Herbert G. Claudius was in command of the patrol ship USS PC-566 in 1942. His mission and that of his crew was to monitor the Louisiana coast and its territorial waters for signs of any Nazi u-boat activity. On July 30, 1942, they got their chance, sinking a submarine that was preying on American shipping. For this, he was awarded the Legion of Merit with a Combat V device. The medal was issued in 2014, 72 years after the action.
At the time, Claudius was relieved of command for the same action.
USS PC-566 was a submarine chaser patrol boat, much like the one seen here.
In all, Hitler sent around 22 or more u-boats into the Gulf of Mexico at the outset of World War II, and they were successful. The submarines prowling the coasts of Texas and Florida picked off an estimated 50 ships during the war. They were wreaking absolute havoc on American shipping, and the United States Navy was only able to sink one of them. That's the u-boat taken down by Claudius' USS PC-566 and her crew.
On July 30, 1942, the passenger liner SS Robert E. Lee was torpedoed and sank by U-166 45 miles south of the Mississippi River Delta. Upon entering the area, Claudius and his crew spotted U-166's periscope and dropped depth charges into the water until an oil slick bubbled up to the surface – proof positive they hit their target, possibly destroying the boat.
The sunken wreckage was later found by archeologist Robert Ballard and his Nautilus crew – the same crew who found the Titanic in 1985.

When Claudius reported the action to the Navy, the Navy was skeptical because the crew of PC-566 had not yet received anti-submarine training and admonished the crew of the patrol boat for poorly executing the attack. Their skipper was relieved of his command and sent to anti-submarine school instead of receiving the Legion of Merit he so richly deserved. After reviewing the evidence presented to the Navy by Ballard and by oil companies who also found the wreck, the Navy reversed course, just 72 years too late.
In a 2014 ceremony, Claudius' son, also named Herbert G. Claudius, received his father's Legion of Merit from then-Secretary of the Navy Ray Mabus and Chief of Naval Operations Adm. Jonathan Greenert at the Pentagon. The elder Claudius, who died in 1981 after 33 years of Naval service, "would have felt vindicated."
