Had Bishop Stephen Gardiner, ambassador to King Francis in Paris, not kept this letter, there would be no mention from Thomas Cromwell about the case against Anne Boleyn and her co-conspirators in 1536. Cromwell writes to tell Gardiner and his secretary Sir John Wallop about Anne’s crimes and a threat against the King’s life, leaving out all details. Cromwell also promises money to Gardiner, which came from the money collected from the men owed to the king.. Europe needed to know that Anne Boleyn had sinned against the king so much that serious action was taken for the king’s protection. Neither Cromwell nor anyone else believed in the case, and no one else in Europe ever seemed to take the case seriously either, but happily accepted Jane Seymour as queen a few weeks later.
Nothing about the case against Anne survives, none of Cromwell’s handwriting appears anywhere on the topic, except for his signature at the bottom of this letter. Cromwell did not take part in any of the trials or attend anything to do with the king’s new marriage. See Planning the Murder of Anne Boleyn for all the details.

THOMAS CROMWELL TO STEPHEN GARDINER AND JOHN WALLOP, 14 May 1536
(Add. MSS. 25,114, f. 160)
To myn Assured Loving friends my lord of Winchestre and S John Wallop knight the King Ambassadors in Fraunce in hast post
After my right hearty commendations, albeit you shall at this time receive no answer to your letters sent by Salisbury, being the same deferred till the arrival of the bailiff of Troyes, yet the king’s highness thought convenient that I should advertise you of a chance, as most detestably and abominably devised, contrived, imagined done and continued, so most happily and graciously by the ordinance of God revelled, manifested, and notoriously known to all men.
Whereof, though you have heard, I doubt not, the rumour, yet I shall express to you some pain of the coming out, and of the king preceding in the same. The queen’s abomination both in incontinent living, and other offences towards the king’s highness was so rank and common, that her ladies of her privy chamber and her chambers could not contain it within their breasts. But detesting the same had so often continuations and conference of it, that at the last it came so plainly to the cares of some of his grace’s council that, with their duty to his Majesty, they could not conceal it from him, but with great fear, as the case enforced declared what they heard to his highness.
Whereupon, in most secret sort, certain persons of the privy chamber and others of her side were examined, in which examinations the matter appeared so evident, that beside that crime, with the accidents, there broke out a certain conspiracy of the king’s death, which extended so far that all we that had the examination of it quaked at the danger his Grace was in, and on our knees gave Him laude and praise that He had preserved him so long from it, and now manifested the most wretched and detestable determination of the same.
Thus, were certain men committed to the Tower for this cause, that is Mark (Smeaton) and (Henry) Norris, and her brother (George). Then was she apprehended, and conveyed to the same place, after her was sent thither for the crimes specified, Sir Francis Weston and William Brereton. And Norris, Weston, Brereton, and Mark be already condemned to death, upon arraignment in Westminster Hall on Friday last. She and her brother shall be arraigned tomorrow and will undoubtedly go the same way.
I write no particularities, the things be so abominable, that I think the like was never heard, and therefore I doubt not but this shall be sufficient for your instruction to declare the truth if you have occasion so to do. Your lordship shall get in 200 pounds (around £120,000 today) of the 300 pounds that were out amongst these men, notwithstanding great suit has been made for the whole, which though the king’s highness might give in this case, yet his Majesty does not forget your service. And the third 100 pounds is bestowed of the vicar of hell (Francis Bryan), upon whom though it be some charge to you, his highness trusts you will think it well bestowed. And thus, fare you most heartily well from the (Chancery of the) Rolls in haste, this 14th of May
Your loving assured friend
THOMAS CRUMWELL
And you, Master Wallop, shall not at this time be forgotten, but the certainty of that you shall have I cannot tell, but in the next letters you shall know it, and I assure you the king’s highness takes both your services in as thankful part as yourself could wish or devise.
