"The Knight of the Rueful Countenance," Adalbert J. Volck, 1862


One of the most controversial acts of Lincoln’s presidency occurred two weeks after the war began when he suspended the writ of habeas corpus in Maryland, effectively imposing martial law in that state. Lincoln was responding to repeated attacks on railroad bridges that threatened lines of supply and communication between Washington, D.C., and the North but his action upset many Americans, including Adalbert Volk of Baltimore, a southern sympathizer who created a series of satirical cartoons deriding the president.
