In 1836, the Lydia, a Nantucket whaleship, was struck and sunk by a sperm whale, as was the Two Generals a few years later. In 1850, the Pocahontas, out of Martha’s Vineyard, was rammed by a whale but was able to reach port for repairs. Then, in 1851, the year that Moby-Dick was published, a whaleship was attacked by a sperm whale in the same waters where the Essex had been sunk thirty-one years before.
