Ship zigzagged half hourly 20° around general course. In the bright moonlit night I cannot angle in closer. Enemy bearing shifts slowly ahead. Auxiliary engines were used (at 440 RPM 16.5 knots). The bearing seems to steady. The starboard clutch slips momentarily. After 10 minutes it is in service again. The bearing continues to shift ahead. After 2 hours 15 minutes the enemy bears 245°T in another 10 minutes 270°T. I give up the fight as hopeless because he can do better. |

Now I'm exactly ahead of him and dove. Ran to meet at LF until I was able to find out more about it. 2 columns each of 4 ships staggered with on another. Forward screen 1 destroyer, 1 corvette. Port screen 2 corvettes. Starboard screen could not be recognized. Later behind the convoy came 1 destroyer. I came on course 290° unseen through the screen. The target angle of the aft, closer column at a range of 3000 meters was already 35°. Supposedly the Etos run only 1200-1400 meters. Therefore periscope in and ran closer for 5 minutes. When I extend the periscope again, the entire formation has zigzagged about 70° to starboard and I am at a disadvantage. All nice big whoppers. |

During the last patrol the boat had an oil trace. Despite continuous examination it has not gone away completely. In the dock there were a few porous spots in the welds were repaired. Since departure on this patrol from the beginning there was a light oil sheen. As soon as the boat worked in the seas the sheen became a trace. This morning the trace became very heavy, as if the bilges had been pumped. If this problem is not found, I will be forced to leave the coast and to search for my salvation the open ocean. |

A steamer came in sight out of a rain squall ahead to port. Range 5000 meters. Bridge and superstructure were fully out. Masts capped. Boat stood before the light horizon and was recognized immediately. Steamer turned to starboard and ran off on course 120°. Because I was seen I no longer dived, instead steered a northerly course at high speed, until mastheads were seen just on the horizon. Then continued on at low speed. Masthead soon came high out. After he lost us the steamer turned and steered a northerly course. The bow was left, target angle 10°. |

Dove immediately so that he would not get us back in sight. Ran to meet him submerged. Because the bow was left, target angle 20° came to course 110°. As expected the steamer zigzagged from 90° - 30° every 5 minutes. At a range of 5000 meters he got far out the west and changed his course in 10° increments to 0°. The target angle was always 90-100°. Still a faint smoke feather in sight. Surface and pursued. |

The ship was American type C 1 with the radio call sign wtoh, 1400 GRT (According to Rower the steamer "J O S E N A V A R R O" 7244 GRT, in square LC 2197). Course was for the southern tip of Ceylon, probably with war material for the Burma Front. In the boats and rafts there were about 300 men.

After 2 hours I came to course 270°. Because the southern front with was quickly covered with rain clouds and large showers were moving there, dived for a test dive and all around listening. Very good visibility to the west and north. |

Day's run: 162 nm |
I slowly went higher and surfaced. The last bearing was 8°T. Also in the surfaced condition in the periscope nothing was seen. I came to course 20° and ran after. Nothing. Because in the extended periscope there is a height of eye of 9.5 meters and a large ship has a mast height of 30-35 meters I should see it at a range of around 18 nm. Nothing was sighted, therefore the ship must be further away. At a range of 20 nm and courses of 90-100° (Colombo or southern tip of Ceylon) it is a fast runner. Speed of advance 19-24 knots. Based on these considerations, I do not take up pursuit. |
|
| |

Because the listening conditions in this area are very good,
in the future I will dive for all around listening twice by day and twice by night. |

The diesel always smokes heavily. At increased speed (HF) the smoke is so bad that the boat can be compared with a steamer. In the prevailing clear visibility a maneuver ahead at the limit of visibility is impossible without being seen. Under these conditions one is forced to proceed on the basis of sound bearings. The evening high speed running of the diesel brings no changes. |

Shadow bearing 280°T. With the bright moon the visibility is very good. The enemy course is about 20°. I ran at highest speed to get ahead. The bearing shifts slowly ahead. After 5 minutes 4 more small shadows close by the larger and far from this formation a destroyer zigzagging at high speed. The formation zigzags irregularly. The boat is positioned exactly ahead of the formation. Which steers 70°. Dived to attack. Range 8 nm. At periscope depth soon comes in sight. The bow is now right, target angle 20°. Came to attack course 0°. |

At a range of 6000 meters the formation zigzagged to starboard to 120°. Speed of advance 18-20 knots. Now it is seen clearly the large shadow I take for a cruiser, type not distinguished. The close escort a destroyer, 3 corvettes. Forward escort one destroyer. The target angle quickly grew larger. Cannot get to shooting position. Escorts had "Asdic" turned on. |

Suddenly there were loud propeller and locating sounds heard in the entire boat. I want to go to periscope depth. However the sounds were so powerfully loud that I preferred to go to depth 2A -10 meters. I believed the boat had been detected. One should remain at periscope depth. It takes an eternity for the boat to go deeper. From depth 30 meters to 2A -1- meters 35 minutes. The density of the water changed constantly. As quickly as the sounds came they went away. Immediately went to periscope depth. Nothing seen. |

The supply situation is questionable. All types have a quite high percentage of failure. Bread, biscuit, pasta, oatmeal 30-50%. Rye flour (600 kg) completely inedible. Meat products, cocoa 30%, sardines in oil 100%, vegetables (cucumbers, sauerkraut, fruit, dried fruit 20%). I am forced to break off the patrol. There are still provisions for 75 days on board. How much of those are spoiled time can only tell. The stocks have been stored too long in the tropics. |

Sunset. Up to now the ship has still not come in sight again. Because in the changing cloudiness with isolated rain showers the visibility is only medium to good, and additionally his speed of advance is larger than my highest speed of 14.5 knots), gave up pursuit at 18.00 hours. Again a fast steamer slipped through our fingers. The boat's hull is overgrown and also the Swell is too great because in the ocean the boat can never never run at 16.5 knots at 425 RPM. |

[The entry at right is the comment of the reviewing authority, perhaps the Flotilla or B.d.U. and not U-178] |
Set lights and no bomb throwing speak strongly in favor of the idea that it was a standing normal reconnaissance aircraft and that the enemy did not expect a U-boat in a certain place. |

Comments of the Befehlshabers der Unterseeboote |
|
| |
on the K.T.B. of "U 178" (Spahr) from 25.11.43 - 24.5.1944. |
|
| |
|
|
| |
The Kommandant took over the boat at the halfway point of a long patrol. The long stay of the boat in tropical waters made itself very noticeable and limited operational capability. Surfaced speed, battery and especially the torpedoes had their efficiency strongly deteriorated. As a result many seemingly favorable attack opportunities were not brought to a success. |
|
| |
The behavior and accomplishments of the crew during the 14 1/2 month operation, mostly in tropical waters, are particularly noteworthy. |
|
| |
|
|
| |
Accredited success: 1 steamer 7400 GRT sunk. |
