It was the 10th of November when Mar, aware that Argyll was advancing against him, at length marched out of Perth with all his baggage and provisions for twelve days. On the 12th, when they arrived at Ardoch, Argyll was posted at Dunblane, and he advanced to give them battle. The wild, uneven ground of Sheriffmuir lay between them, and it was on this spot that Argyll on quitting Stirling had hoped to meet them. He therefore drew up his men on this moorland in battle array, and did not wait long for the coming of the Highland army. It was on a Sunday morning, the 13th of November, that the battle of Sheriffmuir was fought. Argyll commanded the right wing of his army, General Whitham the left, and General Wightman the centre. He calculated much on this open ground for the operations of his cavalry. On the other hand, Mar took the right wing of his army, and was thus opposed, not to Argyll, but to Whitham. The Highlanders, though called on to form in a moment, as it were, did so with a rapidity which astonished the enemy. They opened fire on Argyll so instantly and well, that it took the duke's forces by surprise. The left army retired on Stirling pursued by Mar. Argyll was compelled to be on the alert. He observed that Mar had drawn out his forces so as to outflank him; but, casting his eye on a morass on his right, he discovered that the frost had made it passable, and he ordered Major Cathcart to lead a squadron of horse across it, while with the rest of his cavalry he galloped round, and thus attacked the left wing of Mar both in front and flank. The Highlanders, thus taken by surprise, were thrown into confusion, but still fought with their wonted bravery. They were driven, however, by the momentum of the English horse, backwards; and between the spot whence the attack commenced and the river Allan, three miles distant, they rallied ten times, and fairly contested the field. Argyll, however, bore down upon them with all the force of his right wing, offering quarter to all who would surrender, and even parrying blows from his own dragoons which went to exterminate those already wounded. After an obstinate fight of three hours, he drove the Highlanders over the Allan, a great number of them being drowned in it. Mar at this crisis returned to learn the fate of the rest of his army. He found that he had been taking the office of a General of Division instead of that of the Commander-in-Chief, whose duty is to watch the movements of the whole field, and send aid to quarters which are giving way. Like Prince Rupert, in his ardour for victory over his enemies in front of him, he had totally forgotten the centre and left wing, and discovered now that the left wing was totally defeated. He was contented to draw off, and yet boast of victory.
