Who died as a spy for his country?

One of the most notable spies in history who died for his country is Nathan Hale, an American Revolutionary War soldier. He was captured by British forces in 1776 while gathering intelligence and famously declared, "I only regret that I have but one life to lose for my country" before being executed. His bravery and sacrifice have made him an enduring symbol of patriotism and espionage in American history.
