37° 06'N, 15° 50'EAt 1230 hours, a torpedo track was sighted and missed Wolframio by 50 metres on the starboard side. The Italian submarine fired three rounds in the presumed direction of the enemy submarine for intimidation purposes.

The attack was made by the British submarine HMS Una (Lieutenant C.P. Norman). The Italian submarine had been sighted at 1215 hours, steering 231° at 9 knots. Due to overstrain and fatigue, Norman had forgotten to order the reload of the torpedo tubes after an attack on the light cruiser Emanuele Filiberto Duca D'Aosta earlier in the day. A single torpedo was reloaded under 8 minutes and fired at 1221 hours at a range of 600-800 yards. It was believed to have missed the target by only 10-15 feet.

(0) Off Bone.
At 1615 hours, a submarine, believed to be Italian, was observed proceeding on the surface on a southerly course and later submerged. Hydrophone effect was heard but nothing could observed through the periscope but depth charges explosions were heard close. Wolframio was later ordered to go to the Bay of Djidjelli, but could not comply as it was 110 miles away and the submarine had not had an opportunity to fully.charge her batteries Finally, at 1330 hours on the 15th, she was ordered to check the Bay of Bougie but sighted nothing.
  20 Nov 19420645
(0) Near Point C of Cagliari.
At 0645 hours, the submarine Giada was encountered and exchanged recognition signals.

  7 Dec 19422316The submarine was informed about a German aircraft shot down and at 2316 hours arrived in the presumed area and began searching.

At 0417 hours on the 8th, nothing could be found and Wolframio returned to her patrol area.
  8 Dec 1942065837° 21'N, 8° 24'EAt 0632 hours, a vessel was detected with the hydrophones.

At 0658 hours, Wolframio came to periscope depth and observed an enemy destroyer. The forward tubes were not yet ready to fire, when the destroyer passed some 500 metres from the submarine. At 0730 hours, the target disappeared over the horizon.
  10 Dec 19422320At 2320 hours, an aircraft dropped three flares over the submarine. Wolframio dived.
  11 Dec 1942052737° 31'N, 6° 56'EAt 0527 hours, a destroyer was sighted in poor visibility. It moved away and Woframio submerged at 0551 hours. The destroyer returned at 0658 hours and was joined later by a second vessel. The submarine was depth-charged ineffectively until 0952 hours and escaped by going deep.
  11 Dec 1942201537° 20'N, 6° 34'EAt 2015 hours, a destroyer, five corvettes and a small patrol vessel were sighted at a distance of 3-4,000 metres. Wolframio submerged to attack, but lost contact with her hydrophones.
  13 Dec 1942172537° 51'N, 6° 56'EAt 1725 hours, four destroyers were sighted at a distance of 2,000 metres. Wolframio turned away to fire her stern torpedoes, but the distance had closed rapidly and the track angle did not permit a good shot. The submarine was forced to submerge.

All the merchant ships were towing a balloon with about 100 metres of cable. Wolframio made a submerged approach but gave up because the noises of the MTBs confused the hydrophone operator.
  18 Feb 1943101537° 03'N, 5° 57'EAt 1015 hours, two steamers escorted by two MTBs, were sighted at a distance of 5-6,000 metres on easterly course. Wolframio dived again to 50 meters, but could not regain contact.
