Juan Fernández de Velasco y Tovar, 5th Duke of Frías

The resident Spanish ambassador, the Count of Villamediana, asked King James if Velasco could be lodged at Somerset House, and Anne of Denmark granted his request.

In May, the Venetian diplomat Nicolò Molin heard the delay annoyed King James who felt he was being slighted.

James wrote to Cecil that he would hunt in the season and "I doubt if the Constable of Castille hath any power in his commission to stay the course of the sun".

The Constable gave Prince Henry a Spanish horse with a rich saddle and bridle and an embroidered doublet with a sash.

He initially disagreed over a detail concerning duties paid by English merchants carrying German goods into Spain.

[30] King James claimed that melon and oranges, which he shared as desert with the Constable, were Spanish fruits transplanted in English soil, a symbol of new international friendship.

[33] After the banquet, the Constable was confined to his bed for a couple of days with lumbago,[34] or, according to Nicolò Molin, an "attack of the kidneys",[35] and the Count of Arenberg was laid up with gout.

[36] Due to the Duke's indisposition, King James came to Somerset House for the traditional leave taking,[37] and gave him a diamond ring (supplied by Martin van Somer) as a token of the peace treaty as a marriage.

[39] Philip III had hoped that the Constable would negotiate for the toleration and free exercise of religion for Catholics in James's realms, but he preferred to concentrate only on concluding the peace.

He wrote a report on religion in England for Philip III in November, noting James's distaste for Puritanism.

[40] As a parting gift, King James sent the Duke of Frías a service of vintage gilt plate, extracted from the Jewel House by Edward and Henry Cary.

[49] The Constable gave gifts of jewels and money to courtiers and officials, and the Queen's ladies including Jane Drummond.

[54] The plate given to the Constable included the French medieval royal gold cup and two Tudor water pots with spouts like dragons, attributed to Cornelis Hayes.

In 1595, he led the Spanish forces in the Battle of Fontaine-Française against the French, where he let victory slip through his fingers, due to excessive caution.
