Allen received a message from members of an irregular Connecticut militia in late April, following the battles of Lexington and Concord, that they were planning to capture Fort Ticonderoga and requesting his assistance in the effort. Allen agreed to help and began rounding up the Green Mountain Boys, and 60 men from Massachusetts and Connecticut met with Allen in Bennington on 2 May, where they discussed the logistics of the expedition. By 7 May, these men joined Allen and 130 Green Mountain Boys at Castleton. They elected Allen to lead the expedition, and they planned a dawn raid for May 10. Two small companies were detached to procure boats, and Allen took the main contingent north to Hand's Cove in Shoreham to prepare for the crossing.
