At Andersonville and elsewhere, crossing the 'deadline' meant death. Whatever the number of incidents, the existence of these barriers kept men in line

Before the word deadline became synonymous with getting something done by a specific time, it was associated with a deadly feature of Civil War prisons. A captive crossing the deadline risked death, and there are instances of guards on both sides shooting them.

The deadline was intended to prevent the prison’s growing population from getting too close to the stockade wall, making escape more difficult. It was also supposed to reduce fraternization and trading between the prisoners and guards, according to the National Park Service.

Andersonville National Historic Site on Sunday marked the 160^th anniversary of the completion of the deadline at the site (April 7, 1864). Stockade commander Capt. Henry Wirz had made this a priority.

The light railing was made from posts 3 to 4 feet long and driven into the ground. Horizontal pieces of wood topped the design, which was roughly 18-19 feet inside the stockade wall.

Confederate guards in sentry boxes kept a sharp eye for POWs who extended any part of their body past the deadline. (Not all camps had such features).

The first Union POW to die at Andersonville for crossing the deadline was Caleb Coplan (Copeland), a young Ohioan shot just two days after it was completed.

The prisoner was wandering the northeast corner of the stockade, apparently in search of material to patch his shelter or clothing, wrote William Marvel in “Andersonville: The Last Depot.” (Photo at left courtesy of John Banks' Civil War Blog)

“Something under the dead line caught his eye -- a scrap of flannel, some said -- and he ducked under the line to retrieve it. The guard brought his cumbersome old smoothbore to his shoulder and let fly with a charge of buck-and-ball. The range was too short to miss, and the .75-caliber ball bored through Coplan’s breast near the heart. Onlookers carried him to the hospital tents a few yards away, where he died the next day -- the first man killed at the dead line.” (Photo below of his grave at Andersonville courtesy of Kevin Frye.)

There would be more to come, at Andersonville and other prisons. Archaeology at Camp Lawton near Millen, Ga., has uncovered two Confederate bullets possibly fired at captives.

Those who have researched these prisons express caution about try to tabulate the number of shootings at the deadline.

Prisoners often exaggerated the number; at Andersonville this claim amounted to hundreds. “Sometimes this was done on purpose and sometimes they were simply mistaken or remember incorrectly,” says Teri A. Surber, park guide at Andersonville.

Regardless of where they occurred, shootings at the deadline had a profound psychological impact on POWs.

Surber and Michael Gray, a history professor and author of “Crossing the Deadlines: Civil War Prisons Reconsidered,” said Union prisoners might receive more pension money by showing they suffered during confinement. There was an incentive to lie about being a prisoner or witnessing horrific incidents, they say.

Bob Crickenberger, president of the Friends of Point Lookout (a Union prison in Maryland), said people should be leery of  hearsay stories told years after the war, particularly those that begin with, “I was told”, “I heard,” or “it’s been said.”

“Unless a prisoner was there and was an eyewitness to the shooting, and there were many witnesses, should (a story) be taken as truth. Kind of like all those folks that said Sherman burned their farms when they were miles out of the way when he came through.”

Was this .57-caliber bullet fired at a POW at Camp Lawton? (Georgia Southern U.)

Gray notes that in the last two years of the war, prisoners were often manned by older, extremely young or disabled soldiers and training was an issue. “You are going to send the best men to the front.”

By any measure, life in a Civil War prison was marked by privation and despair. Matters worsened after prisoner exchanges ended by mid-war, resulting in a huge increase in camp populations on both sides.

Between the skill of the guards and the desperation of prisoners, there are documented cases of shootings at the deadline or elsewhere in a camp. Firm numbers are impossible to ascertain, but here’s a look at several, including Elmira, Camp Lawton and Point Lookout:

ANDERSONVILLE/CAMP SUMTER (Georgia – Confederate camp)

At Andersonville alone, nearly 13,000 men died over 14 months – an average of more than 30 a day in that span. (Overall, 30,000 Union and 26,000 Confederate soldiers died in captivity during the Civil War). A relative few were shot by guards.

“Drawings of men being shot at the deadline were widely reprinted in Northern newspapers, and today, the term is almost synonymous with Andersonville prison,” according to the NPS.

Surber said there are eight documented cases of a guard shooting a prisoner.. A firm number will likely never be known.

"The only time guards shot at prisoners was when they crossed the deadline or if someone near them crossed it. There is an instance where a man reached over the line to get something, and the guard accidentally shot the man sleeping next to him," the park guide says.

(If someone had a gunshot wound from a battle, they were usually listed as having died of "wounds.")

“One confirmed shooting that I would say was the (wounding) of a man the prisoners called ‘Chickamauga.’ Robert Kellogg and several others wrote about the incident in their diaries or memoirs and also testified about it during the (Henry) Wirz trial. Another is Pvt. William Stewart, 9^th Minnesota Infantry, whose cause of death is recorded as ‘gunshot.’"

During the trial, prisoner George Gray testified that Wirz himself shot Stewart and took some money from him. Wirz (left) denied anything to do with Stewart. “There were rumors that guards were given a 30-day furlough for shooting a prisoner, but there is no actual evidence of that,” Surber says, adding there is no evidence Wirz shot prisoners.

Albert Harry Shatzel of the 1^st Vermont Cavalry wrote that he saw a shooting at the deadline.

“One of the poor Boys shot dead by Guard while geting a cup of watter,” Shatzel wrote, according to Civil War blogger John Banks. “The Ball passed through his head. He stuck his head under the Dead Line to get some watter but he will never go there again. Dam the laws of such men as those are hear for they consider it an honor to murder a man …all in all they are not to blame for they a Furlough of 35 days for every man they kill.”

Surber provided a list of the rare successful escapes at Andersonville.

None of the 33 dug out from the inside; they were already outside or on a work detail when they made a break for freedom.

“The answer to how many were shot while trying to escape is fairly easy,” Surber says. “None, as far as we know. All eight of these men were shot for crossing the deadline and were inside the prison. Of course, it is possible that someone could have been shot while trying to escape, as would be the practice of the day, but there is no way to know for certain.”

CAMP LAWTON (Georgia – Confederate camp)

Camp Lawton operated for about six weeks in the fall of 1864. Prisoners were sent from Andersonville amid worries Union raiders would try to liberate the camp. Of 10,000 troops held at Lawton, at least 750 Federal soldiers died.

Ryan McNutt, director of the Camp Lawton archaeological project at Georgia Southern University, said historical sources are not complete enough to come up with a full count of POWs shot by guards.

“As ever, there are confused and scattered references,” he tells the Picket. “(POW John) McElroy states that he couldn't recall anyone being shot at Lawton for crossing the deadline, and he raised it as a curiosity since every other camp he was at had at least a few instances of executions by guards. However, Cpl. Aldrich said, ‘Once in a while the guards would shoot a poor fellow just to keep his hand in it, still, there was not as much shooting as at Andersonville. One poor fellow was shot within 10 feet of my tent one night and he was not within 10 feet of the deadline.’"

John K. Derden, author and professor emeritus of East Georgia College, said while there are diary accounts mentioning shootings, he found only one incident that was seemingly corroborated. Regardless, there were fewer shootings than at Andersonville.

James Vance wrote in his diary for Nov. 6, 1864). “2 men shot 1 killed. The first ones.” Sgt. Amos Yeakle wrote in his diary the same day, “There was one shot dead by the guard and one wounded for getting over the dead-line.”

Derden, author of “The World’s Largest Prison: The Story of Camp Lawton,” contends prisoners might hear a guard firing to clear a musket and assume the round was meant for a Federal soldier.

“As for the climate in the prison, I believe that things were a bit less fractious because of the lack of overcrowding, the water situation that allowed prisoners to bathe and even swim, and (at least initially) the somewhat better food supply. Also, Commandant Vowles was generally well liked by the prisoners as opposed to their bitter attitudes toward Wirz at Camp Sumter.”

Regarding the deadline, archaeology seems to indicate about a 30-foot clear space between shebang remains and the wall, says Derden.

McNutt said students have recovered at least two Confederate bullets that may have been fired at the inside of the Lawton stockade. The team in early 2023 found a poorly cast ball, likely fired from a Springfield Model 1842 percussion cap musket (photo below, courtesy of Camp Lawton project).

“Produced in large numbers, and floating around most of the arsenals in the South, these were still used despite the lack of accuracy and range in both the front lines and on the home front by militia. With a maximum range of 365 meters, and an average effective range from 90 to 275 meters, the location of the ball is well within range of the guard towers. And while most of the POWs at Camp Lawton recalled few instances of guards shooting POWs, our fired musket ball, along with other fired rounds from previous work inside the stockade, is a sobering reminder that Lawton still had many ways to die,” the professor writes.

Students led by Lance Greene, his predecessor, in 2010 found a spent .57-caliber bullet at the stockade. The round “has clear signs of rifling from being fired: deformation on the tip seems to show it only striking sand, though this doesn't preclude it having impacted a human,” McNutt says

Later analysis showed three groves and a right-hand twist indicating it was probably fired from a Pattern 1853 Enfield rifled musket. “Deformation on the nose matches experimental archaeology of impacts into soft surfaces, like sand or loamy soil,” according to McNutt. 

ELMIRA (New York – Union camp)

Elmira did not have a deadline, even though it was a stockade prison. The camp was dubbed “Hellmira” by prisoners because of its 24 percent mortality rate. Gray said there are records of a Union guard shooting a Confederate prisoner.

According to the Star Gazette newspaper, Granville Garland shot A.P. Potts of the 38^th Georgia Infantry during a July 31, 1864, disturbance. Potts survived.

Inmates at Elmira weathered hunger, illness and melancholia and, even worse, exposure to the cold weather, according to the National Park Service.

POINT LOOKOUT (Maryland – union camp)

The overcrowded prison saw 4,000 Confederate prisoners succumb to various causes, especially disease. Some were killed by guards, according to experts and histories. About 52,000 Union soldiers went through the prison.

The camp’s deadline was a ditch inside the prison approximately 15 feet from the parapet wall. The ditch was a foot wide by a foot deep.

Official records show African-American guards, some formerly enslaved, sometimes shot prisoners for crossing the deadline or trying to escape, says Gray. The prison is known for its racial tension.

“One commanding officer claimed that the black guards were more zealous than the white when it came to enforcement of prison regulations and were apt to fire first while calling for the corporal of the guard,” says Crickenberger.

He estimates 19 prisoners were shot and killed or wounded by white and black guards between November 1863 and August 1864 alone. Prisoners reported that there were instances where guards fired at prisoners without inflicting casualties. (Photo, Friends of Point Lookout)

“They shot frequently but missed more often than they hit,” Crickenberger says. “Regardless of the accuracy of the guard, such incidents kept prisoners on their toes making them wary and continually fearful of being shot either night or day.”

A Confederate prisoner drew notable watercolors of life at the prison, including interactions with guards. It should be noted that black POWs held at Andersonville faced discrimination from friend and foe alike.

The friends group has helped restore the fort, the southwest corner of the stockade and assists with living histories and demonstrations of camp life.

ROCK ISLAND (Illinois-Iowa – Union camp)

The deadline at Rock Island consisted of a series of white stakes (left, photo Rock Island Arsenal Museum) that were illuminated by lanterns at night, according to the NPS.

The barracks were enclosed by a stockade fence 1,300 feet long, 900 feet wide and 12 feet high. Sentry boxes were placed every 100 feet.

During the 20 months the prison was open, 1,960 prisoners and 171 Union guards died.

The North had reduced rations in retaliation for the treatment of Union prisoners at Andersonville. Conditions at Federal prisons often were deplorable.
