THE LAST PATROL OF U-591
DEPARTURE
U-591 left
The escort out of St. Nazaire consisted of a mine destructor vessel and two patrol craft. All boats sped through the
MEETING WITH U-487.
Three days after leaving St. Nazaire, the boat commanded by Kapitänleutnant Dietrich was reported to have returned to her base due to engine trouble. The other four boats were said to have met a supply U-boat, U-487 under the command of Oberleutnant d.R.
PASSAGE TO OPERATIONAL AREA.
Continuing a few days longer on her original course of about 2400 T, during which time U-591 and U-598 kept in visual contact, U-591 changed course to about 2100 T when at 39º 00" N., 17º 00' 30'' W. Her speed after the meeting with U-487, was her most economical, as she was not going to be supplied again until the completion of her patrol activities on the Brazilian coast. In approximate position 28º 00" N., 250 W. course was changed to about 2000 T. The trip towards the bulge of
ATTACK BY AIRPLANE.
On 22 July 1943, U-591 sighted a patrolling aircraft and the order to dive was given immediately. Shortly thereafter explosions of bombs were heard, but except for the temporary failure of some light switches no damage was done. U-591 surfaced soon after, but again fond herself the target of a second attack, which she again eluded by crash diving.
(O.N.I. Note: These were probably the attacks delivered 12:28Z, 22 July 1943 at 40º 23' S., 33 17' W. and 13:58Z, 22 July 1943 at 40º 30' S., 33º 25' W. by planes of Bombing Squadron 107. Planes from the same squadron delivered another attack in about the same vicinity and about the same time on U-598, and it was probably during the holding-down tactics that U-591 was sighted and attacked.)
CHANGE IN COURSE -- ARRIVAL IN OPERATIONAL AREA.
After the attack, U-591 steered a southerly course, then changed to course 2700 T at about 080 S. She had arrived at her operational area and was ready to intercept any traffic that might be moving through the area assigned to her.
