I only regret that I have but one life to lose for my country. _ Nathan Hale (1755 - 1776)
As a soldier in the Continental Army during the American Revolutionary war, Nathan Hale volunteered for an even more dangerous task. He became a spy and was tasked to go behind enemy lines, infiltrate the British Army and send back intelligence reports to his commanders.
Its not that being a soldier was an easy task, a safer one. No, but being a spy posed a much greater risk. Espionage was immediately punishable by death - no questions asked.
Unfortunately for Hale, he was caught. Other accounts have it that he was betrayed but that is secondary to the matter at hand. Just before being hanged, Hale said, among other things that "I only regret that I have but one life to lose for my country."
