		02.55		Boat touched bottom in 23 meters in square CA 2925 lower-right.
		05.06		Boat raised from the bottom and surfaced.  Ran towards the coast with E-motors LF unblown, over deck about 20 cm above the water.  I run well in this condition until the boat touches bottom, then, when the task is completed, blow and run off.
		05.52		Boat touches bottom in square CA 2925 upper center.
		06.05	Vis. about 100 meters	Nothing is seen of the shore, however the surf can be heard easily.  The [rubber] boat must run by sound bearings to the shore. Have a line attached to [the rubber boat] to retrieve it back on board.  Launched the rubber boat.
		06.35		Rubber boat is back.  On the shore, a man came with a light, but was apparently reassured by the people.  Meanwhile, the boat has been set higher than intended on the beach by the slight swell. It has turned to a heading of 235°, so roughly parallel to the shore.  Land cannot be seen.  Blew and tried to come free with E-motors.  No success.  The boat is too stuck.  Flooded again, so as not to get still higher on the beach.  Now try the same maneuver (blowing out with air and back AK) at the risk of being heard on land with the diesels.

			This maneuver is also unsuccessful.  However, succeeded in the following: turning the boat on course by backing on one diesel while going ahead on the other to a heading of 130° with the bow seaward.
		07.00	The fog is lighter.  Land comes in sight.  I lie about 200 meters from the shore close to the radio station at Amagansett. So despite the fog I am only about 1 nm to the east of the ordered landing point.  On the beach can be seen: a house, to its left a sort of tower (probably the beacon), still further to the left a bit behind the coast on a hill, the radio station with two masts.  But now it is gradually getting lively on land. Cars driving back and forth, but not stopping at the landing site.  A dog barks loudly and persistently.  At times, bursts of machine guns but from quite far.   For this purpose lively spotlights play at the radio station, and at three other points on the island.  However, they remain ineffective because visibility in fog is still about 600 meters.  The sector above is free down to about 30° all around the horizon.  Within it starry sky. The searchlights are all working above, but do not penetrate because of the ground fog.  I suspect that either our AK maneuver with the diesels was heard, and was taken for aircraft noise, or that something seemed not right to the man with the light, and he made a report to a watch.
			The boat lies quite high and dry with a list of about a 40°.  Low water is at 08:14 hours.  Then I must make a last attempt on the ebb flooding tide.   Meanwhile, pumped with compressed air.  The boat is prepared for demolition and the crew is ready to disembark.  Radio Message with report is ready to send.  There is only a slight hope.  Most grueling is the helpless feeling waiting for the accumulating water.  All tanks are pumped except for fuel bunkers.  Torpedoes are still in the boat.
		09.00	The water comes slowly - however in an hour it will be bright then I must be away or carry out demolition.   So now a final attempt.  Blew all ballast tanks with the last air, both diesels ahead 3 x AK with the E-motors switched in.
		09.10	T h e   b o a t   m a k e s   a    l i t t l e   p r o g r e s s    w i t h   e a c h   s w e l l   and is free of the bottom after about 4 tries!  Hurrah!!  Elation in the boat.  But now must get away while it is still dark!  On land we were apparently not noticed.  All the hustle and bustle is not taking place right on the coast, but in the background.
			The boat was made ready for diving.  Tank fillings established.  I still have 35 kg. of compressed air in the bottles. The visibility is better, about 4000 meters. That was the utmost and final time for us to get away,

		12.59		Surfaced.  Ran to the boats.  At the sinking location a great number of rolls or bales, apparently paper rolls.
		13.12		The Captain is taken aboard out of a boat.  The steamer is said to be "RIO TERCERO", ex "PORTUNSTELLA", with 4864 GRT.  In the Spring of 1940 was supposedly purchased by the Argentineans from the Italians.  According to the log it proceeds (the other cargo papers are sunk) since the beginning of the year between Buenos Aires and New York.
				On 20 January from Buenos Aires to New York
				"  22 February  "    New York to Boston
				"  1 March        "    Boston to New York
				"  21 March      "    New York to Buenos Aires
				"  20 May         "    Buenos Aires to New York
				"  22 June         "    New York to Buenos Aires.
				This steamer seems to me perfectly to drive in enemy service.  Cannot get much from the Captain's statement he can speak neither English nor French, and we are not Portuguese.  The steamer was loaded with 3000 tons of coal and piece goods, among them machine parts.  What he brought to New York cannot be determined.   Because the steamer has a cooling device according to Gröner, it probably brought meat to USA.
				Because the Captain was an Argentinean, I did not take him prisoner, instead let him climb into his boat again.
		13.55		Captain debarked.  Have just left the two boats, all waving enthusiastically, when an aircraft is spotted coming out of the haze at target angle 0° and low altitude.  Crash dive!

		00.58	The destroyer is in sight in the periscope.  Type like "CHURCHILL class" only with 3 smokestacks.  The after one is missing.  He proceeds at a slight distance from the steamer as U-boat screen.  It is painted quite dark, 2 masts, 1 smokestack.  The superstructure with the promenade deck goes from the level of the bridge all the way to the stern without interruption. Several decks above one another.  At least 6 lifeboats on each side.  The steamer makes a massive impression about 9000-10000 GRT.  The destroyer stops sometimes and runs various speed levels, depending on its course. At the yardarm a three-digit signal.  Hopefully only a course signal!
		01.20	Steamer lies very beautify abeam of me.  Bow left.  The destroyer proceeds with bow right target angle 60° on northerly course passing ahead of the steamer.  He has zigzagged to course 100°.  So I do not seem to be noticed yet.  I pay attention only to the destroyer, the steamer I have already.  I will give him a four-fan with a very small spread angle so that many torpedoes will hit so there is no need for a coup de grace.  The destroyer maintains its course. I am now positioned between him and the steamer.  The fan is ready!

			Destroyer bears 350°T, relative bearing 140°.  After the shot I take one quick look at him, he just Morsed to the steamer, can only read "ar".   Then went deep with hard rudder and AK.
		01.29		Hit after 1 minute 43 seconds = 1600 meters!  Initially a bright metallic click without detonation, a perfect pistol failure.  At short intervals three similar clicks with subsequent detonations.  Therefore all 4 torpedoes have hit.
		01.31		2 heavy dull explosions at the steamer.  Boiler explosions or munitions.
		01.32		Destroyer has stopped, goes towards.  Runs towards to throw.  However we are already at depth A +70 meters.
		01.34		9 depth charges at short intervals, over the boat, go somewhat deeper.
				7 further well placed depth charges, the boat settles rapidly from depth A +100 meters to A +120 meters.  The destroyer has stopped.  Awkward, because I must increase speed to get higher.  No water intake determined in the boat.
		00.37		Steamer sinks!  8 minutes after the hits!  Heavy rattle and crackle, typical sinking sounds.  Now the destroyer will probably be concerned with rescue work!
		00.41		Again 4 quite well placed depth charges.  The boat had been brought to depth A +90 meters, however on reducing speed immediately settled through quickly to depth A +120 meters.  Cause inexplicable.  The destroyer is still searching, stops sometimes.  Locating is heard. Ran off on general course 30°.

			well have been the maneuvers with backing down the propellers to bring the boat to a stop at the accident scene.  I have blown main ballast tank 4 twice during the persecution.  I have the impression that the destroyer initiated [his runs] off it.  But on the other hand it is possible that he thereby got the approximate location of the boat!

			CA 9678.  A check of the forward over deck canister shows that that it is completely crushed to a length of about 1 to 1.5 meters, to such a depth that presumably the torpedo is held with an iron grip.  Now the suddenly settling to great depth tonight is explained. The whole canister has been torn forward (probably at the first depth charges) has flooded and suddenly made the boat down by the bow and very heavy.  If the air bottle is damaged, then it is very probable it accounts for 1.9 cbm!

		02.32		Radio Message to B.d.U. (01.30 hours):  Convoy by sound bearings BD 9354.  Southerly zigzag.  No wind, Sea 0-1, low clouds, Vis. bad, 1030 mb, +19°C.    - Linder -
				Pursued on course 180°.
			The general course is only to the south.  The zigzags alternate between 130 and 210°.  I pursue on a due south course, even though the convoy bears 150°T, in order to prevent the convoy from breaking through to the west or southwest.  For I think it is still possible that the SE to S-course was only the dusk zigzag, and in reality the convoy proceeds on a SW course to Central or South America.  Then he could zigzag back again soon so I must stay to the west of it.  If he does not come, then he proceeds to Gibraltar and will be found again.
		03.12		BD 9349 upper-center.  Dived to listen, because nothing is seen.  Sound bearing in 205°T.  After a long time the bearing steadies and becomes fainter.  Therefore the convoy has come back to its old course 210°. Until surfacing it remains on the same bearing.

			Ran at highest speed, in the flat sea nearly at 16 knots.  Distance remains about the same.  The corvette does not let go, gradually comes closer.  Forces me damnably far from the convoy which passes quickly out of sight.  A vigorous zigzag can be expected when I am forced far enough away.

		18.52	Scholtz reports contact.  Now the third already!  I operate on the reports of the current contact keeper.  The corvette managed to force me about 40 nm behind the convoy.  It is questionable whether I can still approach before dark.  Cylinder 1 of the port diesel is leaking and making water, the diesel smokes heavily and is now limited in performance.  In the meantime Forster has gained contact and reported.   This means that there are now 4 boats besides me at the convoy, contact is thus ensured.  If I operate until tonight, I can return transit without supply.  If this is reported to B.d.U. he may decide on the advantage of a 5th contact holder against the disadvantages of the need to provide an outbounder to supply.
