U-172 - 5th War Patrol

Translation by Christine Hillmann

Significant Events
Operations
12 Jun	14.00	U-172 was to refuel from U-118 on 12 Jun but the boat found the meeting place to be occupied by carrier-based aircraft.  At 16.00 depth charge explosions were heard related to the destruction of U-118.  The boat moved off to the south.
15 Jun	06.24	The loss of U-118 forced BdU to use U-530 as a tanker.  Refueling with U-530 was completed on 16 June.
28 Jun	04.43	The boat sank VERNON CITY misidentifying it as CORNISH CITY.
30 Jun -       4 Aug		U-172 entered her operations area off the coast of Brazil including the harbors of Salvador (Bahia) and Rio de Janeiro.  The boat sank three ships there before being ordered to return on 4 Aug with 63 cbm.
7 Aug	16.00	U-172 was ordered to meet with U-185 and the damaged U-604 to take over half of the crew.
11 Aug	18.40	U-172 met U-185 and U-604 taking over 9 cbm fuel, provisions and equipment.
11 Aug	20.04	Before the crew could be taken over a Liberator aircraft attacked, straddling U-172 and U-604 which were still connected.  Matr.Ob.Gefr. Schiemann was killed and two others wounded.  U-172 rudder was jammed 10° to port.  The boat was forced to submerge to avoid ramming U-185.  Several ballast tanks were cracked and the gyro compass and magnetic compass were temporarily out of service.  U-604's crew was taken over by U-185 and U-604 scuttled.
14 Aug	11.13	U-172 met U-185 and half of U-604's crew was transferred to U-172.
25 Aug	09.32	U-172 met U-847 and is supplied for economical return.
28 Aug	14.04	U-172 was warned of enemy activity on the Peining route.
31 Aug	18.35	U-172 was advised the Peining route was clear for her return.
Engineering
2 Jun	16.45	After an attack by aircraft an air vent line of tube IV leaked, the defective spot was in ballast tank 8.  As a result, the torpedo tube was exposed to outside sea pressure, thus the ability to dive deep was restricted.  The line was flanged at the pressure hull, sealed in the tube by a bronze cone but offered no absolute safety.
14 June	23.15 - 00.30	The starboard outer exhaust valve was repaired.
28 Jun	00.00	Bow cap of tube V could not be opened or closed.
28 Jun       11 Jul	00.00 01.15	U-172 was equipped with a FuMO 30 Radar set which employed a small turnable frame aerial with only 2x4 dipoles - 82 cm wavelength (formerly designated FuMG 42 gU).  In the KTB the boat refers to the radar as Fu.M.G. and notes on 28 Jun that attempts to get fixes were unsuccessful, the same on 11 Jul.
8 Jul	21.00-22.00	The exhaust valve was repaired.
24 Jul	08.00	Main rudder motor failed, maneuvering was by hand steering gear until repairs were completed at 13.45.
28 Jul	22.20-00.10	The exhaust valve was repaired.

				In the case it is hopeless for Höltring to attempt the return passage, U-604 is to be sunk.  For this following orders:
				1)  Höltring and Maus are to rendezvous in FK 3955.  Then are to proceed together to FL 1255.  There Höltring is to hand over all fuel to Maus, as well as half of the provisions.  As much as space permits, important equipment is also to be handed over.
				2)  Tonight Emmermann is to report by short signal arrival in the latter square.  There the remaining provisions are to be taken over and the crew of Höltring is to be shared equally between the two boats.  Subsequently U-604 is to be sunk.  After scuttling Maus is to report 'Yes' and both boats are to return to the base independently.
				3)  Further distribution of Höltring's crew on other boats is intended.  All positions marine squares.

				Six depth charges, four on portside, one between the boats and one starboard of U-604.  Opened fire with 20 mm and machine guns.
				Defended with all machine guns, hit possible.
				Very strong shocks, both boats disappear in the fountains of water.  Bomb impacts at 15 and 20 meters abeam on both sides of the boat.  Diesel engines full speed, lines and hose connections cut.
				Matr.Ob.Gefr. Schiemann killed in action by heart and neck shots while removing the muzzle plug of the 105 mm deck gun on the forecastle.
		20.06		Second approach-run steep from portside ahead.  Boat is increasing speed.  Altitude 20 meters, two depth charges, one of them detonates 5 meters away behind the stern, at a depth of about 20 meters.  Strafing fire.  Boat makes a leap forward.
				Matr.Ob.Gefr. Wagner seriously wounded by a shot in the chest and a grazing shot in the arm, Matr.Ob.Gefr. Meiβner slightly wounded at the eye by splinters.
				Several breakdowns.  Rudder jammed to port at 10°.
				All boats are zigzagging at full speed one around the other giving protection to each other.
				In doing so, I'm continuously in ramming position with U-185, which has not the slightest notion of my rudder failure.
				Both machineguns out of action.  The LI reports the boat ready for diving.

				Went to A +20 meters.
				Damages repaired.  Gyrocompass is still out of action.  Magnetic compass temporally out of action.  Several tanks cracked.
