American Revolutionary officer who attempted to spy on the British and was hanged.

A graduate of Yale University (1773) and a schoolteacher, Hale joined a Connecticut regiment in 1775, served in the siege of Boston, and was commissioned a captain (1776). He went to New York with William Heath's brigade and is said to have participated in the capture of a provision sloop from under the guns of a British man-of-war. Hale was captured by the British while attempting to return to his regiment, having penetrated the British lines on Long Island to obtain information. He was hanged without trial the next day.

Hale is regarded by American Revolutionary tradition as a hero and a martyr. He is supposed to have said before his death that his only regret was that he had but one life to lose for his country, a remark similar to one in Joseph Addison's play Cato.
