Robespierre visited Marie Therese on the 11th of May, but no one, according to the legend, entered the dauphin's room for six months until Barras visited the prison after the 9th Thermidor (July 2 7, 1794).
Barras's account of the visit describes the child as suffering from extreme neglect, but conveys no idea of the alleged walling in.
The child made no complaint to Barras of his treatment, probably because he feared to do so.
The weak parts of this story are the sudden and unexplained departure of the Simons; the subsequent useless cruelty of treating the child like a wild beast and keeping him in a dark room practically out of sight (unless any doubt of his identity was possible), while his sister was in comparative comfort; the cause of death, declared to be of long standing, but in fact developed with such rapidity; the insufficient excuse provided for the child's muteness under Gomin's regime (he had answered Barras) and the irregularities in the formalities in attending the death and the funeral, when a simple identification of the body by Marie Therese would have prevented any question of resuscitated dauphins.
According to him Barras determined to save the dauphin in order to please Josephine Beauharnais, the future empress, having conceived the idea of using the dauphin's existence as a means of dominating the comte de Provence in the event of a restoration.
