Among the leaders of this great army were the Earls of Gloucester, Pembroke, Hereford, and Angus, Lord Clifford, Sir John Comyn, Sir Henry Beaumont, Sir John Seagrave, Sir Edmund Morley, Sir Ingram de Umfraville, Sir Marmaduke de Twenge, and Sir Giles de Argentine, one of the most famous of the Continental knights.
While this vast army had been preparing, Bruce had made every effort to meet the storm, and all who were loyal and who were able to carry weapons were summoned to meet at Torwood, near Stirling, previous to the 24th of June. Here Edward Bruce, Sir James Douglas, Randolph, Earl of Moray, Walter the Steward, Angus of Isla, Sir Archibald Forbes, and a few other knights and barons assembled with 30,000 fighting men, besides camp followers and servants. It was a small force indeed to meet the great army which was advancing against it, and in cavalry in particular it was extremely weak. The English army crossed the Border, and marched by Linlithgow and Falkirk toward the Torwood.
Each army had stirring memories to inspire it, for the English in their march crossed over the field of Falkirk, where sixteen years before they had crushed the stubborn squares of Wallace; while from the spot which Bruce selected as his battleground could be seen the Abbey Craig, overlooking the scene of the Scottish victory of Stirling Bridge. On the approach of the English the Scotch fell back from the Torwood to some high ground near Stirling now called the New Park. The lower ground, now rich agricultural land called the Carse, was then wholly swamp. Had it not been so, the position now taken up by Bruce would have laid the road to Stirling open to the English.
The Scotch army was divided into four divisions. The centre was commanded by Randolph. Edward Bruce commanded the second, which formed the right wing. Walter the Steward commanded the left wing, under the guidance of Douglas, while the king himself took command of the fourth division, which formed the reserve, and was stationed in rear of the centre in readiness to move to the assistance of either of the other divisions which might be hard pressed. The camp followers, with the baggage and provisions, were stationed behind the Gillies Hill.
The road by which the English would advance was the old Roman causeway running nearly north and south. The Bannock Burn was fordable from a spot near the Park Mill down to the village of Bannockburn. Above, the banks were too high and steep to be passed; while below, where ran the Bannock through the carse, the swamps prevented passage. The army was therefore drawn up, with its left resting on the sharp angle of the burn above the Park Mill, and extended where the villages of Easterton, Borestine, and Braehead now stand to the spot where the road crosses the river at the village of Bannockburn. In its front, between it and the river, were two bogs, known as Halberts Bog and Milton Bog, while, where unprotected by these bogs, the whole ground was studded with deep pits; in these stakes were inserted, and they were then covered with branches and grass. Randolph's centre was at Borestine, Bruce's reserve a little behind, and the rock in which his flagstaff was placed during the battle is still to be seen. To Randolph, in addition to his command of the centre division, was committed the trust of preventing any body of English from passing along at the edge of the carse, and so making round to the relief of Stirling.
On the morning of Sunday, the 23d of June, immediately after sunrise, the Scotch attended mass, and confessed as men who had devoted themselves to death. The king, having surveyed the field, caused a proclamation to be made that whosoever felt himself unequal to take part in the battle was at liberty to withdraw. Then, knowing from his scouts that the enemy had passed the night at Falkirk, six or seven miles off, he sent out Sir James Douglas and Sir Robert Keith with a party of horsemen to reconnoitre the advance.
The knights had not gone far when they saw the great army advancing, with the sun shining bright on innumerable standards and pennons, and glistening from lance head, spear, and armour. So grand and terrible was the appearance of the army that upon receiving the report of Douglas and Keith the king thought it prudent to conceal its full extent, and caused it to be bruited abroad that the enemy, although numerous, was approaching in a disorderly manner.
The experienced generals of King Edward now determined upon making an attempt to relieve Stirling Castle without fighting a pitched battle upon ground chosen by the enemy. Had this attempt been successful, the great army, instead of being obliged to cross a rapid stream and attack an enemy posted behind morasses, would have been free to operate as it chose, to have advanced against the strongholds which had been captured by the Scots, and to force Bruce to give battle upon ground of their choosing. Lord Clifford was therefore despatched with 800 picked men-at-arms to cross the Bannock beyond the left wing of the Scottish army, to make their way across the carse, and so to reach Stirling. The ground was, indeed, impassable for a large army; but the troops took with them faggots and beams, by which they could make a passage across the deeper parts of the swamp and bridge the little streams which meandered through it.
As there was no prospect of an immediate engagement, Randolph, Douglas, and the king had left their respective divisions, and had taken up their positions at the village of St. Ninians, on high ground behind the army, whence they could have a clear view of the approaching English army. Archie Forbes had accompanied Randolph, to whose division he, with his retainers, was attached. Randolph had with him 500 pikemen, whom he had withdrawn from his division in order to carry out his appointed task of seeing that the English did not pass along the low ground at the edge of the carse behind St. Ninians to the relief of Stirling; but so absorbed were knights and men-at-arms in watching the magnificent array advancing against the Scottish position that they forgot to keep a watch over the low ground. Suddenly one of the men, who had straggled away into the village, ran up with the startling news that a large party of English horse had crossed the corner of the carse, and had already reached the low ground beyond the church.
"A rose has fallen from your chaplet, Randolph," the king said angrily.
