At two o'clock on the morning of the 11th of May, the allied army advanced to attack the formidable position occupied by the enemy, and the Twelfth regiment, commanded by Colonel Duroure, was detached with several other corps, under Brigadier-General Ingoldsby, to attack a large fort, mounted with cannon, in the wood of Barri. Against this post the regiment advanced, but the fort was found too formidable to be attacked without artillery, and some delay occurred. Brigadier-General Ingoldsby did not clearly understand his orders, and the regiment was detained a long time in a state of inactivity exposed to a heavy cannonade; during which time the British infantry had forced the enemy's centre, but were obliged to retire in consequence of the Dutch having failed on Fontenoy, and Brigadier-General Ingoldsby having lost the opportunity of attacking the batteries in the wood of Barri. A second attack was, however, determined on, in the hope that the Dutch would make a more determined effort, and the Twelfth were brought into action; Brigadier-General Ingoldsby was wounded at the head of the regiment, and removed to the rear. Impatient of the state of inactivity in which they had been detained, the soldiers of the Twelfth rushed into action with distinguished ardour, and were conspicuous for their gallant bearing throughout the remainder of the contest. They were exposed to a heavy fire, and had to contend against very superior numbers. Their commanding officer, Colonel Duroure, fell mortally wounded; Lieut.-Colonel Whitmore was killed; Major Cosseley was wounded, and the command devolved on Captain Rainsford, who was also wounded: but the regiment preserved its firm array, and when more than half the non-commissioned officers and soldiers had fallen, the survivors continued the fight, advancing over the killed and wounded of both armies. The Dutch, however, failed a second time; the British who had penetrated the enemy's line became insulated, and constantly exposed to the attack of fresh troops, and a retreat was ordered; the army withdrawing from the field of battle to Aeth.
The conduct of the Twelfth regiment was commended in the Duke of Cumberland's public despatch; its loss was greater than any other corps in the army, and amounted to three hundred and twenty-one officers and soldiers: viz., Lieut.-Colonel Whitmore, Captain Campbell, Lieutenants Bockland and Lane, Ensigns Cannon and Clifton, five serjeants, and one hundred and forty-eight rank and file killed; Colonel Duroure, Major Cosseley, Captains Rainsford and Robinson, Lieutenants Murray, Townshend, Millington, and Delgaire, Ensigns Dagers and Pearce, seven serjeants, and one hundred and forty-two private soldiers wounded; Captain de Cosne, Captain-Lieut. Goulston, and Lieut. Salt, missing.
Colonel Duroure died of his wounds, and was succeeded by Brigadier-General Henry Skelton, from the thirty-second regiment of foot. Major Cosseley recovered of his wounds, and was promoted to the lieut.-colonelcy, and Captain Rainsford was appointed Major.
The regiment was encamped with the army on the plain of Lessines, and afterwards near Brussels; and the French, by their superior numbers, were enabled to capture several fortified towns.
In the meantime a rebellion had broken out in Scotland, headed by Charles Edward, eldest son of the Pretender. This adventurer, being guided by desperate and designing men,—urged on by the wily politics of France,—personally sanguine in his disposition, and disposed to listen to every representation that flattered his views, embarked on his expedition in a style little adequate to the extent of his designs, which were to dethrone the reigning monarch, and to overturn the constitution of a brave and free people. Arriving in Scotland, he was joined by several of the Highland clans, and the King's troops being in Flanders, success attended his efforts for a short period.
The Twelfth regiment was one of the corps ordered to return to England on this occasion: it arrived at Gravesend on the 4th of November, afterwards formed part of the army assembled under the Duke of Cumberland, when the clans penetrated England as far as Derby.
Being little accustomed to hear the sound of war at their own gates, the British were at first alarmed at the novelty; but soon recovering, they evinced loyalty and union in sustaining the fixed rights of their sovereign, and in defending their own liberties. Addresses, backed by associations, were daily made to the King; the army arrived from Flanders, and the Pretender made a precipitate retreat back to Scotland.
The Twelfth regiment pursued the Highlanders as far as Carlisle, and was before that town when the rebel garrison surrendered.
1746
In the early part of 1746 the regiment was withdrawn from the north of England; but after the loss of the battle of Falkirk by the troops under Lieut.-General Hawley, it was ordered to proceed to Scotland. Various circumstances occurred to prevent its proceeding thither immediately; but it embarked from Plymouth towards the end of March, and sailed for Scotland in the early part of April.
