Command Combat: Civil War - 1864 is now available on Wargame Vault, Amazon, and through the Command Combat website. The links are provided below.
The 1864 expansion provides the generals and units most notable during that year of the war. The Confederates were getting desperate for troops and the Union was growing stronger with more powerful units. However, the veterans are beginning to tire of war and are less likely to go on foolhardy charges.
The expansion also comes with rules for playing campaigns, and includes the historic campaigns Red River, Atlanta, and Overland.
