Forbes himself had arrived at Philadelphia early in April, to find that no army was ready for him. The Provincial troops allotted to him from Pennsylvania, Virginia, Maryland, and North Carolina had not even been enlisted; Montgomery's Highlanders were in the south, and only half of Colonel Bouquet's battalion of the Sixtieth was within reach. It was the end of June before the various fractions of his force were on march: and meanwhile the General was seized with a dangerous and agonising internal disease, against which he fought with a courage and resolution which was as admirable as it was pathetic. Forbes's career had been somewhat singular. He hailed from county Fife and had begun life as a medical student, but had entered the Scots Greys as a cornet and had risen to command the regiment. He had served in Flanders and Germany on the staff of Stair, Ligonier, and General Campbell, and finally as Cumberland's quartermaster-general.[292] But though all his training had been in the old formal school he had recognised, as has been seen, that in America he must learn a new art of war. He had studied Braddock's failure, and had perceived that even if Braddock had succeeded he must inevitably have retired from Fort Duquêsne from want of supplies. Instead, therefore, of making one long march with an unmanageable train of waggons, he decided to advance by short stages, establishing fortified magazines at every forty miles, and at last, when within reach of his destination, to march upon it with his entire force and with as few encumbrances as possible. This plan he had learned from a French treatise,[293] though he might have gathered it from a study of Monk's campaign in the Highlands had the opportunity been open to him. Nor was Bouquet, a Swiss by nationality, less assiduous in thinking out new methods. His views as to equipment have already been noticed; but knowing the value of marksmanship in the woods, Bouquet obtained a certain number of rifled carbines for his own battalion, and thus turned a part of the Sixtieth into Riflemen before their time.[294] He also introduced a new system of drill for work in the forest, forming his men into small columns of two abreast which could deploy into line in two minutes. Under such commanders the mistakes of Braddock were not likely to be repeated.[295] [Sidenote: July.]
