Yn fuan wedi gorymdaith y Siartwyr yng Nghasnewydd, daeth Charles Walters i sylw'r cyhoedd. Cafodd ei arestio ynghyd ag arweinydd y Siartwyr, John Frost, gan iddynt gael eu darganfod gyda'i gilydd yng nghartref John Partridge, argraffydd, ar 4 Tachwedd 1849 yn dilyn yr ymosodiad ar Westy'r Westgate. Yn ôl yr hanes, roedd y saer llongau ifanc hwn o Gas-gwent yn aelod blaenllaw o'r Siartwyr, a derbyniodd gryn sylw gan y cyhoedd gan iddo gael ei anfon i'r carchar yn Nhrefynwy gyda John Frost. Cafodd Walters ei gyhuddo o deyrnfradwriaeth; plediodd yn ddi-euog i'r cyhuddiad yn y lle cyntaf ond newidiodd ei ble yn ddiweddarach. Cafodd ei ddedfrydu i farwolaeth ond derbyniodd addewid bod gobaith i'r ddedfryd honno gael ei lleihau. Adysgrif: 'Monmouth Jail January 15th 1840 My Dearest Father and Mother I may well ex- claim - "with what unequal tempers are we framed" - I wrote to you requesting you not to write to me again, ever since I have been anxious- ly wishing to hear from you; I hope and trust you are all well. Believe me I am in a straight I hard- ly know how to act. as you will see by the public papers, my respected friend Mr Frost has by a corrupt and perjured Jury been found guilty. sorry am I that a man from Chepstow should have been on that Jury, and have acted so base a part, the Chepstowmen are John Richards, John Capel Smith, and Smith the coachmaker. Zephaniah Williams is also found guilty, I suppose a better husband, Father, or Master, never existed. I've heard this morning that the Jury intends to find Jones guilty and to request the Judge not to sum up the evidence. A more baser set of men never existed than those 318 who is impannelled as the Jury to try our cases. I've had a proposition made to me this morning by my attorney of ra- ther a perplexing nature and how to act on it it I hardly know. it is as follows. That the I should withdraw my plea and plead guilty to the charge of treason wherewith I am charged this arises from a proposition made to our attor- ney by the opposite party ...'
