Two hundred forty years ago, just weeks after the colonies had declared their independence from Great Britain, George Washington’s army was outnumbered and outmaneuvered. The rebels would likely have been wiped out, and the revolution over before it began,.. except for the elite unit of Maryland fighters who repeatedly attacked British headquarters, buying a precious hour for the bulk of Washington’s army to escape. Two hundred-fifty-six Marylanders were killed in the Battle of Brooklyn. Where they are buried is still a mystery. But the Maryland regiments went on to supply the margin of victory in dozens of battles. Military historian Patrick O’Donnell tells their story in "Washington’s Immortals: The Untold Story of an Elite Regiment Who Changed the Course of the Revolution".
