Final remarks:  During the whole operation no position-finding activity of enemy aircraft observed with certainty.  Seems to indicate smallest employment of enemy night aircraft in this area.
        Navigation made difficult by following conditions:  Position lies on border of blind spot of "Elektra-Sonne".  Taking of bearing of "Sonne" inexact because of close proximity (broad minimum).  Depth given in the charts at our disposal very different and inexact.  Furthermore, as depth contours, in general, are running east-west just like the current, drifting cannot be detected by soundings.  Current strength and direction depends almost without exception on wind and differences of density (not tides!), cannot be calculated in advance.  Especially as north of outgoing current which follows the deep channel.  By lying on the bottom with a 5 trim forward the direction of the current in the deepest water layers could be observed and data for the total current direction be gained.  Radio beacon "Lister" gave good position lines.  Simultaneous transmission of the Danish radio beacons (Hanstholm, Skager Rev, Hirsholm) would have been of advantage.

0530   AC 8826   Discovered that the continuous increase in the boat's weight is caused by air escape from no. 3 ballast tank.  This also explains sticking of pursuers to bubble track.  Emergency flaps are closed.  Hydrophone effects becoming weaker, depth charges more distant.

  Final remarks:  
  boat's first operation in enemy waters, at the same time first Schnorkel operation.  Ship's company has gained full confidence in the seaworthiness of the boat and has recognized the great possibilities of the Schnorkel.  
     
  The best time for the use of the Schnorkel was found to be during the hours of dusk between 2200 and 0200.  At this tim the highest charging effect was used (1 Diesel charging only, 350-400 R.P.M. driving Diesel with charger attached 300 R.P.M.)  accepting a deterioration of observation caused by higher bow wave.  Average time of use of Schnorkel 3 hours.  
     
  Navigation by shore bearings and soundings.  Sonne 20 was heard during the outward and return voyages only, not in the operational area over the round dipole.  
     
  W/T reception over round dipole possible up to sea 4 when using Schnorkel, above that, fragments only are received as dipole is covered with water too frequently.  
     
  The absence of emergency breathing tubes was very disadvantageous when being pursued with depth charges on the 29 - 30.4. but it was shown that with some will power and a good physical constitution even high percentages of CO2 can be endured.
