So your saying Lincoln freed the northern slaves? and Grant did not own a slave!!
Lincoln was instrumental in getting the 13th Amendment through the House and Senate, and made sure it was part of the 1864 Republican platform. That led to the end of slavery in the Northern states and your claim was that Lincoln did nothing to end slavery in the North. Grant owned one slave which he freed in 1859, not after the Civil Was as you also claimed. So both of those were incorrect.
