The bad weather period of the last few days has shown that the boat is slowed significantly by the Sea State and sustaining the RPM results in greatly increased fuel consumption. Speed loss in Sea State 6-8 is 50-70%. A fuel calculation based on the naval square AL 2261 on 20 February and an inventory of 400 cbm shows that now for round trip at RPM for 8-9 knots requires 385 cbm, leaving only 15 cbm available reserve for a period of about 4.5 months. Therefore I sent a Radio Message to Leadership concerning the fuel situation. | |||||
The characteristics of the boat in a heavy Sea State are good. | |||||

14.35 | AL 2771 | The first steamer in sight to port bearing 150°T, approximate course 60°, estimated range 6 nm. Steamer was only distinguished 2 times briefly, when the boat was especially high on a swell, immediately turned towards and pursued, steamer did not come in sight anymore due to continual snow and hail squalls. Boat was swamped 2 times by heavy seas from astern. The type of steamer was a 1 smokestack steamer of the CANADIAN LINE (17-18 knots). | |||

I suspect that on our first sighting we saw one another because we were lifted very high out. I broke off the search after an hour because in the prevailing weather conditions it seems pointless and weapons use is not possible. | |||||
In the over running seas 3 restraining belts had their hooks completely broken. | |||||
The danger of breakage or staining of individual parts of the restraining belts exists most of all at the moment of immersion. Therefore, make sure that the lanyard of the belts are always slightly tensioned in order to avoid strong jolts. The easiest way to achieve this would be through a small attachment railing at about 20-30 cm from floor level. | |||||

The specified low day's run results from the consideration that with turns for 8 knots the boat will on average make 6 knots over the ground considering the Trade Winds and the winter half of the year in the south. Turns for 8 knots must be maintained as transit speed, because otherwise the boat cannot make the entire trek without another supply due to its relatively high fuel consumption. (In so doing a leeway of around 50 cbm was expected for operations) The boat has about 30% higher fuel consumption compared to the type IX D 2 at low speeds. | |||||

The order to be at the meeting point on 23 April means that from square DS 52 the boat must cover 6400 miles in 41 days. That requires a day's run of 156 nm per day. Because with RPM for 8 knots considering the Trade Winds and the time of year I cannot count on this day's run, from 13 March 1943 at 00.00 hours initially I will go to RPM for 10 knots to create a bit of leeway with the good weather conditions.

At dawn 4 drifting boats were sighted, 3 of which capsized with Malayans [illegible word] and the only floating boat (but overloaded) Englishmen. The weather, current and the condition of the boats make a landing any of the shipwrecked almost impossible. | |||||
It turns out to be the tanker CORBIS 8132 GRT with heating oil for Capetown. Course 200°, speed 9 knots. | |||||
25 minutes after "CORBIS" sank at a distance of 5 nm from the sinking location a heavy concussion in the boat, probably the tanker was first crushed at depth at this time. | |||||
The position and the course of the tanker lead to the suspicion that the routes are widely scattered and cannot be assumed to be only under the coast despite the favorable current conditions. | |||||

10.48 | Sea 0, high medium-long Swell | Mastheads abeam to starboard bearing 100°T, bow right 30°, steamer comes out very quickly, so that the order to crash dive had to be given immediately because going to high speed with the unavoidable heavy smoke development would betray the boat immediately. After 23 minutes the ship came in sight in the periscope. Initiated bow approach. Mirror flat sea, high medium-long swell, course against the swell. Boat broached three times at a distance between 1000 meters and 600 meters with the entire conning tower out and was seen. Thereafter the steamer ran on a ramming course. I attempted to get past ahead for a stern shot, the boat must have been picked up by the wake because the steamer turned after and remained in target angle 0°, boat could only be steered in depth at HF or GF. To avoid being rammed went deep. The boat was at depth 30 meters when it was overrun by the steamer. Maneuvered ahead in the lee (due to own strong smoke development) after surfacing with periscope all around sweep. Steamer zigzagged. After 2-hour pursuit range had increased about 1/2 nm. In addition, an engine failed so I broke off pursuit. Modern fast runner with passenger superstructure, well camouflaged, was a completely different color on both sides so that submerged for a time there was the impression that we were dealing with 2 steamers. The behavior of the steamer must be considered very clever. I suspect that he often sighted me during the maneuver ahead due to own strong smoke development because he repeatedly put me astern. | |||

2.) The boat can receive fuel from the Japanese boat if we keep running together. | |||||
3.) From 14 May the boats must continue on to Japan because the Japanese U-boat cannot give enough fuel for return transit to Bordeaux. | |||||
4.) The aim is transfer at the first acceptable weather position so that a.) Herr Bose gets to Japan quickly - Japanese boat plans to run at 18 knots. b.) with this our boat still has time to operate off Durban. | |||||
5.) On sighting the enemy we attack up to 70°E, from 70°E the Japanese U-boat attacks. The meeting point is the location at the moment of sighting of the enemy. After 10 hours on to full hours radio bearing signals, send and receive according to program from the first meeting 23 April 1943. | |||||

It had grown calmer. Signal lamp exchange, with preparations to begin transfer. The Japanese boat lay stopped athwart the seas and drifted very much faster than we. After a few attempts, I lay in the only possible position with the stern into the wind - stern in the direction of the Japanese U-boat. The entire transfer was performed in this position. Transfer lasted until 14.10 hours and was successful due to the very good work of both crews. All items were transferred safely, albeit with some very considerable difficulties, the extraction of the torpedo canister and transfer of the torpedoes were especially difficult, since the transfer had to be carried out without the rubber boat - which was far too small. | ||||
09.00 | Freshening to SE 4 | Almost all the lines of the take over harnesses were broken by strain; with the first torpedo the tail line broke and had to be re-attached to the now vertical torpedo with a lot of patience. If the boat were not pressure-proof at the level of the takeover harness due to negative buoyancy tank plating, the transfer of the torpedoes and delivery of the canister would not have been possible. The large dingy of the Japanese U-boat had been smashed on the transit by the seas. | |||

Boat experienced a strong shudder after expressing [the negative buoyancy tanks] shortly before oscillating at depth 25 meters. The approval of the posts at the vents showed that all the vents worked properly, likewise the light signal system in the control room panel showed no malfunction. The shudder was like grounding on sandy soil. The Torp. Mech claims to have felt a strong impact on the fore deck and then heard a low-pitched sound on the side of the hull. The boat suffered no noticeable damage. I suspect that a vent had jammed and first sprung lose at depth 25 meters, especially since up to the shudder the boat was very light and afterwards immediately heavy. A second possibility consists of striking a drifting object. Charted depth is over 4000 meters. Sounder is out of service. | |||||

It was to take the transmission and lubricating oil from the internal tanks through the vents into the already carried pumped main ballast and reserve fuel oil tanks through a makeshift line with a hand pump. By this measure the boat can remain in the operations area until 10 May and remain ready to dive in terms of weight up to the supply square. | |||

Because nothing was sighted for 3 days on the ordered traffic route with courses, that crossed all previously steered courses of sighted or sunk steamers, I suspect that inbound and outbound traffic to Durban has been shifted to the north because of the 5-6 sinkings. Therefore I intend to carry out a leg to the north from KP 97 to KP 91 to KP 59. | |||||

13.57 | Both masts in sight with crow's nests. 13.57 hours Crash dive. 14.20 hours one corvette and a modern destroyer in sight in the periscope, approaching the diving location at high speed. Ran off at high speed athwart the enemy course. 2-meter depth setting for the torpedoes is impossible due to Sea State and Swell. Went to depth A -10 meters to depth A +10 meters. Ships must suspect me, ran on listening courses. Asdic questionable, only brief sounds like falling pebbles was heard in the conning tower. Listening conditions seem very unfavorable, Volume decreased passing depth A -30 meters quickly from 5 at times to 0. 2-hour listening pursuit, no depth charges. | ||||
16.58 | Surfaced. I gave up going closer to the coast because the condition of the boat and low regulating tank fillings do not allow a long forced submergence. 3 exhaust gas valves and both propeller shaft bushings leak heavily. The assumption that the condition of the exhaust valves would be improved by 4-hourly grinding and the stern tubes by re-stuffing the packing was a fallacy, as this assumption applied only up to the daily exercise dive depth. It should be noted that since boat's commissioning at least 3 of 6 exhaust valves and both propeller shaft bushings always leaked heavily, the bushings were tightened just after the overhaul of the same before the start of the remote patrol by the Deutscheswerft A.G. The bushings of the stern tubes on this boat were shortened by Deschimag due to lack of space. | ||||
The boat proceeded one hour 10 minutes at periscope depth and at depth A -40 meters to A +10 meters for 1 hours and 40 minutes. In this period the boat took on 6 tons of water. Accordingly, for listening pursuit the boat it was necessary to pump 3 cbm per hour from the regulating tanks and 900 liters trim water out of the trim tanks, unless the main bilge pump was turned on. | |||||
Pump-able regulating tank filling when surfacing was still 3 cbm. | |||||

At range = 400 meters the aircraft was on the correct course for the wind. At this moment I gave the order to crash dive.

[U-180 had 6 fresh water cooled Daimler Benz diesels in three pairs] | Fresh coolant water loss has continually grown worse, the 3 engines had to be shut down temporarily. It turned out that No. 1 had seven No. 2 six, No. 3 five leaks in the cooling water jackets. Duration of repair (soldering) 2 1/2 days per engine. Since only one fresh water maker is operable - the other already failed on 23 March - as soon as there are leaks, it cannot meet the needs of the crew and the diesel so that the stocks must be drawn down. | ||||

The crash dive exercises to depth A +20 meters have shown: the boat goes to the intended depth only with forward diving plane hard [down], aft diving plane to 20° [up]. At depth A +10 meters aft diving plane to neutral, then oscillate the boat at depth A +20. At any lower diving plane position, the boat oscillates too early (propeller wake and high stability) and then can no longer be caught bow down even with diving planes subsequently placed hard. In the process greatest bow down 23°, flood center after 10 seconds flood aft after 22-23 seconds, express at depth 30 meters; stern is then below depth A meters after 110 seconds and below the water surface after 50 seconds. At higher speeds must flood aft quicker to avoid too large a bow down angle. The above attempts were carried out at transit speed - turns for 7 knots. | |||||

31.05.43 | South Atlantic | It is a fallacy to assume that the boat would be invisible to aircraft on leaving the surface because the white bubbles after expressing the negative buoyancy tanks is easy to see directly from the aircraft, these bubbles first appear [at the surface] after 120 seconds - when expressing at depth 30 meters expression is finished at depth A or A +10 meters - and precisely indicates the diving location again to the aircraft. Therefore it would be very desirable to avoid the air bubble when expressing by means of a corresponding technical modification (Japanese U-boats have just such equipment). | |||

The steamer was already out to the smokestack when sighted. It was seen too late because the horizon in the direction of the steamer was obscured by our own smoke. The order to crash dive had to be given immediately because due to the characteristics of the boat increasing speed to match speed or maneuver ahead generates such a noticeable cloud of smoke that the boat would be detected immediately. Initiated submerged attack and at range = 2500 meters shot two associated single shots. Luckily, shots missed, because it turns out later that it was a neutral - Spanish. The illumination conditions were unfavorable - against the sun - of the painted flag on the side of the hull only the middle strip was distinguished as a bright line and was thought to be wood cargo amidships. Check by the First Watch Officer and Ob.Sturm. gave the same impression. The red stripes over and under the yellow did not stand out from the ship's side at all. That it was a Spaniard was only seen first from a position behind, however clearly there. My opinion that it was not a neutral was strengthened by the Radio Message received on 5 June, in which the neutrals in our transit route were listed and at our location we were not expected to meet. | |||||

1500 to 2000 meters. The aircraft does not succeed in starting an abeam approach. After the second full circle the aircraft flies from astern to attack, at this moment the extractor claw of the MG C/30 broke, so that there were no shots during the approach. At the appropriate moment hard rudder. The aircraft flew over the boat astern in a turn and threw no bombs. It can be accepted that the aircraft did not bomb because they probably did not have us in their cross hairs, and the bombs would have gone behind the boat due to the turn. The machine gun fire from the aft quadruple gun after the overflight lay a bit too short. Altitude of the aircraft over the boat was about 100 meters. Own light anti-aircraft machine guns could not be used aft as a result of their mountings. Type 4-eigined Boeing, British markings. After the overflight I gave the order to crash dive immediately. I believe that with heavy aircraft, I can get deep in a timely manor if I give the order to crash dive immediately after overflight. | |||||

on the K.T.B. of "U-180" (Musenberg) from 9.2. - 3.7.43. |
|||
|
|||
First patrol of the Kommandant with a new boat. | |||
The special task was carried out as planned and was well considered. The boat coped well with the difficulties of first testing a completely new engine layout and gained valuable experience. The combat task had to step into the background because of the special circumstances of the patrol. Therefore the sinking of two steamers is especially pleasing. The behavior during the aircraft attacks was good, a shoot down can be accepted as likely. The special technical experience of the boat will be evaluated and considered separately. The boat will no longer be used as a combat boat. | |||
Accredited successes: | |||
1 steamer 8132 GRT sunk | |||
1 steamer 5166 " " | |||
1 aircraft shoot down likely | |||

U-180 reported on page 30 of the KTB under 24. 4. 43.: | ||
"Signalman guest sent aboard the Japanese boat. First Watch Officer set to the Japanese boat by rubber boat for welcome and discussions. Understanding is difficult, because only broken German or English was spoken. We agreed that we should first run together in the hope of better weather, since very good weather is required for the transfer with available means - 4 small light inflatable boats with net bottoms. Delivery of a torpedo canister - contents gun barrels and ammunition - as well as transfer of three torpedoes endangers the outer hull plating in rough seas; likewise the boxes with documents and drawings are endangered by sea water, especially since the packaging in no way takes into account a transfer at sea." | ||
The above excerpt will be sent in accordance consultation by 1 / Skl. Iga with Skl. Qu AU b with a request to examine the matter and to arrange for it to be done. | ||
