Andrew Johnson actually said...

"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"

"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"

"I therefore request that you will at once take such measures as will insure its safety, and thus discourage any attempt for its possession by insurgent or other illegal combinations."

"The Lieutenant-General will proceed to the execution of his duties without delay."
