On 22 July 1805, in the battle of Cape Finisterre the quartermasters of "Indomptable" spotted the British fleet under Sir Robert Calder. After a violent artillery exchange, the fleets became separated in the fog. Exhausted after six months at sea, the fleet anchored in Ferrol before sailing to Cádiz to rest and refit. With his command under question and planning to meet the British fleet to gain a decisive victory, Villeneuve left Cádiz and met the British fleet near Cape Trafalgar.
