2. The territorial integrity of Virginia (and Tennessee) is not up for negotiation. Period. There can be no West Virginia in any CSA victorious scenario.
The US is not going to hand over any state they control to the CSA. The Confederacy getting West Virginia is extremely unlikely. In a peace by exhaustion, which I feel is the most likely CSA win, the Confederacy will lose most or all of Tennessee and Arkansas at best.
No matter how good they do, the CSA is only going to get territories that they can take and hold. In OTL, they abjectly failed to take and hold Maryland, West Virginia, Kentucky, Missouri, and Arizona. A timeline where they get any of those is a CSA-wank.
Arizona and Indian Territory are unquestionably going to the CSA, as per the map. One should note there is no need to "conquer" AZ, it seceded on its' own and in the typical war ends in 1862 scenario is still an established CS territory.
Perhaps in the timeline you come from.
In OTL, the CSA got their butts kicked in the New Mexico Campaign by a mix of US regulars, Colorado and New Mexico volunteers, and New Mexico territorial militia. The Confederates only had about 2500 men, had difficulty supplying them, lost over a third of their force, and by July 1862 lost all of Arizona Territory, plus a bit of west Texas.
The question is would the CSA gain the six pro-Confederate counties of California?
You mean the
two nominally pro-Confederate counties of California. To call their support for the Confederacy tepid is understating things. A couple dozen Californians took up arms for the Confederates.
The only way the Union loses southern California is if the British intervene militarily. It will only stay "Confederate" as long as Britain continues to commit military force.
This would give them access to the Pacific and they'd drive the Southern Pacific Railroad through to Los Angeles, probably before any Union effort was completed.





Please tell me you're joking. Don't you know anything about period rail construction capabilities?
