In April of 1961, Ft Sumter had fallen. In OTL, Lincoln, in response, calls up an army of 75,000 troops to 'put down the rebellion'. He actually sent messages to every remaining state in the union, informing them of their 'quota' of troops to enlist.
This enraged the four border states of Virginia, North Carolina, Tennessee and Arkansas, which quickly suceeded from the Union after weeks of trying to stay neutral. Missouri, Kentucky, Maryland, and Delaware did not succeed, but were so hostile that the Union had to all but occupy them to ensure relative cooperation.
What if...
Lincoln calls upon the several states to provide troops only on a voluntary basis to assist in 'preserving the Union' (The 75,000 troop target was easily met in OTL from the remaining loyal states). Furthermore, he waits a bit longer and gets the full backing of congress rather than ruling by executive order, so that the border states don't treat this as 'Mr Lincoln's War'.
Now the war is less 'North Vs South' (and therefore 'free' vs 'slave') and more 'Cotton States against the Union'. The slavery sentiments in those states that depended heavily on cotton was much more than in other 'slave' states, as the value of slavery elsewhere was much more marginal. Slavery would have probably vanished soon enough in some of these other states just due to pure economics.
(BTW, I find the practice of human slavery repugnant, and I do not wish anything discussed on this thread to be taken as an endorsement of slavery in any form. We are merely exploring alt-history during a period where the 'peculiar institution' is not yet eliminated)
