Days after the Baltimore riots against Massachusetts and Pennsylvania militia on April 19, 1861, Lincoln replied to members of a delegation from Baltimore who insisted he should do nothing. Lincoln said:

“You, gentlemen, come here to me and ask for peace on any terms, and yet have no word of condemnation for those who are making war on us. You express great horror of bloodshed, and yet would not lay a straw in the way of those who are organizing in Virginia and elsewhere to capture this city.

“The rebels attack Fort Sumter, and your citizens attack troops sent to the defense of the Government, and the lives and property in Washington, and yet you would have me break my oath and surrender the Government without a blow. There is no Washington in that, no Jackson in that, no manhood nor honor in that. … Keep your rowdies in Baltimore, and there will be no bloodshed. Go home and tell your people that if they will not attack us, we will not attack them; but if they do attack us, we will return it, and that severely.”
