On 18 January 1874, while travelling from Callao, Peru to Dublin, the 845-ton four–masted barque Minnehaha carrying guano was wrecked off Peninnis Head, St Mary's, Isles of Scilly. Her pilot mistook the St Agnes light for the Wolf Rock and thought they were passing between the Isles of Scilly and the Wolf. Shortly after she struck a rock off Peninnis Head (SV911094) and the vessel sunk at once with some of the crew being drowned in their berths. Those on deck climbed into the rigging, and as the tide rose the ship was driven closer to land, and some managed to climb onto the shore over the jibboom. The master, pilot and eight crew drowned.
