The
Second Continental Congress passed a resolution on 10 June 1775, in creating the
Continental Army from all the available colonial forces and militias around
Boston; they appointed
George Washington, a
Congressman of
Virginia, as the
General and Commander-in-Chief of the Continental Army. It was vital for General Washington's army to seize Boston to help interdict the flow of supplies and reinforcement of troops to the British. Under-equipped and lacking gunpowder and supplies, Washington greatly depended in supplying his force from the surrounding colonial armies and navies, and from any cache that came from captured British ships of
provision and
matériel values. By mid-August 1775, General Washington formed his own "
maritime fleet" due to the limitations of funding and resources from the Continental Congress. On 24 August, he brought a schooner into service, , to interdict any British ships in the
Massachusetts Bay.
Hannah became the first American-built ship in the fleet, also becoming the founding vessel of the
United States Navy. Following, Washington relied on the 14th Continental Regiment, or "
Marblehead Regiment", consisting of a militia of skilled
mariners throughout
New England, in providing him a naval assault force for the upcoming siege in the
Lake Champlain area. Other ships manned by this regiment included the schooners , , , , and . Captain
Nicholas Broughton sailed
Hannah off the coast of Massachusetts on 7 September and captured the British sloop
HMS Unity. On 10 October, the sailors and Marines of the Marblehead Regiment participated in the battle between
Hannah and the British sloop in the harbor of
Beverly, Massachusetts.
Hannah was
grounded by her captain in order to remove her powder and armaments, preventing their capture by the British. By 5 November 1775, Washington's regiment of Marines aboard
Harrison participated in the capture of the British supply vessels
Polly and
Industry off the coast of
Boston, Massachusetts. Two days later, on 7 November,
Lee captured the British sloop
HMS Ranger in the
Massachusetts Bay. Washington's Marblehead Regiment aboard
Hancock and
Franklin made an unopposed landing at
Charlottetown, Prince Edward Island, on 17 November 1775. Three days later, they raided
Canso Harbor,
Nova Scotia. The
Harrison and her Marine detachment fought against three British
warships in
Boston Harbor on 24 November 1775. On 27 November 1775,
Lee and her Marine detachment captured a sloop off the
New England coast. Over the next several weeks, these Marines participated in the capture of several British ships off the coast of New England. Two British frigates captured the American warship on 3 December, taking the sailors and Marines amongst her crew prisoner. A company of Washington's Fleet (along with his "Marblehead" Regiment) aboard
Franklin, commanded by Captain
James Mugford (of Commodore
John Manly's Continental Navy squadron), captured the British transport ship
Hope on 17 May 1775. The ship was stocked with 1,000
carbines and 75 tons of gunpowder. On June 16, Washington's fleet captured two British troopships attempting to reinforce Boston, which the British Army had evacuated prior their arrival. In the Atlantic on 7 June, the frigates
Hancock and
Boston, along with their Marine detachments, captured the British frigate HMS
Fox. ==State navies==
