According to Charles Hocking [35]:

... The attack took place at daybreak on August 4th 1918, two torpedoes striking the vessel in quick succession. The first exploded in No. 2 hold and the second in No. 3 hold carrying away the stokehold bulkhead, and causing a tremendous inrush of water which sank the Clan MacNab in two and a half minutes. Capt. Smith, six other officers and 16 native crew lost their lives. The survivors were picked up by the Belgian steamship Kasbek, also in convoy, despite the heavy sea. They were then transferred to the destoyer Owl and landed at Milford Haven. At a later date the British Government presented Capt. Sytor of the Kasbek with a silver cup and he was also the recipient of a gift from the Clan Line.
