 On 19 December, the first winter storm struck the French squadron. In the heavy waves and high winds, first Windham and then Vénus were separated from the convoy, Manche marshalling the remaining ships and continuing the southwards journey. Windham's French prize crew were able to regain control of their ship and continued on to Île de France alone, but Vénus was struck by an even larger hurricane on 27 December and lost all three topmasts in the gale. The French crew panicked as the storm began, and refused to attend to the sails or even close the hatches: as a result the vessel almost founded as huge amounts of water poured into the ship. In desperation, Hamelin called Captain Stewart to his cabin and requested that his men save the ship but demanded that Stewart give his word that his men would not attempt to escape or seize the frigate. Stewart refused to give any such guarantee but agreed to help repair the damage and bring the ship to safety. After securing the weapons lockers aboard, Hamelin agreed and Stewart and his men cut away the wrecked masts and pumped the water out of the hold, repairing the ship so that she was able to continue her journey without fear of foundering.
