General Buford’s calvarymen on Cemetery ridge on the first day of the battle were armed with Spencer breech loaders, it would be interesting to see if there were fewer of those found loaded then Springfield and Enfield muskets used by the Union and Confederate infantrymen, respectively. If so, it could be a function of the complicated procedure needed to load a musket in the heat of battle. Probably a lot of factors. “The Killer Angels” movie, later renamed “Gettysburg” is a great movie. The Killer Angels book was very good as well. Walking that battlefield was a very memorable experience, especially for a civil war history buff like myself.
