This victory opened the whole of Scotland to Montrose He occupied the capital, and marched forward to the border; not merely to complete the subjection of the southern provinces, but with the flattering hope of pouring his victorious army into England, and bringing to the support of Charles the sword of his paternal tribes.

Half a century before Montrose’s career, the state of the borders was such as might have enabled him easily to have accomplished his daring plan.  The marquis of Douglas, the earls of Hume, Roxburgh, Traquair, and Annandale, were all descended of mighty border chiefs, whose ancestors could, each of them, have led into the field a body of their own vassals, equal in numbers, and superior in discipline, to the army of Montrose.  But the military spirit of the borderers, and their attachment to their chiefs, had been much broken since the union of the crowns.  The disarming acts of James had been carried rigorously into execution, and the smaller proprietors, no longer feeling the necessity of protection from their chiefs in war, had aspired to independence, and embraced the tenets of the covenant.  Without imputing, with Wishart, absolute treachery to the border nobles, it may be allowed, that they looked with envy upon Montrose, and with dread and aversion upon his rapacious and disorderly forces.  Hence, had it been in their power, it might not have altogether suited their inclinations, to have brought the strength of the border lances to the support of the northern clans.  The once formidable name of Douglas still sufficed to raise some bands, by whom Montrose was joined, in his march down the Gala.  With these reinforcements, and with the remnant of his Highlanders (for a great number had returned home with Colkitto, to deposit their plunder, and provide for their families), Montrose after traversing the border, finally encamped upon the field of Philiphaugh.

The river Ettrick, immediately after its junction with the Yarrow, and previous to its falling into the Tweed, makes a large sweep to the southward, and winds almost beneath the lofty bank, on which the town of Selkirk stands; leaving, upon the northern side, a large and level plain, extending in an easterly direction, from a hill, covered with natural copse-wood, called the Harehead-wood, to the high ground which forms the banks of the Tweed, near Sunderland-hall.  This plain is called Philliphaugh:[A] it is about a mile and a half in length, and a quarter of a mile broad; and, being defended, to the northward, by the high hills which separate Tweed from Yarrow, by the river in front, and by the high grounds, already mentioned on each flank, it forms, at once, a convenient and a secure field of encampment.  On each flank Montrose threw up some trenches, which are still visible; and here he posted his infantry, amounting to about twelve or fifteen hundred men.  He himself took up his quarters in the burgh of Selkirk, and, with him, the cavalry, in number hardly one thousand, but respectable,
