By the beginning of 1579, however, the aspect of European politics had become so threatening that the practised hand of the Lord Treasurer was needed at the helm, and thenceforward his influence was again in the ascendant. Simier was making violent vicarious love to the Queen, and letters of the most extravagant description were exchanged between the young Prince and Elizabeth, whilst really sincere and earnest efforts were being made in favour of the match by Henry III. and Catharine de Medici. Commissioners and ambassadors went backwards and forwards, and the conditions, not only of the Queen’s marriage, but of a national offensive and defensive alliance between France and England, were under discussion. Henry III. was ready, he said, to submit to any conditions desired by Elizabeth, and Alençon was almost blasphemous in his praising of the charms of his elderly flame. There were two main reasons for this drawing together of England and France. Don Juan was dead, and the military genius and diplomacy of Alexander Farnese had once more separated Catholic Belgium from Protestant Holland (Treaty of Arras, January 1579). Orange himself still clung to the hope of consolidating a united Flemish nation, including north and south, and desired to use Alençon, with the Queen of England’s support, for that purpose but there was no enthusiasm in Holland for the idea; and in the meanwhile Alençon was isolated in Catholic Flanders, with his own brother raging at the compromising position in which he placed him, and ordering him to return to France. It was evident to Henry that the only way in which his turbulent brother could be established in Flanders, without causing both Spanish and English arms to be used against him, was to let him depend solely upon Elizabeth and Orange, whilst France stood aloof. This was one of the reasons for the closer relations desired by Catharine and her son. The other was more important still. The young King of Portugal had fallen in battle in Morocco, and the new King was an aged, childless Cardinal. Philip of Spain was already intriguing for the succession, which he claimed. The possession of the fine harbours and Atlantic seaboard of Portugal by Spain would enormously increase her maritime potency, to the detriment of England and France; and it was felt that these powers must unite to resist the common danger. That Lord Burghley was early alive to its importance is proved by a genealogical statement of his relating to the Portuguese succession immediately after the death of the King Don Sebastian[422] (August 1578), and several memoranda of subsequent date on the subject.
