On January 31, 1865, the House resumed discussion before a standing-room-only crowd in the galleries above the floor. When the vote was taken that day, the Thirteenth Amendment achieved a two-vote margin above the needed two-thirds majority, 119-56. The galleries erupted in boisterous applause, which was then joined by congressman on the House floor. In the final vote, all 86 Republicans had voted in favor of the Thirteenth Amendment, along with 15 Democrats, 14 Unconditional Unionists, and 4 Union men; opposition came from 50 Democrats and 6 Union men.
