A Revolution in Killing: The Rifled Musket and the Minié Ball


Claude Minié

Friends of Padre Steve’s World,

I have continued to work on my various Gettysburg and Civil War texts and today something from one of them that should appeal to those interested in Civil War infantry weaponry and tactics.  I have to admit that I am kind of a geek about this kind of stuff but in order to understand the broad brush aspects of history one also has to know something about detailed facts. So anyway, here is a section of my text dealing with the advances in weaponry that made the American Civil War and subsequent wars so much more deadly.

Minié Ball 

While various individuals and manufacturers had been experimenting with rifles for some time the weapons were difficult to load as the rifled groves slowed down the loading process. The British pioneered the use of the rifle during the Napoleonic Wars and the War of 1812. The issue of the Baker rifle, a rifled flintlock which was accurate to about 300 yards was limited to specific Rifle Regiments which were considered elite units, as well as skirmishers in some other regiments. The soldiers assigned to the Rifle regiments wore a distinctive green uniform as opposed to the red wore by the rest of the British Army. When the United States Army formed its first Sharpshooter regiments in late 1861 under the command of Colonel Hiram Berdan. Like the British the men of the regiment as well as the 2nd Regiment of Sharpshooters wore a distinctive green uniform instead of the Union Blue.

In 1832 a captain Norton of the British Army “invented a cylindroconoidal bullet. When fired, its hollow base automatically expanded to engage the rifling of the barrel, thus giving the bullet a horizontal spin.” [1] But the bullet was unwieldy, so it and other bullets that were “large enough to “take” the rifling was difficult to ram down the barrel” and slowed down the rate of fire significantly, and since “rapid and reliable firing was essential in a battle, the rifle was not practical for the mass of the infantrymen.” [2]

In was not until 1848 when French Army Captain Claude Minié who “perfected a bullet small enough to be easily rammed down a rifled barrel, with a wooden plug in the base of the bullet to expand it upon firing to take the rifling.” [3] Unfortunately the bullets were expensive to produce and it was not until in 1850 an American armorer at Harpers Ferry, James Burton “simplified the design that had made Minié famous and developed a hollow based, .58-caliber lead projectile that could be cheaply mass produced.” [4] Burton’s ammunition was very easy to load into weapons, and soldiers were able to drop the cartridge into the muzzle of their rifles as easily as they could musket balls down a smoothbore.

The tactics the officers were educated in were developed at a time when the maximum effective range of muskets was barely 100 yards. However, the Army did make some minor adjustments to its tactics to increase speed and mobility in the tactic movement of the infantry. Colonel William J. Hardee went on to become a Confederate General adapted changes first made by the French to the U.S. infantry manual. These changes “introduced double-quick time (165 steps per-minute) and the run and allowed changes to the order of march to be made in motion rather than after coming to a halt.” [5]

During Napoleon’s time assaulting an opponent with a large body of troops was a fairly easy proposition, one simply maneuvered out of the rage of the enemy’s artillery and muskets, thus “to bring a heavy mass of troops upon them was possible because of the limited destructiveness of smoothbore firearms. Their range was so restricted that defenders could count on getting off only one reasonably effective volley against advancing soldiers. By the time that volley was unloosed, the attackers would be so close to their objective that before the defenders could reload, the attacking troops would be upon them.” [6] One of Napoleon’s favorite tactics was for his troops to make well executed turning maneuvers aimed at the enemy’s flanks, but the increased range and lethality meant that even when such maneuvers were executed, they often produced only a short term advantage as the defenders would form a new front and continue the action.

Yet by 1860 the rifled muskets had an effective range of about 500 yards and sometimes, depending on the type of weapon even more, but in most cases during the Civil War infantry engagements were fought at considerable shorter ranges. Paddy Griffith notes that even in the modern era long range firing by infantry units is still rare, and that there is “a fallacy in the notion that longer range weapons automatically produce longer-range fire. The range of firing has much more to do with the range of visibility, the intentions of the firer and the general climate of the army.” [7] Drew Gilpin Faust wrote that Civil War battles still “remained essentially intimate; soldiers were often able to see each other’s faces and to know who they had killed.” [8] They knew their weapons could fire at longer range, and one Union soldier explained, “when men can kill one another at six hundred yards they would generally would prefer to do it at that distance.” [9] But for the average infantryman such occasions were the exception.

The advent of the breach loading and later the repeating rifle and carbine further increased the firepower available to individual soldiers. However, with the exception of the Prussian Army, armies in Europe as well as the United States Army were slow to adapt the breech loading rifles. In “1841 the U.S. Arsenal at Harpers Ferry, Virginia, had prepared the pattern weapons of the first general-issue rifled shoulder arm of the U.S. Army” [10]

The process of conversion to the new weapons was slow, conservatism reigned in the Army and the lack of suitable ammunition was a sticking point. However, the U.S. Army began its conversion “to the rifled musket in the 1840s but rejected both the repeating rifle and the breechloader for infantry because of mechanical problems.” [11] Even so there was a continued resistance by leaders in the army to arming infantry with the rifled muskets despite the already noted obsolescence of them during the Crimean War. In discussing the differences of rifles and smoothbore muskets during the Peninsular Campaign, Edward Porter Alexander wrote that “In the Mexican War fought with smooth bore, short range muskets, in fact, the character of the ground cut comparatively little figure. But with the rifles muskets & cannon of this war the affair was proven both at Malvern Hill, & at Gettysburg….” [12]

However, in 1855 the new Secretary of War, Jefferson Davis ordered the Army to convert to “the .58 caliber Springfield Rifled Musket. Along with the similar British Enfield rifle (caliber .577, which would take the same bullet as the Springfield), the Springfield became the main infantry arm of the Civil War.” [13] Even so the production of the new rifles was slow and at the beginning of the war only about 35,000 of all types were in Federal arsenals or in the hands of Federal troops.

The one failure of Union Chief of Ordnance Ripley was his “insistence in sticking by the muzzle loading rifle as the standard infantry arm, rather than introducing the breach-loading repeating rifle.” [14] Ripley believed that a “move to rapid fire repeating rifles would put too much stress on the federal arsenals’ ability to supply the repeaters in sufficient quantities for the Union armies.” [15] There is a measure of truth in this for troops armed with these weapons did have the tendency to waste significantly more ammunition than those armed with slow firing muzzle loaders, but had he done so the war may not have lasted nearly as long.


Had Ripley done this Union infantry would have enjoyed an immense superiority in sheer weight of firepower on the battlefield. The noted Confederate artilleryman and post-war analyst Porter Alexander believed that had the Federals adopter breech loading weapons that the war would have been over very quickly, noting, “There is reason to believe that had the Federal infantry been armed from the first with even the breech-loaders available in 1861 the war would have been terminated within a year.” [16] Alexander’s observation is quite correct. As the war progressed and more Union troops were armed with breach loaders and repeaters Confederates found themselves unable to stand up to the vastly increased firepower of Union units armed with the newer weapons. A Union soldier assigned to the 100th Indiana of Sherman’s army in 1865:

“I think the Johnnys are getting rattled; they are afraid of our repeating rifles. They say that we are not fair, that we have guns that we load up on Sunday and shoot all the rest of the week. This I know, I feel a good deal confidence in myself with a 16 shooter in my hands, than I used to with a single shot rifle.” [17]

During the war both the Union and Confederate armies used a large number of shoulder-fired rifles and muskets of various manufactures and vintage. This was in large part because of a shortage of the standard M1861 Springfield Rifled Musket at the beginning of the war and initially standardization was a problem, and as a result many units went to war armed with various types of weapons which made supply, training, and coordinated fires difficult. At the beginning of the war, the Federal government had only about 437,000 muskets and rifles in its inventory, and only about 40,000 of these were rifled muskets, either older weapons converted from smoothbores or the newly manufactured Springfield rifles.

The disparity of types of weapons that might be found in a single regiment contributed to difficulties in supplying ammunition to them, and proved to be nightmarish for experienced quartermasters. This was especially the case when the amateur quartermasters of many regiments did not specify exactly what types of ammunition they required.

Likewise, in addition to the existing stocks of weapons available for use, the Federal government only had two armories capable of manufacturing arms, Harpers Ferry Virginia, which had to be abandoned in 1861 when Virginia seceded from the Union, and the other in Springfield Massachusetts, which had a capacity to manufacture between 3,000 and 4,000 rifles a month. Ordnance Chief Ripley solved that problem by contracting with U.S. and foreign manufacturers to make up for what government armories could not do. In the first year of the war he contracted for nearly 750,000 rifles from U.S. and foreign arms suppliers. During the war he expanded the capacity at Springfield so that it could produce over 300,000 weapons a year. Even so at Gettysburg sixty-five of the 242 Union infantry regiments, some 26%, were fully or partially armed with older substandard weapons, both smoothbores and antiquated rifles. In 1863 and 1864, the Confederate Army of the Tennessee over half of the army was armed with smoothbores or antiquated rifles. [18]

But the initial shortage of weapons caused problems for both sides. The Confederacy had to make the best use of what they had obtained in captured federal depots at the beginning of the war, which amounted to 140,000 smoothbores and another 35,000 rifled muskets.  Like the Federal Government, the Confederacy which had much less industrial capacity was forced to purchase many of its weapons from England expending badly needed capital to do so and requiring the weapons to be shipped through the Union blockade on blockade runners operating from England, the Bahamas, or other English Caribbean possessions. During the war the Confederates purchased approximately 300,000 rifled muskets and 30,000 smoothbores from Europe while producing just over 100,000 shoulder fired weapons of all types during the war. The Union through its economic superiority was able to acquire a million rifled muskets, 100,000 smoothbores from Europe in addition to the 1.75 million rifled muskets, 300,000 breechloaders, and 100, repeaters of its own wartime manufacture. [19]

In the end the disparity in quality and quantity of arms would doom the élan of the Confederate infantry in battle after battle. Porter Alexander wrote of the Confederate equipment situation:

“The old smooth-bore musket, calibre 69, made up the bulk of the Confederate armament at the beginning, some of the guns, even all through 1862, being old flint-locks. But every effort was made to replace them by rifled muskets captured in battle, brought through the blockade from Europe, or manufactured at a few small arsenals which we gradually fitted up. Not until after the battle of Gettysburg was the whole army in Virginia equipped with the rifled musket. In 1864 we captured some Spencer breech-loaders, but we could never use them for lack of proper cartridges.” [20]

The number of kinds of weapons that a given unit might be equipped was difficult for commanders and logisticians on both sides.  For example, Sherman’s division at the Battle of Shiloh “utilized six different kinds of shoulder arms, with each necessitating a different caliber of ammunition,” [21] which caused no end of logistical problems for Sherman’s troops as well as other units equipped with mixed weaponry.

While this increase in range, accuracy, and rate of fire were important, they were also mitigated by the fact that the smoke created by the black, non-smokeless gunpowder powder expended by all weapons during the Civil War often obscured the battlefield, and the stress of combat reduced the rate and accuracy of fire of the typical soldier. This was compounded by the fact that most soldiers received little in the way of real marksmanship training. Allen Guelzo notes that the “raw inexperience of Civil War officers, the poor training in firearms offered to the Civil War recruit, and the obstacles created by the American terrain generally cut down the effective range of Civil War combat to little more than eighty yards.” [22] That being said well-drilled regiments engaging enemy troops in the open on ground of their choosing could deliver devastating volley fire on their enemies.

But the real increase in lethality on the Civil War battlefield was the Minié ball “which could penetrate six inches of pine board at 500 yards.” [23] as such, the bullet was decidedly more lethal than the old smoothbore rounds, and most wounds “were inflicted by Minié balls fired from rifles: 94 percent of Union casualties were caused by bullets.” [24] The old musket balls were fired at a comparatively low velocity and when they hit a man they often pass through a human body nearly intact, unless there was a direct hit on a bone. Thus wounds were generally fairly simple to treat unless a major organ or blood vessel had been hit. But the Minié ball ushered in for those hit by it as well as the surgeons who had to treat their wounds:

“The very attributes that increased the bullet’s range also increased its destructive potential when it hit its target. Unlike the solid ball, which could pass through a body nearly intact, leaving an exit would not much larger than the entrance wound, the soft, hollow-based Minié ball flattened and deformed on impact, while creating a shock wave that emanated outward. The Minié ball didn’t just break bones, it shattered them. It didn’t just pierce organs, it shredded them. And if the ragged, tumbling bullet had enough force to cleave completely through the body, which it often did, it tore out an exit wound several times the size of the entrance wound.” [25]

When these bullets hit the arm and leg bones of soldiers the effects were often catastrophic and required immediate amputation of the limb by surgeons working in abysmal conditions. “The two minie bullets, for example, that struck John Bell Hood’s leg at Chickamauga destroyed 5 inches of his upper thigh bone. This left surgeons no choice but to amputate shattered limbs. Hood’s leg was removed only 4 and 1/2 inches away from his body. Hip amputations, like Hood’s, had mortality rates of around 83%.” [26]

This technological advance changed the balance and gave armies fighting on the defensive an edge. The advance in the range and killing power embodied in the rifled musket made it especially difficult for the armies that fought the Civil War to successfully execute frontal assaults on prepared defenders. The defensive power was so enhanced that even a “well executed turning maneuver was likely to produce only a decidedly temporary advantage in the Civil War.” [27] Well trained units could change their front against enemies assailing their flanks and turning them back as was demonstrated by Joshua Chamberlain’s 20th Maine at Little Round Top. Occasionally some assaulting troops would get in among the enemy’s lines, despite the enormous costs that they incurred during their attacks, but “the greater problem was how to stay there and exploit the advantage once the enemy’s line had been pierced. Almost invariably, by that time the attacker had lost so heavily, and his reserves were distant, that he could not hold on against a counterattack by the defending army’s nearby reserves.” [28]

Despite the increased range of the rifled muskets many infantry firefights were still fought at closer ranges, usually under 200 yards, not much more than the Napoleonic era. Much of this had to do with the training of the infantry as well as visibility on the battlefield which in North America was often obscured by heavy forested areas and thickets in which armies would battle each other at close range. Battles such as the Seven Days, Chancellorsville, and much of the Overland Campaign were fought in such terrain.

This was demonstrated time and time again throughout the course of the war as commanders attempted frontal assaults on such positions. “The only way to impose heavy enough casualties upon an enemy army to approximate that army’s destruction was to accept such heavy casualties oneself that no decisive advantage could accrue.” [29] Lee’s assault on Malvern Hill and his numerous frontal assaults on prepared positions at Gettysburg, Burnside’s ghastly assaults at Fredericksburg, Grant’s first attack at Vicksburg, and Grant’s ill-advised attack at Cold Harbor demonstrated the futility and ghastly cost of such tactics. The ability of infantry in the assault to “rise up and deliver a frontal attack became almost always futile against any reasonably steady defenders. Even well executed flank attacks tended to suffer such heavy casualties as experienced riflemen maneuvered to form new fronts against them that they lost the decisiveness they had enjoyed in the Napoleonic Wars.” [30] During the Wilderness Campaign battles were fought for hours on end at point blank range amid heavy woods and fortifications.

As important as the rifled muskets were, the real revolution in battlefield firepower was brought about by the repeating rifles and muskets which came into use during the war. The early examples were not reliable because the ammunition available was in a paper cartridge which sometimes caused gas and flames to escape form the breach, making the weapon dangerous to the user. But this was corrected with the introduction of brass cartridges and later weapons became deadly instrument. Because of its range as compared to the older smoothbores, the rifled musket “added a new spatial dimension to the battlefield,” [31] but the repeating rifles, which had a shorter range than the rifled muskets looked forward to the day of semi-automatic and automatic weapons. The repeaters could “pump out so many shots in such a short time that it offered a new perspective in tactical theory from that used by the old carefully aimed one-shot weapons,” and added “a new temporal dimension to the close range volley.” [32]

Despite the fact that leaders knew about the increased range and accuracy that came with the rifled musket, tactics in all arms were slow to change, and “on every occasion, a frontal assault delivered against an unshaken enemy led to failure.” [33] Even at Gettysburg Robert E. Lee would demonstrate that he had not fully appreciated the effects of the lethality of the rifled musket when he ordered Hood’s assault on Federal troops at Little Round Top on July 2nd and Pickett’s assault on the Union center on July 3rd 1863. Lee should have learned during the bloody battles of 1862 and early 1863 which cost his army over 50,000 casualties.

    …a good (if sombering) read Padre…sometime (if you have not already)…touch on the important (and mundane) topic of logistics…

  2. DonM

    …a not real good book is “The Logistics of Waging War”, Air Force Logistics Management Center, 1989..but it contains a list of good references…if I could only obtain them…
