On the 14th of May 1780, the legislature of Virginia, in response to a petition of the inhabitants, declared that Connolly had forfeited his title, and incorporated the settlement under the name of Louisville, in recognition of the assistance given to the colonies in the War of Independence by Louis XVI.
At the outbreak of civil war in 1641, a conspiracy of the Irish septs, under the direction of Roger Moore, to seize Dublin Castle, was disclosed by one Owen Connolly on the eve of the day on which the attempt was to have been made, and the city was thus preserved for the king's party; but the Irish outside began an indiscriminate extermination of the Protestant population.
A year afterwards Fort Pitt was occupied by a company of Virginia soldiers by order of the Virginia Provincial Convention (assembled at Williamsburg in August 1775), but this move apparently was more for the defence of the frontier in the coming war than an expression on the Pennsylvania-Virginia boundary dispute; and, in November, Connolly was arrested at Fredericksburg, Maryland, on the charge of furthering Dunmore's plans for invading the western frontier.
The city of Louisville was laid out on the upper half of this Connolly tract.
In the following April Connolly took forcible possession of the court-house at Hanna's Town (near the present Greensburg), the county-seat of Westmoreland county (which then included the Fort Pitt region), a few days afterwards arrested the three justices who lived in Pittsburg, and for the remainder of the year terrorized the settlement.
