And whereas King Don Antonio hath made very honest request unto us (upon hope he conceiveth that the noblemen and gentlemen of Portugal, so soon as they shall see him repair upon that coast with convenient forces, will presently take arms for him and will seek to expulse the Spaniards) that somewhat may be attempted by you for the recovery of his said kingdom, which as he conceiveth may be easily done in respect of the great goodwill that is borne unto him by the people there [and the evil will borne by them to the Spaniards inserted above by Burghley] we would have you carefully and substantially to inform yourselves before you proceed to attempt anything to that purpose [inserted by Burghley over that way crossed out] whether the people stand so affected towards him as he pretendeth … And in case upon enquiry you shall find that neither the love borne unto him is so great as he pretendeth and that the forces of the King of Spain are such as nothing can be attempted without very great hazard, our pleasure is that you shall then forbear to attempt anything [towards Lisbon for any enterprise to be there attempted other than the destroying of the ships there inserted above by Burghley].
