09.09.42 Beach" very intense searchlight that illuminates the fouling place about hourly. In the Fu.M.B. two locating transmitters are heard, alternately slowly increasing then decreasing, scanning the horizon, I suspect the transmitter is on land. From 03.25 hours the one of the transmitters is no longer heard. It was probably associated with one of the aircraft exercises that stopped around the same time.

03.44 Very intense activity by the air searchlights which search the sky very excitedly. Ahead to starboard at a distance of 5 nm a patrol vessel searches the water with a searchlight and Morses U twice and V once. Additionally, the large searchlight barrier is temporarily in action. I move off, because I do not feel comfortable with this and stop. Search lights finish. Because I am positioned at the diving location intended for the next day, I still charge. While starting the diesel searchlights illuminate, when shutting down "darkening". This repeats itself one more time.

04.00 CA 7358

05.16 I dive, in order to remain undetected at all cost. Put the boat on the bottom, depth A -60 meters. "Cape Henry" bearing 290°T, 16.5 nm distant. The boat does not remain statonary with 5 tons of negative buoyancy, it bumps and drifts with surging water, as in a spiral. In the listening device noises:

1) Chirping sounds, 1 second interval.

2) Depth sounding impulses or similar ticking in the entire sector, 12 impulses, recurrence 4 minutes, also heard in the boat.

3) Short, sharp irregularly sequenced explosive locating sounds. Heard in the entire boat.

4) Two short sequenced detonations (sounding).   I have heard during depth charge pursuit by English destroyers.

5) Very loud noises that arises from several small vessels (including 1 warship). Range = 1 nm that were not seen on diving.

6) Several aircraft bombs, medium and long range.

I do not believe that this is underwater detection against U-boats, especially not in these large numbers. Rather, I suspect an experimental station on land and I presume the vessels in the vicinity are here in connection with it, either looking for a wreck or the like, or performing exercises.

In the periscope and sound gear four outgoing and 1 incoming steamers (mastheads) determined, these are all exactly passing through in the center of the fouling place with courses about 130°, that is passing by buoy C 2B and the flashing red buoys. All vessels run on the 20 meter line then off to the north. On the basis of this traffic determination, I decide to carry out the fouling tonight with focal point in the center and deploy some of the mines in the southern sector.

Execution intentions: Surface during aircraft exercises for ventilation and to fill with compressed air. Battery is still well full. Listening and direction finding equipment will then be saturated by aircraft. Proceed submerged to the first deployment location, so that it cannot be determined by bearings or locating, and surface, to deploy with E-motors so as not to excite the seemingly attentive aircraft listener. Duration of deployment about 3 hours. With flooded over deck, to present as little to radar instruments as possible. I need to take into account heavy marine phosphorescence. The illuminated patrol boats will be blinded by their own lights.

The horizon can hardly be seen. Water is mirror flat, heavy marine phosphorescence., Wind 0. There are now two patrol boats there, the usual illuminated watch boat (corvette), 1 4-stack destroyer with set steaming lights and 3 white lights in the masthead. Two steamers well inside near the 9.7-meter point (in accordance with Standing Kriegsmarine Order B.d.U. No. 491, Paragraph 18)

Deployment courses according to plan, minimum distance to the watch boat 1200 meters, 2 mines out a little further, since we must angle off a bit from the patrol boat. Searchlight barrier is not in action, car headlights and individual searching of the watch boats is awkward. While surfaced, there were 2, at times 3, locating transmitters in operation that searched with rising and falling tones partly heard at volume 5. Every half minute 1 maximum of about 15 seconds duration. Accurate reporting by the radio room suggests that the boat was not detected.

                       Comments of the Befehlshabers der Unterseeboote

                       on the Kriegstagebuch of "U-69" from 15.8. - 5.11. 1942.

                1.) A good and well thought out execution of the mine deployment.

                2.) During further operations several success opportunities were thwarted by heavy air and zig zagging. However the Kommandant was again tenacious and ready for action to achieve success. In waters where the boat must remain submerged because of the proximity of land and surveillance, achieving favorable shot positions is very dependent on luck.

	09.09.42	Beach" very intense searchlight that illuminates the fouling place about hourly. In the Fu.M.B. two locating transmitters are heard, alternately slowly increasing then decreasing, scanning the horizon, I suspect the transmitter is on land. From 03.25 hours the one of the transmitters is no longer heard. It was probably associated with one of the aircraft exercises that stopped around the same time.
	03.44	Very intense activity by the air searchlights which search the sky very excitedly. Ahead to starboard at a distance of 5 nm a patrol vessel searches the water with a searchlight and Morses U twice and V once. Additionally, the large searchlight barrier is temporarily in action. I move off, because I do not feel comfortable with this and stop. Search lights finish. Because I am positioned at the diving location intended for the next day, I still charge. While starting the diesel searchlights illuminate, when shutting down "darkening". This repeats itself one more time.
	04.00	CA 7358
	05.16	I dive, in order to remain undetected at all cost. Put the boat on the bottom, depth A -60 meters. "Cape Henry" bearing 290°T, 16.5 nm distant. The boat does not remain statonary with 5 tons of negative buoyancy, it bumps and drifts with surging water, as in a spiral. In the listening device noises:
		1) Chirping sounds, 1 second interval.
		2) Depth sounding impulses or similar ticking in the entire sector, 12 impulses, recurrence 4 minutes, also heard in the boat.
		3) Short, sharp irregularly sequenced explosive locating sounds. Heard in the entire boat.
		4) Two short sequenced detonations (sounding). I have heard during depth charge pursuit by English destroyers.
		5) Very loud noises that arises from several small vessels (including 1 warship). Range = 1 nm that were not seen on diving.
		6) Several aircraft bombs, medium and long range.
		I do not believe that this is underwater detection against U-boats, especially not in these large numbers. Rather, I suspect an experimental station on land and I presume the vessels in the vicinity are here in connection with it, either looking for a wreck or the like, or performing exercises.
		In the periscope and sound gear four outgoing and 1 incoming steamers (mastheads) determined, these are all exactly passing through in the center of the fouling place with courses about 130°, that is passing by buoy C 2B and the flashing red buoys. All vessels run on the 20 meter line then off to the north. On the basis of this traffic determination, I decide to carry out the fouling tonight with focal point in the center and deploy some of the mines in the southern sector.
		Execution intentions: Surface during aircraft exercises for ventilation and to fill with compressed air. Battery is still well full. Listening and direction finding equipment will then be saturated by aircraft. Proceed submerged to the first deployment location, so that it cannot be determined by bearings or locating, and surface, to deploy with E-motors so as not to excite the seemingly attentive aircraft listener. Duration of deployment about 3 hours. With flooded over deck, to present as little to radar instruments as possible. I need to take into account heavy marine phosphorescence. The illuminated patrol boats will be blinded by their own lights.

Two steamers well inside near the 9.7-meter point (in accordance with Standing Kriegsmarine Order B.d.U. No. 491, Paragraph 18)

Deployment courses according to plan, minimum distance to the watch boat 1200 meters, 2 mines out a little further, since we must angle off a bit from the patrol boat. Searchlight barrier is not in action, car headlights and individual searching of the watch boats is awkward. While surfaced, there were 2, at times 3, locating transmitters in operation that searched with rising and falling tones partly heard at volume 5. Every half minute 1 maximum of about 15 seconds duration. Accurate reporting by the radio room suggests that the boat was not detected.
