On May the 30th the emperor wrote to Mendoza, his ambassador in England: '... We shall not fail to inform you... of whatever is being done here (Valladolid) with regard to the French and English ambassadors, and their commission. We shall likewise apprise madame, our aunt, but as the cipher which you possess is safer than hers, we will use yours for the purpose of transmitting our orders and wishes thereupon.... Meanwhile you will write to madame in our name, that without appearing to distrust the English in any way, she may, as of her own accord, immediately provide for the defence of the frontiers both by sea and land, in Flanders as well as in Holland and Zealand, and remember what his Reverence the Legate of England (Wolsey) said on a previous occasion, that once the Flemish frontier is broken in upon, the conquest of the land would be an easy matter. Should madame require our assistance for the protection of our dominions in those parts, you will tell her in our name that we shall do our utmost to provide her with money and troops for the emergency, and that she is to inform us, as soon as possible, of the military preparations she intends making, in doing which madame is to use your own cipher, of which a copy shall be sent to her immediately, that she herself may write to us, if she so prefers.'[129] [129] _Calendar of Spanish State Papers_, vol. iii. part II. About this time rumours of the unhappy matrimonial relations existing between Queen Katharine and King Henry reached Charles from his ambassador in England. On the 13th of July Mendoza wrote from London that '... the king and his ministers were trying to dissolve the marriage between the queen and himself, alleging that the Pope had no power to grant a dispensation for the queen to marry two brothers as she had done.... The emperor may believe him (Mendoza) that there is so much feeling expressed here ... about the queen's divorce, not only on her own account, but because ... her daughter the princess would be declared illegitimate, that should six or seven thousand men land on the coast of Cornwall to espouse the cause of both mother and daughter, forty thousand Englishmen would at once join them....'[130] [130] _Calendar of Spanish State Papers._
