A close-up view of the collapsed forecastle, taken from a ship's boat, of the destroyer HMS 'Mentor' (1914) while alongside the destroyer depot ship HMS 'Dido' (1896). The anchor chains have been secured around the riding bitts on the undamaged part of the forecastle to prevent the anchors from being lost. Part of the ship's boat can be seen in the foreground of the photograph.

The forward 18ft of the forecastle deck collapsed as a result of a torpedo explosion beneath the bow earlier that morning on 17 August when on a mine laying exercise off the Amrun Bank, 25 miles north of Heligoland. The ship was part of a larger group attacked by German torpedo boats. Mentor was able to steam back to Harwich. Aurora was in Harwich on 17 August.
