On this day in 1864, a Federal counterattack saved the day in Atlanta. Who was artillery Capt. DeGress, a hero depicted in the Cyclorama?

If you are familiar with the Battle of Atlanta Cyclorama, the first image likely to come to mind is the brick Troup Hurt house, scene of a brief Confederate breakthrough during the fighting of July 22, 1864 -- 157 years ago today.

While the 370-foot circumference painting has dozens of small scenes and thousands of figures, the house is clearly the focal point of the battle – misinterpreted for years by its Southern promoters as showing a Rebel victory. Instead, something big is about to happen that will ensure this day will, in fact, see a Federal triumph.

Galloping furiously to the rescue, hat in hand, is Maj. Gen. John A. “Black Jack” Logan, head of the Army of the Tennessee. Behind him is Capt. Francis DeGress, whose artillery battery had been overrun shortly before.

“It is the point at which the 15^th Corps is pushed back. Like a rubber band, it springs back,” says Gordon Jones, senior military historian at the Atlanta History Center (AHC), which houses the mammoth work of art.

DeGress, already a respected veteran, is about to become a folk hero to the Northern cause. He retakes the four 20-pounder Parrott guns and turns them on the retreating Confederates.

“He is an example of the sort of mid-level officer who was a natural leader, on whom the troops really came to depend. On whom the battle depended,” said Jones, adding it is the privates, sergeants, lieutenants and captains who are controlling the battle.

Exhibits at the AHC include several DeGress artifacts, including a saber he likely carried that day, a Pond revolver he purchased a few months before the battle, a 15^th Corps badge and a bit that was used by one of the battery’s horses during the fighting. They were donated by family members. The AHC has papers related to DeGress at its Kenan Research Center.

The German-born artilleryman, commander of Company H, 1^st Illinois Light Artillery, was a veteran of several campaigns by the time he arrived in Atlanta. The 23-year-old’s battery was deployed in a vulnerable part of the Union line, east of the city and near a railroad line. (Sketch of DeGress, left, appeared in Harper's Weekly)

At 4 p.m. on July 22, the battery was firing canister as fast as it could. The determined Confederates continued to push forward and were about to be upon them.

DeGress knew the horses could not pull back the guns in time, Jones said, and he had two guns spiked. The captain and Sgt. Peter Wyman stayed with the other two weapons, firing double canister. They eventually had to flee; Wyman was killed while DeGress fled back to the collapsed Federal line.

Fast-forward to the scene depicted in the cyclorama: Logan rallying his troops and rushing toward the breach. DeGress soon regains possession of the battery and gets back into the action.

The painting also depicts the death of horses that pulled guns, caissons and limbers for Company H.

“You are seeing in the painting the Confederates are killing the horses because they are about to be overrun,” says Jones. But there’s a chance that DeGress ordered some of them be shot before his retreat. It was not unusual occurrence, because armies did not want their own guns used against them.

“Perhaps the mostly skillfully rendered figures in the painting are the horses,” says Jones. “The closest the artists got to real horror, they are showing them writhing in agony.”

Among the German and Austrian artists who created the cyclorama in 1886 was Albert Richter. He painted the horses based on sketches made at a Milwaukee slaughterhouse, where he apparently paid to use dying horses as models.

Harper’s Weekly illustrator Theodore R. Davis is largely responsible for DeGress being depicted in the painting. Davis, who traveled with the Federal army, submitted an illustration and article for the publication about the officer soon after the battle and served as an advisor to the artists in Milwaukee.

DeGress’ battery took part in the March to the Sea after Atlanta and the campaigns in South Carolina and North Carolina, and was present at the surrender of Confederate Gen. Joseph E. Johnston near Durham in April 1865.

After the war, the soldier went into business in Mexico, with a firearms company among his ventures. He died in 1883 – three years before the cyclorama was painted -- in Mexico City and is buried there.

Charlie Crawford, president emeritus of the Georgia Battlefields Association, said it is clear DeGress was highly regarded by superiors, subordinates and fellow artillery commanders.

“One measure of this regard is how quickly he was able to reconstitute his battery (H, 1st Illinois) after his guns were reclaimed on 22 July 1864,” says Crawford. “This is a testament to his own leadership and to how readily the other artillery batteries provided horses, harnesses, limbers, caissons and other equipment.”

The cyclorama shows the moment Alabama and South Carolina troops in Brig. Gen. Arthur Manigault’s brigade punctured the Union line. The AHC has the saber Manigault carried that day.

The Troup Hurt house is long gone. A church was built on the site, and now that structure is a private residence.

It’s important to note the battlefield on July 22 was much larger than what is shown in the painting. For example, troops clashed for a much longer time on Bald (Leggett’s) Hill south near current Interstate 20.

By evening, Confederate troops under Gen. John Bell Hood were repulsed with heavy losses. Fighting continued in and around Atlanta for several weeks, until the Rebels evacuated and the city fell.

Among the clashes was the little-known battle at Utoy Creek. From late July to late August, Federal troops made several thrusts toward the vital Rebel rail line in nearby East Point. Ultimately, victory had to come elsewhere.
