Reflecting back on the period of the Catholic League, the magistrate and historian Jacques-Auguste de Thou expressed mixed feelings about friar Robert Chessé. Chessé had protected De Thou during the Day of the Barricades, the week-long revolt against royal authority in Paris that began on May 12, 1588. During these violent days, the Catholic League took control of the major municipal institutions, and its supporters hunted down well-known royalists, including De Thou. Many were imprisoned if not beaten and killed, including those royalist magistrates of the Parlement and members of the municipal government who failed to escape Paris in time. De Thou fled to the Paris friary for protection sometime after May 12, and he remained hidden there for several days until it was safe for him to depart. De Thou expressed his gratitude to Chessé in his Histoire universelle for saving him from the League, but he could not hide his disappointment in the friar's subsequent political radicalism. Chessé was vain, he said, and he let his religious fanaticism replace his loyalty to the king. De Thou was well aware that only eighteen months after the Day of the Barricades, Chessé was caught by the forces of Navarre in the city of Vendôme and executed for treason. The charge against Chessé was conspiracy on behalf of the League to overthrow the royalist government of Tours.
