General Grant commented in The Papers of Ulysses S Grant, Vol. 11, p. 362, "(it is) the saddest affair I have witnessed in this war." This is a tower defense game simulating the "Battle of the Crater" in the American Civil War. You are Brigadier General Mahone of the Confederate States of American (CSA). Can you try for a better historical outcome!
In this seven-hour battle the Union last 4,000 troops. It is the first battle the USCT ("United State Colored Troops") savagely fought against their former slave-owners.
This is one of several tower defense games from the "Building Tower Defense Games" workshop. The Construct3 and Construct2 source code with instructions are only available in this workshop's book.
