Ar 12 Hydref cyflawnwyd gweithred anllad pan losgwyd fferm Penllwynys, ger Llanddarog, cartref Mr Thomas. Cynwyd swm enfawr o ŷd, a phe na bai'r gymdogaeth leol wedi ymdrechu i ddiffodd y tân, byddai'r eiddo i gyd wedi'i ddinistrio.
Ar yr un noson, ymosodwyd ar dŷ Mr. R. P. Beynon, Sanclêr, un o ynadon y sir.

Adysgrif:
"Carmarthen, 21 October, 1843.
Sir, Circular.
I request you assemble the Gentlemen who act as Magistrates in the Petty Sessions over which you preside, with as little delay as possible, and to inform them that Police Constables and Military are now distributed over the County, so as to give them every facility towards restoring peace and order.
I wish you to inform the Magistrates of your district that the Police stationed in it are placed at their disposal, and have orders to obtain every information in their power as to what may be going on in it; and that if they are in want of any assistance from a Magistrate they are to apply at the Cross Hands, Pontardulais, Lanon, and Gellywednen, to Mr. Nevill at Pontyberem, to yourself or some one at Llanlley, and Llanelly the same, and at Kidwelly and Trimsaran, Mr. Hugh Rees.
The troops are placed in their present position to afford assistance and support to the civil power, and whenever it becomes necessary to call on them to act they must be attended by a Magistrate, excepting when the Constables are placed in a situation of danger in the excution of their duty, which on such an emergency occuring or on any attack being made upon them, the Military will afford them the aid without waiting for the order or presence of a Magistrate.
These means of restoring peace and preventing outrage having been placed at the disposal of the Magistrates, I venture to express a confident hope that by their zeal and personal exertions on all necessary occasions they will controul and put down the spirit of insubordination and resistance to the Law which have so long prevailed in the County.
I have received the express order of the Secretary of State to impress as strongly as I am able upon the minds of the Magistracy of the County the necessity of their using every means in their power towards the attainment of that and
I am, Sir, yours obediently, Geo. Rice Trevor, Vice-Lt."
