In March, 1529-30, the English ambassadors appeared at Bologna.  Their instructions were honest, manly, and straightforward.  They were directed to explain, ab initio, the grounds of the king’s proceedings, and to appeal to the emperor’s understanding of the obligations of princes.  Full restitution was to be offered of Catherine’s dowry, and the Earl of Wiltshire was provided with letters of credit adequate to the amount.[256] If these proposals were not accepted, they were to assume a more peremptory tone, and threaten the alienation of England; and if menaces were equally ineffectual, they were to declare that Henry, having done all which lay within his power to effect his purpose with the goodwill of his friends, since he could not do as he would, must now do as he could, and discharge his conscience.  If the emperor should pretend that he would “abide the law, and would defer to the pope,” they were to say, “that the sacking of Rome by the Spaniards and Germans had so discouraged the pope and cardinals, that they feared for body and goods,” and had ceased to be free agents; and concluding finally that the king would fear God rather than man, and would rely on comfort from the Saviour against those who abused their authority, they were then to withdraw.[257] The tone of the directions was not sanguine, and the political complications of Europe, on which the emperor’s reply must more or less have depended, were too involved to allow us to trace the influences which were likely to have weighed with him.  There seems no prima facie reason, however, why the attempt might not have been successful.  The revolutionary intrigues in England had decisively failed, and the natural sympathy of princes, and a desire to detach Henry from Francis, must have combined to recommend a return of the old cordiality which had so long existed between the sovereigns of England and Flanders.  But whatever was the cause, the opening interview assured the Earl of Wiltshire that he had nothing to look for.  He was received with distant courtesy; but Charles at once objected even to hearing his instructions, as an interested party.[258] The earl replied that he stood there, not as the father of the queen’s rival, but as the representative of his sovereign; but the objection declared the attitude which Charles was resolved to maintain, and which, in fact, he maintained throughout.  “The emperor,” wrote Lord Wiltshire to Henry, “is stiffly bent against your Grace’s matter, and is most earnest in it; while the pope is led by the emperor, and neither will nor dare displease him."[259] From that quarter, so long as parties remained in their existing attitude, there was no hope.  It seems to have been hinted, indeed, that if war broke out again between Charles and Francis, something might be done as the price of Henry’s surrendering the French alliance;[260] but the suggestion, if it was made, was probably ironical; and as Charles was unquestionably acting against his interest in rejecting the English overtures, it is fair to give him credit for having acted on this one occasion of his life, upon generous motives.  A respectful compliment was paid to his conduct by Henry himself in the reproaches which he addressed to the pope.[261]
