		22.20     22.15	Came to course 125°.  Both diesels ahead GF.  Due to late decoding of both messages to us, valuable time was lost but precise and clear consideration shows that immediately on sighting by air the fat morsels we were already in a hopeless position.  Unfortunately an indication of course and speed is missing. But under the circumstances I have to assume, that it is for Norway. Unfortunately, the hopelessness of the operation tarnishes the initial joy and forces me to to come again to our old course and economical transit speed at 22.15 hours.
		23.18	AE 6599                                   Because unfortunately further and more detailed message are absent, in accordance with Outbound Orders and Standing Order No. 13 dived again (Crash dive for training).  Proceeded submerged at depth 50 meters.  The disappointment is still great.  We just departed a bit too early.

			Now propeller-like sounds growing louder in 55°T and 120T°, that with the turning of the boat shift in direction correspondingly.  Therefore no further doubt; it must be a remote sound [not from the boat].  Propellers?  Will the GHG compensate us for all the grief already caused and report a steamer?

				5000 meters.  No further searchlight.  Enemy comes in sight again astern to starboard.  Turned to starboard and opened fire at range = 3000 meters.  Aircraft immediately turned away.  Shortly before had thrown a light marker.  No on board weapons shot.  No further detection.

		08.20		"Naxos" detection (3 short detections).  Enemy turns and flies toward the boat at low altitude from port astern.
			I decide due to the low range to remain on the surface to defend.  At range = 3000 meters fire opened from all barrels and turned away hard to starboard and ahead GF.  Enemy turns away slightly to port and flies at about range = 3000 meters parallel to the boat.
		08.24		Outgoing Radio Message Beta Beta 0825/4/75:
				Was attacked by aircraft.  Naval square BF 4888.
				"U-763"
				(First after the dive it was determined that the radio room had encoded an incorrect square.  The square must be                                       BF  4988                                   )
		08.26		Enemy turns away to port and holds far off for the next approach.
		08.29		Enemy flies towards the boat from port astern at low altitude again (altitude = 50 meters).  Boat again goes to ahead GF and turns on opening fire away hard to starboard.
				Enemy (type Liberator Consolidated 32) with American markings) return fire with on board weapons and gets hits in the coning tower cladding and port side.  No personnel casualties.  Own hits in the wing and in center of the the fuselage.  Spurts of flame and smoke development observed.  Aircraft - after throwing bombs (6 to 8 units), that fall at about 120 meters distance abeam to port (high wall of water) - puts itself on the inner curve, shoots with on board weapons and thereby offers a good target.  Flies off to about 5000 meters.
		08.40		Aircraft turns to starboard for a new approach.
		08.41	BF 4988	"Shoot down!"  Aircraft tips over the burning right wing and explodes on impact.  Parachute jumps not observed.  Due to increased air danger and favorable flying weather (medium-high broken cloud deck; bright day; Vis. good) I decide to dive immediately.
		08.45		"Crash dive!"  to depth 60 meters.
			Nothing more was distinguished at the shoot down location with binoculars.  I must also accept that the enemy had transmitted and decide therefore to dive without running to the shoot down location.  It would be desirable for the boat to have information about the enemy-frequencies in order to identify a call for other forces immediately.
			The combat role suggested for the boat by the Swinemünde Anti-aircraft School proved itself (uninterrupted ammunition supply).  Shooting all weapons in sea and weather conditions was very beneficial.
			Great joy over this "consolation prize"!

			I have the enemy in my binoculars and order:  "Do not shoot!"  I see a "light cluster" which quickly falls to the water.  It is a new floating light marker.  6-8 bombs are noted as short impacts.  Enemy must have detected the "Aphrodite".  Continued to move off on easterly course.

		02.14	BF 8139	Enemy turns to port shortly before reaching the stern and throws 5 bombs in train, that fall in the water at a distance of 100-150 meters on the port side (time ignition)!  On board weapons shot from the stern turret and cockpit.  Hits heard in the boat.
				The enemy, on which hits were observed, quickly passed out of sight on the port side.

		04.16		Between the individual approaches the aircraft was repeatedly seen circling at 600-800 meters altitude.  It always passed out of sight again quickly.  Did not fire due to the great range (over 3000 meters) and so as not to give away our position and running off course.
				The enemy fire around 02.08 hours proved to be a mistake. The aircraft had not detected the boat, instead was certainly confused by "Aphrodite".  When the boat opened fire a light marker was immediately thrown to mark the last position, [the aircraft] flew off, located and turned for a new attack.  The approaches were much smarter and more dangerous than on the previous day.
			Lesson:  Do not always shoot immediately, if decoys are launched!  The possibility of escape is then much smaller!  Shoot only if enemy is in direct approach to the boat.  After sufficient running off from the light marker throwing location by "Aphrodite" use undisturbed diving is possible.

			Summary of the First Patrol.
			1. The young crew found their way quite soon after initial weather difficulties with the Atlantic conditions and justified the trust placed in them. The victories achieved in the Bay of Biscay were indeed self-defense, but have greatly strengthened the confidence of the men in their weapons. 2. The changing of the boot routine proved to be expedient only on the long submerged transit into the operations area and on the return journey. 3. When charging in transit in highly air-endangered area, the boat ran with "battle bridge watch" (Watch Officer, Bridge Mate and 6 not alternating lookouts) or with manned "Aircraft battle stations" (18 men on the bridge).  Advantage: (maximum reduction in danger of surprise, fastest and most effective anti-aircraft weapons use) outweighs the disadvantage of not being ready to crash dive when charging transit is necessary.  Bright, cloudless moonlit nights, are very unfavorable because then the enemy can attack the boat entirely by surprise without locating and without searchlight use. In moonless, dark nights with or without clouds the enemy is forced, to locate at an early stage to initiate the attack or to illuminate with searchlights. With occupied "aircraft battle stations" anti-aircraft weapons are fully operational without delay and clearly offer the best chance of firing or causing the enemy to turn away. 4. Transit by day (clear skies) provides, in my opinion best guarantee of not being surprised and should be optional for the Kommandant in all areas. The possibility of monitoring hostile aircraft frequencies would show the boat that other forces had been called and establish the optimum dive time with contact keeping enemies. 5. Own Biscay experience showed that Naxos localizations coincided with sighting the enemy or were reported later when the enemy detected the boat and not the decoy. (see observations of enemy radar use). 6. Fu.M.O. (Hohentwiel experience) could not be made due to lack of operational use in weather area. 7. The existence of a wide variety of noise buoys to deceive or as a lure (launched by aircraft) is very likely. 8. Taking along a medical rating (boat had a Sanitätsmaaten along) proved to be very useful. The state of health of the crew during the entire patrol was good to very good. (medical examinations were conducted on a regular basis.)
