At the beginning of the Civil War, the US Army, while well trained and equipped, was small and in no position to fight a major war of any kind. Many regiments had not been brought together in years with companies spread around the various states and territories guarding national borders, fighting Indian and civil uprisings and generally keeping order. It was going to be a war fought by state troops - on both sides. Initially, the states were responsible for arming, training and equipping their own troops. This led, of course, to many, many problems and a study of the first year of the War (before mid to late 1862) show that both sides suffered through growing pains. Early on, many states were sitting on out of date weapons provided to them by the Federal Government under the Militia Act of 1808. Flintlock muskets predominated in the hands of many troops on both sides. Both sides used flint muskets through the early period.
Included in some of the inventories of the various states were, indeed, flintlock English muskets. A little background: The US Arsenal at Harpers Ferry had “English muskets” listed in inventory (some may have been captured/surrendered arms from the Revolution but the majority were India Pattern flint muskets purchased by the US from Britain in the 1790s) until at least the War of 1812 and it was the preferred weapon of the US Marine Corps until about that time. Some were also sent out to the various states for issue to their forces. At the beginning of the Civil War, many flint muskets were issued to state troops, among them those from England ”“ the Brown Bess as we know it now. For proof of the issue of flint muskets to state troops, read “Message from the Execttive of the Commonwealth, with Accompanying Documents, Showing the Military and Naval Preparations for the Defence of the State of Virginia, &c. &c.” at this link:

Fascinating stuff! It will take a while but it is worth it. Remember that the Commonwealth of Virginia was the wealthiest state in the Union and had what was considered the best military organization in 1861 ”“ at least on paper. As you read down through what was issued to the various organizations coming into active service as of June 17, 1861, you will see listings like:
(1) Altered Percussion Muskets
(2) Altered Muskets
(3) Rifle Muskets (a RARE one!)
(4) United States Flint Muskets (common)
(5) Flint Muskets (common, not saying what kind)
(6) Virginia Flint Muskets (common, made by the Virginia Manufactory of Arms, Richmond)
(7) Altered Virginia Rifles (longrifles made as the muskets above or by State Contractors for Virginia)
(8) Virginia Rifles (as above, unaltered)
(9) Double Barrel Guns (cavalry? Maybe?)
And, finally,
(10) English Flint Muskets
Virginia, in at least two instances for a total of 700 muskets, issued English flintlock muskets to its troops. Most seem to have gone to troops recruiting in the Western part of the state where the population was thin and, in some cases, not loyal to the Commonwealth.
Now, does this mean that the “Brown Bess” was later percussioned and re-issued to Confederate troops? Not necessarily, but it is possible, at least one likely Confederate percussion conversion of India Pattern Bess have sold recently at auction:

While not in perfect condition, it does appear to be a legitimate military conversion using a Confederate hammer. But was it common to see a percussion Bess in anyone’s hands on either side? No, it was not. At best, both the Union and Confederate Ordnance people would have considered it an arm of the “4th Class”, caliber too large, and replacement parts unavailable for repair, etc. If indeed Confederate, it likely saw use by reserve troops called out in an emergency or by guards at various prisons, government facilities like factories or mines in out of the way places where Union troops would not be likely to show up but armed men were necessary to keep order. As far as use by combat troops, remember, the Union forces by mid ”“ 1862 had contract arms coming at an ever increasing rate and even the Confederate forces were much better armed than post-war apologists claimed, by that time they had ever increasing numbers of the P53 Enfield (many from the London Armory and made to British Government standards of finish and interchangeability) as well as excellent arms from Austria along with a sizable number of captured weapons gleaned from battlefields. Odd ball, substandard muskets were rare by late 1862, even the standard .69 smoothbore muskets were few and far between by the end of the War.
Sorry to ramble and I hope some of this helps to answer the question.
