			Hit behind the bridge, 2nd hit under the stern, steamer stopped and settled astern about 3-4 meters deeper.  During the run of the torpedoes boat broached with the conning tower out briefly.  The result was heavy artillery fire from 2 cannons and several anti-aircraft weapons. Through attack periscope extended just above top edge of the conning tower, I saw water columns rising next to the boat.  Apart from a short sharp bang, there was no effect on the boat.  After catching the boat at depth 15 meters I ran behind the steamer at GF.  When again extend the periscope after running for 10 minutes, the steamer is still shooting. Close observation gave the impression of wild fear shooting in all directions.  Because the position of the steamer did not change over 3/4 hour,
		07.15	Coup de grâce aimed at the bridge, hit under the after mast.  Impact point shift unexplained because 42 minutes after the first hit by listening gear and bearing of the ship it could not have been underway.  The effect of this T 3 was disappointing to me.  My suspicion of torpedo nets proves unfounded after a careful examination.  Steamer crew shoots continuously randomly in all directions.  Ran around the steamer.  Position was unchanged, heavy artillery fire.  An occupied lifeboat hangs in the davits.

		16.00	MF 6879
		16.12	MF 6879	Shortly after sunset the convoy is in sight bearing 284°T exactly as plotted.
			Because the twilight is advancing quickly, I ran to the convoy at GF.  Course 35°, speed 10 knots is confirmed exactly.  To be certain we match the speed once more exactly.  10 knots.  The weather conditions are like every evening.  Mirror flat sea, phosphorescence which we do not know in such strength from home waters.  Heavy haze by which the horizon is so milky that the transition from water to air is barely noticeable.  These unique lighting conditions lead initially to an incorrect estimate.  Therefore broke off the approach.  Matched speed once again for a new attack from ahead.  This time the distance is correct.  The tried and tested binoculars measurement gives us an accurate range.
		20.00	MF 6855
			SW 1, Sea 0-1, 1/4 overcast, strong haze, milky horizon, Vis. 1-2 nm

			Wind calm, flat sea, heavy haze, extraordinarily strong phosphorescence
				Bearing            = 296°T, 297°T, 295°T, 288°T
				Target angle     = 81°, 82.5°, 79.5°, 72.5°

				Lead angle        = 19°
				Target speed     = 10 knots
				Range               = 1500 meters
			Ran with the convoy on course 35° to observe the hit effects.  After 8 and 9.5 and 10 minutes 6 detonations.  With the reliable range from the binoculars it seems to me the running time is too great even for the vessels of the further off columns.
			Report from the Second Watch Officer of a destroyer ahead to port at a sharp target angle.  Turned away hard and broke through behind the convoy.  Searched the shooting location, except for 2 large oil fields nothing found.  Because necessary diesel repairs make further pursuit impossible, I remained at the location and have all torpedoes on board checked.  Rotating through all values does not yield an error source.  Course and speed were checked by day and night, as well as the far off set maneuver-ahead which matched exactly to the minute.  Believe the 6 detonations were end of run detonations.

				Reception by the Befehlshaber der Unterseeboote for the Indian Ocean.
			Summary:  The patrol made demands of the entire crew which went far beyond the usual.  Especially remaining submerged with the heat, stifling air in the Gulf of Oman (highest temperature in the diesel room after convoy hunt 73°C) required hard and tough endurance.  Due to the high temperature diesel had to bear such stress that frequent failures occurred and with respect to the long return transit, operational limitations were necessary.  The unexplained behavior and detonation of all the Etos at the end of the running track - according to the situation of the approaches - reduced certain chances for success to a minimum.  The frequent need to work at to the limit of performance, which inevitably took place without regard to health requirements, and the excellent attitude of the crew, despite the hardships and disappointments make the lack of successes particularly hard.  Based on the experience gained, entering Penang briefly to overhaul the torpedoes and machinery before the transit into the area of operation promises better operational conditions.  An operation in this form allows for the possibility of acclimatizing the crew and exchanging experiences with the Japanese Submarine Operations Division for boats coming from home.
