paragraph_text: Emancipation Proclamation
  
  The Federal government's power to end slavery was limited by the Constitution, which before 1865, was understood to reserve the issue to the individual states. Lincoln believed that slavery would be rendered obsolete if its expansion into new territories were prevented, because these territories would be admitted to the Union as free states, and free states would come to outnumber slave states. He sought to persuade the states to agree to compensation for emancipating their slaves. Lincoln rejected Major General John C. Frémont 's August 1861 emancipation attempt, as well as one by Major General David Hunter in May 1862, on the grounds that it was not within their power and might upset loyal border states enough for them to secede.
  
  In June 1862, Congress passed an act banning slavery on all federal territory, which Lincoln signed. In July, the Confiscation Act of 1862 was enacted, providing court procedures to free the slaves of those convicted of aiding the rebellion; Lincoln approved the bill despite his belief that it was unconstitutional. He felt such action could be taken only within the war powers of the commander-in-chief, which he planned to exercise. On July 22, 1862, Lincoln reviewed a draft of the Emancipation Proclamation with his cabinet.
  
  Peace Democrats (Copperheads) argued that emancipation was a stumbling block to peace and reunification, but Republican editor Horace Greeley of the New-York Tribune, in his public letter, "The Prayer of Twenty Millions", implored Lincoln to embrace emancipation. In a public letter of August 22, 1862, Lincoln replied to Greeley, writing that while he personally wished all men could be free, his first obligation as president was to preserve the Union:
  
  My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union... I have here stated my purpose according to my view of official duty; and I intend no modification of my oft-expressed personal wish that all men everywhere could be free.
  
  When Lincoln published his reply to Greeley, he had already decided to issue the preliminary Emancipation Proclamation and therefore had already chosen the third option he mentioned in his letter to Greeley: to free some of the slaves, namely those in the states in rebellion. Some scholars, therefore, believe that his reply to Greeley was disingenuous and was intended to reassure white people who would have opposed a war for emancipation that emancipation was merely a means to preserve the Union. On September 22, 1862, Lincoln issued the preliminary Emancipation Proclamation, which announced that, in states still in rebellion on January 1, 1863, the slaves would be freed. He spent the next 100 days, between September 22 and January 1, preparing the army and the nation for emancipation, while Democrats rallied their voters by warning of the threat that freed slaves posed to northern whites. At the same time, during those 100 days, Lincoln made efforts to end the war with slavery intact, suggesting that he still took seriously the first option he mentioned in his letter to Greeley: saving the Union without freeing any slave. But, on January 1, 1863, keeping his word, Lincoln issued the Emancipation Proclamation, freeing the slaves in 10 states not then under Union control, with exemptions specified for areas under such control. Lincoln's comment on signing the Proclamation was: "I never, in my life, felt more certain that I was doing right, than I do in signing this paper."
  
  With the abolition of slavery in the rebel states now a military objective, Union armies advancing south "enable thousands of slaves to escape to freedom". The Emancipation Proclamation having stated that freedmen would be "received into the armed service of the United States," enlisting these freedmen became official policy. By the spring of 1863, Lincoln was ready to recruit black troops in more than token numbers. In a letter to Tennessee military governor Andrew Johnson encouraging him to lead the way in raising black troops, Lincoln wrote, "The bare sight of fifty thousand armed, and drilled black soldiers on the banks of the Mississippi would end the rebellion at once". By the end of 1863, at Lincoln's direction, General Lorenzo Thomas "had enrolled twenty regiments of African Americans" from the Mississippi Valley.
