History
Prospect Hill was the location of George Washington's command post during the Siege of Boston in the American Revolution. It also served as a training facility in the American Civil War. On New Year's Day in 1776, Washington conducted a flag-raising ceremony to raise the morale of the men of the Continental Army. The standard account features the Grand Union Flag flying, although in 2006, Peter Ansoff advanced a theory that it was actually a British Union Flag instead. Others, such as Byron DeLear, have argued in favour of the traditional version of events.
