The Ardeatine Caves are associated with the killing of 335 civilians in a German reprisal during the Second World War. In the novel, the site connects the wartime selection and execution of prisoners to a later courtroom dispute over whether reprisals could ever be lawful, and what limits international law placed on them.

Wartime Reprisal

As Hans Meyer explains the operation, he links it to an attack in Rome in which thirty-three German soldiers were killed. The reprisal at the Ardeatine Caves was carried out under General Kesselring: 335 civilians were shot, although they had no connection to the attack. Meyer’s account also notes that a child was among them. The disparity between the soldiers killed and the civilians selected makes the site central to the novel’s contrast between the language of military retaliation and the people made to bear its consequences.

The Courtroom’s Legal Question

The Ardeatine Caves return as a point of reference during expert testimony at the trial. The court’s description of the killing as a barbaric remnant of the past is set against its further ruling that reprisal killings could, in extreme cases, be considered legitimate. The testimony makes clear that this was not an unqualified permission: the killing of women and children was excluded, executions could not be cruel, prisoners could not be tortured beforehand, and serious efforts had to be made to find and capture those responsible for an attack.

Limits and Significance

The testimony also addresses the scale of reprisal. It states that international law supplied no fixed ratio for civilian deaths in response to the death of a soldier, while insisting that reprisals must not be excessive. Hitler’s demand in 1941 for one hundred people to be killed for each German soldier was given as an example of a ratio that international law would not have permitted. The Ardeatine Caves thus stand in the novel not only for a specific mass killing, but also for the tension between legal limits on retaliation and the devastating human consequences of treating civilians as its price.
