Oh! I see I misspelled the word. I had it as Vulnus Sclopetican. It is Vulnus Sclopeticum. That Private Joseph Dedman died of Vulnus Sclopeticum on April 16,1865 in Selma,Alabama after checking into the hospital on April 3, 1865. It must have been as a result of the Battle of Selma where the battery was overrun.
I found the term mentioned here:
