Roman soldiers at Dura Europos in Syria were killed by chemical warfare when Persian forces set sulfur and bitumen ablaze inside tunnels, turning the air to poison. Nineteen bodies were found stacked 3-4 high blocking the tunnel entrance. French archaeologists discovered them in the 1930s but assumed they died in combat. It took until 2009 for archaeologist Simon James to confirm these men as the earliest documented chemical warfare casualties in history. The site remained untouched for 1,700 years.
