"Finally, the executioner, Samson, said to Monsieur Le Breton that there was no way or hope of succeeding, and told him to ask their Lordships if they wished him to have the prisoner cut into pieces. Monsieur Le Breton, who had come down from the town, ordered that renewed efforts be made, and this was done; but the horses gave up and one of those harnessed to the thighs fell to the ground. The confessors returned and spoke to him again. He said to them (I heard him): 'Kiss me, gentlemen.' The parish priest of St Paul's did not dare to, so Monsieur de Marsilly slipped under the rope holding the left arm and kissed him on the forehead. The executioners gathered round and Damiens told them not to swear, to carry out their task and that he did not think ill of them; he begged them to pray to God for him, and asked the parish priest of St Paul's to pray for him at the first mass.
"After two or three attempts, the executioner Samson and he who had used the pincers each drew out a knife from his pocket and cut the body at the thighs instead of severing the legs at the joints; the four horses gave a tug and carried off the two thighs after them, namely, that of the right side first, the other following; then the same was done to the arms, the shoulders, the arm-pits and the four limbs; the flesh had to be cut almost to the bone, the horses pulling hard carried off the right arm first and the other afterwards.
"When the four limbs had been pulled away, the confessors came to speak to him; but his executioner told them that he was dead, though the truth was that I saw the man move, his lower jaw moving from side to side as if he were talking. One of the executioners even said shortly afterwards that when they had lifted the trunk to throw it on the stake, he was still alive. The four limbs were untied from the ropes and thrown on the stake set up in the enclosure in line with the scaffold, then the trunk and the rest were covered with logs and faggots, and fire was put to the straw mixed with this wood.
"...In accordance with the decree, the whole was reduced to ashes. The last piece to be found in the embers was still burning at half-past ten in the evening. The pieces of flesh and the trunk had taken about four hours to burn. The officers of whom I was one, as also was my son, and a detachment of archers remained in the square until nearly eleven o'clock.
"There were those who made something of the fact that a dog had lain the day before on the grass where the fire had been, had been chased away several times, and had always returned. But it is not difficult to understand that an animal found this place warmer than elsewhere" (quoted in Zevaes, 201-14).
