War of Seccession, 1862-1880
By September, 1862, the American Civil war was in a deadlock. Union attempts to take Richmond had been repulsed, and Confederate attempts to push the Union out of Tennessee and Virginia have failed. Nevertheless, Robert E. Lee decides that a victory on Northern Soil would be a decisive victory. Southern chances of victory were dwindling, as was their man power.
The Union could replace its losses, the Confederates could not. If there was a time for victory, it was now. The Confederate invasion of Maryland began and Lee devised plan 191, which he gave to General Stonewall Jackson. The Confederates catch the Union army of the Potomac completely by surprise, and they destroy it at the battle of Antietam.
Most of the army was crushed and the rest surrendered, leaving a scant few survivors to defend union cities. Philadelphia and Vermont are captured, and the Confederates siege Washington. The Union is forced to divert troops from Tennessee to fight the confederates.
This allows a series of offensives by the Confederates to push the Union out of Tennessee and overrun Missouri and Kentucky, and then march to the Great Lakes by December.
In Europe this news is met with a recognition of the Confederacy from Britain and France, and the two nations force mediation between the two nations, The Treaty of Edinburgh ends the War, and it is forever known as the War of Southern Secession.
Lincoln resigns the presidency and the new president recognizes the South and pulls Union troops out of the south. Missouri and Kentucky are ceded to the Confederacy, as our indian territory in what is now Oklahoma as well as Southern Arizona and New Mexico.
Following the war's end, the government is in heavy debt and a depression begins in 1866 and runs to 1870.
