		Turned to close. Westbound convoy.
		10-12 ships, number of escorts still to be determined.
		For the moment assume 1 destroyer protecting to starboard ahead or astern. Angled in, matched speed and began to maneuver ahead. Convoy course 295° on the 100-meter line round Cape Roque, speed 8 knots. Convoy formation 3 columns of 4 or 5 ships, distance between columns 500 or 600 meters, most ships ride high in ballast. Two destroyers each are stationed ahead and astern to port and starboard for flank protection. On zig-zag course. American ANDERSON type.
00.52		Enemy radar detection from escort on 136 cm, search mode.
		Deep, rasping tone of 100 kHz. 54 seconds required to search 360°, of that 8 second tone heard in Fu.M.B. Detection alternates during the course of the attack between search and continuous operation with partially roaring motion strengthens at distances of about 2000 meters from escort. After break-through of the destroyer belt the FuM.B. is secured. Since boat came upon the convoy from astern and at 05.30 hours the moon will rise, decided to attack from starboard.
		Broke through behind the aft starboard escort, on convoy course, angled in towards the starboard outer column at high speed. The destroyer on the port side changes position repeatedly and falls back behind the convoy. When the boat reaches the center of the starboard outer column, turned towards it to attack.

		Shot from tube II on typical tanker in the starboard outer column. Estimated 6000 GRT. Target angle right 105°, speed 8 knots, estimated range 2000 meters.
		Shot from tube III on typical freighter 6000 GRT in center column. Target angle right 100°, speed 8 knots, estimated range 2000 meters.
		Shot from tube IV on tanker type Empire Oil in left column. Target angle right 90°, speed 8 knots, estimated range 2500 meters.
		Next turned off for shots from tubes V and VI on tanker type BRITISH ZEAL in the starboard outer column. Target angle right 110° and 120°, speed 8 knots, estimated range 900 meters.
		Tube I, II and IV T 3 with M.Z. on, tube III, V and VI Etos. All depths 4 meters as ships were traveling in ballast.
		After firing turned on convoy reciprocal heading at A.K and ran off into the seas. While running off observed hits with flash and explosion column on 2 freighters and tanker type EMPIRE OIL, on 6000 GRT tanker faint glimmer observed.
		Immediately thereafter the destroyers shoot star shells. In the meantime the convoy is in target angle 170-180°. The effect of hits on the targets not visible due to thebroad target angle, in which the targets partially block themselves, the dazzling light of star shells and overcoming strong seas. In the boat in the order of firing, six distinct torpedo detonations were perceived. Stop watch times roughly agree with estimated distances.
		All hits, particularly the two from tubes V and VI, heard loudly in the boat. Hit effect tubes V and VI probably not observed visually, because the tanker was already at target angle 180°. Use of binoculars not possible due to spray. In addition glare caused by star shells.
04.50		Irregular star shell shooting by the destroyers, some of which are beside and over the boat.
		Judging from the number of muzzle flashes there are four of them. Apparently the destroyers are firing by radar detection, because each time the fire is aimed very well after the respective breaks. However the boat was not hit.
06.04		Ran off to the east and reloaded.
		Ran to the shooting location again. Intention is to look for survivors or damaged ships.
07.03		Flickering light from the shooting location bearing 220°T. Headed towards it.
07.30	Moonlit	Light is from the momentarily blazing deck lighting of a floating steamer. More is not distinguished, there are two destroyers circling the drifting ship at 4000-5000 meters. Did not conduct surface attack because of brightness of the moon. Brightness insufficient for underwater attack. Decided to attack underwater after the beginning of dawn.

		ANDERSEN-type destroyer circles with varying speed around the tanker. Stops from time to time, apparently to listen. Tubes V and VI are made ready for firing.
13.20		Shortly before firing a flying boat Catalinia-type is sighted, heading directly towards the periscope. Went quickly to 80 meters.
13.35		Again to periscope depth.
		Flying boat circles continuously very low around steamer and to above the diving place. Started approach again. Tanker moves fast and continuously turns back and forth in the wind, constantly changing its heading.
14.05		Destroyer to windward of the tanker, suddenly goes to high speed with bow angle approximately 0°. Destroyer observed by periscope to approximately 3000-4000 meters, then dived to depth A plus 80 meters and turned off. At depth A plus 80 meters numerous failures, disorders and leaks of auxiliary machinery and other important operating equipment occur (pumps, stern tube, exhaust gas valve, vents), whose repair is later necessary.
14.35		The G.H.G. partially operable, nothing heard. Again to periscope depth. 2 Catalina flying boats over tanker and the surrounding area, very low. Destroyer circles steamer stopping occasionally. Ship is now substantially deeper, stern is almost completely submerged. At the signal mast a red burgee. Distance now 6000-7000 meters target angle 160°. The target angle is still changing constantly due to the strong swinging of the ship.
15.15		Ran off to the ENE at low speed, in order to return again to the attack.

		speed 19 knots, ship is American of type "Mariposa".
		Steamer zigs to the right 20° range about 8000 meters about 30° bow right. Course is now 285°.
13.30	CF 4391	Double shot from tubes I and IV target angle right 85° Etos depth 6 meters, target speed 19 knots, distance 3500 meters. Missed.
		Due to the zigzag away the boat could no longer get close enough with the high enemy speed. Distance 3500 meters is too far with this fast ship. Explanation for miss is probably target speed estimated one knot too low. Steamer runs reliably 20 knots. That results in a difference of 2 degrees at 3500 meters or approximately 150 meters distance at the target. Estimated target length is approximately 180 meters. At target speed of 19 knots the right torpedo (75 meters ahead of the aiming point) should hit. A 1 knot speed difference results in a torpedo passage of 150 meters at the target to the left. Thus the torpedo probably passed close behind the stern. Too bad.
		Shot from tubes II and III, loaded with Atos, estimated range 3500 meters, sea state 2-3 and target speed 20 knots is pointless and therefore not fired. Tail shot with now broad target angle is hopeless since the range of the torpedoes is insufficient. Range with a shot tube I and IV: "about 5000 meters".

Aircraft flies from starboard astern of the boat to approximately 500 meters distance, then notices U-126 in the searchlight beam and turns, apparently because U-126 is located more favorably for the aircraft, towards U-126, dropping 4 bombs in train, flying over U-126 approximately 10 meters over the water's surface and then in a long curve to the right between both boats, firing at U-126 from the tail turret. The bombs are approximately at the position of the ballast tank 7 to starboard of U-126 30-40 meters short, U-126 does not fire. In the bright searchlight beam during the crossover it appeared as if U-126 dove. The forecastle can not be seen, the stern is raised high. No one is seen on the bridge.
	ENE 5-6, Sea 5, blue sky, starry, dark night, Vis. 3 nm, medium marine phosphorescence
		Own machine gun does not fire, despite the order to do so at the moment of illumination of the searchlight. The cause of the failure could not be determined afterwards. The machine gun was cocked and on safety. At the next check fire 5 hours later the weapon functioned perfectly. Whether an operating error was present, could not be determined. According to the gunner, he could not fire the unsafed weapon despite repeated strong pulling of the trigger.
		Since bombs were all too short, U-126 apparently dove and is intact, the Kommandant decided to crash dive when the aircraft turned away on the long curve between the boats. Before closing the tower hatch a flickering light and smoke is noticed at the attack position, apparently a flare and smoke-bomb. Nothing is seen of U-126 in the darkness.
		After crash dive to 40 meters immediately attempt contact by underwater telegraph, however receive no reply. In the boat 6-8 short dull bangs are heard, similar in tone to

		distant 3.7 cm cannon fire. Otherwise nothing heard. G.H.G. inoperable, no sound bearings.
03.05		Went to periscope depth. Nothing seen. All underwater telegraph signals remain unanswered. The situation is unclear. If U-126 also dived, and is listening on the underwater telegraph there should be an answer. If the boat remained surfaced, contrary to our impression, contact is now lost. It was agreed between the two Kommandanten that in the case of detection by the enemy to continue submerged. Hence the assumption of the Kommandant, that after the unsuccessful bomb attack U-126 dove at the next opportunity, it may be that the distance is so large that underwater telegraph communication is no longer possible. Therefore the decision was made not to surface. Crucial for this determination are the observation of the Kommandant and the entire bridge watch, that the bomb attack was unsuccessful, and that U-126 remained undamaged and dived even earlier than own boat.
04.00	BF 4744	Decided to continue on. Perhaps it will be possible to regain contact with Kietz at dawn.

Comments of the Befehlshabers der Unterseeboote

On the K.T.B. of "U-154" (Kusch) from 8.1 - 6.7.43.

First patrol of the Kommandant with an experienced boat (Schuch). The first independent operation for the boat into the South Atlantic. Unfortunately the attack on 8 May was unsuccessful first because of a miss then because of pistol failures. Air protection ruined subsequent efforts of the Kommandant. The attack of 28 May was well done and skillfully carried out. The success is very pleasing!

On 3 July: The Kommandant behaved correctly during the aircraft attack, an energetic search for "U-126" would have been appropriate. In addition to valuable experience, the first patrol brought the Kommandant a beautiful initial success.
