			S 5, Sea 3-4, 9/10, Vis. 12 nm
		19.20	During the evening twilight shadow in sight bearing 205°T, range = 4000 meters by surprise out of a black rain squall.  Because the shadow is relatively well out, but the type can still not be distinguished and the boat cannot remain unnoticed with certainty, submerged with Crash dive to depth A +0 meters.
		19.45	AL 2767                                   Surfaced, because  by sound bearings the vessel has shifted astern.  Nothing seen after surfacing.  In the meantime it has grown quite dark.  Pursued in the direction of the last sound bearing.  At times the visibility is below 300 meters in rain squalls.
		20.23	AL 2792	Shadow is still not in sight, therefore dived to listen.  Sound bearing in 150°T.
		20.31	AL 2792                                   Surfaced and pursued in the direction of the last sound bearing.  Visibility has still not improved, nothing is seen.
		21.12	AL 2793	Dived again to listen.  Sound bearing in 130°T.
		21.24	AL 2793                                   Surfaced.  Pursued in the direction of the last sound bearing.  Visibility has grown better, rain showers have let up.
		21.41	AL 2871                                   Shadow in sight again bearing 113°T, range = 6000 meters.  Maneuvered ahead for attack.  In so doing the shadow is distinguished as a medium freighter.
		22.44	AL 2872	3-fan from tubes 1, 2 and 4.  Miss.  Target speed 10 knots, target angle = 80°, lead angle = 20°, depth 3 meters, torpedo speed 30 knots, estimated range = 2000 meters.  Miss unexplained because a 3-fan at 2000 meters would probably have overcome the inexactness in estimation.
			SSE 2-3. Sea 1-2, overcast, Vis. 1-4 nm, no marine phosphorescence, light Northern Lights
			Possibly shortly before or at the shot the enemy turned 30° in the context of his zigzags.  Maneuvered ahead for a new attack.
		22.55	2 detonations heard, probably detonation of the torpedoes at the end of the run.
		22.49	AL 2873	Incoming Radio Message 2111/10/724:  Borchers, Hessemann, Kremser, Heine, Soden, Kessler occupy patrol line at economical speed from AL 7411 to 7849.  Boats form Group "Habicht".
		23.54	AL 2881                                   Dived for submerged night attack.  The decision to attack submerged was taken to allow the boat to approach closer than with the precious shot in the now prevailing bright night.
		11.01.43	North Atlantic
		00.33	AL 2882	Submerged 2-fan from tubes 1 and 3, target speed = 12 knots, target angle = 60°, lead angle = 20°, depth = 2 meters, torpedo speed = 30 knots, estimated range = 800 meters.  After 42 seconds detonation.  Hit under the bridge.
			SSE 2-3, Sea 1-2, 9/10, no marine phosphorescence, Vis. 3 nm
		00.37	AL 2882                                  Surfaced.  Freighter lies stopped, had set out boats and sends emergency signal on the 600-meter wave with position.  Freighter estimated at 6000 GRT.
		00.59	AL 2882                                  Coup de grace from tube 5, because freighter was not noticeably sinking.  Hit about forward 40 meters after 65 seconds.  Freighter apparently floats on cargo, only settles a little deeper.
		01.45	Freighter lies on a even keel and has only settled a little.  2nd coup de grace from tube 2, hit about aft 20 meters after 65 seconds.  Shelling seemed inadvisable, since in spite of set out boats lights were still frequently seen on deck.

			Lat.:    59°38'N	"        Submerged:    20.4 nm

		12.45	AA 3861                                   Approached to about 2000 meters, when the enemy zigzagged away.  In the prevailing swell proceeding submerged is difficult so that the periscope is nearly always over spilled, as a result details could not be distinguished.  Only on the forecastle there was an extremely large companion ladder.  Painting on the vessel was the normal camouflage, however without the Danish flag on the side of the hull.
		13.10	Surfaced.  The motor ship is 10000 meters away.  Now closed to stop it in accordance with the Prize Regulations - the boat is outside of the blockade area - and possibly to sink with artillery.
		13.19	At range = 8000 meters it turns towards us, the ship previously lay at target angle 170°.  When turning a small cannon is recognized on the forecastle.  The large flag is taken away, in its place a small flag is set, that at the range cannot be distinguished.  Turned away, ran off at highest speed.  The motor ship now opens fire, apparently only with automatic weapons, because the muzzle flashes are very small and no smoke is seen.  The forward cannon was probably not used because on this course the enemy drives exactly into the sea.  Even if he had shot with the forward cannon at this range, with the poor aiming possibility, the boat was hardly endangered.  Naturally the automatic weapons could not reach so far.  Therefore with small zigzags and highest speed ran off on the surface.

			Sent no further contact keeper reports because there are 2 contact keepers at the convoy.  Convoy consists of up to now recognized 16 steamers in a broad formation.  Starboard abeam and starboard ahead 1 destroyer each, that are located  about 1000 to 1500 meters from the formation.
		06.48	BD 4835	Boat is positioned ahead of the convoy.  Dived for submerged attack because on the surface attack is only possible from long range, with associated low hit possibility.
			SW 3-4, Sea 3, high Swell rain showers, Vis. 2-3 nm
		07.02	Ran along on the course direction of the convoy now 225° at KF.  Convoy is just in a rain shower, can still not be seen in the periscope.  Came to course 240°, HF, to run a bit against the convoy because by sound bearings the enemy is positioned astern to starboard.
		07.06	Came to course 270° because by sound bearings the convoy has shifted further ahead to starboard.  Therefore the convoy must have zigzagged to starboard so that the boat is now on the port side and not as intended ahead of him.
		07.09	Astern bearing 90°T, range =1000 meters a destroyer with target angle 90°.  The destroyer was illuminated by the moon and was therefore only distinguished as a faint light spot.  For a stern shot or also a two-fan from tubes V and VI the data is too inexact to have any reasonable prospect of success.

		To 07.09		The destroyer is probably the port center escort of the convoy.
		07.13	3 torpedo detonations, medium range.  Afterwards a few star shells over the convoy.  The torpedoes were probably shot from starboard so that a turn to port by the enemy can be expected.
		07.16	2 further torpedo detonations at the same range.  As expected, the convoy turns about 30-40° to port.
		07.22	Came to course 290° (about attack course on the general course line).  About 7 to 8 shadows are distinguished ahead.  Range 2500 meters.
		07.30	2 large shadows, which just overlap slightly, come into a favorable shooting position.  The left shadow was made out as a 6000 GRT size freighter (2 masts, on the forecastle two pole masts).  The right as a 7000 GRT size freighter (2 masts, on the forecastle and on the stern 1 pole mast each, relatively large midship superstructure).
		07.33	Four-fan from tube 1 to 4 with aim point stern of the forward steamer, bow of the after steamer.  Target speed 9 knots, target angle = 90°, lead angle = 17.5°, depth 3 meters, torpedo velocity = 30 knots, estimated range 2000 meters.
			3 detonations after 2 minutes 32 seconds, 2 minutes 35 seconds, and 2 minutes 41 seconds.  The first detonation could still be observed on the right shadow in the after part of the ship before the periscope was over spilled.  By this the right steamer received 2 hits and the left steamer one hit.  This was also confirmed in the listening gear.  After about 1 to 2 minutes bulkhead cracking and typical sinking sounds in the direction of the detonations.
		07.40	The periscope comes free again. Star shells over the convoy.  After all around sweep in the direction of the shooting direction only 1 steamer is still distinguished, however the stern is already awash.  Because this shadow has only a forward pole mast it is the left.  The 7000-tonner must have already sunk.  Turned away to port, to bring tubes 5 and 6 to bear on the convoy.
		07.42	A large shadow is seen abeam to port, range = 800 meters, target angle 0°, is to be shot with tubes 5 and 6, came to GF to get suitable shooting data.
		07.46	2-fan from tubes 5 and 6, target speed = 7 knots, target angle = 80°, lead angle = 13.5°, depth 3 meters, torpedo speed 30 knots, estimated range = 400 meters.  Directly after the shot went the enemy turns away hard to starboard to target angle 180°, the torpedoes miss this target, probably the torpedoes passed on both sides.  However in the direction of the torpedoes there are still several shadows distinguished at greater range, close by one another, probably the bulk of the convoy.  The torpedoes were followed in the listening gear.  After 7 minutes 12 seconds and 7 minutes 32 seconds each one detonation, these must have been our two torpedoes which became hits almost at the end of their running track.  Up to the detonations both torpedoes were followed in the sound gear.  Due to the spread angle it must have been two different vessels.  Effects were not observed through the periscope.
		08.01	3 torpedo detonations.  Over the convoy a huge fireworks, about 30 star shells.  Any formation in the convoy can no longer be recognized, all drive wildly confused.  Came to course 40°, to get behind the convoy and to be able to surface, to reload tubes 5 and 6.
		08.10	2 further torpedo detonations.
		08.12	Because the periscope is overspilled for a few minutes and no all around sweep can be taken, went to depth A -50 meters.

		08.19	Loud destroyer sounds bearing 335°T, it only shifts ahead a little.  Went to depth A +0 meters.  Turned away to starboard, to possibly show the destroyer the stern and went to silent running.  Destroyer stops, probably to listen.
		08.28	Destroyer gets underway again.  Bearing is steady.
		08.34	2 depth charges, close.  Went to depth A +40 meters.  At silent running settled through slowly to depth A +55 meters.
		08.38	1 depth charge, close.
		08.39	Destroyer sounds shift slowly astern and grew fainter.
		08.49	Sound bearing very faint.   Went to depth A -30 meters and hard starboard to course 180°, to get further from the convoy.
		09.05	Surfaced.  In the morning twilight 1 shadow bearing 310°T, came to course 340° to get a closer look at the shadow.
		09.33	Came to course 50°, because the shadow gets larger quickly in the morning twilight.
		09.35	Another shadow bearing 10°T.
		09.48	At these shadows one medium freighter 1 destroyer is distinguished.  The suspicion that both shadows are lying stopped or only moving very slightly, was confirmed by bearings.
		09.51	Came to course 230°, initially to operate on the 1st shadow.
		09.57	3 detonations, probably torpedoes.
		10.04	2 detonations, probably torpedoes.
		10.08	1 detonation, probably a torpedo.  Shadow is now grown very large and was made out as a medium tanker.  Submerged to initiate attack on the tanker.
		10.13	4 detonations, probably torpedoes.  Held onto the destroyer at LF.
		10.20	Only ran at LF to not be heard by the tanker.  In the listening gear it was determined that the tanker tried to start his engine several times, however immediately stopped again.
		11.30	Shot from tube 5:  target speed = 0, target angle = 90°, lead angle = 0°, depth 3 meters, torpedo velocity = 30 knots, estimated range = 500 meters.  Detonation after 12 seconds hit aft 30 meters.  Directly after the hit the stern quickly settles deeper, it is entirely awash.  Then the aftership breaks off completely at the level of the hit, the other part of the tanker remains afloat.
		11.41	3 torpedo detonations.
		11.43	1 torpedo detonation.
		11.44	1 torpedo detonation.
		11.50	In the direction of the 2nd shadow explosion columns from torpedo detonations were seen so that probably another U-boat has hit this wounded vessel.  The rest of the tanker still floats without settling noticeably deeper.  2 lifeboats are launched from the tanker.  The remainder of the crew about 20 men float in the water, most already dead.  Held onto the lifeboats to take over the Captain.  However in the boats which are occupied by about 15 men, except for 3 young Europeans there are only Chinese.  The Captain is not there.  In the meantime one lifeboat capsizes so that these 15 men swim in the water.  On the lifeboats was on the stern a wooden sign with the name "EULIMA".  The name was also confirmed by questioning the shipwrecked.

		12.32	U-boat in sight on the horizon bearing 80°T.  The remains of the tanker have not sunk further.  To save the last torpedo below deck the tanker was shot with artillery, although the prevailing Sea State is the extreme limit for shelling.

		13.10	80 shells with about 70 hits are shot from closest range without the tanker noticeably sinking, although it has bit of a list to port.  The side of the hull and the over deck are already completely holed.  So as not to have to use a torpedo continued to shoot with the remaining ammunition.
		13.54	Finally after 120 shots with about 100 hits the tanker capsizes, however remains jutting a little above the water in a capsized condition however still floating.
		14.12	Now air holes were shot in the part of the tanker wreck protruding from the water with the MG C 30

	Comments of the Befehlshabers der Unterseeboote
	on the Kriegstagebuch of U-186 from 10.7. - 5.3.1943.
	First patrol of the Kommandanten with a new boat.
	The Kommandant led his boat with good tactical understanding and sense on the first patrol to a very pleasing success.  The attack on the "Wächter-convoy" on 23 February is considered especially fortunate and well done.
	Otherwise nothing to note.
