Fort William and Mary - Aftermath

Aftermath

In response to a call for aid from Boston by Governor John Wentworth, the armed hydrographic survey sloop Canceaux arrived to keep the peace in New Hampshire on December 17, followed by the twenty-gun frigate Scarborough on December 19, with numerous marines aboard. The Governor and his family were driven from their home in Portsmouth in the summer of 1775 and forced to take refuge in the fort, guarded by the guns of British warships. Britain finally gave up on the colony of New Hampshire in order to focus attention on the military situation in Massachusetts and abandoned the fort, removing its remaining equipment to Boston along with Governor Wentworth.

The supplies captured by Patriots in December of 1774 were later used by New Hampshire's forces against the British military, including in the Siege of Boston.
