Arguably the largest force of Marines ashore occurred in Boston in 1775, where General Gage sought as many reinforcements as he could get. Approximately 1,160 Marines were provided by the Admiralty, eventually being organized into two battalions along Army models. Many of these Marines saw service during the battles of 1775, making significant impacts at the battles of Lexington and Concord and later Bunker Hill. After the Battle of Bunker Hill, Marine and Army forces were bottled up in Boston by colonial militia forces and were eventually forced to evacuate in March 1776 to Halifax, Nova Scotia. After spending nearly a year of inaction in Halifax, the Marines were eventually transferred back to various ships of the Fleet, destined to participate in later events during the War. |

Marines also took part in the defense of Newport, Rhode Island in 1778. The British garrison, which included four army battalions, six Hessian battalions and numerous loyalist units, repulsed American hopes of capturing Newport and Narragansett Bay for use as a base for the French and Continental Navies. |

Virginia was also an early hotbed of rebellion. The Royal Governor of the colony, Lord Dunmore, called upon the Marines to seize the gunpowder stored in Williamsburg to keep it from falling into the hands of the increasingly belligerent American rebels. As hostilities erupted, Dunmore used the crown forces at his disposal, including the Marines from several Royal Navy ships, to attack gathering rebel militia forces at the Battle of Kemp’s Landing. Later, Dunmore would attempt to block communications between Virginia and North Carolina by constructing a fort near a large bridge on the main road between the two colonies. The colonists responded to the threat, sending troops to confront Dunmore’s forces at the Battle of Great Bridge. |

SOUTHERN COLONIES Marines were also present during the defense of Savannah, the Siege of Charleston, and the conquest of South Carolina. They also took part in several raids up the many rivers and creeks by boat. Their participation in the capture of Fort Moultrie was one of the notable British successes of the southern campaign. |

Later in the war, when the British returned to establish a foothold in Tidewater Virginia, Marines from several ships accompanied turncoat Brigadier General Benedict Arnold on his first assignment since defecting to the British. Together, and with reinforcements from several army and militia units, they established a base of operations at Portsmouth VA from which they conducted raids along the James River to destroy colonial military stores and production centers.
Marines were also present with General Cornwallis at Yorktown, where they helped defend the Fusiliers’ Redoubt, prompting Cornwallis to state that they “maintained their post with uncommon gallantry.” |
