But the core of what she did is there: she survived.

In conditions that killed everyone around her, that isolated her completely from human contact, that subjected her to cold and hunger and grief and the physical demands of maintaining a body alive in an environment that had not been designed for human habitation — she survived.

And when she came back, she told someone about it, and that person told someone else, and eventually it was written down, and eventually we can read it.

That is the legacy of Marguerite de la Rocque: not a heroic gesture, not a political act, not a deliberate contribution to history.
