				Enemy comes towards me at a sharp target angle.  Turned away and maneuvered ahead at highest speed.  Matched course and speed.  Steamer steers about west.  260-280°, 9-10 knots.  Set off a bit to starboard on the favorable sun side.  Steamer disappeared a long time in a rain squall.  By slowly falling back I soon have him in sight again.  Enemy always lies on a westerly course.

			As before.  Long S-Swell

				Got into shooting position on changing courses.  It turned out to be a medium-sized tanker with a stern cannon, about 10.2 cm and a machine cannon, mounted on a stern platform.  Bridge between two masts.
		21.47		Multiple shot from tubes 2 and 3.
				Depth 3 meters, estimated values.

		07.08.42		Enemy speed:  9 knots.
				Enemy target angle:  bow right, 85°.
				After 84 seconds torpedo running time, - 1230 meters running track 2 detonations follow one after another.  Both torpedoes hit at the aim points, and 2 normal explosive column are clearly recognized in the periscope.  1st hit forward edge, 2nd hit after edge of the bridge.  Steamer remains lying stopped and quickly takes a list to starboard.  2 boats were put to the water.  Despite this there are crew members on board.  5 men man the stern cannon.  List was equalized by counter flooding and the tanker floats on an even keel again.  After hit hole is very large and I hope that both hits are enough.  Despite this the tanker does not settle deeper.  I decided on a coup de grâce.  Turned for a stern approach.
		21.57		Shot from tube 5.
				Estimated and set values:
				Range - 1500 meters, speed - 0 knots.
				Target angle - bow right 90°.
				Miss, because suddenly in the listening gear propeller RPM were determined.  Tanker propellers again make 50 RPM.  Ran at GF alongside the tanker.  Then the PRM cut out again, started and then stopped for good.  Now ran in for a 2nd coup de grâce.
		22.48		Shot from tube 1:
				Range - 800 meters, speed 0 knots.
				Target angle - bow right 90°.
				After 30 seconds running time = 450 meters running track hit amidships.  Tanker settled a bit deeper, takes a strong list to port.  However it still won't sink.  I decide to finish the job at the beginning of twilight with artillery.
		23.00		Surfaced and prepared artillery.
		23.30		Shot with all weapons at the lying stopped tanker on different courses alternately on distances of 800-600 meters.  Despite the long swell aiming was good and good hit results were realized.  Of 67 shots 10.5 cm shells 55 were hits.  3.7 cm, 2 cm and M.G. 34 shot the bridge superstructure as well as the stern and bow effectively.

		20.00	ER 3611	Surfaced.  Artillery ready!
				In 3 approaches the tanker was shot with all weapons.  Heating oil began to burn and soon the ship is in bright flames.  The oil pours burning onto the sea.  Tanker settles deeper quickly.  Ran off to the lifeboats, to take the Captain and Chief Engineer on board.  In so doing it was determined that it was the British tanker "VIMEIRA" 5728 GRT.  Loaded with heating oil from Aruba for Freetown.  Because the Chief Engineer was killed in the torpedo explosion, only the Captain of the ship was taken on board.  Thereafter moved off on old course, 21°.  The tanker was still in bright flames.  The over deck is now completely overspilled.
		22.30		"VIMEIRA" sank.
				Still only the dark smoke clouds show along the evening sky.  According to statement of the Captain, by the hit the ammunition for the two stern cannons went high order.  Therefore the disastrous effect.  The engine watch and all people aft were killed.

			From exact records and a review of all courses of steamer sighted or sunk during the past few weeks in area ES and ET, it could be seen that very few of these ships had direct course to or from Freetown.  Namely of 15 ships only 4.  The other 11 ships steered 130-140° or 290-300°.  From this I deduced that this traffic was primarily Great Circle traffic from North American harbors to ports on the west coast of Africa or Cape Town, rather than Freetown traffic.  So I did not go on a direct course to Freetown, but continued to search southeast in legs to pick up the Great Circle traffic again, which was probably only stopped temporarily, the ET 70 and 80 area seemed especially promising to me. But nothing was seen!

				The view of B.d.U. that return transit was not necessary yet is not understandable to me.  I based my decision on return transit on the following calculations:  Total 3600 nm.  Day's run only 150 nm, because one must steam against the NE Trade Winds.  So 24 days.  2.8 cbm per day with 3 cbm fuel consumption.
				24 x 2.8 = 67.2 cbm
				For that  = 5.0 cbm for GF.
				= 72 cbm    When charging while going through Bay of Biscay and vicinity of the coast.  Nevertheless, Radio Message has caused great joy. I now know we can stay in the operations area and the torpedoes can still be fired.

				Steamer stopped immediately and turned athwart the swell.  Settled deeper astern very quickly, so that the aftership is already overspilled in the shortest time.  Boats were launched.  Steamer first transmitted after 10 minutes, however only with emergency transmitter, was not heard by a land station.  It was the refrigerator ship "TUSCAN STAR" 11,449 GRT, British nationality.  Steamer took a strong list to starboard and settled steadily deeper.  When the aftership was already overspilled up to the smokestack, 2 lifeboats still lay alongside.  When these boat finally cast off, the bow rose into the air, stayed for a short time vertically up and down, then sank quickly over the stern post.

				Ironically, now, where every drop of fuel is needed for the transit to the meeting point, I still have such a steamer on the way. But with 8 cbm, there is still plenty to start with.  In any case, first closed at maximum speed and matched heading and speed.  Fortunately, it is not a fast runner.  Steamer steers 200-180°.  Speed about 8-10 knots.  Am soon in a good, favorable position and can already dive to attack at 12.09 hours.

				Set values:
				Enemy target angle:  bow left 90°.
				Enemy speed - 10 knots.  Torpedo depth - 3 meters.

				After 26 seconds torpedo running time = 390 meters shooting range there follows first and a few seconds later 2nd and 3rd hits, amidships, before and after edge of the bridge.  Very loud detonations.  The chap has enough!  Takes a strong list to port and settles deeper quickly.  Despite this a few fellows ran to the aft cannon, but soon have to realize that there is nothing left to do and go quickly into the boats.
				The steamer settles deeper very quickly, the list to port is stronger and stronger until the steamer suddenly capsized over the port bow and sank over the forestem.  Surfaced and went to the lifeboats.  Took the Captain of the ship with papers on board.  Thereupon came to old course.  It was the British steamer "PETERTON", from Hull to Buenos Aires with coal.
				5221 GRT.
				Steamer was armed with 1 stern cannon about 10.5 cm, 2 Oerlikon 4.7 cm quick loading cannons and 4 throwing mechanisms for light depth charges.
				There was tremendous rejoicing in the boat when the torpedoes hit. This steamer appeared shortly before the limit of Route Anton and shortly before the lat minute with our fuel, as if sent by "Fortuna" just front of the torpedo tubes and yet still some torpedoes found their well-deserved sacrifice.

	Comments of the Befehlshabers der Unterseeboote
	on the Kriegstagebuch of "U-109" from 4.6. - 6.10.1942.
	A well and deliberately executed patrol.  The tenacious hunt for fast independent ships brought the commander as a success two large, valuable ships.
	With the large number of boats it is not possible to supply all with fuel.  Ddistribution takes place by Leadership based on situation and operation area.  Therefore a disregard of ones own boat is not to be taken personally and cause discord, as is evident from this K.T.B.
		For the Befehlshabers der Unterseeboote
