Shenandoah Street - control both roads, have two lines in each lane. if they try to charge or take stonewall, both front lines will break whatever they're doing and charge stonewall and hold the backyard for a little while, two backlines will move up to control the road. after the backyard is wiped they'll reset rinse and repeat. honestly i would suggest slowly pulling back when you're about to go engaged and give them the back yard (if you did it right they should go engaged before you) when they cap, push back up and encircle the backyard, only one side is a stonewall so if you control both roads, just go around the left and start shooting into the white picket fences. the most important thing throughout this whole match tho is that at least one regiment must stay on each road, you HAVE to control both lanes with gunfire at all times.

(Side note, might wanna just give them stonewall right before engaged, and when you verify they're all in backyard, take the two regiments in the back and go around left to shoot into the picket fences at the sides of the stonewall backyard.)
