Obituary
At Lyneham Court near Devizes, aged 84, Bryan Rumboll, esq.

In the year 1838 Mr Rumboll was a farmer in the parish of Lyneham, and a man of the name of Maskelyne¹ was in his employ. On the 17th of January in that year, Mr Rumboll was returning from Calne market, on horseback, in the evening, and in passing through a gate into his grounds, he was shot at by some person secreted close by, and wounded in the left arm. It had been snowing that afternoon, and footmarks of a very peculiar character were traced towards Lyneham. Maskelyne¹ was suspected, and taken into custody.

When apprehended, a gun and some slugs were found in his house, and his shoes were proved to correspond exactly with the footmarks near the scene of the affray. Evidence was given to the effect that the prisoner had been heard to say that Mr Rumboll was an “ill man,” and that he would not help him out of the ditch if he saw him there. Some prisoners in Marlborough gaol at the time the prisoner was committed for trial proved that Maskelyne¹ made several statements to the criminating himself.

At the trial, which, which took place in August 1838, before Mr. Baron Parke (now Lord Wensleydale), it was urged that there was no proof of the prisoner entertaining any malice towards Mr Rumboll; that the statements of the prisoners from Marlborough gaol ought not to be credited; and that the jury ought not to convict the prisoner on the simple evidence of the footmarks. The jury, however, consulted only a short time, and then returned a verdict of guilty.

After his sentence Maskelyne¹ confessed to his guilt, and he was executed at Devizes gaol; on Thursday September 6 1838, in the presence of nearly 20,000. The poor wretch was so agitated that he had to be assisted to the scaffold by the executioner. - Wiltshire Independent
