how did american colonel john glover play acritical part to Washington attack plan

At the start of 1776, the Marblehead Militia Regiment formally became the 14th Continental Regiment and was ordered in July to march to New York and later to Long Island. In August, Glover organized and supervised the evacuation from Long Island of 9,000 Continental troops and all of their equipment, guns, horses, and cannon, at night and under appalling weather conditions. In mid-October, Glover and 750 of his soldiers fought to a standstill a British force of more than 4,000 regulars.
