The following is a copy of Major McDonald’s report of the action, written on the spot, to Major-General Sir Denis Pack, K.C.B.— “SIR, “Colonel Cameron and Lieut.-Colonel Mitchell having been both severely wounded, I have the honor to report, for your information, (not having been under your eye during the whole of the day,) that the NINETY-SECOND regiment repulsed repeated attacks of cavalry, and by a rapid movement charged a column of the enemy, and drove them to the extremity of the wood on our right. “Our loss has been severe, as will be seen by the return of killed and wounded. “I have, &c., (Signed) “DONALD MCDONALD, “_Major 92nd, Commanding_. “Major-General Sir Denis Pack, K.C.B.” The Prussians had been attacked on the 16th of June at Ligny, and were forced to retreat to Wavre, and the Duke of Wellington made a corresponding movement to keep up his communication with them. In the course of the morning of the 17th of June, the troops were withdrawn from Quatre Bras, and the regiment was directed to form the rear-guard of the infantry, until it occupied its position in front of _Waterloo_, at a place named Mont St. Jean, where it arrived without being molested by the enemy. At the beginning of the memorable battle of Waterloo, which commenced about ten o’clock in the morning of the 18th of June, the NINETY-SECOND regiment, under the command of Major McDonald, with the rest of Sir Denis Pack’s brigade, was placed in support of some Belgian troops on the left of the main road to Brussels, and throughout the day was exposed to the fire of the enemy’s artillery and sharpshooters. The allied troops to the right having repulsed the repeated attacks in that quarter, the enemy directed his attention in a more particular manner to this part of the British line; and after having succeeded in carrying the farm-house of _La Haye Sainte_, under a most tremendous fire of artillery, he drove the Belgians from their post, and established himself in that part of the position. The moment the Belgians were seen running past the regiment to the rear, the third battalion of the Royals, and the second battalion of the forty-fourth regiment on its right in brigade, moved to the point which had thus been abandoned, and for some time maintained their ground in a manner becoming British soldiers, although ultimately obliged to give way. The NINETY-SECOND at this time was reduced to less than three hundred men. A column of three thousand French was formed in the position in front of the regiment, which was concealed by the nature of the ground. The French Commander having possessed himself of so advantageous a post, and seeing the troops give way, considered everything gained, and ordered arms.
