Seven Days Battles

Battle of Malvern Hill

Captain Van A. Leonard of Company I was mortally wounded.

Second Battle of Manassas

The 20th Georgia lost 152 casualties. Lieutenant Robert Jordan of Company C was killed.

Battle of Sharpsburg, or Antietam

The regiment was commanded by Colonel Cumming. It lost 4 men killed, 47 wounded and 17 missing, about a quarter of its effective strength of 250 men, defending the bluff behind what would become known as Burnside’s Bridge.

From the first of two War Department markers for Toombs’ Brigade that were on the Antietam battlefield, located on the Harpers Ferry Road just south of Sharpsburg:

Toombs’ Brigade took position on the evening of September 15, on the bluff commanding the Burnside Bridge and ford a short distance below. His skirmishers and several Batteries of Artillery engaged the enemy during the afternoon of the 16th. On the morning of the 17th the Brigade was exposed to a heavy fire from the enemy’s Artillery on the opposite side of the Antietam. Between 9 A.M. and noon the enemy made several attempts to carry the bridge, but failed. An assault at 1 P.M. was successful and the Brigade fell back and formed line in this road, on the extreme right of the Division and co-operated with Archer’s Brigade of A.P. Hill’s Division in checking any further advance of the enemy.

From the second of two War Department markers for Toombs’ Brigade that were on the Antietam battlefield, at one time on the west side of Branch Avenue but no longer standing:

On the morning of the 17th, the 2d and 20th Georgia of Toombs’ Brigade, the 50th Georgia of Drayton’s Brigade, and a Company each of Hood’s Texas Brigade and Jenkins’ Brigade occupied a position commanding the Burnside Bridge and Snavely’s Ford. At 1 P.M., the Ninth Army Corps forced the passage of the bridge and ford, and Toombs withdrew his command to the Antietam Furnace Road in the suburbs of Sharpsburg. During the engagement at the bridge and ford, and while falling back, Toombs was joined by the 15th and 17th Georgia, of his Brigade, and five Companies of the 11th Georgia of Col. George T. Anderson’s Brigade. Re-forming his command on the Antietam Furnace Road, where he was joined by portions of Kemper’s, Drayton’s and Garnett’s Brigades, Toombs advanced on the left of Archer’s Briagade of A.P. Hill’s Division and, at this point, engaged the Federal troops in the lane and fields beyond. Late in the afternoon his command was relieved by Branch’s Brigade of A.P. Hill’s Division and moved easterly across the Sharpsburg Road, where it remained until withdrawn to re-cross the Potomac.

From Colonel Cumming’s Official Report on the 20th Georgia in the battle:

On the 15th instant I was stationed at a post as picket guard, which post was the scene of action on the 17th, so far as my regiment was concerned. On the evening of the 16th instant, the enemy appearing in force, I sent out a body of skirmishers, who were driven back. Early the next morning the enemy showed in great force – at least three brigades, supported by artillery, among which were some mountain howitzers. They poured a heavy fire upon us, which continued almost uninterruptedly for nearly five hours. My regiment, about 200 strong, maintained its position, inflicting a heavy loss to the enemy, killing and wounding, according to statements of some members of my command who were taken prisoners, nearly 1,000. The fire of the enemy continued in undiminished force, and as all the ammunition available on the ground from the boxes of the dead and wounded men had been expended, and being enfiladed by a battery which the enemy had planted on our left, I deemed it proper to withdraw my command. This order was not given until the advancing enemy were within six or seven yards of my line. A portion of the regiment under my immediate command returned to the engagement during the afternoon and fought on the right of the Fifteenth and Seventeenth Georgia Regiments until after dark. When men acted as my command did, I cannot mention the names of any who particularly distinguished themselves, as every one did his whole duty. Accompanying this is my list of casualties, showing: Killed, 4; wounded, 47; missing, 17; total, 68.

Battle of Fredericksburg

Battle of Gettysburg

The regiment was commanded by Colonel John Augustus Jones and brought 525 men to the field. It lost 25 men killed, 84 men wounded, and 28 missing in fighting along the Wheatfield Road.

From the War Department marker for Benning’s Brigade on the Gettysburg battlefield:

July 2. Arrived and formed line about 4 P. M. in rear of Law’s and Robertson’s Brigades and moving forward in support of these took prominent part in the severe conflict which resulted in the capture of Devil’s Den together with a number of prisoners and three guns of the 4th New York Battery.

July 3. Held Devil’s Den and the adjacent crest of rocky ridge until late in the evening when under orders the Brigade retired to position near here. Through mistake of orders the 15th Georgia did not retire directly but moved northward encountered a superior Union force and suffered considerable loss.

July 4. Occupied breastworks near here facing southward until midnight.

July 5. About 5 A. M. began the march to Hagerstown Md.
