The Antietam on the Web database is now up to 22,000 individuals.
The entry getting us to that number is for the man under this impressive stone in Colchester, CT: Henry A Ransom, late Corporal, 8th Connecticut Infantry. He was seriously wounded in the knee at Antietam in September 1862 and troubled by it for the remaining 20 years of his life.
