Battle of AntietamThe Third Maryland Infantry Regiment was commanded by Lieutenant Colonel Joseph M. Sudsburg. It brought 148 men to the field, losing one man killed, 25 wounded, and four missing in the fighting that brought it to the corner of the Dunker Church. From the first War Department marker for Stainrook’s Brigade on the Antietam battlefield, along Smoketown Road: Stainrook’s Brigade, on the left of the Division, advancing in line south of the Smoketown Road, relieved the left of Crawford’s Brigade and engaged the Confederate Infantry in the East Woods. Upon their retreat, the Brigade followed through the East Woods, across the open ground south of Mumma’s house to the ridge southeast of the Dunkard Church, where it was halted to replenish ammunition. From the second War Department marker for Stainrook’s Brigade on the Antietam battlefield, near the Dunker Church: After the Confederate right flank had been turned, Stainrook’s Brigade pursued through the East Woods, crossed the fields to the left of the burned out buildings of the Mumma farm, and halted behind the ridge a few yards east of this point where with the assistance of Monroe’s and Tompkins’ Rhode Island Batteries, it protected the right of French’s Division of the Second Corps, and repulsed several assaults of the enemy. About 10:30 A. M. the Brigade crossed this road and entered the woods on the left of the Dunkard Church, its left on the road directly opposite this tablet where it remained until noon when it was compelled to retire to the East Woods. From Lieutenant Colonel Sudsburg’s Official Report for the 3rd Maryland Infantry at Antietam: We rested from 3 o’clock a. m. in a field about 1 mile from the bridge over the Antietam. At 6.30 o’clock in the morning General Greene, commanding the division, marched us from this field in column by companies, and, advancing in a southerly direction, we reached a point about 1 mile from our starting place. We here met the enemy, who was in possession of a piece of woods. Deploying in line of battle, we here met our first loss; 3 of our men fell. After a short but severe contest, we drove the enemy out of this wood and across a newly plowed field. This woods was filled with the wounded and dead of the enemy, who had taken refuge behind one of the batteries in front and toward our left. Arriving at the farther end of this field, we halted for some minutes, in order to form again in line. Our left rested on a burning farm-house, said to have been the commissary store-house of the enemy, who had, before leaving, set fire to the same and thrown his salt in the well. After again being formed, we advanced over a meadow toward the battery of the enemy, who had vigorously shelled us during our advance from the woods. Arriving behind the crest of a little elevation, we were ordered to lie down and await the arrival of a battery which had been ordered to our support, and of which a section shortly came up and unlimbered. A full battery, said to have been Knap’s, came up soon after and went directly into action. The enemy’s infantry advanced from the right, apparently designing to take our battery. We were ordered up, fixed bayonets, and charged forward past the battery, which in the mean time had given the enemy the benefit of two rounds of canister. We drove the enemy, who flew before us across the fields and across the road leading from Bakersville to Sharpsburg. On the other side of the road is a church or school-house, surrounded by woods. Charging through this piece of woods, we drove the enemy out, and held possession nearly two hours. The enemy occupied a corn-field in front of us, and, judging from his fire, must have been in strong force. In this woods I lost most of my men. I took 148 men into action. Our casualties amount to 1 killed and 25 wounded, some of whom have since died. Four were missing. |
