Although the Highlanders marched on very fast, the sun was declining when they arrived upon the brow of those high grounds which command an open and extensive plain stretching northward to the sea, on which are situated, but at a considerable distance from each other, the small villages of Seaton and Cockenzie, and the larger one of Preston. One of the low coast-roads to Edinburgh passed through this plain, issuing upon it from the enclosures of Seaton-house, and at the town or village of Preston again entering the defiles of an enclosed country. By this way the English general had chosen to approach the metropolis, both as most commodious for his cavalry, and being probably of opinion that, by doing so, he would meet in front with the Highlanders advancing from Edinburgh in the opposite direction. In this he was mistaken; for the sound judgement of the Chevalier, or of those to whose advice he listened, left the direct passage free, but occupied the strong ground by which it was overlooked and commanded. When the Highlanders reached the heights above the plain described, they were immediately formed in army of battle along the brow of the hill. Almost at the same instant the van of the English appeared issuing from among the trees and enclosures of Seaton, with the purpose of occupying the level plain between the high ground and the sea; the space which divided the armies being only about half a mile in breadth. Waverley could plainly see the squadrons of dragoons issue, one after another, from the defiles, with their videttes in front, and form upon the plain, with their front opposed to that of the Prince's army. They were followed by a train of field-pieces, which, when they reached the flank of the dragoons, were also brought into line, and pointed against the heights. The march was continued by three or four regiments of infantry marching in open column, their fixed bayonets showing like successive hedges of steel, and their arms glancing like lightning, as, at a signal given, they also at once wheeled up, and were placed in direct opposition to the Highlanders. A second train of artillery, with another regiment of horse, closed the long march, and formed on the left flank of the infantry, the whole line facing southward.
