Before you go to calling re-enactors stupid or something, keep in mind that in most cases any hand to hand fighting was choreographed. No one wanted to hurt or get hurt even if it wasn't rehearsed. Considering the thousands upon thousands of re-enactors who have been in the hobby since the 1960's, there have been remarkably few injuries. Most injuries have been due to overweight and older soldiers who went down with heat strokes or heart attacks. I don't have any statistics at hand (and there probably hasn't been any worked up anyway), but from 20 years in the field from 1974 to 1994 at the peak of the hobby I never saw anyone killed and very few injured and most of those, besides the above mentioned heat and heart problems, were guys who got cut or banged up by their own weapons or singed by a cooked off load when shooting a hot dirty musket. Many mishaps occurred in camp. As for fired ramrods, those were few and far between. As in the real battles, during the excitement of battle when the firing was fast, occasionally someone would forget to remove a ramrod and fire it. I know of a few cases where guys were struck in the arm or had one land near them. It was rare, but it only took one or two cases to have a rule that though ramrods could be kept in the muskets, we couldn't draw them in the field except for during inspection prior to battle. Later the NPS ruled that they had to be left in camp and most other events followed suit.
And like I said before, we aimed at the enemy. We knew we were shooting blanks and so did they. To duck hunt when firing at an enemy line takes any sense of realism from it. And when at close range we either aimed just over the line or we didn't fire at all and just charged. That depended on the scenario or our commanders.
The only major injuries were loss of hand and arms when a load in a field piece would cook off when being rammed. This was pretty rare but did unfortunately happen. And a few cavalrymen broke some legs, arms and backs getting knocked off a horse. I do know of one infantryman in our unit who lost part of a hand due to an original Austrian rifle blowing up, but that didn't happen at an event.
I spent 10 years of my hobby as a sharpshooter. Many times I tracked officers with a scoped Whitworth and fired at them. I told one once that I had him in my scope for quite awhile at about 500 yds. and when he saw what I was armed with he said that he was awful glad we were just playing. But other than that he was fine with it. I've looked down the barrels of many muskets aimed directly at me and it never bothered me. My only concern was if it was at very close range. This only happened in very dense woods and as soon as we saw that we were too close, we held fire or elevated our pieces. We trusted our fellow re-enactors. Maybe they can't now.
I've been in scores of battles ranging from squad sized events all the way to the 125th Annv. of Gettysburg with 15,000 troops and I felt safer doing what we were doing than if I was in a sandlot football game. The only time I ever got scared was marching over the top of South Mountain in a column of fours in a severe thunderstorm. We were one giant lightning rod until we were able to scatter and ground our arms. Considering the numbers of largely untrained men with guns turned loose for a weekend, I'd say that re-enacting ranks quite favorably with any other outdoor sport or hobby in the world as far as safety is concerned. I'm sure that there are a few malicious individuals out there in the ranks and of course those who can't or won't learn how to do this safely. But it's up to their comrades and commanders to either discipline or get rid of them.
And by the way, after I posted the above, I went back and re-read an earlier post of yours. Seems that I'm a moron who needs to be culled from the herd. Thankfully, somehow I've survived all these years. And you live far enough away to be safe from getting your ears boxed. The above information was for you, but I'm redirecting it to the others to read since you wouldn't want to read something a moron wrote. Just remember not to poop in someone else's sand box.
Claude, I'm sorry if I went over the line a little and got off topic. I couldn't let such remarks go unanswered.
