This scenario is included within the rules book –
Day 1 at Seven Pines, with the Union Army at the gates of Richmond, VA, Gen. Joe Johnston sends his Rebel Divisions to attack Gen. McClellan’s Divisions south of the flooded Chickahominy River. With the Southern men on the march early it is the opportunity that Gen. Johnston has waited for, to bring mass against a smaller portion of the Union Army.
The battle develops into two separate actions divided by the east/west railroad line with the northern field often called the Battle of Fair Oaks. CSA Gen. Smith attacked to break through the flank of the Seven Pines lines only to run into the Union Division of Gen. Sedgwick’s men rushing to battle.
South of the Railroad line, the Rebel Division under Gen. Daniel Harvey Hill attacked the light works of Casey’s U.S.A. Division line at Seven Pines.
The Scenario has the Rebels hitting hard all along the front, but with Union reinforcements, a stiffening line stops the breakthrough.
