At eleven o'clock the English army was seen approaching. It was formed in three lines, with cavalry on each wing, and two pieces of cannon between every two regiments of the first line. The battle began with an artillery duel, but in this the advantage was all on the side of the English, the number of their pieces and the skill of their gunners being greatly superior.
Prince Charles rode along the front line to animate his men, and as he did so several of his escort were killed by the English cannonade. A storm of snow and hail had set in, blowing full in the face of the Highlanders. At length Lord George Murray, finding that he was suffering heavily from the enemy's artillery fire, while his own guns inflicted but little damage upon them, sent to Prince Charles for permission to charge.
On receiving it he placed himself at the head of his men, and with the whole of the right wing and centre charged the enemy. They were received with a tremendous musketry fire, while the English artillery swept the ranks with grape; but so furious was their onslaught that they broke through Munro and Burrel's regiments in the first line and captured two pieces of cannon. But behind were the second line drawn up three deep, with the front rank kneeling, and these, reserving their fire until the Highlanders were close at hand, opened a rolling fire so sustained and heavy that the Highlanders were thrown into complete disorder.
Before they could recover themselves they were charged by horse and foot on both flanks, and driven together till they became a confused mass. In vain did their chiefs attempt to rally them. Exhausted and weakened in body, swept by the continuous fire of the English, they could do no more, and at last broke and fled. In the meantime the Macdonalds on the left remained inactive. In vain Lord John Drummond and the Duke of Perth called upon them to charge, in vain their chief, Keppoch, rushed forward with a few of his clansmen and died in front of them. Nothing would induce them to fight, and when the right and centre were defeated they fell back in good order, and, joining the remnants of the second line, retired from the field unbroken.
Charles, from the heights on which he stood with a squadron of horse, could scarce believe the evidence of his eyes when he saw the hitherto victorious Highlanders broken and defeated, and would have ridden down himself to share their fate had not O'Sullivan and Sheridan seized his horse by the bridle and forced him from the field. Being pressed by the English, the retreating force broke into two divisions. The smaller retreated to Inverness, where they next day laid down their arms to the Duke of Cumberland; the other, still preserving some sort of order, marched by way of Ruthven to Badenoch.
Fourteen colours, two thousand three hundred muskets, and all their cannon fell into the hands of the English. The loss of the victors in killed and wounded amounted to three hundred and ten men, that of the Highlanders to a thousand. No quarter was given to the stragglers and fugitives who fell into the hands of the English. Their wounded were left on the ground till the following day without care or food, and the greater portion of them were then put to death in cold blood, with a cruelty such as never before or since disgraced an English army.
Some were beaten to death by the soldiers with the stocks of their muskets, some were dragged out from the thicket or caverns to which they had crawled and shot, while one farm building, in which some twenty wounded men had taken refuge, was deliberately set on fire and burned with them to the ground. In any case such conduct as this would have inflicted eternal discredit upon those who perpetrated it; but it was all the more unjustifiable and abominable after the extreme clemency and kindness with which Prince Charles had, throughout the campaign, treated all prisoners who fell into his hands.
Ronald had ridden close beside Lord George Murray as he led the Highlanders to the charge; but he had, as they approached the first English line, received a ball in the shoulder, while almost at the same instant Malcolm's horse was shot under him. Ronald reeled in the saddle, and would have fallen had not Malcolm extricated himself from his fallen horse and run up to him.
"Where are you hit, lad?" he asked in extreme anxiety.
"In the shoulder, Malcolm. Help me off my horse, and do you take it and go on with the troops."
