		30.08.42		However, the short pause of the engines was enough to let the tow line go taught.  The men on the forecastle can no longer hold the tow pennant.  The towing connection is only secured to the unsupported bolt of the tow hook.  When the tow pennant goes tight the hook does not hold.  The towing pennant jumps out.  In addition the hose is carried away.  When recovering his towline Vowe discovers that my tow pennant is not on his line.  Connection between the line and my tow pennant is lost as well as the pin of the tow hook because the bolt of the tow hook could not be released in time.  Another try to make the tow connection is put off, since I do not have a 2nd tow pennant, the tow hook is out of service and I cannot use a steel line in place of the tow pennant in the constantly increasing seas.  Masch.Mt.

		15.10 15.16	AJ 9727                            NW 3, Sea 3, medium heavy Swell, 5/10, 1029 mb +12°C	Mastheads reported coming out of a rain squall bearing 50°T.  When I come to the bridge, the mastheads are already very far out.  Moving ahead on the surface is no longer possible.  Therefore I decide to attack immediately and gave the order to crash dive.  Initially nothing is seen in the Atlantic swell. From the sound room there are continual reports, that propeller sounds are heard bearing 180°R.  Further, impulses like Asdic were heard. It sounded like the falling of a water drop on a hot plate.  So I ran towards the vessel  on course 50° and at 14.54 hours it came in sight again with target angle 0°.  The approach of the vessel in my wake, the unchanging target angle 0° leads to the conclusion that the vessel heard me on the surface and now searches to detect me submerged.  To gain distance abeam I run off on course 140° and then turn to run along on course 230°.  The boat is very difficult to hold in the powerful swell, therefore I only recognized the nature of the vessel later.  It is a freight steamer with passenger decks.  Forward on the forecastle there are 2 10.5 cm cannons.  Forward of the bridge to port and starboard a type of searchlight mast on which anti-aircraft armament is found.  The number of the cannons astern could not be recognized.  At the sinking location I later determined 2 aditional 10.5 cm cannons.  The ship had camouflage (mimicry).  For me it was clear that it was an auxiliary warship, that was stationed here as an auxiliary cruiser, U-boat hunter and weather vessel.  At 15.10 hours I turned to attack course of 320° - the Asdic impulses have now ceased - and shot at 15.16 hours a three-fan from a range of 800 meters.  The boat cut under after shooting.  After 50 seconds there were two impacts and detonations heard.  When the boat came up again the forecastle of the steamer can still be seen.  The boat then cut under again.  Now there followed two heavy detonations at intervals of half a minute.  The first was probably a boiler explosion, afterwards the breaking of bulkheads was heard. The 2nd was clearly depth charges gong high order.  There is no damage to the boat.  In coming up again nothing more of the steamer or remnants can be seen.
		15.55		At 15.55 hours I surfaced and ran towards the sinking location. Not much floats there.  3 men have saved themselves in a rubber boat.  Some of the people struggle in the water for their lives. Wreckage is hardly

		21.04		At 21.04 the boat was again at the sinking location.  Here there is a giant oil slick extending several miles.  After a long search I found 2 life rafts lashed together with 8 survivors.  Except for 2 whites all are Negro or mixed breeds.  All wear a similar uniform in which a life jacket is incorporated.  Head cover is a kind of car cap, The uniform clearly shows they are soldiers.  During the rather useless interrogation, because all were shouting and answering, I only learned that the name was Muskogee, Mukilted, or something similar.  Figures differ for the tonnage from 7000 to 3000 GRT.  I estimate the ship at 3000 GRT.

				The time interval of 11 minutes from the crash dive to the detonation told me that the bombs were not aimed for me and especially since at the aircraft sighting the boat was in the sun sector, we remained unseen.  Went to periscope depth.
		20.34		Nothing more to see.  Surfaced.
				Considerations:  Either it was a sea reconnaissance aircraft with the task of seeing if a convoy route was free of U-boats or it is the remote escort of a convoy.  Unfortunately the latter does not apply.  Despite increased watchfulness of the lookouts and good visibility in the next hours no convoy in sight.

		19.09.42		Because I am abeam of the head of the convoy I can still hope to reach shooting position on the last steamer in the convoy.  I run at HF on course 40° towards the convoy.  However nothing is seen.  Nothing heard at KF.  Visibility has again deteriorated to 1000 meters.

		20.45		Attempt to get ahead again, in the process was forced off a bit to the east by a destroyer.  In so doing the convoy passes out of sight.  Held contact on the foremost destroyer.  Destroyer steers general course 50°.  Slowly fought to get ahead.  Destroyer now positioned astern to port of me.  Steered 40°.

		23.50		Destroyer now steers 330°, it increases speed and passes out of sight at 23.50 hours.  Believe that pursuit in this direction is hopeless.  I suppose that the destroyer runs to the convoy at high speed.  Steered to the 24.00 hours point for the convoy in the assumption that the convoy had maintained course and speed since passing out of sight at 20.45 hours.
		24.00	AJ 6635	At 24.00 hours nothing seen.  Believe that the convoy has turned to port, in order to break through in the south on an eastward course.  Thereafter came to course 60°, 7 knots.

		10.35		Met with Köpke and Dierksen in the morning twilight.  Navigation comparison with Köpke shows a difference of over 40 nm, unfortunately my position from Dierksen is about 6 nm different.  The differences in navigation, which are now growing steadily among the boats, make it very difficult to find the convoy.
		11.29		This is proved by the following: At 11.08 hours a Short Signal was received from Jahn: Have contact on convoy square AK 4168, enemy steers 30°.  By plotting I must now steer 195°.  Luckily at 11.29 hours a Short Signal was received from Jahn:  Stand by for my bearing signals.  By the bearing signals the boat must go in 280°.  Had I operated on the reported position, I would have gotten behind.

		12.05		At 12.05 hours smoke clouds come in sight bearing 30°T.  I turn towards on a northeasterly course because by radio message the convoy steers 30°, and I want to maneuver ahead.  Köpke and Dierksen are still in my vicinity.
		12.50		At 12.50 hours a destroyer comes in sight astern to port bearing 340°T.  The destroyer is already out to the bridge.  The boats scattered radically.  Ran on course 50° so as not to give up the forward position. Since I'm closest to the destroyer, I draw him to me.
		13.05		At 13.05 hours the destroyer attempt to force me to submerged by artillery fire.  His impacts lie very inexact in bearing and in range far astern.  The distance increases.  Further the deterioration of the visibility is in our favor.  Therefore I don't think of diving.
		13.29		At 13.29 hours the destroyer passes out of sight in a rain squall.  I set off further to the north to get directly ahead of the convoy.
		14.00		At 14.00 hours the starboard flank destroyer comes in sight again, however I remain unseen.  Ran off on course 40°.  After 20 minutes the destroyer turns to the north and disappears in the drizzle.

		15.10		By plotting I am now positioned on the convoy course line, when in the suddenly breaking up weather a destroyer is reported astern.  Also this time I remain unseen and can get away at higher speed.  I believe this destroyer is the foremost escort.  It is a modern destroyer of the JERVIS Class.
		16.00	AK 4219	I now steer 50° and let myself fall back.  The destroyer comes in sight again astern.  I want to dive and attack the convoy, because I am certain the convoy still steers 50° and hope that I can get to it.

				When I begin the attack it is already too light.  Suddenly ahead (I am heading 167°) a star shell is fired.  A corvette close to 3 overlapping steamers I am approaching shoots with machine guns. I continue towards the steamers.  Now the port forward flank escort turns towards the convoy on a converging course to me.  I want to shoot now, because it is getting lighter.  The port forward flank escort presses me and in the mean time the port aft flank escort has come very close.  Shot at the 3 overlapping large steamers.  At 07.25 hours hours a single shot, at 07.28 hours a two-fan and at 07.30 hours another single shot.  Range = 2000 meters estimated, , target angle 90° and speed 7 knots.  The set depth was 5 meters.  The shooting data can be considered good.  That all torpedoes missed was laid to 3 factors:  1.  the medium swell, 2.  difficulties with the heavily rolling boat and 3. the long range.  The port forward flank escort is suddenly brightly illuminated on his starboard side.  I turn

		15.51		Surfaced.  Convoy is still in sight.  Aircraft circles several times  over the convoy and the passes out of sight in 300°T.  Both aircraft remained an amazingly short time with the convoy.  Apparently the action radius allows no longer stay.
		15.54		Crash dive for approaching aircraft bearing 240°T, 400 meters away.  Altitude about 200-300 meters.  Because I an unseen I remain at periscope depth to surface again.  Aircraft is not seen.  Am positioned ahead.  Day attack is not possible in the Swell.

				Crash dive.  Went to depth A -20 meters.  No aircraft bombs.  Unfortunately machine gun fire is heard.  Because nothing follows in the next minutes, I went to periscope depth.  Periscope is strongly fogged so that very little can be distinguished.
		16.16		I decide to surface, so as not to lose the convoy.
		16.18		On surfacing the aircraft is located bearing 90°T, 200 meters away, altitude 200 meters.  Immediately crash dived.  Went to depth A -20 meters.  Again no aircraft bombs, again machine gun fire.
				Now remained submerged, because I must assume that the aircraft are circling over the diving location.  After 20 minutes in the nearly out of service listening gear (GHG) fast growing louder propeller sounds were heard.  They were also heard with the naked ear and were identified as destroyer propeller sounds.  I gave the order to go to depth A +50 meters.  The boat steers course 100°.  The boat was overrun several times, without anything happening.  At 16.58 the first depth charge series of 11 charges was thrown.  The boat was already at depth A +50 meters.  The boat shakes strongly with the detonations.  The depth charges were well-placed and close over the boat.  Only very minor failures, like fuses and diving plane position transmitter were reported.  The destroyer comes about and

		17.07		throws at 17.07 hours the second series of 9 depth charges.  These lay still closer around the boat.  The boat shakes very strongly, the instrument pointers turn over themselves.  After the first  depth charge series the Chief Engineer gave the order to disconnect the instruments from outboard pressure.  I did not hear this order.  By mistake, the depth gauge was also switched off.  When the second depth charge series was thrown according to the depth meter the boat rose very strongly.  Despite E-motors GF and bow down apparently the boat could not be held at depth.  The Chief Engineer immediately noticed the error and had the depth gauge switched on again.  The boat is found to be already at depth A +100 meters.  I immediately gave the order to blow and catch the boat at depth A +110 meters.  The boat did well.  This caused no unrest in the boat.  At depth A +90 meters I flood again.  Apart from some fuses, there were no failures with these depth charges.  Both approaches of the destroyers were easily heard in the boat and I increased speed each time.  After the depth charges I went to depth A +80 meters.  Sound bearings showed that 3 destroyers were involved in the depth charge pursuit.  One each on my port and starboard sides to listen and locate, the third undertakes the work of the thrower.  At 17.30 hours came to course 250°, to increase the distance between the convoy and me.  I hope that as a result the destroyer group will be forced to leave earlier.  At the same time Bolde was ejected, which did not miss its effect, as the next depth charges at 17.56 hours showed.  They lay significantly further away.  Additionally at 18.12 hours two depth charges still further away.  At 18.30 hours I turn to course 260° and eject a further Bolde.  At 18.44 hours there follows the next depth charge attack with a series of 5 charges.  They are closer again, however give no more concussion in the boat.  Now there were two hours of calm.  The boat was over time heavier and more stern down, as a consequence the propeller shaft bushings leak heavily.  I take the boat higher to depth 100 meters and hope to pump from torpedo compensating tank to achieve weight and trim balance.  The attempt fails because the pump does not draw.  Pumped from the regulating tank.  An attempt to achieve trim balance by moving the water out of the E-motor room bilge by bucket chain does not gain much.  Went to depth A -50.  At 19.00 hours after ejecting a Bolde came to course 270°.  Afterwards the outboard closure of the flooding mechanism can no longer be closed.
		20.00	AL 1545	At 20.45 hours 3 further depth charges were thrown, which lay further away.  Since 20.54 in the listening gear there were no propeller sounds heard, which

		24.09.42	[Jahrmarktsfrosch = carnival frog = a signal cricket - like the noise makers carried by US Airborne troops on D-Day as a recognition signal]	which is not surprising with the almost completely worn out and useless device.  Only a locating sound, which sounded like the tak, tak, of a carnival frog, sheet metal bending under tensioning, is determined.  This sound was heard at an interval of 7-8 seconds and later an interval of 14-15 seconds.  Depth charged were no longer thrown,  The locating sounds suggested that the destroyer above had me well in his gear and waited.   Because in the meantime the bow room bilge was full of water and the stern down trim angle was always increasing, trimming forward was no longer possible because torpedo compensating tanks 2 and 3 and the forward trim tank are full, I decide to surface at darkness.  Reinforcing this decision was the strong self noise of the boat which was very loud in the listening gear.  The latter convinced me that the destroyer could hear me without difficulty.  The boat can currently be held only with one motor LF and one motor KF. If I have to pump constantly, this noise always gives a sure location for the boat to the destroyer.  My plan is to slowly go higher. At depth 12 meters blow with air.  When the boat get out immediately start the diesel to get out of visual range of the destroyer as quickly as possible. The best four lookouts get into the darkened conning tower while surfacing to get used to the darkness, so that they can immediately detect the destroyer when they reach the bridge. From 24.00 hours I bring the boat up slowly.
		25.09.42
		00.42		Surface at 00.42 hours.  The starting of the diesel comes off.  The destroyer was immediately detected by Mtr.Gfr. Hiltropp.  I ran off at high speed in direction 240°.  After 10 minutes the destroyer passes out of sight.
