Of the 40,000 survivors, perhaps 500 are still alive; I tracked down and interviewed 40 of them – ordinary people who were left behind or managed to reach the end, but with stories that are highly instructive.
De los 40.000 supervivientes, tal vez 500 sigan vivos; localicé y entrevisté a 40 de ellos: personas comunes y corrientes que quedaron rezagadas o lograron llegar hasta el final, pero que podían contar historias muy instructivas.
