In the early morning hours of Saturday, July 30, 1864, at about 4:40 A.M. EST, Confederate defenders of the earthworks near the city of Petersburg, Virginia at the Blandford Church were mostly still asleep; with the exception of some pickets observing the Union lines opposite their position. Both opposing lines were only about 130 yards apart.

These men included two regiments of South Carolina volunteer infantry and elements of a third regiment from the brigade commanded by Confederate Brigadier General Stephen Elliott Jr. and a four gun battery of Virginia artillerymen assigned to an earthwork fortification known as Elliott's Salient.

Less than five minutes later, over 300 of these men would be instantly killed and many others severely wounded.

Unknown to these Southern men, for the last several weeks, Union army engineers -- mainly Pennsylvania coal miners -- had been busy digging a T-shaped mine shaft that ran 512 feet from the Union lines directly beneath their position. Two days before, these same Union engineers placed 320 kegs of black gunpowder -- approximately 8,000 pounds (4 tons) -- in two passages no more than about 20 feet below Elliott's Salient, setting the stage for what would be one of the better known events during the entire 292-day Siege of Petersburg (Thursday, June 9, 1864 -- Saturday, March 25, 1865).

Several good books have been written about the events leading up to the Battle of the Crater telling in detail about the construction of, and the detonation of the mine and creation of the Petersburg crater; and about the subsequent Union military blunders and Confederate defensive actions that took place following the breach in the Southern lines. 

Yet often overlooked is the story of the South Carolina men from Elliott's Brigade who were standing post at the fortifications directly over the site where the mine was exploded early that fateful morning. Many of these men died while they still slept, and others killed instantly when the ground beneath their feet erupted into one of the largest non-nuclear, human-made blasts of the war.

When the dust settled, on the spot where Elliott's Salient had stood mere moments before, a massive crater approximately 170 feet long, 120 feet wide, and 30 feet deep scarred the landscape. A total of 353 South Carolina Confederates and Virginia artillerymen were instantly killed by the blast. Two of those regiments -- the 18th and 22nd South Carolina Volunteer Infantry Regiments -- would lose more soldiers killed and wounded in that one single blast and the subsequent than at any other point in the entire war.

Many of these men and boys were from companies in three particular regiments recruited from this writer's corner of South Carolina, from counties located in the Piedmont and Upstate regions. 

The following are the company breakdowns of each of the three regiments involved in the Petersburg mine explosion.

The mine explosion in the early morning hour of Saturday, July 30, 1864, instantly killed over 300 of these men, with others dying from wounds later in the field hospital at the nearby Blandford Church. After the explosion, the dirt-covered, shaken survivors were subjected to a heavy artillery barrage that resulted in even more casualties.

General Elliott himself survived the initial explosion, having been asleep in a bunker near the line and shaken awake by the blast. He would be seriously wounded in the chest and left arm while leading his remaining regiments of his shattered brigade in the counterattack against the Union assault. Colonel Fitz W. McMaster of the 17th South Carolina Infantry Regiment took temporary command of Elliott's brigade after the general was wounded, with his second in command, Major John R. Culp, taking temporary command of the regiment.

General Elliott would later be replaced as the brigade commander by Colonel William H. Wallace of the 18th South Carolina Infantry Regiment after the battle. Wallace's second in command, Lieutenant Colonel William B. Allison, would take over command of the regiment. Elliott would later return to duty and survive the war, surrendering with Johnston's Confederate Army of Tennessee in North Carolina in late April, 1865; but would ultimately die of his wounds -- which never fully healed -- less than a year later in February of 1866 in Aiken, South Carolina.

The 18th and 22nd South Carolina Regiments both lost about 278 soldiers in the initial blast and from mortal wounds as a result of the explosion (the 18th lost 82 and the 22nd lost 170 in the blast itself), while the 17th South Carolina Regiment lost 135 men from the explosion and later from fatal wounds in hospital from the battle that followed.

Twenty-two Virginia artillerymen from Pegram's Battery assigned to their cannons were lost in the explosion within hundreds of yards from the homes where they were born and raised. 

The heaviest casualties from the mine explosion and subsequent military action came from the 22nd South Carolina Infantry Regiment, which lost 216 men killed and wounded -- 170 officers and men were lost instantly in the mine explosion, including Colonel David G. Fleming, whose body was never recovered. William G. Burt was promoted to colonel and command of the regiment.

The 18th South Carolina Infantry Regiment lost seven of its officers in the explosion, including two Captains: John McCormick of Company A and W.P. Bridges of Company K; and five Lieutenants: Samuel H. Wolfe of Company A, W.M. Lawsom of Company C, John G. Bryant of Company D, John Anderson of Company E and John Foster of Company F.

To give y'all an idea of how badly these South Carolina regiments were decimated, at the end of the day only one man answered roll call from Company A, 18th S.C. Infantry, and only two from Company B, and three from Company C of the 22nd S.C. Infantry.

The Roll Call for the 22nd South Carolina Infantry Regiment two days before on July 28th numbered 329 officers and men. On August 1st, two days after the battle, the same roll call numbered only 86 officers and men.

It was the most tragic and devastating day for a single brigade of South Carolina soldiers. These units experienced immediate and devastating losses -- most of them men and boys from Spartanburg County who would lose more men in this one single day of the war.

The Battle of the Crater would ultimately go on to be a military disaster for the attacking Union forces due to several significant blunders and the strong defense by the Confederate forces. The end result would be the deaths and wounding of over 5,000 American soldiers (3,800 Union and 1,500 Confederate casualties) in an inconclusive battle that failed to accomplish anything significant for either side and cost so many more lives.

The Siege of Petersburg would stubbornly continue into the fall and winter of 1864-1865 with many more Americans on both sides dying from the horrible conditions of the trench warfare.

The remains of the crater from the mine explosion can still be seen today at Petersburg, Virginia. The Blandford Church located near the site of the crater and the Confederate lines served as a field hospital following the battle and serves as a memorial for those Confederate soldiers who died defending the city during the long siege.

The Adam Washington Ballenger Camp #68 of the South Carolina Division Sons Of Confederate Veterans erected a large flag pole on private property along I-85 in Spartanburg County in 2022 for the purpose of remembering those men of the 18th and 22nd South Carolina Infantry Regiments who were killed in the mine explosion and the battle. 

This blog post is dedicated to those sons of South Carolina who did not return home, but will always be remembered so long as there are those who are determined never to forget their memory.

Caleb Glover & Colonel Olin M. Dantzler C.S.A. -- United Confederate Veterans

Mr. Caleb Glover was born into slavery sometime around 1827 in St. Matthews, South Carolina to the Dantzler family of Calhoun County. He was both the slave and the life-long friend of the Dantzler family's oldest son, Olin Miller Dantzler, born on January 14, 1825.

As the two boys grew up together Dantzler secretly taught Caleb how to read and write (something that was against the law at the time in South Carolina).

To those in the Dantzler family and community, he was known as "Uncle Caleb". Those who knew Caleb described him as truthful, reliable, and one who never used foul language. His given last name Glover would later be taken from the surname of Olan Dantzler's wife, Caroline Anne Glover.

Olan Dantzler served as a South Carolina representative prior to the American Civil War (1861-1865) and reluctantly spoke out against secession until December 20, 1860 when the State formally seceded from the Union.

When the War Between the States broke out in 1861, Dantzler volunteered and was made Lieutenant Colonel of the 20th South Carolina Infantry on January 11, 1862 when the regiment was organized in Orangeburg, South Carolina.

Some conflicting accounts exist as to Caleb's legal status at the time with some suggesting he was still a slave, and others suggesting he was a free man of color and voluntarily accompanied Olan to war.

One of those accounts has Olan formally manumitting (freeing) Caleb and giving him a choice to go with him, or stay with the family; to which the older man, never one to leave his childhood friend and former master's side, choose to come along as Olan's "manservant" (body servant).

The regiment was assigned to the 2nd Military District of South Carolina, Department of South Carolina, Georgia and Florida. On March 4, 1862 the 20th South Carolina Infantry was stationed on James Island near Charleston, South Carolina near Secessionville.

Caleb and Olan and the 20th South Carolina would see their first action on April 7, 1862 when four companies of the regiment withstood bombardment from Union ironclads on Sullivan’s Island and while manning the siege guns on Battery Marshall.

Between July and August of 1863, the 20th South Carolina would suffer 33 casualties (9 killed, 24 wounded) while serving on picket duty on Morris Island, South Carolina.

When returning by steamer from Morris Island on August 30th the nearby Confederate batteries misidentified their boat as a Yankee ironclad and the regiment briefly came under fire, resulting in 16 of their number either killed outright, or drowned in Charleston harbor -- ironically losing men to "friendly fire" than to enemy action.

The 20th South Carolina was again stationed at Battery Marshall on Sullivan's Island in Charleston harbor in early 1864 when the Confederate submarine H.L. Hunley was stationed and being readied for its fateful mission. While there, Caleb Glover -- along with other servants -- probably helped prepare meals for the rest of the garrison, including the Hunley crewmen.

According to history, it was Colonel Dantzler, with Caleb likely by his side, that spotted the "blue light signal" signaling that the Hunley had completed its mission on the night of February 17, 1864 sinking the Union ship USS Housatonic -- the first submarine to successfully destroy an enemy vessel in naval history.

The Hunley never returned to port and sank in the harbor.

Dantzler's report to his commanding officer, Confederate General P.G.T. Beauregard, reads as follows:

HEADQUARTERS BATTERY MARSHALL, Sullivan’s Island, February 19, 1864.
"I have the honor to report that the torpedo boat stationed at this post went out on the night of the 17th instant (Wednesday) and has not yet returned. The signals agreed upon to be given in case the boat wished a light to be exposed at this post as a guide for its return were observed and answered…"

At the end of April of 1864, Olin Dantzler was promoted to Colonel and reassigned to command the 22nd Regiment South Carolina Infantry, which was stationed near Fort Moultrie, also on Sullivan's Island. Caleb accompanied him as well.

The regiment was then sent to Northern Virginia and took part in the Bermuda Hundred Campaign in May of 1864 near the Confederate capital at Richmond, Virginia.

On June 2, 1864, General Beauregard sent troops towards Union positions to discover their strength. Colonel Dantzler, with Caleb at his side, led the 22nd South Carolina Infantry Regiment in an attempt to capture Fort Dutton.

As the Confederates emerged from a ravine within 150 yards of the fort, cannons of the 1st Connecticut Heavy Artillery Regiment fired canister shot, killing 16 of the Southerners. Colonel Olin Danzler was mortally wounded as a piece of shrapnel hit him in the chest. He died on the battlefield in the arms of his friend, Caleb.

Caleb Glover recovered Colonel Danzler's body and returned with it, and the survivors of the assault, to Confederate lines. On June 13, 1864, General Beauregard issued General Orders No. 12 naming a Confederate fort near the James River Battery Dantzler in the colonel’s honor.

Caleb also recovered the body of Colonel Laurence M. Keitt, commander of the 20th South Carolina Volunteer Infantry Regiment who was also from St. Matthews. 

The three men: Glover, Dantzler and Keitt grew up near each other in South Carolina. Dantzler and Keitt were political rivals with Keitt being a known Fire-Eater who supported secession. Prior to the war, their political disagreements even led to a duel in which Keitt was wounded.

Ironically, both men would die on the same day within miles of each other in Virginia on June 2, 1864, (Keitt at Cold Harbor and Dantzler in Chesterfield). Kiett was mortally wounded during his first  (and only) field command while leading his infantry on a horse in a charge against Philip Sheridan's dismounted cavalry near Beulah Church when he was shot in the liver, or lung, and collapsed on the field.

Caleb recovered Colonel Keitt's body at night under the cover of darkness, barely avoiding Yankee pickets.

With his part in the war seemingly over with, Caleb Glover borrowed a wagon and took the bodies of his childhood friend, Colonel Dantzler and Colonel Keitt home to St. Matthews, South Carolina and remained there to comfort Dantzler's family until the end of the war in April of 1865.

Colonel Olan M. Dantzler is buried in a family plot at Tabernacle Cemetery in St. Matthews next to his parents and his wife, who would die later the same year on October 17th.

After the war, Judge Charles Glover Dantzler (1854-1919), the eldest of Col. Dantzler’s five sons, took care of the elder Glover for the remainder of his life.

Caleb Glover was recognized by those who served with him as a Confederate Veteran and awarded the Southern Cross of Honor medal for that service from the Paul McMicheal Chapter, United Daughters of the Confederacy for his service -- a medal Glover wore with pride to reunions of the United Confederate Veterans until his death on March 25, 1920 at age 93.

Caleb Glover is buried at the Bethel AME Church Cemetery in St. Matthews, South Carolina. His gravestone was restored and is currently maintained by the Colonel Olin M. Dantzler Camp #73 Sons of Confederate Veterans.
