Gone Fishin'
The issues is three for an attack on Washington in 1861. One is the confederacy were badly disorganized as well. Two it rained the following day which made it hard to keep up a pursuit. Three the US had already started fortifying and being reinforced by 3 years troops. Stonewall Jackson Brigade was in no shape to advance and he himself was wounded. I also read that the confederate had supply issues as well.

I disagree that it’s game over,but it’s a game changer
In the long run it might be a disadvantage, because if Lincoln can avoid congressional backlash he can use this to finally have public support with him.
