WASHINGTON CITY, D. C. December 21, 1861
Honorable WILLIAM H. SEWARD, Secretary of State.
SIR: To-day I was arrested and am now confined in the Old Capitol as a prisoner of stae. Since coming here I have received intelligence that a secession flag was found in my trunk. I deem it prudent to make the following statement in order that the matter may be made to establish their own govenrmet I was at Irving College Manchester, Md. A number of the students requested me to make a flag in order that it might be displayed to the public. I complied with their request, made the flag and hoisted the flag in the campus. The president of the college ordered me to take it down. I obeyed and since that ime since. M. Thompson saw it but once and then he ordered me to destroy it. It was a relic to me and I refused to obey. He doubtless supposed I had destroyed it. I never intended to use the flag for any rebellious purposes. I am, sir, perfectfly willing to make oath to the above statement if need be.
Trusting that your honor may promptly receive and duly weigh this statement, I remain your very humble servant,
LEWIS LINN McARTHUR.
