On 12 November, V/s
Þór encountered the trawler
Hackness which had not stowed its nets legally.
Hackness did not stop until
Þór had fired two blanks and one live shell off its bow. Once again, HMS
Russell came to the rescue and its
shipmaster ordered the Icelandic
captain to leave the trawler alone as it was not within the 4 nm (7.4 km) limit recognized by the British government.
Þór's captain, Eiríkur Kristófersson, protested that he would not do so, and ordered his men to approach the trawler with the gun manned. In response, the
Russel threatened to sink the Icelandic boat if it so much as fired one shot at the
Hackness. More British ships then arrived and the
Hackness escaped.
