During fog, the Martha, a Stettin registered barque carrying 4000 barrels of refined petroleum from Philadelphia to Kaliningrad, mistook Dunnet Head for Stroma and became a total wreck on Dunnet Sands.  The crew were all saved.

It was later reported that she had hit Ness Rock, Dwarwick and completely broke up, with attempts being made to save as much of her cargo as possible. She was under the command of Captain Ehrenreich.
