Indomptable exchanged broadsides with HMS Belleisle before tacking to the South-East, firing on Revenge, Dreadnought and Thunderer, before observing Gravina's signals and sailing to Cadiz.
Four days later, on the 25th, Indomptable rescued survivors of the wreck of Bucentaure off Cadiz and anchored near Rota. During the night, her cables broke and she was thrown on the shore, where she was wrecked with only 150 survivors out of 1200 men. Hubert drowned.
