Bates's tenure as Attorney General generally met with mixed reviews. On the one hand, he was important in carrying out some of Lincoln's earlier war policies, including the arbitrary arrest of southern sympathizers and seditious northerners. On the other hand, as Lincoln's policies became more radical, Bates became increasingly irrelevant. Bates disagreed with Lincoln on emancipation and the recruitment of blacks into the Union Army. In 1864, Lincoln nominated Salmon P. Chase to be Chief Justice, an office Bates had wanted. Bates then resigned and was succeeded by James Speed, a Kentucky Lawyer with Radical Republican views.
