4. Washington's Ad Hoc Navy and the Formation of the Commander-in-Chief's Guard Author: Patrick O'Donnell Book Title: The Indispensables: The Diverse Soldier Mariners Who Shaped the Country, Formed the Navy, and Rowed Washington across the Delaware Upon George Washington's arrival in July 1775, the Continental Army suffered a critical shortage of black powder, forcing Washington to seek urgent supply solutions. He developed a unique trust with the Marbleheaders, whose nautical expertise he relied upon. Washington bypassed Congress to create his own Navy—a fleet of "cruisers" (including the Leeand the Warren) manned by Marblehead sailors, essentially perfect marines. Their primary goal was to intercept British transports laden with ordnance and powder. Captain John Manley, a Marbleheader, achieved a critical success, capturing one of the war's richest prizes—a ship filled with supplies that included a massive mortar used later at Dorchester Heights. Washington's Navy operated primarily out of Beverly, Massachusetts, a heavily defended, difficult-to-navigate, protected port. Additionally, Washington formed the Commander-in-Chief's Guard, or Lifeguard, which was an early precursor to the Secret Service, tasked with protecting the general and his papers. This handpicked volunteer unit was placed under the command of Marbleheader Caleb Gibbs.
