Rickett’s Division, First Army Corps

Brig. Gen. James B. Ricketts, Commanding.

September 17, 1862

Ricketts’ Division, on the left of the First Corps, formed for attack at 6 A. M. in the follwing order: Hartsuff’s Brigade in advance, supported by Christian’s Brigade on the left and Duryea’s Brigade on the right. The Division advanced to the west edge of the East Woods and along the south edge of the Cornfield, where it became heavily engaged with the enemy.

It maintained itself in this position for some time but, it’s ammunition having been exhausted, it was eventually obliged to withdraw. After replenishing its supply of ammunition, it was formed, in reserve, in the fields east of the Hagerstown Pike and remained there throughout the day.

No. 7.
