Who is Captain Renaud in Servitude et grandeur militaires?

In Alfred-Victor de Vigny’s 1835 work Servitude et grandeur militaires (translated as The Military Necessity), Captain Renaud is a central character featured in the book's third story.1

Renaud is depicted as an old Napoleonic soldier who serves as a profound portrait of human greatness. Through this character, Vigny explores the complex moral condition of the soldier, who is bound by the requirements of his profession to kill while simultaneously being condemned to a life of passive, unquestioning obedience. The character embodies the "tormented conscience" of a soldier who detests the violence of war yet continues to fight with dedication, reflecting Vigny's own focus on the dignity and suffering inherent in military life.12
