Note:  The positions in the table above and in the Google Earth patrol summary are derived from the KTB and in many cases do not match those set forth in authoritative references such as Jürgen Rohwer, Axis Submarine Successes of World War Two or the Uboat.net website.  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.

 

This KTB uses the depth notation "depth T = xx meters"  Under this scheme, the actual depth was twice the depth given after T = so for example, if the KTB entry read "depth T = 50 meters, the actual depth was 100 meters.  This was intended to hide the actual depth for security purposes. This notation was used from about January 1940 to December 1941.  In these KTBs, depths written without using "T =", for example "dived to depth 35 meters" were not so disguised.

				In Trondheim the assembly hatch was put on anew and sealed. The G.H.G. distribution boxes were dried. (3 distribution boxes were filled with water) the seals had not held tight.  In the morning half of the crew went on an excursion to the waterfalls.  The Kommandant reported to Seekommandant Kapt. z. S. Thiele.  Some of the people were accommodated on land with difficulty.  Trondheim can become an excellent U-boat base with appropriate development.  For now, however, still everything is still lacking.
		02.06.40		Final overhaul of the assembly hatch and G.H.G.  2nd half of the crew went on an excursion to the water falls.
		14.30		Departed to deep dive.
		14.57		Dived.  Assembly hatch is still leaking, already from depth T = 10 meters [20 meters].  The leaks, however, are smaller than before.
		16.00		Made fast Trondheim.  Fuel oil loading.  Assembly hatch bolts are reapplied.
		20.00		Departed Trondheim to deep dive.
		22.56		Dived.  Went to depth = 60 meters [120 meters].  The assembly hatch still had small leaks.  300 liters of water per hour.
				The reason for the leakage of the G.H.G. was evidently in careless shipyard work, while the cause of the leaking of the assembly hatch seem to be from a distortion of the pressure hull.  However, both errors could have been discovered in a pressure dock and repaired at home.
		03.06.40

		00.07		Torpedo shot from tube IV!  Range = about 300 meters.  Set target speed = 6 knots.  Recognized the range was too short before the shot, therefore, aimed off at the forward mast.  Would have had to hit at the range.   Explain miss by deep fluctuation of G 7a at the short range.  Torpedo was heard in the sound locator, therefore no pistol failure, but under steered.

		02.45		Steamer in sight!  Attempt to get ahead and close.  Steamer is running at high speed, 10 minutes steaming  results in approximately 14 knots.  Attacked.  Getting ahead is not possible because of high enemy speed, shot must be taken at long range.  Target angle about 105°.  Slight chance of success.
		03.22	AM 5296	Torpedo shot from tube I.  Range estimated at 3000 meters.  Running time 274 seconds.  Torpedo speed 30 knots.  Hit about forward 30 meters.  Crew goes to the boats.  Foreship burns and settles slowly.

However, I do not know on which one and where the boats are now, in the mean time, the boats positioned to the south of me must already be off or have found nothing.  A coordinated convoy operations is no longer possible.

				convoy position 17.30 hours BF 7755.  Course West.
				After that the convoy apparently observed and took bearings on the strong radio traffic in his sea area and determined that contact was held on him, and evaded by quite energetic changes of course to the west.  It is likely that during the night he returns to a northeasterly course.   One would have to shorten the reconnaissance radio traffic to a type of short signal to complicate the taking of bearings, otherwise the approach of groups is always disrupted.  If the enemy knows there is a contact keeper somewhere, he will usually be be able to force  it to submerge and shake it off. The change of course will not be reported, the other boats will push past.
		22.00		Because nothing is sighted, running further to the southwest is hopeless.  Therefore came to course 300° and ran across the estimated course the enemy will come to at darkness.

		01.25	BE 9359 upper-center	In the mean time the steamers have resumed their position in the formation.  Again approached.  Shot from tube III taken at about 1000 meters.  Turned for a stern shot.  After 114 seconds = 1600 meters the shot from tube III hit an overlapping ship that was further away.  Size about 6500 tons.  Stern shot missed, because in the rush the lead angle not set in the torpedo Gyro Assembly.  Ran off.  Gun boat runs behind us, can evade.  In the convoy green and white stars, turn on southeast course and thereby come again into the moon bearing.  Contact is lost for a short time, found again, ran ahead.  Attack at about 1200 meters.  Shortly before the shot the convoy zigzags toward us with a red star.

	Comments of the B.d.U.
	1.) An excellent war patrol.  The tenacious attack on the convoy on 19 June was exemplarily. 2.) Being seen by the "LONDON" - cruiser on the 14th of June may have induced the expected troopship from Cape Town to take evasive action.  After the attack of the ship's aircraft, the boat was certainly discovered and this should have been reported.   There was then no reason to forgo the attack on the Greek steamer which appeared soon afterwards. 3.)  The observations on the consequences of Radio Messages - utility in maintaining contact are misguided, since:   a) without using Radio Messages - which has been executed successfully in many cases with contact keeping reports, the attack of other boats is not possible;   b) Short Signals cannot have the richness (really just for positions) necessary for maintaining contact.   c) no case is known in which successful evasion was executed for DF-bearings on U-boats, rather   d) the acquired bearings were so inaccurate that evasion based on them could just as well have led to failure.  By comparison B.d.U. Secret Order No. 150 of 28 January 1940.                                                         Signed in draft    D  ö  n  i  t  z                                                    For the Befehlshaber der Unterseeboote:                                                    The Chief of the Operations Department.
