At 07.06 hours on 11 Jul, 1940, the Janna (Master Thorbjørn Bøttger), a straggler from convoy HX-54, was torpedoed and sunk by U-34. The ship had lost the convoy on 9 or 10 July in thick fog. One torpedo struck on the port side below the bridge, blew a part of the bridge away and caused the ship to sink vertically at about 08.00 hours. All crew members abandoned ship in three lifeboats. The boats were later circled by an aircraft, but it was believed to have been German because they were not rescued until 18 July. The lifeboats landed five miles off the Mizen Head, Ireland after 60 hours. They had fired three or four rockets to attract attention, but they only had seen the Estonian steam merchant Kit, which went alongside on 12 July, but for some reason left the boats behind.
