After the British landing at Head of Elk (present-day Elkton, Maryland), on August 25, 1777, the British Army maneuvered out of the Chesapeake basin and towards Valley Forge. Following the Battle of Brandywine (September 11, 1777) and the abortive Battle of the Clouds (September 16), on September 18 several hundred soldiers under General Wilhelm von Knyphausen raided the supply magazine at Valley Forge. Despite the best efforts of Lieutenant Colonel Alexander Hamilton and Captain Henry "Light Horse Harry" Lee, the two Continental army officers selected to evacuate the supplies from Valley Forge, Crown soldiers captured supplies, destroyed others, and burned down the forges and other buildings.
