Across A Deadly Field: Regimental Rules for Civil War Battles [PDF ebook] 

The American Civil War was a turning point in the history of warfare, as Napoleonic tactics met deadly new technology. Cannons and rifles had become more accurate at longer ranges, rapid-fire pistols gave cavalry a new weapon, and the telegraph and railroad completely altered both strategic and tactical thinking. Across a Deadly Field, the new regimental-level wargame from Osprey Publishing, allows players to recreate this tumultuous period of warfare on the tabletop. Its versatile rules make it possible to refight any battle, from the early skirmishes of Ball’s Bluff and Big Bethel to the grand, set-piece battles such as Gettysburg that decided the war. Written by John Hill, designer of the Johnny Reb series, Across a Deadly Field offers both new and experienced wargamers a fast-paced and dynamic game where even a single regiment can make the difference between victory and defeat.
