			NW 5, 8/10, Sea 4, Vis. 10 nm	After lightness went to the port side of the tanker.  Taking over the tow connection and hose was difficult due to the Sea State.  The empty tanker yaws strongly while on my loaded boat on the over deck work can only be done roped in.  It is very difficult to hold course due to the failure of the gyro-compass.  I had to drive so that the hose was always loose.
		13.40 - 15.00		30 cbm fuel oil taken over.  The tow connection is very weak and broke despite the utmost caution without any particular rush in.

		02.05.42		While releasing the connection the hose line went under the forestem of the pitching boat and caught under the diving plane.  All attempts to get the hose free failed.  The last attempt by me to get the line free by slowly reversing, failed, the hose with the line tore.  Later on, it was possible to get the hanging down hose off the diving plane.  However it was still hung under the boat.  In spite of the bad experiences with free diving on the previous trip, I wanted to send the First Watch Officer with Tauchretter to determine the hooked location under water so as not to leave anything undone to save the hose.  While prepararing for this, the hose jumped off the place it caught and sank because the end cap loosened and the air escaped.  It is unlikely under the prevailing sea conditions the diving rescue evolution would have been successful.  In my opinion,it was too rough for the 2 badly maneuverable boats, especially since the maneuver was carried out for the first time by us. Seamen working on deck went overboard twice.  However, I had left the decision to carry out the supply to the more experienced tanker Kommandanten
		19.30	CC 8184	The loss of the valuable hose is regrettable, however, nothing was left unturned.  In the end it was only important for me to get the diving plane clear and get rid of the hose hanging from the boat to be ready for operations.  I declined the transfer of provisions, because one must drive close by where with the Sea State and the low speed there is danger of ramming.  Left the tanker with mutual good wishes.

		1x.x7		Incoming Radio Message from B.d.U. requesting to respond by Short Signal if Schacht operations area can be occupied.
				At the moment the radio communications are bad, I will first send the report in the evening.
		16.00	DC 5344	After careful consideration the following picture emerges:  It is 1400 nm to square DA 95 [northern Gulf of Mexico], I figure I will need 40 cbm assuming passage through the Florida Strait against the current.  So I would have about 20 cbm to operate.  In addition there is the low efficiency of my old batteries, about 55% with which I can not hold against the current, submerged during the day.  For the 8 night hours I need one engine for charging only, so that I cannot hunt and will only make a low day's run.  The Schacht operations area does not seem appropriate for me.
			SSW 2, 3/10, Sea 2, Vis. 12 nm

		10.35		A very lengthly fire on the water which was repeatedly driven back and forth over the tanker by the wind.  However the ship still floats.  Therefore fired a coup de grâce.  Hit a little aft of center, ship broke apart in the middle, however did not sink.  The tanks explode in series.

		16.44		After surfacing a large tanker in sight.  Very large and nearly system-less zigzags.  While maneuvering ahead a similar ship came in sight ahead to port.  Came over the horizon, avoiding between the first tanker is no longer possible.
		17.59		Dived, possibly we will have some luck.
		18.47		Tanker zigzagged past far to the north.  Met the survivors from HECTOR and reported these and was asked to pick them up by a land station.  If I had only stayed there.  Except for one stern torpedo I am out of torpedoes below deck.  I must reload now.  Due to the arising Sells and Sea State ran to the area off Grand Cayman.

		05.25		Because the ship still does not want to sink, artillery fire opened from 150 meters.  The ship began to burn, from all the timber deck cargo.  Otherwise no effect.
		06.08		Because a star signal was seen to the SE, I decide on a coup de grâce.  Despite depth setting 5 meters and hit in the engine room no effect.
		06.24		2nd coup de grâce fired.  Was a gyro failure and went past behind the stern.  Additionally apparently a cold runner.
		06.40		Ship worked in the swell and suddenly began to go deeper.  Thereafter it settled quickly.
		06.47		Ship has sunk.  From statements of the crew it was the American "ALCOA CARRIER" of 7000 GRT, on the way to Kingston Jamaica cargo piece goods.  Apparently the steamer had not transmitted.
		07.54		Sent a situation report to B.d.U.  Afterwards moved off to the NW to again to go to the rich area north of Grand Cayman.
