				Main ballast tank 1 flooded.  Boat lies before the seas 3° down by the stern.
				Mech.Ob.Mt. overboard with Tauchretter to check the outer tube door of torpedo tube 2.
				Findings:
				1)  Rim of the tube opening is evenly smooth everywhere.
				2)  Rubber ring of the outer tube door is likewise undamaged.
				3)  Outer tube door goes completely open, fairing flap goes completely back so that the torpedo could be ejected freely.
				4)  On closing the outer tube door does not seat firmly on tube mouth and the fairing flap does not nestle itself completely into the hull.
				Assumption:  Presumably, the linkage has been twisted because when the door was first opened on 25 April the linkage was very stiff at first.
				Measures:
				1)  Linkage inside the boat was uncoupled.  Crank was set back half of a rotation. The linkage was turned one half turn closed. The outer tube door is still leaking. The crank was then put back into original starting position to ensure that in any case the tube door could be fully opened.
				2)  Because the T V loaded in torpedo tube 2 is likely to be inoperable after several days without maintenance in the flooded tube, the Fat II loaded in tube VI is replaced [with a T V].

		18.56	EU 8881	Destroyer mast in sight bearing 230°T.

		18.58	EU 8888	Smoke feather bearing 271°T about 16 nm away.
				Destroyer mast bearing 335°T about 10 nm away.
				Crash dive!
				New enemy came out quickly and was made out in the periscope as an escort boat, therefore no destroyer.
				Enemy now has bow right target angle 10°.  Silhouette:  "ATHERSTONE" class.  Very prominent signal halyard - Fu.M.O. aerial.
				Steers with bow left and right about 5 nm away from us.
				Escort boat seems to listen, stopping and starting again with the propellers herad clearly in our listeng gear.  T V in tube 2 is prepared for W.S. [far] shot.  However the enemy does not come closer than 4-5 nm and suddenly goes out of sight at high speed bearing 70T, target angle right 160°, course 90°.
		20.04
				Assume that the escort boat wanted to chase after the steamer steering 310° but was distracted by the sight of our diesel exhaust cloud.

		23.05.44	Southwest of Freetown
		05.02		Pursuit is hopeless in this visibility without Fu.M.O and Fliege.
				Probably, I came across a search group of two destroyers or escort boats who work with the support of air location [radar]. No "Asdic" or propeller noises merchant steamers were heard. The result of the sound bearings show that the Balkon sound gear does not detect vessels at sharp target angles until very late.

				Summary of the period in the operations area off Sierra Leone, Liberia and Ivory Coast from 21 April to 23 May 44.
				A)  Sierra Leone Freetown:
				During several successive moon-dark nights monitored the approach sector from the SW to within the 200 meter line of the Saint Ann Shoals.
				No traffic appeared, air and sea defenses were not met.
				No detection.
				By this the approach route leading from ET 5386 set forth in Standing Kriegsmarine Order 481 B XI 2 seems lightly traveled.
				Four weeks later, also in dark night with unfavorable visibility

		23.05.44	Off Freetown	with unfavorable visibility,
				the boat in ET 6153, just off the 200 meter line was overrun by two patrol vessels and detected.  Suspect patrol vessels were working together with air location, then boat was twice forced to submerge for Naxos detections (Rotterdam gear).
				B)  Liberia - Monrovia:
				Within and at the 200 meter line no traffic, no air or sea reconnaissance.  In ET 6610 neutral traffic was observed in direction 125° and 310°.  A total of three ships.
				Monrovia harbor was seen at a distance of 2 nm from the lighthouse.
				A "Lerwik" flew over Monrovia harbor on a coastal course.
				The roadsteads off "Harper" "Rocktown" and "Half Cavalla" were examined.  Except for fishing boats nothing was observed.
				C)  Ivory Coast:
				Also here various harbors were examined.  "Grand Bassam" "Port Bouët" "Fresko" "Grand Lahu" and "Tabou" offered no traffic
				In EU 8618 a new Naxos detection was noted once, presumably coming from a land unit.
				In EU 9212 normal Wanze detection on 169 cm.  The route between "Cape Palmas" - "Cape Three Points" was repeated and raked on the basis of the most likely enemy courses.
				D)  Set off from the coast up to 250 nm southwest of Cape Palmas:
				On 10 May in EU 8889 hunted a fast freighter by day course 310°.  In EU 8881 forced to submerged by "ATHERSTONE" escort boat coming from the north.  Suspect that here, 100 nm from Cape Palmas, is a escort intake point for fast independents.  In this sea area repeated detections and in the periscope several vessels sighted.  (One Lockheed "Hudson" one "Wellington" and two "Lerwiks")
