I would recommend the Columbia series of Civil War games. Easy to to play, 8 pages of rules, including examples of play & historical commentary. Try SHENANDOAH. A good, light game of a critical part of the war.
You're talking about Shenandoah: Jackson's Valley Campaign (of which you're a designer), right?
But it seems OP is looking for PNP (print-and-play) wargames.
