The men who tried to lead Maryland into secession were not a solid set of die-hard slavery advocates. Slavery in Maryland was a moribund institution. A meeting in favor of secession, held April 18 in Baltimore's Taylor Hall, was chaired by T. Parkin Scott, who "was a strong sympathizer with the South," Brown wrote, "and had the courage of his convictions, but he had been also an opponent of slavery, and I have it from his own lips that years before the war, on a Fourth of July, he had persuaded his mother to liberate all her slaves, although she depended largely on their services for her support. And yet he lived and died a poor man." The federal government felt sufficiently unsure of Maryland's allegiance that it issued an April 27, 1861, order for the arrest and detention of anyone between Washington and Philadelphia who was suspected of subversive deeds or utterances, with its notorious suspension of habeas corpus. This led to the
Merryman case, and the Supreme Court's failure to get the authorities to enforce its rejection of the administration's move.
Hicks then called the legislature in the northwest part of the state, where unionism was strongest. Though the legislature did not vote to secede, it approved a resolution calling for "the peaceful and immediate recognition of the independence of the Confederate States," which Maryland "hereby gives her cordial consent thereunto, as a member of the Union." The legislature also denounced "the present military occupation of Maryland" as a "flagrant violation of the Constitution."
