I went to Mass in that chapel in 1971.
I was stationed at Ft. Jackson from May 1971 until September 1972. I don’t remember ever going to Mass at the chapel. I do remember walking to St. Joseph Church on Devine St. for 5:00 Mass and stopping by Burger King on the way back to the fort. That was back when I could walk a few miles without stopping to catch my breath every few hundred yards.
