he thought he could free slaves in the rebel states becuz he thought that if he frees slaves than there will be more men in his troops he could use those free slaves to increase the men.and he didn't free slaves in the union part becuz people are already getting mad at him. the reason for this is that all the free slaves are going to take the white peoples jobs in the union.and Abraham didn't want the unions to be more mad at him and eventually go against him
