Anfonwyd y llythyr hwn gan Rees Goring Thomas at William Chambers, ac mae'n ymwneud â'r ymosodiad diweddar gan ddilynwyr Beca ar Gelliwernen, Llan-non, sef cartref John Edwards, asiant Rees Goring Thomas. Roedd Goring Thomas yn gyfrifol am gasglu'r taliadau degwm yn y plwyf.

Disgrifiad gan Evan D. Jones:

'He regretted that any annoyance should have been caused to him in reference to his visit to Gellywernen with the soldiers. He would not have asked him to undertake that duty but would have done it himself had not Col. Trevor requested him to remain at Llysnewydd and advised him not to order soldiers to act in defence of his own property. He never heard Edwards make any complaint against the recipient. He spoke very gratefully of what he had done for him. He said the soldiers talked more than they should but no censure could attach to him or to Capt. Scott.

A Postscript: He had done good service at Hendy and Pontardulais.'
