“At the transcript of the trial, one of Gilles servants Henriet (an accomplice to his crimes) described the actions of his master, which were essentially:

Henriet soon began to collect children for his master, and was present whilst he massacred them. They were murdered invariably in one room at Machecoul. The marshal used to bathe in their blood; he was fond of making Gilles do Sillé, Pontou, or Henriet torture them, and he experienced intense pleasure in seeing them in their agonies. But his great passion was to welter in their blood. His servants would stab a child in the jugular vein, and let the blood squirt over him. The room was often steeped in blood. When the horrible deed was done, and the child was dead, the marshal would be filled with grief for what he had done, and would toss weeping and praying on a bed, or recite fervent prayers and litanies on his knees, whilst his servants washed the floor, and burned in the huge fireplace the bodies of the murdered children. With the bodies were burned the clothes and everything that had belonged to the little victims. An insupportable odour filled the room, but the Maréchal do Retz inhaled it with delight.”
