About 2½ miles south of Stirling a small stream, the Bannockburn, flows from west to east, and then curving northwards flows into the Forth. Between it and Stirling lay the king's park, in which the Scottish army camped. The position chosen for receiving battle was immediately behind this stream. Bruce, who was comparatively weak in horsemen, had to depend, like Wallace, mainly on his spearmen for receiving the charge of the English men-at-arms. Barbour's long-winded poem on the life and acts of Robert Bruce, from which is derived the traditional account of the battle, contains sundry picturesque incidents, the truth of which need not be doubted, though he indulges in a vast amount of patriotic exaggeration. He does not, however, give the details in a form which renders the battle really intelligible. For instance, he describes minutely the "pots," round holes a foot broad and as deep as a man's knee, covered over with sticks and grass all green, which were intended to break the charge of the English horse. But he does not say where, relatively to the army, these pots were: nor does he mention them as having answered their purpose. An English chronicler, Baker of Swinbrook, describes a ditch, three feet deep and wide, as having been dug along the whole front, and covered over with hurdles and grass, into which the first line of the English fell; and the confusion thus occasioned involved the defeat of the English. Neither refers to the burn as having been any obstacle; Barbour indeed mentions houses having been pulled down by the English, with the timbers of which they made bridges over certain pools, but he does not say where the pools were. It is possible that as the battle was fought at midsummer, and Barbour lays great stress on the intense heat, the marshy ground on the north of it was unusually dry and firm; otherwise it is not obvious why Bruce should have wanted either pots or ditch.
