Gas rewired the battlefield: a slow-acting weapon that demanded discipline, science, and new tactics.
Some gas masks used against chlorine were improvised from damp towels and car exhaust tubes, not official equipment.
The deadliest gas attack in WWI killed more soldiers from asphyxiation and panic in trench systems than from direct chemical burns.
Navy shells containing gas inadvertently leaked onto allied troops’ rations, causing sickness long after the battle ended.
German gas strategies relied on weather, but sudden wind shifts sometimes carried deadly fumes back toward the gunners themselves.
