The Confederates defend the pass

Union (Chris & Mitch): 8 brigades of 6 regiments + 4guns (all freshly minted 3-D printed 15mm)
CSA (Mark & SteveJ): 6 brigades of 6 regiments (all old minifigs).

The Rebs have improvised defenses thrown up across the pass flanked by think woods.  Most of their troops are out of sight, positon recorded by cards.

The Union have made a rapid advance.  
Rebs have appeared at the edge of the woods on both flanks sending skirmishers forward to harass the flanks of the Union advance.

On the far flank the Reb skirmishers have been driven back & therre is a stalemate. 
On the left of the ridge the first Federal wave has been beaten off.  The attack on the right side of the ridge has only just gone in.  More Rebs have appeared in the woods on the immediate right of the ridge.
On the near flank both sides have a brigade engaged.

The Union attack on the left side of the ridge has been broken off with heavy losses.
The attack on the right of the ridge has broken through the front CSA line.

The Union tried to support the breakthrough, but it has been halted by Reb reserves & flanked.  

View from the CSA side as the Union breakthough has come to a sticky end. 

The game was played with our M2M house rules & took about 1 3/4 hours.
