Your memories have slightly shifted: the house at the center of the Manassas (Bull Run) battle belonged to Mr. Wilmer McLean and his family. After the fright of that battle, Mr. McLean moved to Appomattox and his home there became the site of Lee’s surrender to Grant.
Didn’t remember the name, but I remember the spindle table where the surrender took place. I found one in Sackets Harbor at an antique barn. Sold it years ago, and I know it isn’t the one from the Mc Lean house, Libby Custer had that one. Too many names to remember after 81 yrs. Yes Grant was stationed at Sackets Harbor early in his career. Its a known fact up there. 2 lawyers from NYC bought the whole fort for about 200k and tuned the place into condo. It had a parade field and Enlisted barracks still there. Oh and the Victorian Homes. A really nice place at the junction of Lake Ontario and the St Lawrence. Geeez I miss being up there, but not in the winter.
What are the odds of that happening?
