(0) Near Kasos Strait.
|At 1420 hours, smokes were sighted on the horizon. At 1450 hours, the upper works of a destroyer could be discerned at 15,000 metres. Later, the convoy could be seen, consisting of eight merchant ships, escorted by a light cruiser of the CERES or CALEDON class and two destroyers, on a NNW course. This was most likely convoy AN.19 escorted by the antiaircraft cruiser HMS Coventry and the Greek destroyers Spetsai and Hydra. |
Ondina vainly attempted to close, but gave up at 1735 hours as the distance was now 10 miles and she just made an enemy report.

|25 Apr 1941||1956|
(0) Near Cape Plaka (or near Cape Kaso).
|Several hydrophone effects had been heard since 1518 hours. |
At 1956 hours, Ondina had just surfaced when a large MTB was sighted at a distance of 500 metres. The submarine dived immediately, but the hatch could not be properly closed until a rating managed to unblock it and the submarine dived to 85 meters.
Depth-charges exploded but high above the submarine. Other patterns of depth charges followed at 2023, 2024 and 2025 and a last one at 2320 hours, which caused some damage forcing the submarine to 130 meters. H.E. continued to be heard and oxygen was running out.
At 1830 hours on 26th April, Ondina finally surfaced with the gun crews at the ready, but fortunately the horizon was clear of enemy vessels. The damage inflicted by the depth-charging and S.T.V. Galletti who had been very sick with high fever since 22nd April forced the abandonment of the patrol.

|6.||Ondina (ON)||13 Jun 1941||1643||Leros||27 Jun 1941||1304||Leros||1066||Patrolled between Alexandretta and Cape Andreas, Cyprus.|
|23 Jun 1941||2130||36° 08'N, 34° 44'E||At about 2000 hours, a vessel was sighted coming from the direction of Mersin (Turkey). At 2100 hours, Ondina began closing for the attack. The vessel was flying the Turkish flag and estimated at about 9,000 GRT.|
At 2130 hours, two torpedoes (533mm) were fired from the bow tubes at a range of 1,000 metres, They missed ahead.
This was the Turkish Refah (3,512 GRT, built 1901) on her way from Mersin to Alexandria (or Port Said) carrying Turkish naval officers destined to England for a submarine course.
Ondina turned sharply to port to revert course and fired a stern torpedo (533mm) from 1,000 metres. It squarely hit the vessel, followed 30 or 40 seconds later by a secondary explosion, believed to be from boilers exploding. She sank at 2200 hours.
The sinking could have proven an embarrassment to the Italian government, as Turkey was sought as an ally in the war against the Soviet Union. The Italians were ready to deny their involvement. Dal Pozzo had refrained from using his gun so as not to reveal that the vessel had been sunk by a submarine and this was justified as British authorities attributed the sinking to a mine. Captain Christopher Michael Cadogan of SOE was travelling on this ship (he was drowned).
Of some 200 passengers and crew, 168 were missing and 32 survived.

|8.||Ondina (ON)||8 Feb 1942||1430||Brindisi||18 Feb 1942||1630||Brindisi||1114||Patrolled off Cyrenaica, within 8 miles on the meridian from 34°30'N, 21°10'E, on a patrol line with Sirena. On the evening of 13th February, she was shifted 20 miles to the south then back to her original position. Due to defects to her diesels, she had to interrupt her patrol.|
|10 Feb 1942||1156-1235||At 1156 hours, a derelict mine was sighted. It was an occasion for some firing exercises with light machine guns and rifles. It finally was exploded from a distance of 250 metres at 1235 hours.|
|13 Feb 1942||2058||At 2058 hours, a submarine was sighted on an opposite course. Ondina had just been ordered to change her patrol position to the south. Ondina turned away.|
|14 Feb 1942||0854||34° 11'N, 21° 10'E||At 0648 hours, hydrophones noises were heard but, when the submarine rose to periscope depth, nothing could be seen.|
At 0854 hours, explosions were heard, believed to be from aircraft bombs. Ondina went down deep. At 1115 hours, another loud explosion occurred, but this time the hydrophones detected an antisubmarine vessel. More depth-charges followed at 1355, 1720 and 1830 hours.
|14 Feb 1942||2242||At 2242 hours, information was received of a large convoy on easterly course.|
Ondina steered 231° to intercept. Hydrophone effects were heard without sighting anything and defects finally forced her to return home.
