Overview
The Assisi Underground: The Priests Who Rescued Jews is a 1978 novel written by Alexander Ramati based on a true-life account, told by Father Rufino Niccacci, of events surrounding the Assisi Network, an effort to hide 300 Jews in the town of Assisi, Italy during World War II.
Plot
In the Italian town of Assisi during World War II, 300 Jews were sheltered and protected by a peasant turned priest, Father Rufino Niccacci. He dressed many of them as monks and nuns, taught them Catholic ritual, and hid them in the monasteries. Others lived in parishioners' homes and, with fake identity cards, found jobs and blended into the community. The town's printing press, which during the day printed posters and greeting cards, at night clandestinely printed false documents that were sent by courier to Jews all over Italy.
Not a single refugee was captured in Assisi. No one who participated in the rescue operation ever betrayed it.
