Full of wrath, Sir William shook off the dust from his feet as a testimony against Exmouth, and departed for London, where he remained two or three days, and then returned to Canterbury.
There he speedily involved himself in difficulties by his exertions in favour of some smugglers. An action had taken place in July, 1833, between the revenue cutter Lively and the Admiral Hood, smuggler, near Goodwin Sands, and in the course of the flight of the latter vessel her crew were observed to throw overboard a great number of tubs, which on being picked up proved to contain spirits. The Admiral Hood was captured, but no contraband goods were found on board; and on the men being taken into custody, Tom presented himself as a witness before the magistrates, and swore most positively that he had seen the whole affair, and that no tubs had been thrown from the Admiral Hood; he further stated that he had observed those which had been picked up by the revenue officers floating about on the water many hours before the Admiral Hood came near the Goodwins. This was so diametrically opposed to the truth that a prosecution for perjury was resolved on, and he was indicted at the Maidstone Assizes on July 25th, 1833. It was then proved that Sir William, on the very day on which the action had taken place, Sunday, the 17th February, had been twenty-five miles distant at Boughton-under-Blean, near Canterbury, and at the very hour of the action had been at church there. A verdict of conviction followed, and Mr. Justice Park, the presiding judge, passed a sentence of imprisonment for three months, to be followed by seven years of transportation beyond the seas.
This having reached the ears of his relations in Cornwall, representations were made by them to the Home Secretary that he was insane, and he was transferred to a lunatic asylum at Barming Heath, where he remained for four years, but whence he still issued addresses to his adherents in Canterbury and interfered in the election of councillors. There he remained for five years, and then a determined effort was made by his father and friends, and by Sir Hussey Brian, to obtain his liberation, and Lord John Russell ordered his liberation. This was an electioneering manœuvre, and Lord John had some difficulty in justifying his conduct in the House when later taken to task for having set this madman free.
On quitting the asylum, Tom hoped to take up his residence with a Mr. G. Francis, with whom he had been on terms of intimacy before. But Mr. Francis was by this time disillusioned, and when the Knight of Malta presented himself before him armed with a new pair of pistols, he remonstrated with him, and ordered him to quit the house; when he went to a cottage hard by occupied by one Wills, who was completely the dupe of Tom, and a passionate agitator. Then he went to Bossenden Farm occupied by a person named Culver. He gave out that he was the true proprietor of many of the finest estates in Kent, but that he would not enter into possession for two years. In addition to his living upon and amongst the farmers, he induced many of them to give him large sums of money, promising that for every shilling lent he would return a pound; and that, when he was in full possession of his estates, all his followers should have land free from rent according to their deserts. These promises made many dupes, and enabled him to indulge in luxuries which excited the astonishment of those not acquainted with his resources, and made many believe that he was what he pretended to be—really a nobleman of large property. To keep up this notion he made presents to various individuals; thus, to a fellow who had been prosecuted by the Revenue, Courtenay gave two horses worth £40. He was fond of displaying himself in fantastic dresses; he allowed his hair and beard, that was coal-black, to grow long; and he taught his followers to roar his battle song, of which only a few verses can be given here:—
Hark! old England's pris'ners' groan—
'Tis a deep and mournful tone—
From oppression to be free,
And enjoy true liberty.
Chorus.
Britons must be—will be free;
Truth bears off the victory!
Lo! deliverance is at hand;
Courtenay's made a noble stand;
He the tyrants has arous'd—
He has freedom's cause espous'd,
Britons must be, etc.
Courtenay's cause is good, is just,
Safely we in him may trust:
Truth and virtue's on his side,
We will still in him confide.
