For those of you with a strong stomach or a bit of a morbid curiosity, here are some wikipedia links on cannibalism in the nineteenth century. There was quite a lot of cases of cannibalism in the nineteenth century, mostly by shipwrecked sailors.
The Boyd Massacre
The Boyd massacre took place in 1809, when local Maori killed 66 people at Whangaroa, a northern New Zealand harbour, as revenge for the crew of the ship The Boyd whipping the son of a chief who refused to work.
The Cospatrick was a sailing ship that was the victim of one of the worst shipping disasters to a merchant ship during the 19th century. The ship caught fire south of the Cape of Good Hope on 17 November 1874 while on a voyage from Gravesend, England to Auckland, New Zealand. Only 3 of 472 persons on board at the time ultimately survived.
Dalles des Morts
Dalles des Morts, also known as Death Rapids in English, was a famously bad stretch of the Columbia River upstream from Revelstoke, British Columbia, Canada, now submerged beneath the waters of the Lake Revelstoke Reservoir.
The Donner Party
The Donner Party was a group of California-bound American settlers caught up in the “westering fever” of the 1840s. After becoming snowbound in the Sierra Nevada in the winter of 1846–1847, some of the emigrants resorted to cannibalism.
The whaleship Essex
The whaleship Essex left Nantucket, Massachusetts in 1819 on a voyage in the whaling grounds of the South Pacific to hunt sperm whales. On November 20, 1820, the Essex was struck two times by a sperm whale. The ship sank 2,000 miles (3,700 km) west of the western coast of South America. The twenty sailors set out in three small whaleboats, with wholly inadequate supplies of food and water, and landed on uninhabited Henderson Island.
The Medusa (original French name: La Méduse) was a French frigate that gained notoriety when it struck the Bank of Arguin off the coast of Senegal in 1816, resulting in the catastrophic evacuation of its company, and one of the most infamous shipwrecks of the Age of Sail.
