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.

Significant Events

Operations

27 Mar 11.55 BdU ordered U-154, U-126 and U-124 to steer for ET 50 to operate against heavy traffic reported by radio intelligence in Guinea Bay and against SL convoys.

1 Apr 16.00 U-154 met returning U-172 and transferred Oblt.(Ing.) Reinicke.

8 Apr 16.32 U-154 was given FF 40 & 70 as an operations area to intercept independent traffic proceeding from NW to SE.

19 Apr 20.45 Sector "D" on Route "A" was opend for attacks againt independent shipping and U-154 was assigned FD 57 to a depth 180 nm as new operations area. U-126, U 105 and U-515 were assigned adjacent areas to intercept independent traffic proceeding from SW to NE.

29 Apr 14.47 U-154 was assigned an operations area off the coast of Brazil (FC 70 - 80 and south of this as far as the lower edge of FK 40). U-128 was assigned a similar area to the south.

20-22 May U-154 resupplied with U-460 and then return to FC 10 and 80 as attack area (FC 10 is probably a typo for FC 70 in BdU's War Diary - U-154 returned to FC 70).

28 May 04.43- 04.46 U-154 attacked convoy BT 14 damaging three ships. Afterward the boat withdrew to the north for repairs and to reload upper deck torpedoes.

3 Jun 00.34 U-154's attack area was extended to the north as far as EP 40.

7 Jun 01.19 Failure of the Metox forced the boat to withdraw from the coast.

8 Jun 16.45 In view of the Metox failure the boat was ordered to occupy a relatively safe area until the exhaustion of her fuel supply (DP 8136 via DQ 1481 via DQ 8962 to EE 6334).

18 Jun 05.00 The boat began return transit with 61 cbm fuel.

29 Jun 00.00 U-154 met U-126 off the Azores, transferred a Metox and discussed returning together.

3 Jul 02.44 U-154 observed an aircraft attack on U-126 which resulted in the loss of that boat.

Engineering

28 Mar 16.35 A deep dive revealed that the port outboard exhaust valve was leaking. Tightening reduceds the leak but it could not be completely stopped.

25 Apr 16.00 A bad welding seam in fuel oil/ballast tank No. 2 starboard casued loss of 3 cbm. The leak stopped on its own.

19 May 02.24 Grinding mechanisms of both exhaust valves were inoperable.

21/22 May During the meeting with U-460 welding repairs were attempted on two tears in ballast tank 8 portside 20 cm below the waterline. Leaks were closed by half.

28 May 14.05 While submerged at A +80 meters to avoid a destroyer there were numerous failures (pumps, stern tube, exhaust gas valve, vents) which were repaired except for the auxiliary bilge and trim pump which rendered the boat only conditionally clear for combat.

3 Jun 16.00 From 2 June after noon the main bilge pump was only conditionally clear. Pumps only 70% of its nominal value under water and on the surface only 50%.

6 Jun 00.15 The FuMB could no longer be tuned. At 20.00 the Metox failed completely. There was no reception in the wave band of 150 to 220 cm.

		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. Closed, began 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 the screen behind the aft starboard escort on convoy course, closed 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. Convoy has in the meantime turned to 170-180°. The effect of hits on the targets not visible due to the indistinct situation, 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 approximately 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 not observed visibly, 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. The boat is not hit however.
06.04		Ran off to the east and reloaded. 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. Closing is not possible, 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.

		Anderson-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 and turned off. At depth A plus 80 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°.
15.15		Ran off to the ENE at low speed, in order to return again to the attack.
16.00	FB 9299	With periscope sweep ship still floating, however very deep aft. Stern is now awash. 2 Catalina flying boats remain over tanker, distance about 4 nm.

		speed 19 knots, ship is American of type "Mariposa".
		Steamer zigs to the right 20° range about 8000 meters about 30° bow right. Estimated 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.
		By diving the boat did not remain at high speed long enough to close the distance. 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 m 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 pointless and therefore not fired. Tail shot with now broad target angle is hopeless since range is too great. Feasible distance with shot tube I and IV: "about 500 meters".

At the same time as the searchlight is seen an enemy radar detection is made on 130 cm. No tone, only short, medium-high scratching volume 2-3. Detection first made by magic eye then acoustically. Aircraft flies from starboard astern of the boat to approximately 500 meters distance, then detects U-126 in the searchlight beam and turns toward her 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 from the tail turret on U-126. 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 appears as if U-126 dives. The forecastle can not be seen, the stern is raised high. No one is seen on the bridge.
	ENE 5-6, Sea 5, overcast, 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 the 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 firing opportunity 5 hours later the weapon functioned perfectly. Whether an operating error was present, could not be determined. Afterwards the gunner says he could not fire the unsafed weapon despite repeated strong pulling of the trigger.
		Since bombs were all intended for U-126 which apparently dove and is intact, the commander decides to crash dive when the aircraft turns away. 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 telephone, 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 telephone signals remain unanswered. The situation is unclear. If U-126 also dived, and is listening on the underwater telephone there should be an answer. If the boat remained surfaced, contrary to our impression, contact is now lost. It was agreed between the two commanders that in the case of detection by the enemy to continue submerged. From the conjecture of the commander that U-126 did not dive after the unsuccessful bomb attack but at the next opportunity, it may be that the distance is so large that underwater telephone communication is no longer possible. Therefore the decision was made not to surface. Crucial for this determination are the observation of the commander 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.

Commentary of the Commander in Chief U-boats

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

First undertaking of the Commander after taking over the boat (Schuch). The first operation for the boat into the South Atlantic. The attack on 8 May was unfortunately unsuccessful first because of a miss then because of pistol failures. Air protection made subsequent efforts of the Commander more difficult. The attack of 28 May was well done and skillfully driven. Success very pleasing!

Concerning the 3 July: The Commander 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 Commander a beautiful initial success.

Accredited successes:

1 Steamer	(8917)	GRT.	Torpedoed
1 Freighter	(7000)	"	"
1 Tanker	6000	"	Sank
1 Freighter	6000	"	"
1 Tanker	8000	"	"
1 Tanker	(8500)	"	Torpedoed

Significant Events
Operations
27 Mar	11.55	BdU ordered U-154, U-126 and U-124 to steer for ET 50 to operate against heavy traffic reported by radio intelligence in Guinea Bay and against SL convoys.
1 Apr	16.00	U-154 met returning U-172 and transferred Oblt.(Ing.) Reinicke.
8 Apr	16.32	U-154 was given FF 40 & 70 as an operations area to intercept independent traffic proceeding from NW to SE.
19 Apr	20.45	Sector "D" on Route "A" was opend for attacks againt independent shipping and U-154 was assigned FD 57 to a depth 180 nm as new operations area. U-126, U 105 and U-515 were assigned adjacent areas to intercept independent traffic proceeding from SW to NE.
29 Apr	14.47	U-154 was assigned an operations area off the coast of Brazil (FC 70 - 80 and south of this as far as the lower edge of FK 40). U-128 was assigned a similar area to the south.
20-22 May		U-154 resupplied with U-460 and then return to FC 10 and 80 as attack area (FC 10 is probably a typo for FC 70 in BdU's War Diary - U-154 returned to FC 70).
28 May	04.43- 04.46	U-154 attacked convoy BT 14 damaging three ships. Afterward the boat withdrew to the north for repairs and to reload upper deck torpedoes.
3 Jun	00.34	U-154's attack area was extended to the north as far as EP 40.
7 Jun	01.19	Failure of the Metox forced the boat to withdraw from the coast.
8 Jun	16.45	In view of the Metox failure the boat was ordered to occupy a relatively safe area until the exhaustion of her fuel supply (DP 8136 via DQ 1481 via DQ 8962 to EE 6334).
18 Jun	05.00	The boat began return transit with 61 cbm fuel.
29 Jun	00.00	U-154 met U-126 off the Azores, transferred a Metox and discussed returning together.
3 Jul	02.44	U-154 observed an aircraft attack on U-126 which resulted in the loss of that boat.
Engineering
28 Mar	16.35	A deep dive revealed that the port outboard exhaust valve was leaking. Tightening reduceds the leak but it could not be completely stopped.
25 Apr	16.00	A bad welding seam in fuel oil/ballast tank No. 2 starboard casued loss of 3 cbm. The leak stopped on its own.
19 May	02.24	Grinding mechanisms of both exhaust valves were inoperable.
21/22 May		During the meeting with U-460 welding repairs were attempted on two tears in ballast tank 8 portside 20 cm below the waterline. Leaks were closed by half.
28 May	14.05	While submerged at A +80 meters to avoid a destroyer there were numerous failures (pumps, stern tube, exhaust gas valve, vents) which were repaired except for the auxiliary bilge and trim pump which rendered the boat only conditionally clear for combat.
3 Jun	16.00	From 2 June after noon the main bilge pump was only conditionally clear. Pumps only 70% of its nominal value under water and on the surface only 50%.
6 Jun	00.15	The FuMB could no longer be tuned. At 20.00 the Metox failed completely. There was no reception in the wave band of 150 to 220 cm.
