31.10 41 to Penang Shipyard overhaul. The Japanese shipyard worked with much zeal Mechanical engineering was especially good. However, due to labor shortage the entire crew had to participate. Reception and support by the Japanese U-boat Department was particularly noteworthy.

04.00 MR 8638

06.00 Enemy zigzags irregularly between 160° and 220°, general course 190°. Am positioned ahead, course 180°, speed 12 knots.

06.21 Dived to attack 73 RPM timed. After about 30 minutes the steamer zigzagged 20° - ran at GF on collision course. I decided on an ETO 3-fan at about 2500 meters.

07.23 MR 8797 [typo 8697] 3-fan tubes I, III, IV.

Bearing         = 275°

                         = 85.5° (left)

Lead angle        = 24.5°

Target speed    = 12.5 knots

Range             = 2500 meters

Spread angle    = 1.5°

                                                Miss - The decision to shoot an ETO 3-fan at long range was incorrect - especially since the fan consisted of a T 3 and 2 G7e of the old type with G7H pistol (speed loss 1.5 knots)

08.00 MR 8689

09.06 Surfaced - followed behind at 2 x GF. Had to go to GF after a short time, because exhaust gas temperatures were too high.

12.00 MR 8697 Day's run: 204 nm, 8 nm

9°47'N, 66°49'E

12.56                                                 The Chief Engineer reports that exhaust gas temperature on the starboard diesel has risen to 600°. On slowing to LF the exhaust gas valve of Cylinder 6 breaks.

15.53
Continued to hold contact on smoke cloud with the port diesel 380 RPM. Starboard E-motor HF. Due to heavy zigzag of the enemy, only settled a little astern. Diesel in service again. Got ahead at GF. After a short time had to go to HF again, because exhaust gas temperature was 600°.

16.00 LB 2329                              Degree by degree we work ourselves ahead with a slight speed advantage. Due to the zigzagging of the steamer the position is becoming more and more hopeless. My last hope is that the enemy zigzags back 160° and therefore we will be ahead of him in target angle 25°.

20.00 LB 2613                                 Just as the Chief Engineer reported the diesels could no longer bear such a load, we determined the enemy was coming towards us in target angle 20-30°. Perhaps taking advantage of this last chance, I ran with E-motor supplement to the diesels athwart the enemy's course into target angle 0°, in order to get into firing position even if there was a turn away. In order to shoot before the next zigzag, immediately turned away for a stern shot.

Because enemy range was underestimated in target angle 0°, despite lowest possible RPM range was unintentionally large. Therefore shot a double shot with aim point lead forward and after mast mast course 160°, speed 12 knots.

20.39 LB 2616 Tube V and VI fire.

Bearing         = 277°

Target angle    = 63° (left)

Lead angle       = 20.5°

Target speed    = 12 knots

Range             = 2000 meters

Running time    = 177 seconds = 2655 meters

Set depth 3 and 4 meters.

                                                 At an interval of 7 seconds 2 detonation columns arise at the after mast. Steamer settled astern strongly aft and amidships fire breaks out. The forecastle rises far out and stays nearly vertical for a long time.

20.49                                                 Steamer sunk. No traffic on the 600-meter wavelength. A modern American standard freighter Cäser 2 Class, clipper bow, raised forecastle, cruiser stern, round bridge, high mast on the bridge, the two ship's masts extend beyond and are shifted laterally to camouflage the target angle. Cannon on the stern and forecastle, anti-aircraft guns on the bridge, aft 2 anti-aircraft platforms medium caliber. 4 lifeboats and 1 jolly boat. This sinking was due in large part to the Chief Engineer and the diesel men due to their sense of responsibility and hard work. 9 underwater detonations ended the combat. Several times clocked 73 RPM at 12 to 12.5 knots. Estimated 7 0 0 0 GRT.

                                        The hunt brought us 176 nm to the south. Came to a NW course to catch Aden-India traffic again.

NE 1, Sea 1, 1/4 overcast, Vis. good

12.00 LB 2127 Day's run: 213 nm, 2 nm

9°17'N, 64°55'E             The high exhaust gas temperatures of the starboard diesel was due to clogging of the muffler from torn loose and crosswise sheet metal. The Chief Engineer has a new exhaust gas opening burned out in the forward edge of the muffler.

Target speed    = 11 knots

Range             = 1000 meters

                                                  After 50 seconds hit between the forward mast and the bridge. Steamer breaks after a short time with the forecastle underwater and remains in this position.

20.54                                              Because the position of the steamer has only changed a bit, dived to listen. In the listening gear light cracking and bubbling heard.

21.02 Strong cracking and bursting. Steamer sinks.

21.04 Surfaced. Steamer has sunk.

                                                Went to the largest lifeboat. On request the first name "MARIA ESPANIOLA", to my threats, the correct name was confirmed "FORT LOURINE", from Port Said to Colombo. When running off we determine that this ship did not exist either. By appearance it was a ship of type "PORT ADELAIDE" 8422 GRT.

Length of the ship - at 1000 meters shooting range in the binoculars only the side of the hull, flat decker with passenger deck, slim, canted smokestack, straight bow, cruiser stern, between the forward mast and the bridge heavy king post, raked masts, astern a deck house.

00.48                                                  Shadow bearing 23°T. Matched speed course 280°, 12.5 knots. Because there are only 2 hours until morning twilight, I angle in as close as possible during the maneuver ahead. The bow sea of the steamer shines so much that there is serious concern that I might be seen. We speed through the sea like a luminous arrow. It gets clearer by the minute. About 11 minutes before the beginning of morning twilight we are positioned in target angle 30°. Despite the phosphorescence I ran at GF, to get as low a shooting range as possible.

02.25 MQ 4658 Tube I and II fire, with hit point forward of the after mast.

Sea 2, overcast, good horizon, strong marine phosphorescence Bearing         = 30°

Target angle    = 69.7° (left)

Lead angle       = 17°

Target speed    = 12.5 knots

Range             = 1000 meters

Running time    = 56 seconds = 1130 meters

1st hit between smokestack and after mast.

2nd hit between after mast and stern.

True enemy speed 13.5 knots.

After a short time the stern goes under. Crew goes to the boats. After bout 10 minutes the ship is vertical in the water.

03.00 MQ 4658 Steamer sunk. By the silhouette in the comparison tables was certainly a freighter of type Cäsar 3. At 1120 meters by running time at target angle 70° in the binoculars - = 140-150 meters length. Estimated: 9 0 0 0 GRT.

03.05 Dived, proceeded submerged.

16.00 MQ 4649                            Because the steamer continues his zigzag from 260-310°, I believe we have remained unseen. Zigzags occur every 10 minutes irregularly around general course 180°. Speed 11 knots.

I maneuvered ahead to target angle 0° for the 260° zigzag. When the enemy came to course 310°, I ran towards at LF, to be in target angle 0° for the next turn to 260° for a stern approach. The shot must go within 8 minutes because at the next zigzag the steamer turns towards us at a short distance. Therefore I decided, if necessary to shoot from a broad target angle. Operated for course 260° at 11 knots.

                                               While maneuvering ahead to port a light emerged which turned out to be a small steamer with set position lights. However, there were no neutrality markings. Let him pass at a distance of about 3000 meters. Since he stays peaceful and we have a better one in before us, we let him sail on as a harmless naive

20.00 MP 5986                            By avoiding the vessel on an opposite course we are now in target angle 180° to our steamer and note his course as 295°. Maneuvered ahead at GF.

Turned in to attack, while running in we have doubts about the target angle, which suddenly seemed much large than would agree with our course estimate of 295°. Although I briefly run in at HF, the range remains implausibly large. I turned away to match course and speed again and decide, to maneuver ahead again to target angle 0°. Determined: Speed remains 9 knots, however course was 250°.

Hit at the forward edge of the bridge. An unusually sharp detonation. The entire ship disappeared in smoke and steam. When the visibility clears the ship is capsized and sinks by the bow.

            In the listening gear we hear aside from ticking S-gear impulses from time to time a double bang - suspect explosive locating. Since it apparently looks like a hunting group, I decide to clear the area after moon set.

20.30 MP 9119                      Surfaced - the same picture as before - star shells - this time in direction 270°T, range larger. By the bearing and distance, it must be another vessel then fired the first star shells. Ran off on 20-30° legs around course 90°. An attempt to launch Aphrodite failed, because all burst.

Independent traffic: 1) From 9250 on course 295° to 5990, from there on course 250° to 260° about 30 nm off the coast up to 7170. There turn off on NW-course. 2) From 3870 on course 250° 30 nm off parallel to the coast. Outbound traffic about 50 nm from the coast frequent small convoys. All naval square Max Paul. 3) Between Max Otto 6950 and 6756 traffic runs about on the 200-meter line and further direct under the SW-edge Island 6764. (Japanese did not count on the barrier). 4) Strong traffic line detected from Max Quatsch 5586 on course 280° and opposite course to 4456. From there suspect further to Max Paul 5390 and connecting with coastal traffic.

Sea defenses: Patrol vessels up to now only in Max Otto 6756 and repeatedly in 6880. U-boat hunter group with air in Max Paul 9110. Believe not continuous surveillance.

Air: Lively day air on steamer route up to Max Quatsch 5597 determined. As a result, encountered traffic. Flying boats especially in twilight periods. No indication of night air or radar. At convoy mostly day air. Land air base Max Otto 6764. Suspect flying boat base Max Quatsch 47.

Average weather: NE 4, clear, medium marine phosphorescence Listening range much greater than day visibility. In new moon period good success by diving to listen. Believe surprise operation by 4-5 boats, of these Bachstelz [Fa 330] boats in Max Quatsch 50-60 as very promising. Good prospects for 3 or more boats, also promising convoy hunt from Max Fritz 8820 to 6790. Operation in new moon period undisturbed because Japanese operate mostly in full moon period (submerged attacks).

Lead angle       = 21°

Target speed    = 11.8 knots

Range             = 700 meters

Despite meticulously exact matched speed data and low shooting range nothing happens.

22.24                                                After 17 minutes running time a strong detonation, which caused major concussion in the boat. Thereafter 4 light detonation, then calm. Tanker ran on with wild zigzags. Assumed: end of run detonator, unfortunately as with all Lorient Etos of the patrol. Because the tanker ran on at the same speed as before, and our last torpedo was shot, surfaced, continued return transit.

A short time later the nearest destroyer with bridge and smokestack out. Target angle broad, bow left, range 5 nm. Course about WSW in broad line abreast.

                                              According to Radio Message the boat was flown at by carrier aircraft on night of 2 May. Carrier group at the meeting place. Attack attempted. Central Atlantic worse than Bay of Biscay. Suggest supply EJ 16 under land. 23 cbm, provisions at most until 15 May. Naxos out of service. "Seehausen"

For me the Radio Message was a kick in the head. Had Seehausen made his condition clear in his numerous Radio message, I would have been spared a lot of trouble and some worries. Taking into account the plight of a comrade (which in fact did not even exist) I have fully exposed the boat and crew in the full moon nights in the carrier area. Regardless of the fact that since Cape Town for the most part my crew fed on only hard bread and dry potatoes and cannot get home with our lubricating oil due to the detour, the only goal before me was to help a comrade. In addition to all that our transmitter has failed, we can not even point out our own position.

Contents: 1) Previous objectives settled.

2) From 11 May sunset supply: Waldegg - Seehausen in DS 5746. Hellriegel - Lüdden in DR 5897 . . . .

3) . . . report, if not met by 14 May lightness.

For me this gives the following situation:

1. Direct transit to the new supply place is via the position of the carrier group.

2. Route about 600 nm. Because with the current full moon and proximity of the carrier group night transit is impossible, the area itself cannot be reached by the morning of 14 May

3. As it is impossible to reach Leadership and Hellriegel concerning the situation (transmitter failure), I would be left completely hanging by my too late arrival.

4. If the current high lubricating oil consumption persists France can no longer be reached.

5. Provisions are sufficient with continued restrictions for 45 days. For the above reasons I decide to proceed to the Canary Islands and decide there, depending on the lubricating oil situation, if it is necessary to break off the patrol. Hellriegel is not in good shape, but his situation is in no relation to my predicament.

	15.53	Continued to hold contact on smoke cloud with the port diesel 380 RPM. Starboard E-motor HF. Due to heavy zigzag of the enemy, only settled a little astern. Diesel in service again. Got ahead at GF. After a short time had to go to HF again, because exhaust gas temperature was 600°.
	16.00	LB 2329 Degree by degree we work ourselves ahead with a slight speed advantage. Due to the zigzagging of the steamer the position is becoming more and more hopeless. My last hope is that the enemy zigzags back 160° and therefore we will be ahead of him in target angle 25°.

	20.00	LB 2613 Just as the Chief Engineer reported the diesels could no longer bear such a load, we determined the enemy was coming towards us in target angle 20-30°. Perhaps taking advantage of this last chance, I ran with E-motor supplement to the diesels athwart the enemy's course into target angle 0°, in order to get into firing position even if there was a turn away. In order to shoot before the next zigzag, immediately turned away for a stern shot.
		Because enemy range was underestimated in target angle 0°, despite lowest possible RPM range was unintentionally large. Therefore shot a double shot with aim point lead forward and after mast mast course 160°, speed 12 knots.

		At an interval of 7 seconds 2 detonation columns arise at the after mast. Steamer settled astern strongly aft and amidships fire breaks out. The forecastle rises far out and stays nearly vertical for a long time.
	20.49	Steamer sunk. No traffic on the 600-meter wavelength. A modern American standard freighter Cäser 2 Class, clipper bow, raised forecastle, cruiser stern, round bridge, high mast on the bridge, the two ship's masts extend beyond and are shifted laterally to camouflage the target angle. Cannon on the stern and forecastle, anti-aircraft guns on the bridge, aft 2 anti-aircraft platforms medium caliber. 4 lifeboats and 1 jolly boat. This sinking was due in large part to the Chief Engineer and the diesel men due to their sense of responsibility and hard work. 9 underwater detonations ended the combat. Several times clocked 73 RPM at 12 to 12.5 knots. Estimated 7 0 0 0 GRT.

		Went to the largest lifeboat. On request the first name "MARIA ESPANIOLA", to my threats, the correct name was confirmed "FORT LOURINE", from Port Said to Colombo. When running off we determine that this ship did not exist either. By appearance it was a ship of type "PORT ADELAIDE" 8422 GRT.
		Length of the ship - at 1000 meters shooting range in the binoculars only the side of the hull, flat decker with passenger deck, slim, canted smokestack, straight bow, cruiser stern, between the forward mast and the bridge heavy king post, raked masts, astern a deck house.

The bow sea of the steamer shines so much that there is serious concern that I might be seen. We speed through the sea like a luminous arrow. It gets clearer by the minute. About 11 minutes before the beginning of morning twilight we are positioned in target angle 30°. Despite the phosphorescence I ran at GF, to get as low a shooting range as possible.

	15.43	Surfaced. The steamer is indistinct on the dark horizon, unfortunately, the west horizon [where the boat is] is still quite bright.
	16.00	MQ 4649 Because the steamer continues his zigzag from 260-310°, I believe we have remained unseen. Zigzags occur every 10 minutes irregularly around general course 180°. Speed 11 knots.
		I maneuvered ahead to target angle 0° for the 260° zigzag. When the enemy came to course 310°, I ran towards at LF, to be in target angle 0° for the next turn to 260° for a stern approach. The shot must go within 8 minutes because at the next zigzag the steamer turns towards us at a short distance. Therefore I decided, if necessary to shoot from a broad target angle.

		While maneuvering ahead to port a light emerged which turned out to be a small steamer with set position lights. However, there were no neutrality markings. Let him pass at a distance of about 3000 meters. Since he stays peaceful and we have a better one in before us, we let him sail on as a harmless naive
	20.00	MP 5986 By avoiding the vessel on an opposite course we are now in target angle 180° to our steamer and note his course as 295°. Maneuvered ahead at GF.
		Turned in to attack, while running in we have doubts about the target angle, which suddenly seemed much large than would agree with our course estimate of 295°. Although I briefly run in at HF, the range remains implausibly large. I turned away to match course and speed again and decide, to maneuver ahead again to target angle 0°.

	20.30	MP 9119 Surfaced - the same picture as before - star shells - this time in direction 270°T, range larger. By the bearing and distance, it must be another vessel then fired the first star shells. Ran off on 20-30° legs around course 90°. An attempt to launch Aphrodite failed, because all burst.

		Situation: Max Paul. Japanese and own observations. Valid for NE-Monsoon.
		Independent traffic: 1) From 9250 on course 295° to 5990, from there on course 250° to 260° about 30 nm off the coast up to 7170. There turn off on NW-course. 2) From 3870 on course 250° 30 nm off parallel to the coast. Outbound traffic about 50 nm from the coast frequent small convoys. All naval square Max Paul. 3) Between Max Otto 6950 and 6756 traffic runs about on the 200-meter line and further direct under the SW-edge Island 6764. (Japanese did not count on the barrier). 4) Strong traffic line detected from Max Quatsch 5586 on course 280° and opposite course to 4456. From there suspect further to Max Paul 5390 and connecting with coastal traffic.
		Sea defenses: Patrol vessels up to now only in Max Otto 6756 and repeatedly in 6880. U-boat hunter group with air in Max Paul 9110. Believe not continuous surveillance.
		Air: Lively day air on steamer route up to Max Quatsch 5597 determined. As a result, encountered traffic. Flying boats especially in twilight periods. No indication of night air or radar. At convoy mostly day air. Land air base Max Otto 6764. Suspect flying boat base Max Quatsch 47.
		Average weather: NE 4, clear, medium marine phosphorescence Listening range much greater than day visibility. In new moon period good success by diving to listen. Believe surprise operation by 4-5 boats, of these Bachstelz [Fa 330] boats in Max Quatsch 50-60 as very promising. Good prospects for 3 or more boats, also promising convoy hunt from Max Fritz 8820 to 6790. Operation in new moon period undisturbed because Japanese operate mostly in full moon period (submerged attacks).

At a distance of 50 meters the first two receive their blessing of fire. On the 2nd a fire starts up, the sails burn in two places. Because despite heavy fire the effect is relatively slight, I decide to ram. Speed setting diesel KF.
	19.14	MQ 6467	1st sailing vessel sunk by ramming.
	19.27	MQ 6467	2nd sailing vessel sunk by ramming.
	19.32	MQ 6467	3rd sailing vessel sunk by ramming.
		While ramming we determine that the cargos consist of cotton and sacks, crews of 10-12 men. Size estimated at 150-200 tons. They are stable, seagoing vessels, similar to small Danish and Dutch schooners in the Baltic.

	18.17	Dived for submerged night attack. To my amazement the sound room reports no sound bearing. Also in the periscope no shift determined. To be sure had the stern tube made ready.
	18.50	By my calculation the steamer should have been here in 18-20 minutes. The steamer must have stopped. Although we dove with a cloud shadow at the diving position is possible he saw a flash of the conning tower in the moonlight and grew suspicious. Came to a parallel course and from the sound room came the report: "Steamer started and is picking up speed." Later: "90 RPM". Shift out to the right determined. Switched everything for a stern approach.

		Hit under the smokestack. For a long time nothing could be seen because of the smoke and steam. The steamer stopped. Nothing happened over there. Ran past ahead to port. After 30 minutes there is hardly any change and also in the listening gear no substantial sinking sounds were determined.

		After the first hit I had time, to look over the steamer carefully: clipper stem, forward 2 heavy king posts, box-like bridge superstructure aft of ships center. Smokestack after edge of the superstructure. Mast deck house on after deck, cruiser stern. A comparison with the recognition table explained the aft hit. It turned out to be an American of the Cäsar 2 Class which ran at 90 RPM =15 knots, 7500 GRT.

Assumed: end of run detonator, unfortunately as with all Lorient Etos of the patrol. Because the tanker ran on at the same speed as before, and our last torpedo was shot, surfaced, continued return transit.
