Clear for action! During the American Civil War the Union and Confederate navies clashed along the length of the Mississippi River fighting for control of the primary strategic waterway in North America. Often overlooked in this campaign is the Union invasion of the Red River valley in the spring of 1864. Support General Banks Union army, a massive United States naval armada steamed up the Red River with the goal of capturing Shreveport. What followed was a series of events that almost resulted in the loss of more Union warships than had been lost to date during the entire war. The game pits a large well equipped Union naval force against a smaller Confederate force of shore guns and torpedoes, backed by a single Confederate ironclad and the ragtag remains of the Confederate Mississippi gunboat squadron. While the battle rages, Union commanders jockey to amass a financial fortune by confiscating Confederate cotton bales to be turned in and collected as prize money. Anaconda: River of Blood is a supplement to the original Anaconda rules designed to generate tabletop miniature games simulating riverine naval battles during the Red River campaign. This supplement includes an order of battle for both sides, a strategic map of the Red River that replaces the original strategic map of the Red River, tactical maps defining sections of the Red River and special rules modifications to the core Anaconda game designed to replicate the events of the original campaign.
