Eating Their Own

I just finished reading another book by Nathaniel Philbrick, "In the Heart of the Sea" - the tragedy of the Whaleship Essex. I enjoyed this as much as "Mayflower".

Philbrick is a talented writer, and his historical narrative is an entertaining read. The Essex shipped out of Nantucket and was rammed and sunk by an eighty foot sperm whale, 3000 miles from the South American coast in the South Pacific.

The survivors resorted to cannibalism, as they traversed the Pacific in open 25' whaleboats for the next ninety days. Herman Melville loosely used the incident for his depiction of "Moby Dick", although the focus of this story is what happened after the ship sank. The Essex was scuttled in ten minutes.

Although I've seen companies resort to eating their own in the past few years, the tribulations on that Whaleship were the real thing.
