Two game set covering pivotal World War One battles of Tannenberg and The Marne.
Low-complexity for a wargame. Player's units are grouped into armies which have variable movement rates (based on a die roll) each turn. Units are rated for strength and efficiency. Special rules for artillery, supply, victory point hexes, fortified zones, forts, and strategic movement.
Rated very high for solitaire play.
Nominee for the 2001 Charles S. Roberts awards for Best Pre-World War II Boardgame (Charles S. Roberts Awards).
