sed, more and more people in the North would come to agree with these aims. While battles raged throughout the South, Douglass traveled on the lecture circuit, calling for Lincoln to grant slaves their freedom. On April 16, 1862, the president signed a bill outlawing slavery in Washington, D.C., but he was slow to approve congressional measures confiscating slaves in captured areas of the South.
