According to Joseph Pearce, "In March 1936 the anti-clerical contagion spreading across Spain reached the streets of Toledo, the ancient city in which the Campbells had made their home. Churches were burned in a series of violent riots in which priests and nuns were attacked. During these bloody disturbances, Roy and Mary Campbell sheltered in their house several of the Carmelite monks from the neighboring monastery. In the following weeks, the situation worsened. Portraits of Marx and Lenin were posted on every street corner, and horrific tales began to filter in from surrounding villages of priests being shot and wealthy men being butchered in front of their families. Toledo's beleaguered Christians braced themselves for the next wave of persecution, and the Campbells, in an atmosphere that must have seemed eerily reminiscent of early Christians in the Catacombs of Rome, were confirmed in a secret ceremony, before dawn, by Cardinal Goma, the elderly Archbishop of Toledo and Primate of Spain. In July 1936, the civil war erupted onto the streets of Toledo, heralded by the arrival in the city of Communist militiamen from Madrid. With no one to defend them, the priests, monks, and nuns fell prey to the hatred of their adversaries. The seventeen monks from the Carmelite monastery were rounded up, herded on to the street and shot. Campbell discovered their murdered bodies, left lying where they fell. He also discovered the bodies of other priests lying in the narrow street where the priests had been murdered. Swarms of flies surrounded their bodies, and scrawled in their blood on the wall was written, 'Thus strikes the CHEKA.'"
