Loose lips sink ships, the old saying goes. Nothing could be more true. And the combination of an international audience with highly classified intelligence along with a complete lack of understanding for what's important and what's not can be disastrous. It should come to no surprise for anyone reading that a Congressman learned this the hard way.
Back then, at least, it was enough to cost him the next election.
This f*cking guy.
In the early days of World War II, the Japanese didn't really understand Allied submarine technology. Most importantly, they had no idea American and British submarines could dive so deep. When fighting Allied subs, the Japanese set their depth charge fuses to explode at a depth roughly equivalent to what their submarines could handle, which was a lot more shallow than American and British subs could dive. As a result, the survival rate of Allied submarines encountering Japanese ships was amazingly high.
For the first year or so of the war, the Americans enjoyed this advantage in the Pacific. Japanese anti-submarine warfare was never sophisticated enough to realize its fatal flaws, and American sailors' lives were saved as a result. Then Kentucky Congressman Andrew J. May made a visit to the Pacific Theater and changed all that.
Droppin' charges, droppin' bodies
The Balao-class submarines of the time could dive to depths of some 400 feet, much deeper than the depth Japanese ships set their depth charges to explode. Congressman May was informed of this during his visit, along with a ton of other sensitive war-related information. Upon returning from his junket in the war zone, May held a press conference where he revealed this fact to the world, informing the press wires that American sailors were surviving in incredible numbers because the charges were set too shallow. The press reported his quotes, and eventually, it got back to the Japanese.
Who promptly changed their depth charge fuses.
A depth charge-damaged submarine.
Vice-Admiral Charles Lockwood was understandably livid when he heard the news, not just because a Congressman had leaked sensitive information to the press for seemingly no reason, but because he knew what the tactical outcome of the reveal would be. And Admiral Lockwood was right. When the Japanese changed their fuses, it began to take its toll on American submarines, which might have normally survived such an attack. He estimated the slip cost ten submarines and 800 crewmen killed in action.
"I hear Congressman May said the Jap depth charges are not set deep enough," Lockwood reportedly told the press. "He would be pleased to know that the Japs set them deeper now."
When the time came for May's re-election campaign after the war in 1946, the reveal (which became known as The May Incident) along with corruption allegations became too much for the Kentucky voters, and May lost his seat in the House of Representatives. May served nine months in a federal prison for corruption.
