        dived.  Only slight damage, repaired.  
        Approach was so lightening fast that the 2 cm antiaircraft weapons could not be brought to bear, ordered rudder position did not have any effect due to the sluggishness of the boat.  
        Aircraft must have sighted the boat in the full moon track.  Detection was not noted.

        At 15.14 hours Metz gave the report concerning gear taken over.  
        Supply in these heavy seas and swell is very difficult.  The light oiling gear, only hoses, proves itself very well.  The transfer of provisions is the most difficult, the connection was cut at 19.45 hours and was not established again until 21.25 hours.  
        Although none of the boats needs provisions, they had to be delivered to keep the boat in balance.
