the ship began her final voyage. Waalen was found guilty and sentenced to 12 years in prison for espionage and a concurrent 2-year term for violation of the Foreign Agents Registration Act. U-69 also sank Tewkesbury about south of the Cape Verde Islands on the same date (21 May). Her master was awarded the OBE for his actions, but never knew about it; he was lost when Newbury went to the bottom on 15 September. She then sank Sangara in Accra harbour on 31 May 1941. The ship went down in of water, her bow was still visible. (The vessel was salvaged in 1943 and her cargo sold, she was broken up in 1947). Robert Hughes was lost to a mine laid by U-69 on 4 June. The submarine sank River Lugar southeast of the Azores on 27 June 1941 and Empire Ability on that same day. On the return journey, U-69 was engaged in what was an ultimately successful gun-duel with Robert L. Holt southwest of the Canary Islands on 3 July 1941. She fired 102 high explosive and 34 incendiary rounds from her deck gun, 220 rounds from her 20mm anti-aircraft weapon and 400 rounds from her MG 34 machine gun at the merchantman. The boat returned to France, to St. Nazaire on 8 July. Unfortunately for the crew of U-69, it was nearly a year before they sank another ship, due to the tightening of convoys in the second half of 1941 and some frustratingly short patrols, called off because of mechanical failure or sickness on the boat. Fourth and fifth patrols Patrol number four was relatively short, lasting barely a week and hardly leaving the Bay of Biscay. U-69s fifth patrol took her northwest of St. Nazaire towards Greenland; although longer, it was also unsuccessful. Sixth and seventh patrols The boat's sixth patrol was uneventful. During her seventh outing, she was depth charged for several hours by escorts of a convoy on 21 March, west of Ireland. She escaped without any damage. Eighth patrol U-69 added to her tally when she sank the tiny four-masted sailing vessel James E. Newson off the United States' seaboard with her guns. She sank a further three ships that month, making use of the "Second Happy Time" to add to her score. On one of them, Lise, the first mate, the Norwegian Hangar Lyngås, survived a total of four torpedoings.
