Luke again took the Union, while I took the confederates. I had more luck with the placement of my fort and the forces I started with getting CSS Arkansas right up against two of the Union Ironclads from the start and a fierce firefight started immediately, me forcing the Union to move by releasing a fire raft into them.
Combined with the fire from my fort, I exploded one of Polk's turtles, and then rammed another with CSS Van Dorn, before she was crippled herself. The massed fore of a surprisingly resilient Arkansas and the Fort pushed the Union fleet to navigate a narrow strip of river on the opposite bank between the bank and a line of river pilings (we use these to represent sandbanks).
As my final ships turned up, there was no sign of the last Union ironclad and the final floating ship was the third of the Union Cairo class, and was already badly damaged and facing the might of the whole Confederate flotilla, so Luke conceded a major victory to the confederates.
