"The Road of the Eagles" (also known as "Conan, Man of Destiny") is a 1955 fantasy novelette by American writer L. Sprague de Camp, based on a story by Robert E. Howard by the same name.
De Camp gave Ivan Sablianka's role to Conan, changed the setting from the Ottoman Empire in 1595 into Howard's Hyborian Age and extensively re-worked the plot and story-line so that a new "Howard" story could be added to the collection Tales of Conan in 1955.
"The Road of the Eagles" was first published in Fantastic Universe in December 1955 under the title Conan, Man of Destiny.
[1] In the same year it was also published as part of Tales of Conan but now under the original title "The Road of the Eagles".
[2] The original story, now renamed "The Way of the Swords", can be found in The Road of Azrael published in 1979.
