Green Mountain Boys
The Green Mountain Boys were an irregular militia formed in 1770 in the New Hampshire Grants territory—now Vermont—to defend settlers' land claims against assertions of jurisdiction by New York colonial authorities, who sought to nullify New Hampshire's prior grants through legal and enforcement measures.[1][2] Organized primarily around Bennington under the leadership of Ethan Allen, a local landowner and speculator with familial ties to many members, the group resisted New York sheriffs, surveyors, and courts through organized intimidation, property destruction, and sporadic violence, viewing New York's actions as an illegitimate overreach that threatened their established settlements.[1][2] At the outbreak of the American Revolutionary War in 1775, the Green Mountain Boys, led by Allen in collaboration with Benedict Arnold, executed a surprise dawn assault on May 10 that captured Fort Ticonderoga from its lightly garrisoned British force, securing artillery crucial for the Continental Army's early campaigns without significant casualties.[3][4] This feat elevated their status from regional insurgents to recognized Patriot contributors, prompting the Continental Congress to authorize a regiment under Seth Warner, Allen's successor after his capture during a subsequent invasion of Canada.[5] The reformed unit played a decisive role in the 1777 Battle of Bennington, where Warner's forces ambushed and routed a British foraging detachment, disrupting enemy supply lines and bolstering American morale in the Saratoga campaign.[5] While celebrated for their martial exploits against British forces, the Green Mountain Boys' prewar activities drew condemnation from New York officials as lawless vigilantism, reflecting deeper colonial disputes over land tenure and governance that underscored the decentralized nature of frontier resistance preceding unified rebellion.[2] Their efforts not only preserved Vermont's autonomy—culminating in the short-lived Vermont Republic—but also exemplified self-reliant defense rooted in settlers' empirical stake in the land against distant administrative claims.[6][7]
