Certain military details are kept secret to prevent them from falling into enemy hands. However, during World War II, Congressman Andrew May appeared to disregard this practice. In a poorly judged press conference, he disclosed classified information, resulting in the loss of 10 submarines and the tragic deaths of 800 US Navy personnel.

The United States Navy was known for its successes following the country’s entrance into WWII. Despite Japanese attempts to sink their vessels, the Allied forces managed to evade their attacks. This was because, at the time, the Balao-class of submarine could dive to depths of 400 feet, deeper than the Japanese set their depth charges.

In 1943, Andrew May, the chairman of the House Military Affairs Committee, undertook a tour of American military operations in the Pacific Theater, where he obtained a substantial amount of classified wartime information. When he returned in June, he held a press conference and revealed that the high survival rates of American submarines were attributed to Japanese depth charges exploding at excessively shallow depths.

This revelation swiftly circulated through news channels and appeared in newspapers across the country.

Soon after the news spread, the Japanese naval anti-submarine units adjusted their depth charges to explode at greater depths. As a result, Vice Admiral Charles A. Lockwood, who managed the US submarine fleet in the Pacific, estimated that the breach in May resulted in the loss of 10 submarines and around 800 crew members’ lives.

“I hear Congressman May said the Jap depth charges are not set deep enough,” he said. “He would be pleased to know that the Japs set them deeper now.”

Following the press conference, the Navy’s Pacific Submarine Fleet released a report indicating that Japanese anti-submarine warfare (ASW) forces had failed to ascertain the maximum depth achievable by the US submarine fleet. However, the report did not specify whether the Japanese had adjusted their depth charge attacks to target deeper depths based on the information disclosed in May.

The ill-fated press conference was merely one of several challenges in Andrew May’s career. Early in the war, he partnered with two New York businessmen, Henry and Murray Garsson. Despite lacking any background or expertise in arms manufacturing, they sought to profit from the U.S. involvement in the conflict by securing government munitions contracts.

May, using his position as chairman of the House Military Affairs Committee, approached Army ordnance and other government officials on their behalf to secure war contracts, favors, and draft deferments. In return for his efforts, he received large cash payments, which were later exposed by a Senate investigative committee after the war.

This quickly escalated into a scandal, which intensified after testimony about the Garssons’ company’s profiteering and the flaws in their munitions. Investigations revealed that their 4.2-inch mortar shells had faulty fuzes, causing them to detonate prematurely. This is thought to have caused the deaths of 38 American servicemen.

The repercussions of Andrew May’s wartime mistakes extended to his loss in the 1946 election. He was also tried and convicted on federal bribery charges on July 3, 1947, after less than two hours of jury deliberations.

Despite attempts to avoid imprisonment, he was ultimately sentenced to nine months in a federal facility. Murray and Henry Garsson also received prison sentences.

Despite his tarnished reputation, May retained influence within the Democratic Party, which enabled him to secure a full pardon from US President Harry Truman in 1952. However, he was unable to fully revive his political career and, ultimately, returned to Kentucky to practice law until his death.
