(1)

22 Nov 1943 (position 62.14, 5.14)
HNoMS Ula (Lt. S. Valvatne) torpedoed and sank the Norwegian merchant Arcturus (1681 GRT, built 1892, offsite link) north-west of Stadlandet in the Vanylsgapet, about 2.5 nautical miles north of Honningsvaeg, Norway in position 62°14'N, 05°09'E.

The Arcturus was already damaged, on fire and under tow after an attack by British aircraft earlier in the day. The Arcturus was towed by the auxiliary patrol vessel V 5101 and escorted by the auxilirary submarine chaser UJ 1709. Ula fired one torpedo at a whale catcher and one torpedo at the Arcturus. Both torpedoes however hit the Arcturus. The two escort vessels joined by the tug Furu and the minesweeper M 5615 searched for survivors and twenty-one men were rescued. Ula escaped without any counterattack.

(All times are zone -1)
1355 hours - Heard HE bearing 255°.

1358 hours - Sighted funnels and masts of three ships bearing 257°. Enemy course was approximately 180°. Smoke and flames were seen on the after part of the last and largest ship.

1409 hours - The vessels were now seen to be a laden merchant vessel of 3500 tons, one armed whale catcher of 800 tons and one armed trawler or tug. The merchant vessel had a small fire in no.4 hold.

1414 hours - Fired the first torpedo at the whalecatcher from 700 yards. A hit was heard.

1415 hours - Fired a second torpedo but now aimed at the merchant vessel. This torpedo also hit. Ula meanwhile had gone deep.

1428 hours - Ula hit bottom. She quickly broke free but had lost depth control.

1430 hours - Ula broke surface. Only the smaller escort or tug was seen.

1436 hours - Went to 100 feet. No counter attack developed. (1)

24 Nov 1943 (position 62.27, 6.04)
HNoMS Ula (Lt. S. Valvatne) attacked a convoy made up of three merchant vessels heading south escorted by two escorts. Ula fires two torpedoes but these missed their intended target (a merchant vessel of 8000 tons) and hit land instead. These were tankers Altengamme and Amrum, the steamer Trotsburg escorted by K 2 and V 5304. Shortly after this attack Ula spotted a merchant vessel heading north escorted by a M-class minesweeper, Ula fired two torpedoes at the merchant, one of these hit the German merchant Eisstrom (928 GRT, former Dutch Marietje Bohmer) off Alesund, Norway in position 62°27'N, 06°04'E. She was escorted by minesweeper M 407 and beached near Eltrenes. The attack was unobserved and she was believed to have been mined at that time.

(All times are zone -1)
1336 hours - Sighted smoke bearing 096° Probably a convoy coming south through the lead of Alesund.

1420 hours - Sighted mastheads bearing 118°. Range approximately 9000 yards. HE was also reported from that direction.

1425 hours - Sighted three merchant vessels bearing 115°. The last one was seen to be a large merchant vessel of about 8000 tons. This ship was choses as the target. This would be a very long range attack as we were unable to close the range.

1430 hours - In position 62°25'N, 06°02'E fired two torpedoes from a range of 10000 yards. It was intended to fire four torpedoes but Ula dipped on firing. Two torpedo explosions were heard almost 9 minutes after firing. This were thought to be the torpedoes hitting the land beyond the target. It appeared the range had been overestimated.

-------------------------------------------------------

1455 hours - Sighted a laden merchant vessel of 4500 tons escorted by an M-class minesweeper bearing 125°. Range was approximately 8000 yards. Started attack.

1508 hours - In position 62°27'N, 06°04'E fired two torpedoes from 7000 yards. Remained at periscope depth to see the result of the attack.
