From the brigade marker on the Antietam battlefield:

Christian’s Brigade advanced from the Poffenberger Woods in support of Hartsuff’s left. The 90th Pennsylvania was detached to support Matthew’s Pennsylvania Battery in the field between D. R. Miller’s and the East Woods, but soon thereafter rejoined the Brigade, which moved through the East Woods and came into line on either side of the Smoketown Road, the 26th and 94th New York forming on the west edge of the East Woods, south of the Smoketown Road. The 88th Pennsylvania fought on the line of, and finally relieved, the 83rd New York, which was the left of Hartsuff’s Brigade, the 90th Pennsylvania relieving the right of Hartsuff and charging about 40 yards beyond it. The Brigade fought until its ammunition was nearly exhausted when it was relieved by the advance of the Twelfth Corps. This tablet marks the point reached by the 90th Pennsylvania.
