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

writing and dispatching this agreeable intelligence to the king. Such an
enemy was already within four miles of his camp.

Recalled by the danger of the cause of the Covenant, General David Lesly
came down from England, at the head of those iron squadrons, whose force

intercept the return of Montrose's Highlanders, and to force him to an
unequal combat Accordingly, he marched along the eastern coast, from
Berwick to Tranent; but there he suddenly altered his direction, and,
crossing through Mid-Lothian, turned again to the southward, and,
