A starboard quarter view of the general cargo ship King Cadwallon (1900) capsized with her starboard bulwarks under water on Hard Lewis Rocks, east of St Martin's Island, Scilly. A rowing boat with the number '22' on the port bow is just off the starboard side with one man standing up rowing and two others looking at the wreck. A couple of other small rowing boats are of the starboard bow.

This is very similar to P50787.

King Cadwallon was on voyage from Cardiff to Naples with a cargo of coal in foggy conditions when she struck the rocks off St Martin's at about 5am on 22 July 1906. On striking the head canted to starboard and the forehold filled with water within 10 minutes. The crew abandoned ship and awaited rescue. The ship became a total loss after slipping back into deeper water.
