At 20.26 hours on 20 Jan, 1940, the Miranda (Master Asser Hiorth) was hit by one G7e torpedo from U-57 about 30 miles northwest of Peterhead. The U-boat had spotted a group of five steamers and an escort and tried to attack the leading ship, but the distance was too short so they fired a torpedo with a magnetic fuze at the second ship. The explosion broke the keel of Miranda and caused her to sink within five minutes. Three survivors were picked up the next day by the British armed boarding vessel HMS Discovery II and taken to Kirkwall.
