				In accordance with "Standing Order No. 29" the diesels should be run, with consideration of the start time, every 4th day half an hour at AK.
				Fuel consumption with the fast running of the diesels amounts to 1/2 cbm - 12.5 cbm in 100 sea days, that means 6-8 days less in the operations area.
				On this basis I will refrain from carrying out the high speed run initially on the long transit and will do so in the operations area according to the situation depending on fuel inventory.

				The Morse call-sign B  R  Y  F is not listed in Gröner.  It might be a secret call-sign, however I have the impression that it is a modern new ship.
				Shortly before giving the coup de grâce the port diesel had to be slowed due to a broken valve spring.
				Because the 2nd steamer has passed out of sight, however it jumped in repeating the SOS call, and had certainly seen the bright illumination of the lifeboats, and initially the port diesel can only run at LF I gave up pursuit of the 2nd steamer.
				The matching speed and maneuvering ahead with enemy speed 15 knots as in the previous case  is barely possible.  Both diesels which made 460 RPM during testing at AK, can now make only 420 RPM due to high exhaust gas temperatures, that corresponds to the previous GF at 16 knots.  Already after a short times at 430 RPM the exhaust gas manifold glows red hot.

				That upsets my plans.  Previously I planned to use the full new moon period up to about 12 April.  The new moon is on 4 April.  Supply on 16 April means setting off on 1 April.  With still 108 cbm and 11 + 8 torpedoes it is a great pity.
				The question is up to when can supply take place?  It I arrive on 30 April is that early enough or will the supplier be withdrawn after a short time?

				The listening conditions here are greatly changing.  The first sound bearing was first picked up in 75°R, however at relatively low range.
				With the 2nd sound bearing the range was so great that the vessel was not seen in the periscope, however the bearing was nearly directly ahead, therefore lay in a very sharp target angle.
				As far as I know, the GHG is sometimes inoperable, is it either fully operable or completely inoperable.

				Because air is expected in the entire area, by day predominantly 5/10-8/10 Cumulus and Nimbus clouds prevail, believe it is correct to proceed submerged by day, to remain unseen as long as possible.  If the presence of the boat is known, I believe further successes are completely hopeless.

				The 2nd patrol lasted 104 days.
				1.)  During operation in the "Hartherz" patrol line own air made itself unpleasantly noticeable.  It was certain that the boat dived before own aircraft several times. Enemy aircraft must have been in the area as well, because detonations were heard and anti-aircraft shooting was seen following the air warning signal.
				2.)  On the transit into the Caribbean there were no special events except for the fruitless pursuit of the tanker.  The premature failure of both negative buoyancy tanks caused difficulties.
				3.)  In the Caribbean there are continual air and weak sea patrols.  In two cases the working together of two aircraft was determined.  The weather conditions do not allow remaining on the surface because hardly a day with a reasonably clear sky was encountered.
				Observation in the Yucatan Channel showed that day traffic is protected by air.  Nights no air.  Radar only in the Windward Passage.  Striking was the abundance of neutral traffic, including Argentinian.  Although there were often clear nights with good visibility, no dimmed vessel was detected after the sinking.  The main traffic in this area runs on the course line Yucatan Channel and west of the Pedro Bank.  This is supported by the continuous burning of the Cape San Antonio Lighthouse, which is headed for by the vessels.  In all the other areas passed through no traffic was detected.  On the outbound and inbound transits in the area just off the coast no air surveillance was noted.  It was accepted that this is limited to the Caribbean itself.
				4.)  On the return transit there were no particular events, also on the transit through the Bay of Biscay.
				5.)  Continually remaining submerged was a considerable burden for the crew with room temperatures of 29-33°C and high humidity in the boat.  There were no serious illnesses
				6.)  Mechanically, leaks of the exhaust gas valves and the strong noises at the starboard shaft were unpleasant.  From opinion here, the batteries be replaced because the potting compound has been heat treated 4 times, without having achieved lasting improvement.

	Comments of the Befehlshabers der Unterseeboote
	on the K.T.B. of "U-183" (Schäfer) from 24.12.42 - 13.05.43.
	Despite its long duration (104 days), the patrol brought only a consolation success.
	In particular:
	The Recognition Signals shot on 9 February by day and in the twilight were a mistake.  On 18 February the tanker should not have escaped unnoticed given the good visibility conditions.
	1 March:  the shadow lying athwart the boat's course should have been identified further in any case.
	From the reporting from 5 June [presumably a typo 5 March] to 16 March it is not clear enough, what considerations the Kommandant based his operations on.  Despite the unfavorably described listening conditions apparently too little emphasis placed on visual observations.
	The setting off to the southeast and staying exclusively submerged gave the boat no greater opportunities that would have been offered in the Yucatan Channel.
	On 22 March the sounds received should have been prosecuted with stronger measures.  Surfacing earlier may have been possible.
	The Kommandant should have requested freedom to maneuver earlier.  All together, with a little more initiative and imagination the operation would have been more profitable.
	The difficulties of the stay in the Caribbean are not underestimated, but fully appreciated.  Notwithstanding, perhaps more could have been gotten out of the patrol.
	Accredited successes:
	1 freighter              7000 GRT sunk.
		For the Befehlshabers der Unterseeboote
