I Have Done My Duty

While standing on the poop deck of his ship, amid the heat and fire of severe combat, Admiral Horatio Nelson, a great British naval hero, received his mortal wound. Afterward he lay in his stateroom and was informed that the battle was certain in favor of his country's flag. After hearing this assurance, he breathed out his spirit with these words: "Thank God! I have done my duty."
