On 8 July 1782, "Bretagne" departed Brest under Captain Charles Picot de Dampierre to join the franco-Spanish combined fleet still besieging Gibraltar, arriving on 11 along with "Invincible", "Robuste", "Protecteur", "Actif", "Zodiaque", "Bien Aimé" and "Guerrier". Her cutter rescued men from the crew of the Spanish floating battery "Talla Piedra" on 13 September. "Bretagne", under Dampierre, blockaded Gibraltar until 10 October, when a gale damaged her rigging, killing a helmsman and ripping anchors from the ship. On 13 October 1782, the fleet moved to intercept a British squadron, resulting in the Battle of Cape Spartel on 20 where "Bretagne" sustained 5 men wounded. "Bretagne" then returned to Cadiz harbour in preparation for an expedition to America under Admiral d'Estaing, but by then the Peace of Paris had been concluded and "Bretagne" returned to Brest.
