Gunpowder weapons have been used in wars for hundreds of years, but for most of that time, they were highly inaccurate and were fired in the general direction of the enemy, relying on the mass volume of missiles used to inflict damage rather than being aimed at a specific target. This was particularly true for the individual weapons used by the common soldier.
Mass volleys were the attempt to compensate for lack of precision. Smoothbore muskets, used widely from the 16th to 19th centuries, had limited effective range (typically 50-100 yards) and poor accuracy that was due to the lack of rifling and inconsistent ammunition. Armies used tactics like line infantry volleys to maximize the impact of collective fire, aiming at enemy formations rather than at individual targets.
Colonel George Hanger served in the British Army during the American Revolution and later wrote:
"A soldier's musket, if not exceedingly ill-bored (as many are), will strike the figure of a man at 80 yards; it may even at 100 yards; but a soldier must be very unfortunate indeed who shall be wounded by a common musket at 150 yards, provided his antagonist aims at him; and as to firing at a man at 200 yards with a common musket, you may just as well fire at the moon and have the same hopes of hitting your object. I do maintain and will prove, whenever called on, that no man was ever killed at 200 yards by a common soldier's musket, by the person who aimed at him."
The British Brown Bess musket, used during the American Revolution, had only a simple round brass bead at the end of the barrel, with no rear sights. Soldiers were told not to aim the weapon, but to present it. Soldiers were drilled not for marksmanship, but simply for loading and firing the weapon as rapidly as possible.
The French infantry under Napoleon, for example, received limited training in live-fire practice due to logistical constraints, cost, and the greater focus on drilling for formation tactics. Training was more about maneuvering, reloading speed, and maintaining discipline under fire than about honing individual aiming skills.
The manner in which war was conducted in Europe decreed little need for a more accurate infantry weapon. Armies were seen as instruments of statecraft, and wars were often waged more for diplomatic leverage than for annihilation. Aristocratic officers were not present to participate in the fight directly, but to command the troops. The deliberate killing of such an officer—particularly by a sniper from concealment—was considered assassination, not combat. There was also the common belief that without the controlling hand of an aristocratic officer, the common soldiers would run amok, committing atrocities.
This understanding of war began to change by the end of the 18th century, particularly during the American Revolution, when better rifles meant that snipers could pick high value targets on the field—such as officers or the troops manning the artillery. Slowly, sniping began to be seen as an effective battlefield tactic rather than a war crime.
At the start of the 19th century, a few specialized units, like sharpshooters and riflemen, used early rifled firearms for more accurate, targeted shooting, though these were not the norm. The British Army began to form a few small units that were equipped with the Baker Rifle—a weapon that, while it was slow to load, was effective at ranges up to 200 yards.
Following this lead, while the American Army in the Mexican-American War still equipped the majority of the soldiers with muskets, a few of the soldiers were issued the 1841 Mississippi Rifle, a weapon that was accurate out to 300 yards. Military leaders were reluctant to adopt the rifles en masse because the weapons were slow to load and the longer barrels made them fragile.
At the start of the American Civil War, both the Union and the Confederate armies still relied on the old smoothbore muskets, with their limited effective range of only 50-100 yards. This rapidly changed during the war, as both armies began to use rifled muskets—weapons that were still breech-loaded, but whose rifled barrels allowed for greater accuracy when firing conical bullets such as the Minié ball. (Commonly called the Minnie Ball; one of my students wrote on a test that “Minnie Balls was a woman who fought in the war disguised as a man.”)
While these rifled muskets had a much greater effective range, there was still a need for a weapon with a much longer reach. For the Confederates, the gap was closed by the Whitworth Rifle, the first military sniper rifle. Manufactured in Great Britain, the Whitworth rifle was spectacularly accurate, with a maximum effective range of 1000 yards. (Some marksmen claimed this was a conservative estimate.)
Although it was still a muzzle-loading percussion rifle, the Whitworth rifle’s innovative hexagonal rifling and its precisely engineered ammunition made it significantly more accurate than a standard rifled musket. Unlike conventional rifles that used circular grooves, the Whitworth featured a hexagonal bore that matched the shape of its elongated bullet, allowing the projectile to fit tightly and spin consistently without deforming. This precise mechanical fit dramatically improved the stability, velocity, and trajectory of the bullet in flight. In addition, the Whitworth had a smaller bore (.451 caliber) and a tighter twist rate, which increased the bullet's spin and extended its effective range.
Each of these early sniper rifles cost the Confederacy approximately $400, the equivalent of about $10,000 today (and the cost was even more than that if the rifle was equipped with an early model telescopic sight). After purchase, each of the rifles had to be smuggled into the South, past the Union Army. These difficulties meant that the South only managed to import, at most, 150 Whitworth Rifles, which were issued to Confederate sharpshooter detachments who specialized in targeting officers and artillerymen from extreme distances.
The new sniper rifles proved to be effective not only in combat, but were effective in changing the behavior of Union officers. Since the specially shaped bullets produced a whistling sound as they passed, the Union knew that the South was using snipers, creating a growing fear of long-range sharpshooting, which forced changes in officer behavior and battlefield positioning — such as ducking, staying mounted less often, and using cover more carefully.
Occasionally, however, an officer would fail to realize that warfare was changing.
At the Battle of Spotsylvania Court House on May 9, 1864, the Union Army suffered one of its most stunning battlefield losses—not in terms of numbers, but in the death of one of its most respected commanders, Major General John Sedgwick. A veteran officer known for his calm demeanor and devotion to his men, Sedgwick commanded the Union VI Corps during General Ulysses S. Grant’s Overland Campaign. That morning, as Sedgwick prepared his artillery placements, Confederate sharpshooters armed with Whitworth rifles took up hidden positions nearly a thousand yards away.
As Sedgwick supervised his men near the front line, Confederate snipers began firing. Union soldiers instinctively ducked, prompting Sedgwick to chastise them. “What? Men dodging this way for single bullets? What will you do when they open fire with the whole line?” he scolded. Then came his final, now-famous words: “They couldn’t hit an elephant at this distance.”
Moments later, Sedgwick was shot beneath the left eye and died instantly. He was the highest-ranking Union officer to be killed in combat during the Civil War.
