Repairs at Sheerness lasted until 28 August and she was converted back into a minelayer at Immingham from 28–31 August as she was transferred back to the 20th Destroyer Flotilla. That night, she sailed with "Intrepid", "Icarus", "Esk" and "Express" to lay a minefield off the Dutch coast, north of Texel. "Express" hit a mine in a newly-laid German field that night and had her bow blown off. "Ivanhoe" closed to assist her and struck another mine shortly afterwards. The explosion knocked out her power for several hours, but the ship was able to raise steam by 01:45 on 1 September. She reached a speed of while steaming backwards to lessen the stress on her damaged bow. However, about 04:00, either her propellers fell off or her propeller shafts fractured, and she lost all speed. Around 08:00, four motor torpedo boats arrived; three of these loaded all but 37 men of the ship's crew while the fourth stayed with the destroyer to recover the remaining crewmen. "Ivanhoe" continued to take on water and started to list. Early in the afternoon, she lost all power to her pumps and the captain ordered the ship abandoned after opening her valves to speed her sinking. Shortly afterwards, "Ivanhoe" was discovered and damaged by a German aircraft, but still did not sink. She had to be scuttled by a torpedo fired by the destroyer later in the afternoon. The ship quickly sank afterwards at position .
