Note:  The positions in the table above and in the Google Earth patrol summary are derived from the KTB and in many cases do not match those set forth in authoritative references such as Jürgen Rohwer, Axis Submarine Successes of World Wa r Two or the Uboat.net website.  The goal here is to present the picture relative to the U-boat and not the absolute position that the ship was attacked or sank.

 

This KTB uses the depth notation "depth T = xx meters"  Under this scheme, the actual depth was twice the depth given after T = so for example, if the KTB entry read "depth T = 50 meters, the actual depth was 100 meters.  This was intended to hide the actual depth for security purposes. This notation was used from about January 1940 to December 1941.  In these KTBs, depths written without using "T =", for example "dived to depth 35 meters" were not so disguised.

		25.08.41	Sea area between Iceland and the Faroes	The cruiser is positioned behind the freighter (prominent fighting top).  Enemy course apparently 130° to 150°.  A destroyer is positioned far out to the NE.  The strong protection is remarkable, perhaps a troopship from Iceland.  The freighter has a large broad stack immediately behind the large bridge, 2 masts.
				Moved off and maneuvered ahead.  At first slowly gaining at AK .
		20.00	AE 6774
			SE 2-3, Sea 2, overcast,  Vis. medium
		20.28		KR-KR:  Auxiliary cruiser, cruiser, 2 destroyers square AE 5995, course SE, high speed.  U-652.
				This Radio Message applies to "U-570" which may still be positioned to the south.
				Changing visibility conditions.  At times the enemy is completely lost from sight, when he reappears he has moved further ahead.  He zig zags about 30° to both sides around 140°, however, the legs are longer to the south.
		22.30		I want to give up the battle, however, just now the legs to the east become longer again.  Continue on.  Now I can take position on the other side on the dark horizon, the zig zagging has ceased, the enemy comes on faster.  The brightness of the horizon constantly changes.  Now it is the brightest even in the south.
		23.00 -
		23.50		Approached from the SW.  However, while approaching it has been getting light due to the cloud cover breaking up so that I must turn away again and get ahead again.  On this side only 2 destroyers.
		24.00	AE 9181
			SE 3, Sea 2-3, cloudy, Vis. medium
		26.08.41
		00.37		The SE horizon is darkest, approached from there.  On this side 2 destroyers, farthest behind a vessel of unidentified type.  On the other side of the steamer are 2 destroyers, one of which may be a cruiser (2 stacks, 1 thick, prominent mast). Formation of the convoy in Sketch 1.  The stern most steamer or escort grew bigger and bigger, the purpose of this formation is unknown.
				The forward destroyer (4 stacks, Type U.S.A. destroyer of the Churchill Class) wanders past and stubbornly stays at 800 meters distance in the brightest visibility path.
		00.44	AE 9185	3-fan from 1800 meters (beyond the screen).  Motor vessel estimated at 9000 GRT.
				3 G 7e, target speed = 14 knots, target angle  = 50°, range = 1800 meters, firing angle 344°, torpedo depth  = 3 meters.

		26.08.41	Sea area between Iceland and the Faroes	1 hit after 2 minutes 03 seconds running time.  Has a low exposed deck forward of of the bridge.  Steamer has a raised forecastle, motor ship of modern design.  High, black explosive pillar, steamer lies stopped.  Lights on the bridge wing which are answered by the forward destroyer.  The rearmost destroyer closed up a bit on the steamer.  Otherwise nothing happens at all, and I am able to run off easily.  No defense, no expected depth charge pursuit.  By turning the rear outer steamer has come to target angle zero abeam.  A large steamer, 10000 GRT, strangely positioned outside of the convoy.
		00.53		This steamer turned to port on a reciprocal heading, I turned for a single shot, in the meantime he goes further to starboard all the way around.  Nevertheless coming into shooting position.  However, the enemy is still turning.  The torpedo goes past.
				Torpedo depth 2 meters, perhaps to take one of the destroyers.
				Range = 1000 meters, target angle 60°, target speed 14 knots, firing angle 331°.
				Miss.
		01.50		I set off to reload.  Then went on the old enemy course to the old shooting location at KF, before me a thick shadow remains steady.  It may be the wounded steamer which wants to sneak off slowly.  Suddenly it is lost from sight.
				I see nothing more, afterwards I am far from the shooting location.
		02.15		A shadow bearing 160°T, shifting to starboard.  In the end I have to come to 240° in order to move around him to port.  It is the shot at or hit steamer which may have waited on the far side of the shooting location and ran off at high speed, 2 destroyers are recognized well astern and forward running in the old direction.  Whether the other two destroyers are positioned on the other side, can not be determined.
		02.40		2 bursting, loud detonations are heard in the boat, however, they do not appear to be from a torpedo impact. (distance 5 nm)
				The enemy steers 180°.  I do not approach any closer to him, because I am positioned behind him.  Zig zagging.
		03.19		The enemy is out of sight.  Could not determine the distance in the changing visibility (now very dark), therefore, no exact final location.
		04.00	AE 9419	Departed on course 270°.
			SE 2, Sea 2, overcast, pitch black, Vis. bad
		04.01		KR-KR:  Large steamer, 2 destroyers, square AE 9450, general course 140°, 14 knots, zig zagging.  Contact lost, moving off.                                          U-652.

		26.08.41	Sea area between Iceland and the Faroes	This Radio Message is meant for Gelhause who I suppose is in the Little Minch.  Before I had refrained from sending other messages because practically only the one target was in the convoy.
		04.45		Radio Message 0430/26/239:  An English unit reports a surfaced U-boat at 03.20 hours in AE 8661.  B.d.U.
				By our navigation fix and the time it cannot be us.
		05.15		Course 320° at HHF.  Nevertheless, have evaded to the north

			NE 4, Sea 3-4, Vis. bad-medium
		22.32		Radio Message 2151/26/258:  Depart attack areas on course 190° at cruising speed.  Because, however, cruising speed is ordered, I guess BF, but that is not on the intended line of advance, because I am not yet in the operations area.
		23.42		Radio Message B.d.U.:   Tuesday 01.00 hours steamer 9000 tons from convoy of 4 destroyers, apparently sunk AE 9185.  The second steamer escaped.  Behavior during the day and after the shot indicates inexperienced Americans.   Close formation.                   U-652    square AE 8193.
				I regard this radio message, even in this lengthy form, as necessary; the unusually strong screen and the weak defense was puzzling.
		27.08.41
		00.48	"KO"
		01.31	"OD"
		03.24	"OT"	The Radio Message was sent 2 times, after a misunderstanding by the radio-personne was sent 2 more times, and was not heard.  I then gave up sending.

		03.38		Radio Message 0146/27/269:  "U 652" operate on convoy courses 60°-90°.
		06.00		I operate on the ordered courses, calculating a speed of advance of 7 knots (as shown in the sketch).  I first search at the southernmost point assigned to me, calculating for the northern points, that the enemy must first break through to the SE - with the continually changing visibility I can hardly count on success.

		21.40	AE 7649	Smoke cloud bearing 295°T, seen very far against the red horizon.  Several clouds of smoke appear, apparently an outbound convoy.  Course 270°.  The clouds of smoke disperse again, only 3 remain intense on the horizon. While getting closer and raised high in the swell (it has calmed noticeably) 2 completely separate standing masts are recognized, soon the bridges are also found.
				Apparently destroyers, the other 3 are trawlers.  Imitating a convoy and exposed by the fact that they did not maneuver.  Search group is positioned in square AE 7566.  Ran off at high speed.
		23.00	AE 6772 upper edge	Large oil slick on the water, the air is saturated with oil fumes.
				Perhaps the search group belonged to the formation, which engaged U-570.  I believe, that one can hardly help here, looked again at the oil location for anything else, nothing further found.

		12.30   13.00		Immediate result:  When I want to go to periscope depth, suddenly at 12.30 hours 3 bombs fall at 28 meters which sound like aircraft bombs.  Some 1000 meters off.  Initially I remain at depth = 25 meters and then go to periscope depth.  Perhaps I have an oil trace and want to get as far away as possible.
				Without ever being heard, a destroyer with 4 stacks at a distance of 1200 meters bearing 70°T.  Target angle bow right 5-10°, apparently stopped.
		13.22		Course 200°, depth = 30 meters LF.
				Destroyer is the same type as in the convoy on 25/26 August 1941, one of the 50 American now in English service.
		13.28 14.17	Course 250°, LF Course 180°, LF	This was the destroyer who had thrown the bombs at 12.30 hours, so it was depth charges, nevertheless, I cannot explain his silent approach to myself.  I want to get away from this phantom companion as quickly as possible.
		14.20		Went to periscope depth.
				Nothing is heard in the sound gear, therefore the enemy should be at a greater distance than before remaining stopped at his old location.  Instead, he is again positioned at target angle 0° exactly behind me, also on course 180°, range = 1500 meters.  Now I can only imagine that he has me exactly in the sound locator and follows at the most economical RPM so that I do not hear him in the stern sector.  Even his auxiliary engines cannot be heard.  Around the destroyer an aircraft, apparently a large land-based aircraft flies at the lowest altitude.  I now suppose that the aircraft this morning had seen me and the destroyer was summoned here.  His cautious wait and see behavior, however, I cannot tolerate.  I must suppose that he wants to starve me slowly, because with the bright visibility at night I cannot expect to surface unnoticed at such a distance which he will likely be able to maintain, as up to now he has been successful.
		14.25		Because I must feel pursued and to escape other attacks, also in defence of his obvious attack or feint at 12.30 hours, I transition for an submerged attack.
				While running out of target angle 0° bearings I can clearly see the enemy, no flag, no markings, caps on 4 stacks. Otherwise an old tin box.

				Miss.  Attack course was calculated incorrectly.  Enemy's course was accepted erroneously as 230°, even though he was unambiguously on course 180° before.  Fast rate of change at the shot suggests the enemy's speed increased which was not apparent in the periscope, because the nearness demanded judicious use.  The enemy must have seen me at the shot, either because he knew I was there, or because he heard me perfectly in the sound-gear.  However, it only occurred to me later, that for these reasons, an undetected shot was hopeless.
				I actually shot from a target angle of 120°, however was no longer on the calculated attack course, I had to shoot with a large firing angle.  The fan ought to have hit somehow from a range = from 400-500 meters.  I turned sharply to the N and ran off.  The enemy apparently came from the port side, passed over us, and moved away in 130°T.  He gathered speed remarkably quickly.  I was just at depth T = 30 meters [60 meters] and turned at GF as usual on a cross course.
		14.47		5 depth charges, thrown a little bit over time.  Failures only in the diesel engine room (light bulbs).  Ran off further to the north and still turned and came to GF several times, because now and then the destroyer still comes close by.
		15.05	Course 330°	At silent speed in general direction NW shifted to depth T = 50 meters [100 meters].  In the E-room the bilge floods to the top through the leaky port stern bearing, it cannot be retightened.  Either I have lost the destroyer already or he follows me silently as before to lure me to periscope depth and then engage me.  Sound-gear impulses like a ticking watch are heard perfectly, and to be sure, direction finding.  However, they are weak and irregular.  Other impulses sound like those of our deep depth sounder, at substantial volume

			[Normally pumping from the regulating tank was done by compressed air but in this case they had to switch the controler to use the main drain pump.]

		20.30		Sweep at periscope depth is free.  At depth 20 meters reestablished the old trim condition of the boat using the main bilge pump.  As a result of too vigorous sucking of the pump, at depth 14 meters and with the bow down 15° the stern of the boat protruded above the surface.
		20.50		Again at periscope depth.  Destroyer bears 60°T on a NW course at about 6-8000 meters.

				Up to now no bearing marks received, direction finder secured.
				I set off away from the moon, to get on the dark side.  Now I am exactly behind him after the convoy changed course - he now steers NE.  At about 03.00 hours there is shooting ahead to the NW, and immediately star shells light up there.  This side "is stirred up".  Continued to maneuver ahead on the down-moon side.  For a short time the convoy seems to steer 0°. Against the long swells from NO it is difficult to make headway in the bright sea.
		03.49		Convoy still always seems to steer east.  Turned to approach. However, I cannot even approach the final ships, because they have blunt target angle and steer NE.  Forward on this side there is only1 destroyer.  Convoy has at least 5 columns, approximately 50 ships over a wide area of several miles
		04.10		Try to break into the convoy from astern.
			East coast of Greenland	Green and red flashes seem to suggest variations or turns of the individual columns.  They all steer on slightly divergent courses.
		04.50		Now I stand in the convoy ahead of the final ships and can soon turn for the attack.  I have selected a tanker, behind there are still enough other targets for the other available bow tubes.
				Suddenly from starboard, the final ship of the right column shoots with 8.8 cm.  The shots lie 300 meters away.  From port astern am fired at by 2 cm MG with red tracer over the tower and the net cutter.
		04.52		Turned to port to shoot.
				1 single shot each G 7e on a tanker, 7000 GRT and a freighter 4000 tons.

				Ran off between 220° and 150°.
				In the sound gear propeller sounds from 2 vessels, rapidly beating propellers, which are possitioned astern to port and starboard, of these the port one seems to be equipped with S-gear.  The escort to starboard stops frequently.  Because I have a lot of self noise under upper deck after the torpedo transfer, I cannot completely rely on the testimony of the sound man with respect to the sound-gear. Ticking sounds with a second beat, between them tweets.  Only this can be concluded with certainty.
				No matter what I do, the two of them always move out to their old positions after a while, Volume varying between 2 and 5.  Then one hears sounds, as if lines or gear were thrown overboard.  Even if I turn 180, the propellers come back again.  I suppose some detecting device, but I do not understand the low number of targeted depth charges.

I am often hindered in maneuvering ahead, because I often must go at KF because of the approaching boats.

				Ran off for the return transit.  With 1 G7a, 60 cbm.  Still several detonations bearing 40°T (1 tanker tongue of flame) so I must assume that there is still a contact keeper with the convoy.  Only later I recognize that I have acted only from experience, not however, in accordance with orders.

		08.00	S 3-4, Sea 2, heavily cloudy	I cannot imagine, that these flying boats are capable of picking up a short signal and searching for an enemy with certainty in the indicated direction.  It is amazing that Schulze is also surprised at night by a flying boat while sending bearing signals.
		10.01	AD 7484	Thick smoke cloud bearing 160°T.  A single steamer on course 40°, medium speed.  Maneuvered ahead for a submerged shot, for this purpose tube V is reloaded.

		11.11	AD 7483	Crash dive for attack.
				The escort is a kind of torpedo boat or coastal patrol boat, painted dark green, in front a small cannon.  Circles continually ahead of the steamer, at the shot he passed on his starboard side and is positioned [with the steamer] astern to port.
		12.00		Day's run:     Surfaced = 251 nm

				Miss.  Unexplained.  Possibly incorrect speed estimate.  "true target angle" amounted to 120°.  At the low range the torpedo should still have hit.  The enemy's speed was higher rather than lower, the increased target angle set would have compensated for the speed set too low in the final result.  Enemy was a steamer of 9000 GRT (estimated), gray painted high superstructure, marked" Republica de Panama".  Name not read.
				After the shot went to depth T = 40 meters [80 meters].
		14.00		Although [at first] the propeller sounds of the escort in the vicinity were held, they subsequently stopped, however, reappeared again.
				Perhaps the escort has shifted his sector astern of the steamer or it is another, who from the outset had the stern sector and now approaches the

	Comments of the Befehlshabers der Unterseeboote
	The Kommandant must become even more steady.  The attack on 25 August was skillful and was executed tenaciously.  Do not save torpedoes and check shooting accomplishments!  On the 11th September the boat should have continued to search for contact to facilitate the attacks of other boats.  In convoys exhaustion of all torpedoes is not necessarily reason for retreat.
		For the Befehlshabers der Unterseeboote
		The Chief of the Operations Department.
