Note:  The positions in the table above and in the Google Earth patrol summary are derived from the KTB and in many cases do not match those set forth in authoritative references such as Jürgen Rohwer, Axis Submarine Successes of World War Two or the Uboat.net website.  The goal here is to present the picture relative to the U-boat and not the absolute position that the ship was attacked or sank.

In the case it is hopeless for Höltring to attempt the return passage, U-604 is to be sunk.  For this following orders:

 
       

1)  Höltring and Maus are to rendezvous in FK 3955.  Then are to proceed together to FL 1255.  There Höltring is to hand over all fuel to Maus, as well as half of the provisions.  As much as space permits, important equipment is also to be handed over. 

 
       

2)  Tonight Emmermann is to report by short signal arrival in the latter square.  There the remaining provisions are to be taken over and the crew of Höltring is to be shared equally between the two boats.  Subsequently U-604 is to be sunk.  After scuttling Maus is to report 'Yes' and both boats are to return to the base independently.

 
        3)  Further distribution of Höltring's crew on other boats is intended.  All positions marine squares.

    20.04 FD 9551

Aircraft at 210°, diving from high altitude out of the haze, flying at low altitude, flying height 40 - 50 meters, approaching the two connected boats from portside abeam.

 
        Six depth charges, four on portside, one between the boats and one starboard of U-604.  Opened fire with 20 mm and machine guns.  
        Defended with all machine guns, hit possible.  
       

Very strong shocks, both boats disappear in the fountains of water.  Bomb impacts at 15 and 20 meters abeam on both sides of the boat.  Diesel engines full speed, lines and hose connections cut.

 
       

Matr.Ob.Gefr. Schiemann killed in action by heart and neck shots while removing the muzzle plug of the 105 mm deck gun on the forecastle.

 
    20.06  

Second approach-run steep from portside ahead.  Boat is increasing speed.  Altitude 20 meters, two depth charges, one of them detonates 5 meters away behind the stern, at a depth of about 20 meters.  Strafing fire.  Boat makes a leap forward.

 
       

Matr.Ob.Gefr. Wagner seriously wounded by a shot in the chest and a grazing shot in the arm, Matr.Ob.Gefr. Meiβner slightly wounded at the eye by splinters.

 
       

Several breakdowns.  Rudder jammed to port at 10°.

 
       

All boats are zigzagging at full speed one around the other giving protection to each other.

 
       

In doing so, I'm continuously in ramming position with U-185, which has not the slightest notion of my rudder failure.

 
        Both machineguns out of action.  The LI reports the boat ready for diving.  
    20.15  

Crash dived when the aircraft apparently has no bombs left and is shadowing us, given the condition of the boat I can't give assistance to Höltring.

 
       

Went to A +20 meters.

 
        Damages repaired.  Gyrocompass is still out of action.  Magnetic compass temporally out of action.  Several tanks cracked.
