He took part in the Croisière du Grand Hiver, where he was tasked to conduct rescue operations when Superbe foundered after taking in water; Quérangal managed to save the 936-man crew and left the ship last, and returned to Océan where he was promoted to captain on the spot.
Returned to Brest, Quérangal was given command of the frigate Cocarde, leading a three-frigate squadron to patrol off France and Ireland.
He managed to reach the designated landing spot in Bantry Bay, where he waited the rest of the fleet until it became clear that the expedition was a failure.
He briefly took part in the Saint-Domingue expedition, though Duquesne aborted her journey early due to a leak and had to return to Toulon.
Upon his arrival, Admiral Latouche Tréville put him in command of a division comprising Duquesne, Intrépide and the 40-gun Sibylle, along with two corvettes and a number of transports, and tasked with supporting general Clausel in his attack of Port-de-Paix.
Quérangal requested that his crew, weakened by fevers from 863 men to only 235, be reinforced, but none fit for duty could be assigned to Duquesne before she departed.
