I'm working on a TL that I will post within some months.
The TL is already planned until the 1890's. The POD is a Conservative victory in the Reform War.
But I need help on some points.
First, the ACW.
In this TL, I planned the death of E.K. Smith at the first battle of Bull Run.
Thus, Beauregard is sent in East Tennessee in earlier 1862.
Consequently, Columbus is besieged by Pope instead of Island Number Ten.
A.S. Johnston is more successfull at Shiloh. The siege of Corinth is delayed and Pope is killed or remains in Tennessee, but is not sent in Virginia.
In Virginia, the Peninsular Campaign goes as in OTL, but the Northern Virginia Campaign is less disastrous than in OTL for the Union as Burnside is named to command the Army of Virginia.
In september, the Maryland Campaign occures as in OTL, and still ends into a Union victory. Thereafter, Hooker become the commander of the Army of the Potomac, and he uses the winter to reorganize.
In earlier spring 1863, Hooker launches a new offensive into Virginia, using the strategy chosen in OTL by Burnside with more success in the beginning as he manages to cross the Rappahannock River before the arrival of Lee.
But the battle of North Anna is a disaster for Hooker (the ATL equivalent of Chancellorsville).
Lee launches in late spring his offensive into Pennsylvania. Stonewall Jackson is still alive, and Lee is more successfull than in OTL. Harrisburg is briefly occupied by Stuart. Jackson manages to win the battle of Gettysburg in extremis in just a day. Thereafter, Lee encounter Meade at the Pipe Creek Line. Meade manages to hold off the confederate assaults and Lee retreated into Virginia.
This is a summary of what I planned for the ACW. But I'm not sure about the events in the western theatre after the siege of Corinth in summer 1862, and in Virginia after the Pennsylvania campaign of spring-summer 1863.
My goal is to have McClellan elected president in 1864 and to have an armistice signed in summer or autumn 1865.
Suggestions?
