to them. There are twelve who should be sent away as there is no room for them at Fort McHenry. One of these men, Thomas C. Titzpatrick, is claimed to be a British subject, and I am told was discharged from Fort Warren or Fort Lafayette on the application of Lord Lyons. I do not know what was the charge in recruiting for the insurgent army and that he was the leader of the party arrested. They were under on oath not to divulge the purposes of their organization.

I am, very respectfully, your obedient servant,
JOHN A. DIX,

Major-General.
