Mackay, Aeneas; Pennsylvania Council ● Letter from Aeneas Mackay, Pittsburgh, to Gov. Penn. Since Conolly's return from Virginia, on the 28th of March, Pittsburgh has become a scene of confusion. Conolly arrested on the 24th of January, and in prison a few days, when he prevailed upon the Sheriff to let him out to see his friends, instead of returning to Jail, as he had promised, he assembled a party of armed men, who guarded him from Red Stone to the frontiers of Virginia. Conolly, on the 30th of March, read to the Militia, assembled at Fort Pitt, Letters from Lord Dunmore, approving his conduct, and promising him assistance. The men were assembled in obedience to Lord Dunmore's positive orders, to hear the Letters read. Connolly arrested the Sheriff the next day, by a King's Warrant, and has had, ever since, armed parties in pursuit of the Deputy Sheriff and the Constables, he is now in actual possession of the Fort, with a guard, invested with Civil and Military power to enforce the laws of Virginia -- Lord Dunmore has enclosed him Commissions to fill up, at his discretion, for Militia Officers.
