The Rebel attack came upon a staunch Union defence of the Peach orchard (bottom right below), and also simultaneously attacking Devil's Den (top right below, a rough patch near the top of the river) which was infested with Union sharpshooters:
The Rebels pressed hard and broke through in resounding success in the Peach Orchard. Driving two veteran Union regiments back in total disorder:
A third Union regiment was pushed back also in disorder after the breakthrough combat. A resounding Rebel attack that had broken/buckled the Union defences:

The best the now "worn" Union forces could do was to try and improvise another line of defence to face the inevitable Rebel onslaught (trouble was the Rebels were still classed as "fresh" and "up for it" whereas the Union were "worn" and "sick of it").

The next round(s) of combat here would be interesting.
