Hale worked for 3 weeks after he began spying for the Revolutionary Army. Disguised as a Dutch schoolteacher, he attempted to infiltrate New York`s British ranks to gather intelligence on the enemy`s Long Island military installations. The young man was captured, however, on the night of September 21, 1776 and hanged for treason the next morning on a gallows believed to have been erected near 63rd Street and First Avenue.Before he was hung, he uttered the words, "I only regret I have but one life to give for my country."
