However, it is known that both Muir's parents were orthodox Presbyterians, consequently young Thomas's early upbringing was very much within the confines of the rigid moral and social ethic of ‘Auld Licht’ Calvinism.
At the beginning of the new academic year Muir, with the assistance of Millar, obtained a place at Edinburgh University under the Whig Professor of Law, John Wylde.
An Elder of the Church of Scotland for his home parish of Cadder, Muir became embroiled at the beginning of 1790 in a dispute with the local landlords led by James Dunlop of Garnkirk, a rich owner.
In June 1792, the members of these societies and, in particular, those at Glasgow, Edinburgh, Dundee and Perth, began a regular correspondence with the object of forming a Scottish counterpart to the London Association.
Sharing their concern that the execution of Louis XVI would be a disaster for the reform movements in the British Isles, Muir agreed to go to France and join Tom Paine in his attempts to persuade the leaders of the revolution to spare the life of the King.
[4] On 21 November, Muir, having been elected vice-president of the movement at the Edinburgh monthly meeting, called for a General Convention of the popular reform societies in Great Britain to be held there in December.
With the outbreak of war with France the anti-reform party in Scotland became increasingly militant, and Dundas advanced the date of Muir's trial from April to 11 February.
[10] Urged on by the secretary of the society, Archibald Hamilton Rowan, Muir decided to ignore his father's advice to remain in exile, and to return to Scotland to face down his accusers.
Into this vacuum stepped three English delegates: Maurice Margarot, a merchant with a university education, Joseph Gerrald, friend and correspondent of William Godwin and an orator of flawless eloquence, and Matthew Campbell Browne, an actor turned reformer.
Where the English societies remained psychologically and geographically divided, the Scots had an unprecedented degree of national unity backed by the general sympathy of the common people.
What Muir thought of this reckless exposure to destruction of the organisation which he and William Skirving had so carefully nurtured is revealed by his description of it in 1797 as 'a miserable plaything of the English Government'.
Ultimately it was a motion of Charles Sinclair, delegate from the Society for Constitutional Information (London), which gave Dundas his much sought-for excuse to disperse the convention.
Early on the morning of 5 December arrest warrants were issued and served by armed bailiffs upon Skirving, Margarot, Gerrald, Sinclair and Matthew Campbell Browne.
After spending some time in Newgate Jail where they were joined by the newly convicted associates, Palmer, Skirving and Margarot, they were removed by coach to Portsmouth and placed aboard a new transport Surprize.
[12] In spite of belated and somewhat reluctant attempts on behalf of the Whigs in Parliament and the Lords to obtain a pardon for the radicals, they were abruptly shipped out for Botany Bay on the morning of 24 May.
[13][14] During the long voyage out to Australia an attempt was made (with or without official connivance) to discredit Muir, Skirving and Palmer by implicating them in an alleged mutiny led by the first mate.
This affair, however, was so badly bungled that, in spite of having to endure much harsh and brutal treatment at the hands of the captain, the reformers had little difficulty in refuting the evidence against them upon arrival at Port Jackson.
In November, Judge Advocate Collins records that: The Lieutenant-Governor having set apart for each of the gentlemen who came out from Scotland in the Surprise a brick hut, in a row on the east side of the cove, they took possession of their new habitations, and soon declared that they found sufficient reason for thinking "the bleak and desolate shores of New Holland " not quite so terrible as in England they had been led to expect.
Unlike his companions, or indeed his father, Muir had little or no taste for farming and with an eye to ultimate escape from the settlement, he purchased a small hut and several acres of land on the opposite side of the bay.
Early in 1796 with the assistance of Pierre François Péron, a French sailor, he succeeded in arranging his escape from the settlement on board the American maritime fur trade ship Otter, of Boston.
Only Margarot might have availed himself of Muir's plan; however he was absent at a farm deep in the hills at Parramatta, and in any case he had been sent to Coventry (i.e. exiled) by his former colleagues because of his part in supporting the mutiny allegations.
After a highly adventurous voyage across the as yet largely uncharted Pacific Ocean to Vancouver Island, Otter finally dropped anchor in Nootka Sound on 22 June 1796.
[15] In conversation with the Portuguese José Tovar, the piloto (master) of the Sutil, a Spanish vessel at anchor in the bay,[clarification needed] Muir learned to his dismay of the presence in neighbouring waters of HMS Providence, a British sloop-of-war under William Robert Broughton.
On arrival at this important Spanish outpost, Muir was introduced to the Governor, Don Diego Borica, who was favourably impressed by his character and intelligence, and allocated him accommodation along with his own family in the Presidio.
On the morning of 26 April 1797 as Muir's ship, the Ninfa, approached the entrance to Cadiz Harbour, he was confronted by several Royal Navy Men o' War who for some weeks had been blockading the port.
Now began a long and painful recovery, while the French and Spanish authorities, from Consular to Ambassadorial and ultimately at Ministerial level, indulged in a bitter diplomatic wrangle over Muir's release.
Still weak and emaciated from his sufferings, Muir made his way to France by way of Madrid and San Sebastian, aided and assisted by a young officer from the French Consulate at Cadiz.
Feted by the civic authorities and literary societies, his last portrait, commissioned for display in public buildings, shows him with a large black patch over his left eye.
When several days later the news of Muir's passing finally reached Paris, a brief obituary notice was inserted in le Moniteur universel to the effect that he had died from a recurrence of his old wounds.
After the destruction of so many years, we have been the first to revive the spirit of our country and give it a National Existence.Thomas Muir was the most important of the group of two Scotsmen and three Englishmen commemorated at the Political Martyrs' Monument the others being Thomas Fyshe Palmer, William Skirving, Maurice Margarot.
