 A fleet of five galleys and five caravels captained by Carlos de Valera and Andrés Sonier intercepted them in Sanlúcar de Barrameda, and were victorious after a hard-fought battle.Valera gathered a fleet of three Basque ships and nine Andalusian caravels (25 caravels according to Palencia), all heavily armed.There was no longer any possibility of intercepting the Portuguese fleet so he decided, after stopping at Porto Santo Island, to head towards the island of António Noli in the Cape Verde archipelago, near the coast of Guinea.
