Eyre's policy was supported by the government, but opposed by the Corporation of Galway, the Prime Sergeant, the Protestant
Bishop of Elphin, and
Francis II de Bermingham, Lord Athenry. He was threatened with assassination as would appear from the following anonymous letter which he enclosed with his correspondence to Secretary Wayte, 11 December 1747:- ''Sir, as I had not the pleasure of seeing you since you came to your government of Galway, I hope soon to see you in the Elysian fields, as I am just going off the stage. And I am sure, if you don't leave that town, you'll lose your life before the 10th of next month. 'Tis all your own fault, for you could not bear the employment which you got, not for your bravery, but for the slaughter you committed on poor people after Culloden fight. You'll be served as Lord Lovat's agent was. God be merciful to your soul.'' Much of the dissent centred on Robert Martin of Dangan, the leader of the Connacht
Jacobites and a leading
Freemason. Thady Brennan, Martin's servant, walked past the sentinel at the bridge carrying a gun and pistol, apparently for repair. The boy being a Catholic was disarmed, but Eyre returned the weapons to Martin with a message that if he was sending arms into the town he had better in future send them by persons qualified to carry such things. On Martin refusing to receive back his property, Eyre confiscated the weapons. The assizes coming on Martin served a summons on Eyre to appear before the judges and answer to a charge of larceny. Enclosing the following document to Secretary Wayte, Eyre wrote,
"If the law was to be thus openly insulted, government would become impossible and neither the Property Act nor any other act, could be enforced in any part of Ireland." Eyre travelled to London on business, where he was followed and struck by Robert Martin. The two engaged in a lengthy sword-duel, with Martin emerging the winner. The two would remain antagonists, as Martin continued to recruit for Jacobite regiments in France, and is believed to have harboured
Bonnie Prince Charlie on an incognito visit to Ireland in 1753. Froude described Eyre as
"a man full of violent personal and religious animosities, intolerant of opposition, and much more fit of the command of a regiment than for the difficult task of governing a Catholic town." His descendants continued to live in the county into the late 19th century. ==Note==
