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.

 

The first section of this KTB uses the depth notation "depth T = xx meters"  Under this scheme, the actual depth was twice the depth given after T = so for example, if the KTB entry read "depth T = 50 meters, the actual depth was 100 meters.  This was intended to hide the actual depth for security purposes. This notation was used from about January 1940 to December 1941.  In these KTBs, depths written without using "T =", for example "dived to depth 35 meters" were not so disguised.

				On 16 February the first steamer would be at the level of Macolla at about 10.00 hours, because high water Maracaibo is so late.  Patrolling Venezuelan gun boat must have noticed events at Aruba.  After my first torpedoing the lights were extinguished and the other tankers held back, because after the first 3 nothing more came.

				The ships position was taken accurately by the evening navigation fix at 00.18 hours and by bearings from Cabo de la Vela at 03.25 hours.  At 06.53 the 20-meter line lay at 06.53 11 nm from the ship's position (12° 05.3'N, 72° 34.8W).  Because from the 20-meter line to the 80-meter line at 7 knots cannot have been crossed at this location in 15 minutes, there must be a hitherto unknown shoal at this location.

				Hit at the bridge and aft 30 meters.  Tanker burns.  Two tanks were discharged immediately by the detonation.  The bridge burns out, however does not settle deeper.  Boats were launched.  Cannot use the cannon due to the Sea State.  The entire sea is full of crude oil.

	I.) The views of the Ob.d.M. on page 27/28.   The Operations Order for the first operation of U-boats in the West Indies area envisaged the mission as a surprise simultaneous attack on traffic immediately off the West Indies islands.  The core of the mission lay in the surprise and the simultaneous appearance off the main points of Aruba and Curacao.  U-502 was assigned among other boats for this mission.  By keyword, 16 February was ordered for the first simultaneous attack of all boats.  The time prior to permission to attack was to be used by the boats to observe navigation and traffic conditions in the attack area.   Therefore on 14 February U-502 was not to attack the tankers sighted off Aruba.     II.) Ob.d.M. Chef 1./Skl. was informed of both the facts and explaination.     III.) On the K.T.B. U-502 from 10 November to 16 March   =  1./Skl. 8261/42 gK.
