Following the French Revolution, radical military reforms created conditions for new physical and emotional intimacy between soldiers, establishing a model of fraternal affection that would persist from the revolutionary and Napoleonic wars through the Franco-Prussian War and World War I.

Based on extensive research in French and American archives, and enriched by his reading of Napoleonic military memoirs and French military fiction from Hugo and Balzac to Zola and Proust, Brian Joseph Martin's view encompasses a broad range of emotional and erotic relationships in French armies from 1789 to 1916. He argues that the French Revolution's emphasis on military fraternity evolved into an unprecedented sense of camaraderie among soldiers in the armies of Napoleon. For many soldiers, the hardships of combat led to intimate friendships. For some, the homosociality of military life inspired mutual affection, lifelong commitment, and homoerotic desire.
