Patrick K. O’Donnell discusses one of the Luftwaffe‘s most deadly attacks and why most people have never heard of it:
Americans remember December 7 as Pearl Harbor Day, but most Americans have never even heard of the “Little Pearl Harbor,” which occurred in Bari Harbor, Italy, on December 2, 1943. More than 100 Luftwaffe bombers mounted a surprise attack on Allied ships moored in the harbor. Their bombs sank or rendered inoperable 28 of these ships. Nearly a thousand Allied troops were killed or wounded. along with hundreds of civilians.
Unbeknownst to those in the port, one of the ships carried liquid death in its belly. The American freighter John Harvey was secretly carrying mustard agent, in violation of international agreements that banned its use. President Franklin Roosevelt had covertly ordered the shipment of 100 tons of mustard agent to Italy for retaliation in the event that the Germans used chemical warfare against the Allied troops. The incident was covered up and remained a secret for decades.
When the German bombs hit the John Harvey, the ship’s hold immediately exploded with devastating violence, killing all those who knew about the mustard [gas]. Deadly liquid and gas flew high into the air and then slowly settled back down into the harbor, coating everything and everyone in the vicinity. Casualties would mount over the coming days and weeks as the agent slowly and painfully claimed the lives of many who had survived the initial attack.
Mustard gas was one of the nastiest relics of the attempts to break the trench lines during the First World War. Wikipedia says:
The sulfur mustards, or sulphur mustards, commonly known as mustard gas, are a class of related cytotoxic and vesicant chemical warfare agents with the ability to form large blisters on the exposed skin and in the lungs. Pure sulfur mustards are colorless, viscous liquids at room temperature. When used in impure form, such as warfare agents, they are usually yellow-brown in color and have an odor resembling mustard plants, garlic, or horseradish, hence the name. Mustard gas was originally assigned the name LOST, after the scientists Wilhelm Lommel and Wilhelm Steinkopf, who developed a method for the large-scale production of mustard gas for the Imperial German Army in 1916.
Mustard agents are regulated under the 1993 Chemical Weapons Convention (CWC). Three classes of chemicals are monitored under this Convention, with sulfur and nitrogen mustard grouped in Schedule 1, as substances with no use other than in chemical warfare. Mustard agents could be deployed on the battlefield by means of artillery shells, aerial bombs, rockets, or by spraying from warplanes.
