The army marched in column, three abreast, the various clans holding together under their own chiefs. Two miles short of Prestonpans Lord George learned the position of Cope's army, and at once led his light-footed soldiers up the slopes that commanded the plain. The English general was hourly expecting to see his enemies approach from the west by the road, and he was fully prepared to meet them at that point. At two in the afternoon, to his amazement, they suddenly appeared from the south, marching over the ridge of the hill.
The Hanoverian soldiers had enough spirit to receive them with cheers, to which the Highlanders responded by wild yells. They longed ardently to sweep down the slope and give instant battle, but the nature of the ground made this impossible even to a Highland army. Intersecting the hillside were high stone walls, which would have to be scaled under a hot fire from below, and at the bottom was a swamp, a wide ditch, and a high hedge. A certain gentleman in the Prince's army--Mr. Ker of Gordon--rode over the ground on his pony to examine its possibilities. He went to work as coolly as if he were on the hunting-field, making breaches in the wall and leading his pony through, in spite of a dropping fire from the Hanoverians. He reported that to charge over such ground was impossible. The Highlanders were bitterly disappointed; their one fear was that Cope should again slip away under cover of darkness. To prevent this Lord Nairne and 600 Perthshire men were sent to guard the road to Edinburgh. Seeing that nothing more could be done that night, both armies settled down to rest; General Cope lay in comfort at Cockenzie, Prince Charles on the field; a bundle of peastraw served for his pillow; a long white cloak thrown over his plaid for a covering.
Among the volunteers who had recently joined the Prince was an East Lothian laird called Anderson. He had often shot over the fields about Prestonpans. During the night he suddenly remembered a path which led from the heights, down through the morass on to the plain, slightly to the east of Cope's army. He sought out Lord George and told him of this path, and he, struck with the possibility of making immediate use of the information, took him without delay to the Prince. Charles was alert on the instant, entered into the plan proposed, and the next moment the word of command was passed along the sleeping lines. A few moments later the whole army was moving along the ridge in the dim starlight. But here a difficulty occurred. At Bannockburn, and in all great battles afterwards, except Killiekrankie, the Macdonalds had held the place of honour on the right wing of the army. They claimed that position now with haughty tenacity. The other clans, equally brave and equally proud, disputed the claim. It was decided to draw lots to settle the question. Lots were drawn, and the place of honour fell to the Camerons and Stewarts. An ominous cloud gathered on the brows of the Macdonald chiefs, but Locheil, as sagacious as he was courteous, induced the other chiefs to waive their right, and, well content, the clan Macdonald marched on in the van.
