For some years after Braddock's defeat his route to and fro between the Monongahela and Potomac was used only by scouting parties of whites and marauding Indians, and many were the swift encounters that took place upon its overgrown narrow track. In 1758 General Forbes built a new road westward from Carlisle, Pennsylvania rather than follow Braddock's ill-starred track, for reasons described in another volume of the present series.[52] Forbes frightened the French forever from the "Forks of the Ohio" and erected Fort Pitt on the ruins of the old Fort Duquesne. In 1763 Colonel Bouquet led a second army across the Alleghenies, on Forbes's Road, relieved Fort Pitt and put an end to Pontiac's Rebellion. By the time of Forbes's expedition Braddock's Road was somewhat filled with undergrowth, and was not cut at all through the last and most important eight miles of the course to Fort Duquesne. Forbes had some plans of using this route, "if only as a blind," but finally his whole force proceeded over a new road. However, certain portions of Braddock's Road had been cleared early in the campaign when Forbes thought it would be as well to have "two Strings to one Bow." It was not in bad condition.[53] This new northern route, through Lancaster, Carlisle, Bedford (Reastown), and Ligonier, Pennsylvania, became as important, if not more so, than Braddock's course from Cumberland to Braddock, Pennsylvania. As the years passed Braddock's Road seems to have regained something of its early prestige, and throughout the Revolutionary period it was perhaps of equal consequence with any route toward the Ohio, especially because of Virginia's interest in and jealousy of the territory about Pittsburg. When, shortly after the close of the Revolution, the great flood of immigration swept westward, the current was divided into three streams near the Potomac; one went southward over the Virginian route through Cumberland Gap to Kentucky; the other two burst over Forbes's and Braddock's Roads. Some pictures of the latter are vividly presented in early records of pilgrims who chose its rough path to gain the El Dorado beyond the Appalachian mountain barriers. William Brown, an emigrant to Kentucky from Hanover, Virginia, over Braddock's Road in 1790 has left a valuable itinerary of his journey, together with interesting notes, entitled _Observances and Occurrences_. The itinerary is as follows:
