The simple fact is that few of the city and town volunteers had ever held a rifle, never mind fired it. Yes, there were some natural marksmen, but most hadn't a clue what to do. Neither had their instructors. There were simply not enough instructors to go around, so they used the old guys. Most would have been familiar with the percussion musket - there were plenty available - but they were not trained in the military use of the rifle for line regiments. Yes, rifles had been issued before, but how many who had used them in the Mexican Wars were still around?
BTW, I don't think we were a nation of riflemen in 1775. We were a nation of shooters. Rifles were a rare thing in New England and most New Englanders used buck 'n ball. Where the Swiss/Germans settled there were a lot of rifes: Pennsyvlania & Virginia and going south from there they spread to the Carolinas. Privately owned rifles were more common post-Revolution.
I'm well aware of this; I am stating the fact of easily the most widely-believed misconception of the war, not implying or claiming say, that the 13 colonies were indeed crack shots but it wasn't up to them alone; they weren't at all.
Misconceptions are often wrong at their core. Take any war; the Great War, or World War One - How easily is it to find a post anywhere online about that war and find a top reply or comment doing something along the lines of talking about how "Napoleonic tactics" were used in 1914 and how magical it is that it all changed by 1918. Or blaming some infantry lieutenant for their perceptibly "stupid tactics" as if, even if they were stupid, that a little officer was the one who decided fundamental infantry doctrine?
Could just be interpreting this wrong but 2 is quite a few. I will presume we are all just contributing to solidifying the main
point here; it isn't like most (or anyone really) was shooting
Minié rifles in America, and in
general, despite what people would want to believe about the Old West, or of the 19th century, of the US through history in general, it was
not a gun-slinging nation.
I think the vastly made more important, on the individual level, focus on the
2nd Amendment is a whole other conversation, made much greater of a deal today than just about ever, but yeah - not a nation of sharpshooters, or shooters in general. (I mention it because the modern state of the US around gun culture, and living memory probably contributes greatly to the whole misconception, it would make sense.)
There are things like men's recreational shooting clubs set up by German immigrants
@gary alludes to, and I know I have seen threads at least mention before, more common around the 1850s onwards but that is nothing like the institutionalized
Corps of the British Army
dedicated to training rifle marksmanship to an army that is 220,000 strong in regulars in 1861; nor is it like having a
nationalized rifle-shooting association, nor a culture already familiar with rifles like the Norwegian, Swiss or Germanic states all benefit from that affects their own focuses on marksmanship (though none quite like the British Army in these waning years of Minié rifle supremacy).
Oh, and:
Yes, rifles had been issued before, but how many who had used them in the Mexican Wars were still around?
Obviously rhetorical, and
there is the fact that their rifle knowledge would be useless anyway - but giving it a thought - with the scales the US and Confederate Armies work with to begin with in the war, it would be a complete disservice to say they dwarf Mexican war numbers. Without any disrespect to the men of that conflict - if every Mexican war veteran (who shouldered something with rifled grooves) stepped up, it still wouldn't be enough.
What the US needed was at very least was a few years of a particularly popular earlier NRA, and more importantly institutional training of any kind. Austrians spent a lot less time than British on
distance position, aim drill etc. training; their soldiers didn't learn to judge distance - which perhaps makes the 1859 British manuals a little prophetic; they were officially adopted in March 1859, just a month before the 2nd Italian War of Independence, & my Field Exercise printed in June, the very month of Solferino.
Both manuals complement each other in many ways, and among the main themes it repeats, as I showed in an earlier post, i.e. 1st page for training, page 10 of the
Musketry Instruction - distance judging drill is claimed as the singular most important skill of the soldier. Keeping in mind the Austrian infantrymen are all taught to fire at known distances; just not judge distance themselves. Their officers' main role is to do it for them. Austrians are still, with this, lightyears beyond US practice are considered woefully inept in practice. (This doesn't come down to how difficult rifle training is, but just as comparison. The lack of judging drill for the individual made a huge difference.)
Was distance judgment institutionalized among all infantrymen in any sort of way, how to simply aim properly at different elevations? No. Nevermind the fact that guns of the Civil War may range from a Springfield M1861 with a maximum of 500-yard sights to an Enfield P56 short rifle with the 1100-yard sight, a Spencer's 800-yard sight or hell, a Maynard carbine and whatever its rear sight is graduated for (think about 200 yards at most generous); Nevermind how a unit might be issued various weapons that defeat having knowledge of exactly how to aim and hit necessarily with one of them; a Lorenz M1854 and Springfield M1861 do not shoot the same.
There is plenty to point out. You don't just "learn to shoot" with these. As
@Old Soldier put, marksmen take time. They also need the resources; what they got was the old fashioned "Leave it to your officers" that is recognizable to any older armies.
Let's make it clear. There were NOT regular - full-time professional - soldiers. Many instructors will have come from the State Militias - still using smoothbore muskets. They were teaching the DRILLS, to ensure the recruits could match their fire with regular soldiers - but they were not teaching them how to shoot. The percussion musket could fire three rounds, perhaps four, a minute and had an effective range of no more than 150 yards. The new Minie rifles had the same rate of fire, but an effective range of 400 yards, 600 in trained hands, and up to 1,000 for unit area fire, but these guys were not being trained how to make use of that technical advance. It takes time to produce a marksman (or even a decent shot) and they were not given that time. The generals wanted troops in the field, ready to go, so the instructors made it so. What they didn't get was marksmen.
The generals too, did not appreciate what a trained rifleman could do, should do, and deployed their troops as they always used to - as musket armed infantry. They expected nothing more. Even the trained Sharpshooter battalions, with accurate Sharps rifles, were deployed as line infantry! The concept of unit (company) fire and the 'beaten zone' at long range seems to have been totally ignored - and left to artillery.
A company firing at a battery in the field at 600-1000 yards was perfectly feasible and would have effectively caused the battery to cease fire and move away. Was that ever done?
The generals too, did not appreciate what a trained rifleman could do, should do, and deployed their troops as they always used to - as musket armed infantry. They expected nothing more.
This statement actually brings up quite an interesting thought; it is almost as though they did think the way so many others think about this. As before stated, the US Army's dress and fatigue uniform are collectively based upon French and Austrian influence; namely inspired by their light infantry;
Chasseurs and
Jägers. This is even more apparent at the time Hardee's was initially adopted, itself named Rifle & Light Infantry tactics for a reason. Copied from the 1846 French drill as we all know, for light infantry and the Tige system. The hunter's horn for light infantry now denotes all infantrymen, who all ideally carry rifle-muskets. Point being; the US Army models its uniform and official manuals off of light infantry dress; they follow the trend of copying the main basic idea in the 1850s of the change brought by the rifle-musket - the universal infantryman. The ideal US infantryman would have been perfectly flexible between skirmish and line formation, even if Hardee's is barebones compared to say, the 400~ total pages, possibly more (I'd have to count_ for the British manuals.
They go out of their way to ensure acceptably modern arms, especially that of the Enfield, Lorenz etc. are armed in number; the US Government has 1,200,000 Springfield M1861 and derivatives ordered, goes as far as purchasing 106,667 total Spencer rifles and carbines from 1862-63, delivered until 1866; while that is bit out there for the topic - nobody is doing that; the US is going out of their way to both get acceptably modern weapons and perceptibly advanced arms to equip their armies - the point, they armies feel that simply equipping themselves with rifle-muskets and the general best the day has to offer will make them... better, perhaps. Maybe, they think... they will "learn to shoot" practically in the field? Flawed idea but it seems to be what they are doing.
Italy for comparison; perhaps a poor example for being much shorter, but in the era surrounding the Expedition of the Thousand, 1860, it appears that the Garibaldi's forces - mass volunteer army - goes out of its way to predominantly use percussion smoothbores in that war. Not simply out of availability. They order for single-shot cavalry pistol-carbines to be made, some of their last real major use, and virtually as soon as the war ends and the Kingdom of Italy, for the most part, secured the new Army sets about getting itself proper uniforms and instantly in year 1 sets about getting a brand-new Fucello Model 1860/61 rifle-musket for the army, makes purchases from the likes of Lefaucheux, etc. all within a year of unification. Certain Italian political movements are known for their shirtsleeve uniforms - sure, but putting all of this into perspective it seems to all make sense, right? The Army that fought in 1860 seems to be led by men who consciously knew that between untrained mass volunteer armies, smoothbore percussion muskets were still relevant, and made little to no effort in procuring Minié rifles, got itself a good bunch of percussion smoothbores knowing it had no time nor point in attempting to train with the little time they gave themselves. Everything changes mere months after achieving their goals.
The US train of thought during the Civil War is, we need rifle-muskets. With time they start at least procuring quantities of things that nobody else has really done before. They are obsessed with quality and modernization yet simultaneously don't seem to want to - don't actively really have the means at all - to do it. It would be a different story if they really "wanted" troops of the smoothbore era, there was effort made to procure advanced arms. The basis being that, seemingly, "If we have advanced guns, our troops with eventually learn to shoot, and maybe our oldschool volleys will be deadlier and we will be more successful than the enemy."
