Maryland's legislature voted overwhelmingly (53–13) to stay in the Union, but also rejected hostilities with its southern neighbors, voting to close Maryland's rail lines to prevent them from being used for war.[121] Lincoln responded by establishing martial law and unilaterally suspending habeas corpus in Maryland, along with sending in militia units from the North.[122] Lincoln rapidly took control of Maryland and the District of Columbia by seizing many prominent figures, including arresting 1/3 of the members of the Maryland General Assembly on the day it reconvened.[121][123] All were held without trial, ignoring a ruling by the Chief Justice of the U.S. Supreme Court Roger Taney, a Maryland native, that only Congress (and not the president) could suspend habeas corpus (Ex parte Merryman). ./cache/en-wikipedia-org-1710.html ./txt/en-wikipedia-org-1710.txt
