- PQ 13
Convoy PQ 13 departed Loch Ewe on 10 March 1942 and arrived at Murmansk, Soviet Union on 31 March having lost six ships to enemy action. A further two were sunk at Murmansk after the convoy's arrival. Tobruk was damaged by enemy bombing at Murmansk, repairs took about six months to complete. Crew members were joking later that the convoy departed on the 13th day of the month, the trip lasted 13 days, and Tobruk had the thirteenth position in the convoy.
- QP 14
Convoy QP 14 departed Murmansk on 13 September 1942 and arrived at Loch Ewe on 26 September, having lost four ships to enemy action. Tobruk was carrying a cargo of Apatite. She departed Murmansk on 8 September bound for Archangelsk, from where she joined the convoy.
- SL 178
Convoy SL 178 departed Freetown, Sierra Leone on 25 November 1944 and arrived at Liverpool on 15 December. Tobruk was on a voyage from Pepel to Barry, Glamorgan. She was carrying a cargo of iron ore and two passengers. On 9 December, a deceased seaman from Tobruk was buried at sea.
Postwar, Tobruk continued in Polish Government service until 1951 when she was sold to Polskie Linie Oceaniczne. In 1950 during a storm in the Bay of Biscay in order to prevent the ship from crashing into the local reefs the crew improvised a sail, saving the ship; this is the only known example of a modern bulk carrier using a sail. She served until 1967, and was scrapped at Gdynia in June 1968.
In popular culture
The wartime history of the ship has been portrayed in a novel S.S. Tobruk – w konwojach śmierci (SS Tobruk – in the convoys of death) by Jana Kazimierza Sawickiego.
