Hon. EDWIN M. STANTON,
Secretary of War.
Sir: There is ground to apprehend danger of an insurrection in Baltimore against the constituted authorities of the State of Maryland on or about the day of the election soon to be held in that city, and that in such contingency the aid of the United States might be invoked under the acts of Congress which pertain to that subject. While I am averse to any military demonstration that would have a tendency to interfere with the free exercise of the elective franchise in Baltimore or be construed into any interference in local questions, I feel great solicitude that should an insurrection take place the Government should be prepared to meet and promptly put it down. I accordingly desire you to call General Grant's attention to the subject, leaving to his own discretion and judgment the measures of preparation and precaution that should be adopted.
Very respectfully, yours,
