Mr. Lincoln's War: Army of the Potomac (1983)

From the contents:

Mr. Lincoln's War is an historical game which captures the epic struggle of the American Civil War. Mr. Lincoln's War is organized into two games, the Army of the Tennessee, which deals with the western theater, and The Army of the Potomac, which deals with the war in Virginia. Each game has four short campaign scenarios that recreate the maneuvers and battles of Shiloh, Gettysburg, Atlanta and other monumental Civil War contests. A grand campaign scenario enabling the players to fight the war in the West or East is provided with each game. Both games may be combined for a grand campaign game that simulates the entire Civil War on both fronts.

Each game contains the following components:
1) One 22' x 28' mapboard covering the eastern or western portion of the United States.
2) 400 die-cut playing pieces.
3) A rules booklet.
4) A scenario booklet.
5) One player-aid and leader display card.

Each hex represents about 12 miles.
Each strength point represents approximately 2,500 men.
Turns are monthly, except for the winter turns (November to February), which are bi-monthly.
