        Screen:  forward screen 2 PC boats, starboard forward patrol vessel type "EAGLE", behind it the same.  Port ahead a one-stack destroyer type "BLUE" with PC boat in echelon.  Aft screen not seen.  Painting partly white and partly spotted, strong machine gun armament.  Formation of the convoy:  double to triple line ahead, strongly staggered.  Take position between the right and middle column and intend to shoot at four or five overlapping steamers.  
    21.20 ED 9954 Shot from tube I:  target angle = 90°, target speed = 8 knots, range = xxxx meters  
      ED 9954 Shot from tube II:   target angle 40°, target speed 8 knots, range = 2000 meters.  
        Hit after 37 seconds running time on freighter type "ADRIA" amidships, second hit heard after 62 seconds, aimed at freighter 6000 GRT.  Sinking not observed, however, probable because the freighter was loaded.  
        At the moment of firing, the overlapping steamer had moved up to pure line abreast, so that only one ship was in shooting position, while all others behind were covered. Therefore the second shot fell on a steamer proceeding behind with target angle 40°.  Could not shoot further with the stern tubes because the boat had to dive under the column.  
        After both hits Asdic impulses start immediately.  Went at GF to depth A -30 meters (water depth 66 meters), ran off on course 300°.

    17.10 ED 9955 Spanish tanker "CAMPERO", course 270°.  Also easily recognized neutrality markings.  
    18.25 ED 9955 Convoy bearing 24°T, 8 freighters, 2 destroyers, 2 patrol vessels, course 90-110°, on the horizon.  A "Consolidated" observed through the periscope, flies straight line sweep on convoy course.  Initiated attack.  Both destroyers type "BLUE" proceed in echelon ahead of the convoy.  To the port side the same suspected.  Steamers proceed in staggered line abreast.  One destroyers is painted white, one spotted.  After outmaneuvering the destroyers I reach shooting position on a 7000 and a 6000 GRT freighter.  Am positioned within the right outer column.  
    19.15 ED 9952 Shot from tube I:  target speed = 8 knots, target angle = 92°, range = 1000 meters.  
        Shot from tube II:  target speed = 8 knots, target angle = 72°, range 1800 meters.  
        Piston from tube I does not run back after the shot, therefore the boat rises and is just caught at depth 10 meters with all men forward, GF, flooding the negative buoyancy tanks and both diving planes hard down.  Therefore hit effect not observed.  First hit heard after 114 seconds, accept that this freighter sunk (Lt. B-Service report).  Second hit was heard after 420 seconds.  There is no evidence showing whether this hit was carried out on the targeted ship or on another ship.  Both torpedoes depth 4 meters.  Ran off to the west 10 minutes at GF and depth A meters. Immediately after the shot impulses from 2 sound gears were heard.

    19.42 EF 7787 Smoke feather bearing 52°T.  Develops as a steamer with truncated masts, forward crow's nest, after mast significantly shortened not as high as smokestack.  On the bridge thin Radio Message mast.  Zigzags around 320°, 11 knots.  
    20.00 EF 7784 Maneuvered ahead, however cannot close for a day attack.  Because of the full moon the night will not get darker.  Therefore despite bad experience after maneuvering ahead decide on a submerged moon attack.  
    23.23   Dived to attack.

    00.20 EF 7715 Shot from tube IV:  target speed = 11 knots, target angle = 60°, range = 1500 meters, depth 2.5 meters, G 7a.  
        Running track is easily recognized, yet no hit. If it undershot is not exactly recognized in the moon illumination.  Suspect incorrect target angle estimation, waiting on target angle 90° now intend to shoot again with running target angle with the stern tube.  
    00.27 EF 7715 Shot from tube VI:  target speed = 11 knots, target angle = 110°, range = 1500 meters.  
        After 56 seconds running time a dull impact was herd in the entire boat, in listening gear propeller sound of the torpedo stops, however no effect observed at the target.  Steamer continues on at his normal RPM.  Estimated size 4000 GRT, perhaps less, because he is empty.  Depth 2.5 meters was too deep, suspect second torpedo rammed the keel of the steamer.  Pi-failure possible.

General Experience in the Operations Area:
Taking into account the previous patrol.
   
1.) As before heavy traffic.  Arrivals widely spaced, increasing in the full moon period, then outbound traffic almost completely stopped.
  Departing only convoys twice weekly up to 20 ships, course 310° and 90° at the same time.
   
2.) Defenses:
  Area covered by air has become larger. Increased use of faster land-based bombers with and without radar.  Sea defenses also in convoy still untrained.
   
3.)  Favorable attack locations:
  a)  By day on the 200-meter line on convoy course 310° off main harbor.
  b)  By day center of Passage.
  c)  If no traffic is observed by day off the 200-meter line with course 180° running for the main harbor.  At times quarter-hour all around sweeps are required so practically remain at periscope depth.

General Information:
The crew showed that they were completely up to the demands of the patrol.  Soldiers newly ordered on board settled in accordance with the circumstances and proved successful. The failure of the fresh water distillation equipment and the resulting protective switching with low output placed extreme demands on every man in the operations area.
   
                                   Duration:  78 days
                                   Total distance covered:  11627.7 nm.
