"To battle, then!" exclaimed Arran, waving his truncheon. "God and St. Andrew are with us!"

By this time the whole Scottish army had defiled across the high Roman bridge of Esk, and formed in dense columns of horse, foot, and archers, as they advanced towards the foe, presenting a splendid array, with all their polished helmets and cuirasses shining in the sun—their many square, triangular, and swallow-tailed banners waving, and their tall, uplifted lances, eighteen feet in length, and not less than fifteen thousand in number, swaying heavily to and fro, like a field of giant corn, as the close ranks marched on shoulder to shoulder, until the whole thirty-six thousand men stood in firm order of battle on the plain beyond the hill of Inveresk, which overlooked their left flank, while the green upland slope of Fawside rose upon their right.

With the shrill fife, the rattling drum (or Almainie swesche, as the Scots named it), the droning bagpipe, the twanging bugle-horn, the kettle, the clashing cymbal, and the sharp brass trumpet, filling the air with harsh but martial music, the Scottish lines drew near the English; and then the shouts, the cheers, the war-cries (the slogan of the Lowlanders, the cathghairm of the Celts), by which the soldiers of hastily-collected levies usually encourage each other, or taunt the foe, began to load the air with a confusion of sounds, after the deep boom of the first English cannon from the green brow of Inveresk had pealed through the clear welkin, and made a ghastly lane amid the nearest close column of Scottish infantry, causing the silken banners to rustle, the ranks to swerve, and the tall ash spears to sway like a corn-field bending beneath a blast of wind; and then to heaven went up a louder and a deeper shout, as the ranks closed over the mangled dead, and the forward march went on.

The centre was led by the Regent Arran in person. It consisted of the hardy clans from Stathearn, with the flower of the Scottish infantry, the men of Lothian, of Kinross, and of Stirlingshire. With many barons, he had also at least eight hundred chosen citizens of Edinburgh, led by William Craik, their provost. In their centre, Dick Hackerston bore the "Blue Blanket," or ancient banner of the city—a great swallow-tailed pennon of azure silk, worked for the burgesses by Margaret of Oldenburg. Among the men of Strathearn were the MacNabs, in their red, glaring tartans; and amid them were twelve stately warriors, conspicuous in their long lurichs of steel. These were Ian Mion and his eleven brothers, the heroes of the savage story of Lochearn, and on their banner was painted a human head affrontée.

The right wing consisted of six thousand western Highlanders, and brave and hardy islesmen, inured to battle and to storm, under MacLeod, MacGregor, and Archibald Earl of Argyle, the regent's son-in-law. On both its flanks and rear this column was covered by artillery. The other divisions presented the aspect either of dull or uniform masses covered with shining steel or brown leather; but this displayed the varied tartans of many Celtic tribes; and from its marching masses, with the incessant brandishing of swords and round targets, rose the wildest and most tumultuary shouts and outcries.

The left division of the Scots consisted of ten thousand infantry of Fife, Mearn, and the eastern counties, led by Archibald Earl of Angus, flanked by culverins and light horse. In their centre there marched a singular force, consisting of more than a thousand Scottish monks, who had been drawn from their cloisters by a terror of the Reformation (which Henry had so roughly established in England) being spread into Scotland, if Somerset's expedition proved successful. They were clad in plain black armour, and wore white or grey surcoats with crosses on the breast and back, to distinguish them as Dominicans, Cistercians, or Franciscans; and in their centre waved a white silk banner, which had been consecrated with many solemn ceremonies by the abbot of Dunfermline, after it had been made by Mary of Lorraine and the Countesses of Yarrow and Arran. Thereon was depicted a female kneeling with dishevelled hair before a cross, and around her was the motto—

"Afflictæ Ecclesiæ ne Obliviscaris."

The great squares or close columns of Scottish infantry were formed in admirable order, but in the ancient and somewhat unwieldy fashion of their country. Drawn up shoulder to shoulder, each soldier carried his spear, which was six Scots ells (i.e. eighteen feet) in length, pointing to the front; the first rank knelt, the next stooped, the third stood erect; but all had their weapons levelled at three angles towards the foe; thus the Scots were "so completely defended by the close order in which they were formed, and by the length of their lances, that to charge them seemed to be as rash as to oppose your bare hands to a hedgehog's bristles."

Lances, two-handed swords, and daggers, with mauls and Jethart staves, were the arms of the cavalry, who were all in complete mail, except the Borderers, who were always lightly armed, and seldom wore more than a skull-cap and breastplate or splinted jack, with plate sleeves and gloves of steel. A few were armed with wheel-lock pistols, which were brought from Italy or Flanders; but in the art of war, in order, and, above all, in perfect obedience, as well as in the discipline of the Boulogners and the new fashion of weapons, arquebuse and culiver, by which their auxiliaries the foreign horse and foot were armed, the English on this day were every way superior to the Scots.
