On the morning of 10 May 1775, Colonel Allen and 83 of his Green Mountain Boys entered the somnolent fort on the morning of 10 May alongside Col. Benedict Arnold, an officer appointed by the Second Continental Congress.
"“I landed eighty-three men near the garrison, and sent the boats back for the rear guard commanded by Col. Seth Warner. . . . The men being, at this time, drawn up in three ranks, each poised his firelock. I ordered them to face to the right, and, at the head of the centre-file, marched them immediately to the wicket-gate aforsaid, where I found a sentry posted, who instantly snapped his fusee at me; I ran immediately toward him, and he retreated through the covered way into the parade within the garrison, gave a halloo, and ran under a bomb-proof. My party who followed me into the fort, I formed on the parade ground in such a manner as to face the two barracks which faced each other. The garrison being asleep (except the centries), we gave three huzzas which greatly surprised them.”"
