Henry Nicholas John Gunther was an American soldier and possibly the last soldier of any of the belligerents to be killed during World War I. He was killed at 10:59 a.m., about one minute before the Armistice was to take effect at 11:00 a.m.

The Armistice of 11 November 1918 was the armistice signed at Le Francport near Compiègne that ended fighting on land, at sea, and in the air in World War I between the Entente and their last remaining opponent, Germany. Previous armistices had been agreed with Bulgaria, the Ottoman Empire and Austria-Hungary. It was concluded after the German government sent a message to American president Woodrow Wilson to negotiate terms on the basis of a recent speech of his and the earlier declared "Fourteen Points", which later became the basis of the German surrender at the Paris Peace Conference, which took place the following year.
