The regiment was organized at Camp Brown (located near Smyrna), Cobb County, Georgia, on April 22, 1861, under a special act of the Georgia legislature. (See also Philips' Legion Background and Formation). It was originally designated First Regiment, Fourth Brigade, State Troops under the following officers:
The volunteers trained at Camp Brown until transferring to Camp MacDonald at Big Shanty in present day Kennesaw; the new, 60-acre facility opened on June 11, 1861.[1] Phillips, founder of the famed Phillips Legion, named the camp in honor of his former law mentor and governor of Georgia Charles J. McDonald.
The regiment drilled for two more months after which the "Fourth Brigade" was broken up and sent north on August 2, 1861.[2] At that time, the 18th Georgia Volunteer Regiment was composed of ten companies of roughly 750 soldiers,[3] mostly from central counties in Georgia.
Two months later, the regiment distinguished itself again at the Second Battle of Bull Run (aka. Battle of Second Manassas) where members captured two stands of colors (those of the 24th and 10th New York Infantry regiments),[citation needed] and where, along with the Texas Brigade, they spearheaded General Longstreet's assault on Union General John Pope's left, nearly wiping out the 5th New York Zouaves and captured a battery of four guns. Regimental casualties were 37 dead and 87 wounded.
Three weeks later, September 1862, the 18th GA fought at the Battle of Antietam losing 14 killed and 30 wounded.[4]
Under orders of the Confederate States War Department, the 18th Georgia Infantry was transferred from the Texas Brigade to Cobb's Georgia Brigade, McLaws' Division, remaining in Longstreet's Corps. Cobb's Brigade was now composed of the 16th, 24th, and 18th Georgia Regiments, Cobb's Legion, and Phillips' Legion. (The 18th GA remained assigned to Longstreet's Corps until the end of the war.) Now consisting of 160 barefoot men the 18th GA went into camp at Fredericksburg, Virginia. In the ensuing Battle of Fredericksburg, the regiment fought behind the stone wall on Marye's Heights sustaining losses of 14 killed and 30 wounded while inflicting heavy casualties upon the enemy.[citation needed] General Cobb bled to death from wounds sustained during the battle. May 1, Col. Wofford assumed command of the Texas Brigade.
Jackson's Corps, with McLaws' Division on the left flank, remained on the Fredericksburg front until the night of May 1. On that night, Jackson's force (containing the 18th GA) left Fredericksburg to outflank the outflanking Federal army. Thus began the Battle of Chancellorsville. After days of fighting, the 18th GA's casualties totaled 86; 14 killed and 72 wounded.
In June, 1863, Gen. Lee launched his second invasion of the north. Around Gettysburg, on the second day of battle after taking the city, Lee ordered Longstreet's Corps to attack diagonally from Little Round Top northward. The Confederate attack, coming late in the afternoon, saw Longstreet capture the positions west of Little Round Top known as Peach Orchard, Wheat Field, and Devil's Den on the Federal left. But, he failed to seize the vital Little Round Top.
After Gettysburg, the 18th GA retreated to an area near Manassas Gap, in Virginia. They fought a skirmish at Snickers Gap, Virginia on July 23, 1863, and did not see action again until October.
In September 1863, Longstreet's Corps left the Army of Northern Virginia by rail to join the Battle of Chickamauga in northwest Georgia, near Dalton. The corps bolstered the forces of General Braxton Bragg's Army of Tennessee. But, the 18th Georgia did not participate since they arrived on the field the day after the battle. October 28 and 29, 1863 found the 18th Georgia engaged in battles around Wauhatchie, Tennessee.
Bragg sent Longstreet's Corps off, with the 18th GA, in a futile attempt to capture Knoxville on November 5. The 18th Georgia Regiment found itself in a small skirmish on November 15 at Little River, Tennessee. On the 29th, Longstreet attacked Fort Sanders, but his troops were slaughtered in the ditches around the fort. He withdrew, and on December 3 started northward. By December 12, 1863, his forces arrived at Rogersville, and on the 15th he attempted to capture three brigades of Federal cavalry at the Battle of Bean's Station. The attempt failed although it was a Confederate victory.
January 16 and 17, 1864, the 18th Georgia was engaged in operations around Dandridge, Tennessee, east of Knoxville. April 11, Longstreet received orders to return to the Army of Northern Virginia.
By May 5, Longstreet was back in the lines with General Lee. On May 5, 1864, Gen. Longstreet's Corps was hit by the Federals on Old Turnpike and Orange Plank Road in the Battle of the Wilderness. By May 7, the Union had lost and General Grant was looking to maneuver around Lee's forces.
But, on May 8, Grant met heavy resistance at the famous Battle of Spotsylvania Courthouse. By May 12, savage hand-to-hand fighting at Bloody Angle with Longstreet's men in the left flank. May 19, the battle finally ended with Grant being thrown back. The same forces met again, at North Anna River, May 22 – May 26, the Pamunky River, May 26–28, and at the Totopotomy Creek, May 28–31.
Then, at the Battle of Cold Harbor (May 31 - June 12), northeast of Richmond, Grant launched several very heavy attacks against Lee's army, including the 18th Georgia Regiment.
The 18th Georgia Regiment is listed as being engaged in the Assault on Petersburg, June 18, 1864. The siege of Petersburg lasted from June 16, 1864 until April 1865.
August 7, 1864, the unit was reassigned to operations against Sheridan's Campaign in the Shenandoah Valley where the 18th Georgia saw many small battles. August 16, they were engaged at Cedarville, and Guard Hill (Front Royal), Virginia. They next saw action at Bunker Hill, West Virginia September 2 and 3rd. On September 19, they saw action in the Battle of Opequan in Winchester, Virginia. Three days later, on the 22nd, the regiment saw action at the Battle of Fisher's Hill near Strasburg, Virginia. And lastly, on October 19, 1864, the unit saw action in the Battle of Cedar Creek, Middletown, and Belle Grove, Virginia.
November 30, 1864, the 18th GA was reassigned to the Army of Northern Virginia and moved back to Richmond. The siege on Petersburg and Richmond continued until Lee was forced to evacuate both cities April 2 and 3, 1865. An 88 mile (142 km) chase ensued down the Appomattox River to the southwest. Confederate forces were detained at Amelia Courthouse April 4 and 5, waiting for supplies that never arrived. The Confederates, including the 18th Georgia, were badly cut up on April 6 at the Battle of Sailor's Creek.
Finally, on April 8, 1865 the 18th Georgia Regiment, assigned to Gen. Kershaw's Division, Gen. Longstreet's First Corps, Army of Northern Virginia was represented at the surrender of Confederate Forces at Appomattox Court House by less than 60 members, the highest ranking of which was one Lieutenant Gideon J. Lasseter.
18th GA was under the command of Col William T. Wofford and LtCol Solon Z. Ruff. The 18th lost 146 killed or wounded at Gaines's Mill where they were used as "shock troops".
Boonsboro Gap was called the Battle of South Mountain by the Union. At Sharpsburg (Antietam), LtCol Solon Z. Ruff in command of the 18th went into battle with 176 men, losing 101 of those (57%) killed, wounded, or missing.
LtCol William H. Luse in command of the 18th, going into Fredericksburg, consisted of 160 barefoot men, transferred to Cobb's Brigade, McLaws' Division, remaining in Longstreet's Corps.
During the campaign, the 18th was under the command of Capt J. F. Espy and Lt Gideon J. Lasseter. Capt Espy moved to take command of Brig Gen DuBose's Brigade when DuBose was captured at Sailor's Creek, and Lasseter stepped in to command the 18th. Their division commander, Maj. Gen. Joseph B. Kershaw, was also captured at Sailor's Creek.
