The Battle of Caporetto appears as both a military catastrophe and a lasting political memory: in Benito Mussolini’s retrospective account, it marks the death throes of an era, while the later inquiry into the defeat rekindles disputes over responsibility even after Italy’s final victory. The narrative gives no account of the battle’s tactics or immediate course; instead, it emphasizes the scale of the defeat and the controversies that returned around it.

The Defeat as a Historical Rupture

Mussolini places Caporetto behind him on October 24, 1917, and characterizes it as the greatest military defeat of all time. His account describes an army of a million soldiers destroyed in a single weekend. The battle is not presented as an isolated military episode: it becomes a marker dividing one political era from another, a remembered collapse that stands behind the postwar present.

That framing gives Caporetto a double significance. It is a specific date and defeat, but also a shorthand for the destruction of the world that had preceded the postwar crisis. The narrative offers this interpretation through Mussolini’s backward glance rather than through a detailed reconstruction of events on the battlefield.

The Inquiry and the Return of Controversy

Years after the defeat, the publication of the government inquiry into Caporetto revived scrutiny of the army’s high command. The findings renewed opponents’ arguments against the war, despite the subsequent triumphant final victory. In the narrative, military defeat therefore continues to exert force after the fighting has ended: official documents reopen questions that victory had not settled.

The controversy becomes personal as well as political. Giacinto Menotti Serrati, who had once provided Mussolini with shelter and work when he was a poor young emigrant, revived the accusation that Mussolini had founded Il Popolo d’Italia with secret French funding. Mussolini answered by reviving an insinuation that Serrati had been a spy. Their exchange descended into insults, old grievances, and mutual suspicion. Caporetto’s inquiry thus reactivated not only disputes about military command and intervention, but also the antagonisms of the political world that had formed around the war.

Memory in the Postwar Narrative

Mussolini places Caporetto beside another decisive break in his own past: his expulsion from the Socialist Party in November 1914. The juxtaposition does not make the two events equivalent. Rather, it presents the military defeat and the political rupture as separate thresholds behind the narrator, helping define the distance between his former position and the postwar role he claims for himself.

The battle’s importance in this account lies partly in that retrospective placement. Caporetto is recalled not through a scene of combat but as a defeat whose meaning returns through memory, official investigation, and renewed polemic. Even after victory, the event remains unsettled: its military responsibility is debated, its political significance is reclaimed by opponents of the war, and its memory supplies a stark measure of the rupture from which the postwar order emerged.
