One of history’s longest sniper kills happened during the Civil War
Fort Sumter, South Carolina was famous for having suffered the first shots of the Civil War in April 1861. Over three years later, the two sides were still fighting over it. Confederate troops held the badly damaged fort while Union soldiers fired on it with artillery from batteries on nearby islands.
On Dec. 5 an unidentified Confederate soldier in Fort Sumter saw a Union soldier moving in Battery Gregg, 1390 yards away. The Southerner was likely using a Whitworth Rifle when he lined up his sights on the Union soldier and fired, killing him.
Whitworth Rifles are sometimes called the first real sniper rifle. Capable of accurate fire at 800 yards, its hexagonal rounds could penetrate a sandbag to kill an enemy standing behind it.
The rifle made the shot easier but the skill and luck needed to kill an enemy at 1,390 yards was still great. When the rifle was mounted on a special stand and tested at 1,400 yards, 10 shots created a grouping over 9 feet wide.
Unfortunately, the record-setting shot on Dec. 5, 1864 was illegal. The Confederate soldiers didn't know a ceasefire was in effect in the area and the shot violated that ceasefire. Other Confederate snipers at Fort Sumter took up the volley, forcing the Union troops to seek cover.
Fort Sumter in Sep. 1863 had already been subjected to two years of shelling by Confederate and then Union forces. After this photo was taken, it would suffer another year of shelling before the events of Dec. 5, 1864.
The Union soldiers endured the fire for an hour before they responded. They began firing cannons from the battery at Cummings Point, a group of cannons protected from retaliation by iron armor.
After an hour of shelling, the Confederates learned of the ceasefire and sent the Union general a very gracious letter of apology.
Both sides returned to the truce, but it didn't last. Charleston was still under siege and Union batteries soon resumed shelling the city. In mid-February 1865, Confederate troops withdrew from Fort Sumter and Charleston as Maj. Gen. William Tecumseh Sherman arrived on his famous march to the sea.
