Digby's plan was to bring over
Charles, Prince of Wales, to head a royalist movement on the island. When he joined Charles at
Jersey in April 1646, he intended to entrap him on board, but was dissuaded by Hyde. Digby then travelled to
Paris to gain Henrietta Maria of France's consent to his scheme, but returned to persuade Charles to go to Paris, and accompanied him thither. He revisited Ireland on 29 June once more, and on the surrender of the island to Parliament escaped again to France. At Paris, amongst the Royalists, he found himself in a nest of enemies eager to pay off old scores. Prince Rupert challenged him, and he fought a duel with
Lord Wilmot. He continued his adventures by serving in
Louis XIV of France's troops in the
war of the Fronde, in which he greatly distinguished himself. He was appointed in 1651
lieutenant-general in the French army, and commander of the forces in Flanders. These new honours, however, were soon lost. When Digby returned to France he was told that he was included in the list of those expelled from France, in accordance with the new treaty with
Oliver Cromwell. In August 1656 he joined
Charles II at
Bruges, and wanting revenge on the cardinal, offered his services to
John of Austria the Younger in the
Southern Netherlands. He was instrumental in effecting the surrender of the garrison of
St. Ghislain to Spain in 1657. On 1 January 1657, he was appointed by Charles II secretary of state, but shortly afterwards, he was compelled to resign office as he had become a Roman Catholic — probably with the view of adapting himself better to his new Spanish friends. Charles took him with him to Spain in 1659 on account of his "jollity " and Spanish experience. Although unwelcome to the Spanish, he succeeded in ingratiating himself, and was later welcomed by
Philip IV of Spain at
Madrid. Digby succeeded to the peerage as
2nd Earl of Bristol on the death of his father in January 1653 and was made
KG the same month. == Restoration ==
