Roman Soldiers Likely Hit by Chemical Weapon Archaeologists discover secrets in ancient bones By Kevin Spak, Newser Staff Posted Mar 13, 2011 10:52 AM CDT 7 comments Comments New evidence finds that some Roman soldiers dug up in the 1930s may have been the first victims of chemical weapons.

But now, researchers believe they were actually some of the earliest victims of chemical weapons—and the first whose remains have ever been found, LiveScience reports. Archaeologist Simon James realized the tunnels were too small for a fight, so he hit on the theory that the Persians heard the Romans digging a counter-tunnel toward them, set a fire as a trap, and threw in sulfur and bitumen to form a poison gas. “It would have almost been literally the fumes of hell coming out,” James says. He admits it's a "circumstantial case," but it's a compelling one. “I think [James] really figured out what happened,” says another historian.
