While the cavalry is stunned into doing nothing, a small unit of rebels crashes into the artillery, handily routing it. This leads to a breakthrough assault on the flank of the large union unit. Flush with success and hooting their crazed rebel yell, the union is dispatched with such ferocity the entire unit disappears as a viable entity.
This flank is largely a mop up operation for the confederates now, and the cavalry rushes back towards Gettysburg to support the advance.
On the left, which was expected to be an easy go for the confederates, everything is as expected. There's a massive, but slow, breakthrough in the woods.
The union speedbumps on the road are recoiling fast and losing men.
The rebel left and centre have just about connected, to pressure Gettysberg from multiple directions.
At the town itself, the union reinforcements have fully engaged with the rebel push in the centre. Desperate to change the tempo of the battle, the men in the cornfield advance agressively to try and put a rebel unit out of the battle.
Unfortunately, the cavalry from the right flank chooses this time to reappear and charge into battle.
History does not repeat itself and the union manages to chase off both the cavalry and the rapidly diminishing rebel brigade facing them.
Despite local successes, the day is lost for the union, as the confederates have handily taken Gettysberg and are still have day light to march on the important hill to the North.
