The whole event was poorly done and a waste of time and money.
The 55th Massachusetts was stationed on James Island, and Folly Island, S.C. While doing research at Cornell, I came across a collection belonging to the Assistant Surgeon for the unit. It was a gold mine with maps, drawings, a diary, photos, etc., and a large part of it had to deal with the battles and skirmishes that the 55th was involved in on James Island. The Doctor had gone back to James Island years later, and communicated with members of the 55th, and also some of the Confederate soldiers who were involved in the battles. There were a ton of letters between them. I used to access the Charleston newspaper online back then, and found an article about a couple of people who were trying to get a battery, and the Confederate earthworks, called Fort Lamar preserved on James Island. I managed to get the name and phone number of one of the guys from the newspaper, and called him up. I sent him all the documents (tons of it), and within a month or two, they invited me to come visit so they could show me all the sites they had discovered, and were trying to get protected. One of the guys, and his wife put me up on that trip, and every other trip I took down there. It was extremely satisfying to be able to see the sites I had read about for years. Now in my 70's, I don't get around much, and haven't been to that area in probably 15 years. It's nice to see that the Trust has flourished, and gone on to get more sites preserved despite one of my friends having moved to Georgia.
The Trust preserves Revolutionary sites as well. I hadn't been to their website in a long time, and just did a search for it, and found that they have been busy getting several more sites preserved.
