In Rockville, Maryland Unionists meet to denounce the bill to abolish slavery in the District of Columbia
According to press reports, a large gathering of Montgomery County, Maryland men loyal to the Union met in Rockville to decry the U.S. Senate's passage four days before of the bill for the abolition of slavery in the District of Columbia. After speeches on the topic, a resolution passed unanimously calling on President Lincoln "to interpose his veto and protect the rights of property" should the House vote similarly in the upcoming week. The House did pass the measure on April 11, 1862 and Lincoln signed it into law five days later. (By John Osborne)
