The SS City of Rayville was the first American vessel sunk during World War II, and was sunk by a German mine just off Cape Otway, Australia. This field of approximately 100 mines had already claimed the British steamer SS Cambridge, less than 24 hours previously off Wilsons Promontory.
On 8 November 1940, City of Rayville sailed into the Bass Strait and at 7:47 pm, she hit a mine. The explosion was powerful enough to rip out the foremast, as shrapnel (including ingots of lead, the vessel's cargo being 1,500 tons—37,520 bars—of Port Pirie lead) rained down on the ship's decks. The 38 crew members were able to safely abandon the vessel in lifeboats, although one mariner (James Bryan of Norfolk, Virginia) re-entered the vessel to find his personal items and subsequently drowned. The vessel sank, bow first, in 35 minutes. 
The lightkeeper stationed at Cape Otway Lightstation witnessed the sinking, and three boats from Apollo Bay went in search of survivors. The ship's lifeboats were found, and successfully towed back to Apollo Bay, arriving at dawn, 9 November 1940.
This preceded the attack on Pearl Harbor, in December 1941, by more than a year, and resulted in the death of the first US seaman in World War II.
The site of the wreck is approximately 14 kilometers (7.6 nmi) south of Cape Otway, with the vessel at a depth of 70 meters (230 ft). The wreck's general location had been known since 2002, but it was finally pinpointed using advanced sonar equipment.
