Rioting in Baltimore when the Mass. and Penna. Militias marched into (invaded) Maryland. Not low lifes, but businessmen were throwing bricks and cobblestones at the invading troops.
"Our men are not moles, and can't dig under the earth; they are not birds, and can't fly through the air. There is no way but to march across, and that they must do. But in doing this there is no need of collision. 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." A. Lincoln
