A nearly complete game published in RBM Studio's C3i Magazine No. 16 (2005). The issue contains die-cut counters, map, charts and special rules for the battle. Players must have the basic rules from Gringo! (or download them from the GMT Web site) to play. The game is a minigame based on the Great Battles of the American Civil War game system. The map is 11x17 inches, 15x18 hexes, showing the battlefield at Churubusco, Aug. 20, 1847. There are 136 counters, 75 of which are units and leaders. The rest are markers of various kinds. The Battle of Churubusco took place on August 20, 1847, while Santa Anna's army was in retreat from the Battle of Contreras or Battle of Padierna during the Mexican–American War. It was the battle where the San Patricio Battalion, made up largely of American deserters, made their last stand against U.S. forces. The U.S. Army was victorious, outnumbering more than two-to-one the defending Mexican troops. After the battle, the U.S. Army was only 5 miles (8 km) away from Mexico City.
