		08.00	CF 3184 [typo actually CF]	Boat positioned by dead reckoning at the ordered position in patrol line.  Last navigation fix 13 June 00.00 hours had a few radio check bearings from Cape Vilano.

		13.29		Radio bearing from contact holding aircraft bearing 102°T and 109°T without giving bearing and distance
				Came to course 102°.

		15.21	CE 3191 [typo actually CF]	Smoke clouds bearing 37°T.  Came to course 28°.  Ahead GF.  Began maneuver ahead.
		16.26	CE 3191 [typo actually CF]	Short Signal:  Have contact on convoy.        U-89.
				No square given, because the position of the convoy is apparent from own bearing and the bearings given by Topp.
		17.13	CE 3159 [typo actually CF]	Topp reports contact on starboard forward corvette.  I hold contact on vessel with a masthead and must have detected the port forward escort.  When it bears 120°T and growing, put it astern and moved off at highest speed  in direction 300°T.  Despite setting the diving planes to centered and closing and blowing the waterproof bow, speed measurement comes to not more than 17.3 knots.  Because I assume the pursuing vessel is a corvette whose top speed is probably at best, at 20 knots, I hope to be able to shake it off
			NE 3, Sea 2, overcast, 1025 mb, +18°C, Vis. good
		18.10	CF 3154	Radio message:  From Lohmann: was forced off by escort at highest speed in direction 300°T. Naval square CF 3154.
		18.34		Radio message from Control:  Lohmann immediately report convoy position, Vogelsang check position.  For now assume the position from Topp is correct.
		18.44	CF 3119	Radio message:  From Lohmann:  Artillery fire.  Escort comes up slowly.  While running off continuing artillery fire.  (19 salvos, last range about 10000 meters).  From all the short salvos of 4 deduced a trailing TRIBAL or JERVIS class destroyer.  The intention of drawing the "escort" as far

				as possible from the convoy by running at highest speed is frustrated by breakdown of the port diesel (piston seizure).
		19.14		Crash dive.  The presumption that the now recognized destroyer would abandon the prosecution with increasing distance from the convoy turns out to be a fallacy.  Despite the reported only weak protecting forces, he remains tenacious and [while providing] comforting relief for others it does not seem promising.
		19.55		First depth charge attack (4 series each about 3 and more charges) at depth A +20 meters.
				Failures and damage:
				Gyro and magnetic compass.  Speed measurement system.  Order/loudspeaker system.  Numerous pressure gages unusable.
				Fuse damage:
				Both diving planes and main rudder, ruder indicator, various lighting circuits.
				Leaks:  Starboard outer exhaust gas valve, housing of the starboard and port inner exhaust gas valves, drain piping head valve torn in the control room, lubricating bushing of the flood valve linkage for main ballast and reserve fuel oil tank 2 port ran empty (10.5 cbm).  Internal contamination of both periscopes, radio direction finder difficult to move.
				Except for failure of the magnetic and gyro compasses, pumping difficulties and the first morale shock effect for an inexperienced crew no significant disability.
				Silent tribute to the beneficial preparatory work of the Agru-Front.
		21.18 - 22.20	No square/weather given because submerged, magnetic and gyro compass out of service and barometer out of adjustment.	During depth charge series after depth charge series, pumping difficulties are greatly complicated by jumping out of the rubber seals on the suction filter the main bilge pump.  The boat settles momentarily through depth A +120 meters and is held by blowing main ballast tank 3.  Break in the pursuit is used without regard to silent running to go up to depth A +40 meters to pump and work in the boat.
		21.30		Arising piston engine sounds.
		22.20		Sound pursuit with depth charge attack by 2 vessels.  Changing of the watch destroyer by corvette.
		23.55		Last large depth charge series.  Thereafter turbine sounds are no longer heard. Now only the escort with piston engine continues to hold contact.

		15.06.42	Entire day submerged west of the north Spanish coast
				When about 03.00 hours there were no further approaches by the escort vessel I decided to surface at 04.00 hours, however, a half hour later more depth charges.
		03.37
		10.19		Up to 10.19 hours single depth charges at longer time intervals.  A total of about 120 depth charges.  During this period and later large numbers of depth charge detonations whose direction could not be determined.  There must still be another [boat] forced to submerge.
				An attempt was made to steer a fixed direction under water with a miniature magnetic compass in a battery whistle of the Engineering Officer and in so doing a rudder amidships position of about starboard 7 was determined.  The more reliable direction determination remains the sound bearing from the escort.  Put off surfacing until dark because of failure of both the diesel and compasses.
		12.00		Boat was still detected by the escort several times.

		13.20		Overrun perfectly for the last time.  No depth charges.
		15.00		No sound bearings except for a clock-like ticking sound that changes in volume and is difficult to detect in terms of direction.
		21.10		Indistinct sound bearing like a small boat motor.
		22.52		Expected sunset for square CF.
		from 23.45		Prepared to surface.
		16.06.42	Sea area west of the north coast of Spain	Boat is prepared to attack with artillery, torpedo employment and destruction of the secret material.
			No square given because the last navigation fix was on 13 June and the compasses are out of service	While surfacing sound bearing of a piston engine bearing 310°T.
		00.19		Sounds were put astern.

			Wind 2, Sea 2, overcast, light drizzle, Vis. very bad	A NW wind was assumed and by the wind and Sea and with the Engineering Officer's department store compass steered a course assumed to be northerly.  Stars cannot be seen.
				At first there were difficulties starting the diesels.  Air supply from Bottle Group IV, which had to be shut because of leakage at the start of the depth charge attack, used as a reserve.  Compressed air was filled, battery charged and the elimination of depth charge damage addressed.
		07.31		Radio message from Lohmann:  Forced to submerged for 31 hours.  Depth charge damage.  Hope to repair with on board means.  Am missing Serial Nos. 128, 129, 148-177.  No compasses.

				Experiences and observations on lying on the bottom in the operations area:
				Prevailing surface current runs in a southwesterly direction.  Current on the bottom changes with each ship position, no noteworthy strength.  Boat lies fixed with 2-3 tons negative buoyancy.
				Between 15 and 20 meters water depth striking reversal of the current.  Boat runs with a trim of over 10° on the ruder.
				Sea water specific weight on the surface 1021 on the bottom between 50 and 70 meters up to 1.025.
				Water temperature on the surface +23°C on the bottom at 70 meters +9°C.
				The boat's internal temperature falls from +22 to + 12°C.  Due to the strong cooling great humidity increase in the boat.  (dripping cave!)  Heating the periscope is required.  After surfacing binoculars and sextant are only usable when preheated.
				Reliable sound bearings limited by water stratification.  Negative pressure occurs in the boot occurs through cooling without pumping out.  Because close under the coast due to the short nights there are at most 7 hours proceeding on the surface in which to receive the Radio Message Serial Nos. completely.  The transmitting periods of the German beam antenna lie unfavorably, so that no broadcast reception could take place.

		12.20		Patrol vessel mast bearing 265°T.
				From the experience of the first two encounters attempted to move off on the surface.  Patrol vessel comes appreciably closer.
		12.26	BE 4234	Crash dive.  Recognized at periscope depth as a corvette.  Small target angle and corresponding slight shift determined, up to 284°T.
		12.48		Boat is ready to attack, when all around sweep shows a destroyer at about 2500 meters bearing 249.5°T and target angle 2-5 approaching quickly.  Depth control is very difficult due to Sea State and Swell.  Quickly to depth A +50 meters.  Silent running.
		12.52		With increasing depths the listening conditions, which up to now in Sea 4 were unsatisfactory, were better.  In 165°T in the GHG a noise was heard that probably originates from the convoy steering a southerly course.  The distant corvette cannot be heard.  The sound bearing from the destroyer shifts from 265 to 310°T with changing volume and frequent stopping and starting (depth sounding impulses).
		13.16		Last sound bearing.
		13.22 - 14.15		On going higher in irregular, larger time intervals a total of 9 bright, quite sharp however harmless detonations in indeterminable distance.  The type of detonation was unknown to now.  They were initiated by a peculiar metallic percussion, which seems to hit the boat at the bottom and did not cause excessive concussion.  This "percussion" was followed by the actual detonation, which disappeared in an undulating ebbing bright noise.
		15.20		Boat went to depth A -5 meters.
				1 detonation at medium range.
