		20.00	AM 6545	The defense activity was very strong through the entire day. At least 15 vessels hunted in the narrows of the North Channel and threw depth charges continuously.
		21.40		Raised the boat from the bottom.
		21.50		Surfaced.
			After the 3-4 remaining hunting groups were some distance away, I decided to move off under the protection of the coast of the Gallowy Peninsula and charge the battery.  I considered this more promising than snorkeling without a periscope, because there was still vigorous hunting in the entire North Channel.
		21.55		Boat was overflown by aircraft (altitude 200 meters).  Did not dive, was not shot, no bomb throwing.
		22.00		Reached the coast at Cape Corsewall, drove along it to the south at a distance of 1 nm.  By this hoped to be safe from locating.  Own Fu.M.O. is out of service.  Rundipol antenna on the bridge is out of service.  Multiple times aircraft were close by.  Several U-boat hunting group passed on northerly course at a distance of 3-4 nm, throwing depth charges.  Remained unnoticed.

		01.20		Irish coast in sight.  Small convoy with several escort in 330°R = 240°T, bow right, target angle 50-80°.
				Ran towards.  At range = 80000 meters a convoy escort vessel turned towards the boat.  At the same moment

				From the depth charges on the morning of 21 February the following damage resulted:
				1.  Air search periscope out of service.  It is fully flooded at the periscope head.
				2.  Fixed periscope is limitedly usable.  The view is fragmented and blurred due to damage to the lens below the ocular prism.
				3.  Speed measurement system out of service.  Axel in the display gear drive is broken.
				4.  Fu.M.O. out of service.  Antenna installation can no longer be extended.
				5.  Light projection compass out of service.  Irregular deviations up to 70°.
				6.  Glass damage.
				7.  Manometer piping for the depth gages leak.
				8.  High pressure air piping to the foreship leaks.
				9.  Both Ampere hour meters out of service.
				10.  Port engine telegraph out of service.
				11.  Sheet metal damage.
				Damage 1 to 6 could not be repaired.
				Damage 7 to 11 were repaired.
			With this damage further operation in the North Channel is pointless.  I decide to go into the southern part of the Irish Sea and will attempt to shoot by sound bearings at the traffic concentration points there.

				The sound conditions are so bad when lying on the bottom, that calculating by the quick shift of the bearing (in 5 minutes about 90°) the vessel was first heard at range = 2000 meters with Volume 0-1.  This is not enough time to get from the bottom to periscope depth or shooting depth.
			Suspect as cause, that the Bodenkanzel [bottom pulpit - housing for GHG hydrophones protruding from the keel forward] was over spilled by sand.  Therefore after the battery is full again, intend not to lie on the bottom with opposing current.
		16.00	AM 9512
				For two days in the over deck a steady growing stronger rattle and banging of metal parts is heard.  One of these sounds comes from the rod antenna, that at KF rattles in the driving flow.  The rubber pad seems to be worn through.  Ran towards the Irish coast to surface and correct the sounds.

				Experiences:
				As outbound route, cruising directly under the Shetlands and Hebrides seems best along the 100 meter line because no surveillance was determined there.  I had the impression that the Englander feels very safe there.
				On the outbound transit, it was shown that the snorkel training obtained in the homeland does not meet the requirements of practice.  Each boat should have to snorkel before the patrol at least once 1-2 days uninterrupted, preferably during tactical or pre-tactical exercises.  Based on my own experience, I think it is possible that some boats that did not return from patrol had less luck with the same difficulties and failed.
				General:
				The crew consisted of 80% freshly trained U-boat men.  The remainder also had no experience with regard to snorkeling activities.  Nevertheless, the combination fulfilled all the tasks assigned to it and overcome particular difficulties.  Also with the depth charge pursuit the behavior of the crew was good.  Especially noteworthy was the performance of the machinist personnel, who in tireless work, eliminated the constantly occurring malfunctions in the propulsion installation, as far as possible with on-board resources.  The boat operation was handled according to
