30 of her British Army passengers were QAIMNS nursing sisters. The other 133 passengers were fare-paying civilians. 12 were children, the youngest being a one-year-old baby girl. Six were doctors, five of whom were South African. One passenger was Rudolph Dolmetsch (190642), classical musician and composer, then serving as Regimental Bandmaster with the Royal Artillery. Ceramic sailed with Convoy ON 149 until it dispersed as scheduled in the North Atlantic. She then continued unescorted as planned. As on her previous departure in January, she first headed west because of the threat of enemy attack. At midnight on 6–7 December, in cold weather and rough seas in mid-Atlantic, hit Ceramic with a single torpedo. These were followed two or three minutes later by two more that hit Ceramics engine room, stopping her engines and her electric lighting. The liner radioed a distress signal, which was received by the . The crippled liner stayed afloat and her complement abandoned ship in good order, launching about eight lifeboats all full of survivors. About three hours later U-515 fired two more torpedoes, which broke the ship's back and sank her immediately. By now it was very stormy and raining. The heavy sea capsized some of the lifeboats and left many people struggling in the water. Those boats that were not capsized stayed afloat only by constant baling. Next morning the BdU ordered U-515 to return to the position of the sinking to find out the ship's destination. About noon the U-boat commander, Kapitänleutnant Werner Henke, decided to rescue the Ceramic'''s skipper. In heavy seas, he sighted one of the lifeboats and its occupants waved to him. The storm was now almost Force 10 and almost swamping U-515s conning tower, so Henke ordered his crew to make do with the first survivor they could find. This turned out to be Sapper Eric Munday of the Royal Engineers, whom they rescued from the water and took prisoner aboard the submarine. No other occupants of the lifeboats survived. The storm was too severe for neutral rescue ships from São Miguel Island in the Azores to put to sea. On 9 December the Portuguese was sent to search for survivors, but found none. Munday was kept prisoner aboard U-515 for a month, including Christmas and New Year, until she completed her patrol. When she returned to Lorient, Brittany on 6 January 1943 he was landed at Lorient U-boat
