'Invercauld' in Heavy Weather, What indication caused the journalist to conclude that the castaways were slowly starving so turned to cannibalism to stay alive? The ship had struck on the ironbound coast of the Auckland Islands”
The English mail which arrived in October, 1865, brought the news of the second wreck, and of the strange fact that a second party of men had for one year and 12 days been on the island with Capt. Musgrave and his party - each unknowing of the presence of the other, although each had done what it could to explore, on an island the whole area of which is roughly calculated to be not much more than 100,000 acres.

A gallant ship bailing from the Land o' Cakes, the Invercauld, commanded by a stout old Scotchman, Captain Dalgarno, sailed from Port Phillip, en route for London.

The Invercauld was wrecked on May 10th 1864, six of the crew being drowned, commanded by Capt. George Dalgarno. Only 3 out of 19 castaways survived.
