The goal here is to present the picture relative to the U-boat and not the absolute position that the ship was attacked or sank. |

Tanker is clearly distinguished. Comes towards me at a sharp target angle. Then the same as the first time, the tanker stops, turns, as I continued to approach, turns towards me at high speed and overruns the boat. | |||||
Usually I am not so inclined to relate all the enemy maneuvers to my attacking boat, however this repeated counteractions to my attacks makes me suspicious. | |||||

Day attacks are given up now. In spite of dependence on the buoys, the steamer route extends a few miles wide. The horizon is hazy, the steamers come in sight full size at only about 3 nm. Therefore, maneuver ahead is usually unsuccessful. Besides, strong air surveillance. Danger of being seen is great in the shallow water, strong sunlight, smooth sea and being limited to the forward periscope. | |||||
All together today through the periscope sighted or heard perfectly: 16 steamers, of these 9 southbound, 7 northbound. | |||||
Of these I am interested mainly the southbound, all of which are between Lookout and Hatteras at the beginning of twilight. Intend to run there. | |||||
23.50 | At periscope depth. Sounds of 2 steamers, northbound. | ||||
Now also the forward periscope has fogged up (inside) difficult to see. Sounds are very loud. Recognize dimly 2 full large tankers, led by an escort. It is about one hour before the onset of twilight. Hold contact as long as possible submerged. Gyrocompass fails. Nothing is spared us. In the periscope nothing is seen, but is heard well. | |||||

After one minute 0.8 seconds a powerful detonation. Fire column several hundred meters high, and the tanker is engulfed in flames. It was a large tanker of about 10000 GRT. | |||||
Short time later we are fired upon with star shells by the real escort who is still positioned further ahead probably with the other tanker. | |||||
The wind is positioned favorable and drives the smoke between us and the fire. Tanker lists heavily. The sky is obscured. Nothing is seen of the patrol vessel that we overtook. | |||||
Turn off at high speed to about 90°, to get to deeper water. Tanker is torpedoed in about 15-20 meters. The burning oil occupies a sector of about 40°. After about 2 hours the fire hearth disappears, oil on the water continues to burn. The tanker is sunk. Patrol vessel shoots star shells for about 1 hour, however ineffectively. | |||||
