In the Trenches: Through Mud and Blood is the third game of the In the Trenches series. Designed by John Gorkowski, this series enables players to game historically accurate simulations of tactical operations from the Great War. ITT challenges players to move and fight with company-level formations made of separate platoon-sized units during five minute, impulsed-based turns. The historically accurate maps are scaled to 100 yards per hex. This approach recreates WWI command and control problems and inspire historically accurate play without forcing decisions.

In the Trenches: Through Mud and Blood includes seven operations. "Balkan Brawl" takes place in Macedonia, "Schneiders at Juvincourt" pits French tanks against German infantry, "The Lost Battalion" and "Go to Hell!" depict the battles of the 308th US Infantry Battalion in the Charlevaux Valley, "War of Machines" and "Combined Arms" involves British and German tanks on the Western Front, and "Kaiserschlacht" depicts trench fighting between the British and Germans during the last German offensive of the First World War.

Included in In the Trenches: Through Mud and Blood are five 11.5" x 8" maps, 264 die-cut counters, one rulebook, guides for all seven operations, one reference card, and two D6s.

In the Trenches: Through Mud and Blood is a stand-alone game. Ownership of the other two games in the series is not required to play this game.
