I know, I should know this, but I don't. I knew the soldiers used guns but didn't think much more about it. (In a quick search of my book, I found more "rifle pits" than rifles and more "musketry" than "muskets.") I recently read (or re-read) The Red Badge of Courage, and I noticed the soldiers were just loading or reloading and firing, not aiming. So was the idea to just shoot in the direction of the opposing line and hope you hit someone? In other words, hitting someone or being hit was a matter of luck? They weren't trained to hit targets? It's not like aiming at an animal when you're hunting?
It is a trope that Civil War infantry did not engage in target practice. In the early months of the war, just getting organized was a 24/7 challenge. The majority of the raw recruits had never fired a long gun in their lives. The militia had been moribund for decades. At Perryville entire regiments had a baptism of fire before many of the men had loaded their muskets & fired a shingle shot.
In 1863 when the Army of the Cumberland advanced across an 80 mile wide front. Every firefight was a lopsided victory for the Cumberlanders. Only six months earlier when the 14th Army Corps marched out of Nashville on Boxing Day, 40% of the infantry was armed with a random collection of smoothbore muskets.
With smoothbore muskets at 200 & 100 yards there was no point in even pretending to aim. Many of the balls didn't even hit the target at those ranges. For good reason, Napoleonic firefights occurred at less than 100 yards.
With rifled muskets at 200, 300 & 500 yards, compare the results with 100 yards with a smoothbore. With a rifle soldiers could engage a target at five times the range of a smoothbore. At Stones River 60% of Bragg's infantry was armed with smoothbores. Some of them were little more than rusted out junk. All the poor slubs in Florida regiments where the lucky ones carried the hammer in a pocket lost 80% without inflicting a single casualty on Hazen's men defending the Round Forrest. The rear ranks were armed with sticks…
At 100 yards the average U.S. soldier was deadly accurate. That did not happen by accident.
On the rain drenched false dawn of June 23, 1863 Wilder's mounted infantry overwhelmed Wheeler's cavalry guarding the entrance to the one lane Hoover's Gap. At both the Gap & at Shelbyville on the right flank, Wheeler's rain soaked troopers could only get 4 out of 10 of their muzzleloaders to fire. Wilder's men & the regiment armed with seven shot Spencer rifles had regularly shot their barrels in at the rifle range where the Stones River VC is now.
Unlike a muzzleloader, the Spencer allowed the soldier to hold his sight picture as he reloaded.
Copper cartridges were not subject to being reduced to sludge by a 500 year rain event.
Of course, the majority of soldiers were equipped with obsolete muzzle loading muskets right up until the end of the war. My point here is that at the end of a three year enlistment the necessity of basic marksmanship was obvious to the weakest of minds. Soldiers who veteranized for the rest of the war knew their trade. Whether it was firing a Spencer across the Tennessee River to drive Bragg's sharpshooters away or Army of the Tennessee or Army of the Potomac pickets who went forward with 50 rounds to fire during their trick on the line, the conceit that they couldn't hit the broad side of a barn withers.
On a cool humid morning with no wind, "aimed shots" is a bit of a euphemism. 60% of a black powder load is ejected as solid particulate matter… thus the Civil War assaults at Gettysburg & Franklin disappearing into a boiling, blinding roil of white smoke. We know each other well enough to understand me when I say that here on CWT there are a lot posts by people who have never smelled a hint of powder smoke in their lives. It isn't an insult, it is just a fact. You asked a good question. I do wish you would come form up with us.
My wife Anne loved being at arms length of the muzzle as cannoneer #2. So many questions you have never asked would be answered. Here's one…
In the drill, #'s 1 & 2 observe the muzzle blast. It is counter intuitive, but in battery it isn't obvious whether your gun has gone off or not. The same was true of infantry firing in line. Even in the benign atmosphere of a national park, misfires can be questionable. In the Adrenalin soaked otherworld of a black powder firefight, muscle memory, not the rational mind, took over. With nerves twanging like a banjo, ten or more rounds loaded one after another were not unusual & perfectly understandable.
I believe you deserve a thoughtful reply to your question… hope this helps.
