Eighth
U-66's eighth patrol started after a quick refit on 7 April 1943 when she left Lorient. At 148 days, it was to be her longest. She first sank the 10,173-ton American Esso Gettysburg, which was carrying crude oil, on 10 June after unsuccessfully attempting to attack several other American tankers. On 2 July, she successfully sank the 10,195-ton Bloody Marsh (this ship was on her maiden voyage), with a torpedo. The last ship encountered on the patrol was the 10,172-ton Cherry Valley, also American, which she sank on 22 July. U-66 then returned to Lorient.

Bloody Marsh was a T2-SE-A1 oil tanker built in 1943 in Chester, Pennsylvania, by Sun Shipbuilding and Dry Dock Company. It was on its maiden voyage from Houston to New York with a cargo of 106,496 barrels (4,472,832 gallons) of oil. While steaming off the coast of South Carolina on July 2, 1943, a torpedo from German submarine U-66 struck the aft port side, destroying the engine room and killing three of the crew. The rest of the crew and armed guards on the ship boarded life rafts and escaped. A second torpedo struck the port side amidships and broke the tanker in two, sinking it quickly. U-66 surfaced to view the sinking ship and struck one of the lifeboats, knocking the sailors into the sea before leaving the scene.

As one of 87 shipwrecks listed on NOAA’s Potentially Polluting Wrecks list, it was important to find Bloody Marsh and get an ROV on site to identify the wreck and assess it for pollution risk. About a month after the ROV dive in 2019, a colleague at the Bureau of Ocean Energy Management, Jack Irion, passed on some information from a study of surface oil slicks found through satellite imagery. The researchers found a repeating slick in the area of Bloody Marsh off South Carolina. I submitted a new survey area to NOAA Ocean Exploration based on this information, and while surveying in the area this past summer, they found a shipwreck-like target in the multibeam data 4 kilometers (2.5 miles) downstream of where the oil slicks originated at the surface.
