After the Battle of Sadras on 17 February 1782,[5] Suffren wrote that he had "correctly kept his station".[10]
At the Battle of Providien on 12 April 1782, [6] Forbin's Vengeur stayed largely out of the action.[11] Engaged by HMS Exeter, she veered to aim her broadside at her, which prevented her from closing the distance. In consequence, the two ships exchanged fire from too large a distance and were ineffectual.[12]
At his return to France, he was imprisoned at Pont-Saint-Esprit castle.[13][2] His conduct was later attributed "more to incompetence and a lack of character than to ill will", he was freed and asked to resign. He was retired on 12 September 1784.[2][Note 1]
^"Sa Majesté, ayant été informée que cet officier avait montré dans sa conduite plus d'incapacité et de défaut de caractère que de mauvaise volonté, elle l'a fait mettre en liberté, en lui enjoignant de demander sa retraite, qui lui a été accordée sans satisfaction, le 12 september 1784".[2]
