Here in the United States, people were obsessing about an eclipse that could be viewed by millions throughout the country. Apparently this was possible for the first time since the 1970s. The eclipse was treated with a lighthearted celebratory fare, with the only concern being people not look directly into the sun for fear of damaging their eyes. Not everyone got the message however. It was on this day though, 186 years ago, that an eclipse proved to be a harbinger of one of the most storied rebellions in American history.
