Confederate States

[Bunnybrit]

There is no dobut the CSA could have won the war at a number of points, but they would have done with a decivise victory where the "Army of the Potomac" was  totally destroyed, and a tactical victory that Lee gained at "2nd Bull Run", or Chancellorsville, or a defensive victory such as Fredricksburg.
The places where Lee could have destroyed the Union forces are quite various:
1) During the 7 days campaign as already described .
2) A complete win at "2nd Bull Run".
3) The "Lost Order " isnt lost.
4) Jackson isnt killed at Chancellorsville, and Stonewall reaches the US Mine Ford(a road to which he was looking for when he was shot by his own men).
5) Gettysburg.
As for what the CSA would have looked like I think it would had for certain the following states:
1) Alabama
2) Arkansas
3) Florida
4) Georgia
5) Louisinia
6) Mississippi
7) North Carolina
South Carolina
9) Tennessee
10) Texas
11) Virginia
States I think would have joined the CSA.
1) Kentucky.
States that could have been divided between USA & CSA.
2) Missouri & Maryland.
Southern Missouri was very pro-CSA. As was parts of Maryland.
Territory that would have gone to the CSA.
1) The Indian Territory.(The current state of Oklahoma)
Territory that CSA might have got.
1) New Mexico Territory. (The current two states of New Mexico and Arizona).
Also Cuba I think would have gone to the CSA, and also to help bail out Emperor Max in Mexico the CSA might have gotten Territory there namely the states of Chinuahua and Sonora.

I agree that a decisve victory in which the main Union army is destroyed would have ended the war in the CSA favour. A win in Maryland or Penn in 1862 would have seen the French and British force a peace settlement.
A victory at Gettysburg was possable but not on the 3rd day with Picketts charge, that was always going to fail.
The best hope for Lee to win was on the 2nd day, by taking Little Round Top and outflanking the whole Union line, and dont forget that it was race for the Union to get troops on to that hill, and the race was won only by 10 minutes. If Warren had not spotted the weakness just say 5 minutes the battle could have well be a lot different.

Stonewall Jackson would had taken Culips Hill, he wouldnbt had stopped like Ewell, but again Gettysburg would have been a CSA win but NOT a decisive win in which the "Army of the Potomac" is destroyed.
What-if Hooker was still in control after all he was only sacked two days before the battle.

I agree Hancock did a lot to win the battle, also here is another what-if , What-if John Reynolds was not killed on the 1st day- would he if he been alive on the 3rd day forced Meade into a counter-attack that could well have destroyed Lee. Hancock pushed for it- but Meade said no- but with Reynolds pushing for it as well he might have changed his mind.
I do think the CSA could have won the war of that there is no dobut, it is just where and when?
