Information having been received of the advance of the Highlanders to Derby, and of their precipitate retreat from thence towards Scotland, an attempt was made to intercept them, but without success. The FOURTH HORSE were subsequently despatched, with some other corps, under Major-General Oglethorp, in pursuit, and, after marching a distance of 100 miles in three days, in most inclement weather, and along roads choked with ice and snow, the King's troops overtook and defeated the rear of the rebel army on the borders of Lancashire, and captured several prisoners; but the main body of the Highlanders escaped, and, having placed a garrison in Carlisle, continued their flight to Scotland. The FOURTH HORSE pursued the Highlanders to Carlisle, and were stationed near that city until its surrender on the 30th of December. [Sidenote: 1746] In the beginning of 1746 the FOURTH HORSE marched to York, and, after the decisive overthrow of the rebel army at _Culloden_, the regiment furnished escorts to guard parties of prisoners to Lincoln, and other places, in which service it was partially engaged throughout the summer; and in September it was stationed at Bristol. The suppression of this rebellion having been effected, His Majesty resolved, as a measure of economy, to reduce this and two other regiments from the pay and quality of HORSE to that of DRAGOONS. The establishment was accordingly changed on the 25th of December, 1746, and, the pay of the non-commissioned officers and private men being reduced by this alteration, every man received a gratuity of three pounds, with the option of his discharge; and the men who accepted their discharge received fourteen days' pay each, to defray the expense of their journey home. The regiment was now armed with long muskets and bayonets, also with swords and pistols, as before. A slight alteration was at the same time made in the uniform;--the officers were distinguished by gold lace and embroidery on their regimentals, and a crimson silk sash worn over the left shoulder; the quarter-masters by gold lace, and silk sashes round their waists; and the serjeants by narrow lace on the lappels, sleeves, and pockets, and a worsted sash round the waist. When this change had taken place His Majesty conferred on the regiment the title of THIRD DRAGOON GUARDS, by a warrant dated the 9th of January, 1747, of which the following is a copy:-- [Sidenote: 1747] 'GEORGE R.
