Samuel Morland, sent by Oliver Cromwell's government to investigate on the ground within weeks of the massacre, compiled a village by village list of the dead totaling one thousand seven hundred and twelve individually recorded victims, the most systematic contemporary count the episode has. Later historians, working from the same records together with accounts of refugees who subsequently died of exposure, starvation and further violence through the summer of 1655, commonly place the fuller toll far higher, into the four to six thousand range Muston's history of the Waldensian church discusses. This atlas records the range between Morland's documented count and the widely cited higher modern estimate rather than treating either alone as settled, since Morland's list, however careful, could only record deaths his investigation reached in the weeks immediately following the violence.
No international body has made a genocide or crimes against humanity determination for the massacre, which predates the modern vocabulary for one by centuries. Its recognition instead came at the time and through the centuries since: Cromwell's diplomatic intervention forced a formal Ducal declaration restoring Waldensian toleration within four months of the killings, and Milton's sonnet fixed the massacre in the wider literary memory of Protestant Europe. The Piedmontese Easter remains a defining episode in Waldensian communal memory today, one of the clearer cases in this atlas's record of a persecution answered, within the same year, by organized international diplomatic pressure rather than by silence.
