mies. McClellan remained supreme commander. Lincoln tried General                   Henry W. Halleck at the top military position. He was a failure. Halleck gave                   good advice but was a flake when it came to being decisive in military action.                   Initially, Lincoln stated that he would leave slavery alone where it existed.                   However, abolitionists were urging Lincoln to “teach rebels and traitors that                   the price they are to pay for the attempt to abolish this country must be the                   abolition of slavery.” On the other hand, there were also Northerners who                   supported the Union but not emancipation. Lincoln worried about the support                   of these states and the loyal slave states: Kentucky, Missouri, Maryland, and                   Delaware. Lincoln wanted to start emancipation in the loyal states and sweep                   the rebel states with it as they were conquered, giving money to slave owners                   as their slaves were freed. He suggested this plan to the loyal slave states’                   congressmen. However, they didn’t like it. “Emancipation in the cotton states                   is simply an absurdity,” said a Kentucky congressman. So, Lincoln changed                   his plan. He realized that slavery was crucial to the South’s success in the                   war. If he could get rid of slavery the south would be crippled and would lose                   any support from Britain. Britain was willing to help the south because they                   supplied cotton to them. Without slaves the South could not produce nearly                   as much cotton. There was too much antislavery sentiment in Britain for them                   to support a country’s fight for the preservation of slaves. Besides, the Union                   also needed troops and slav...
