Extract.—“Viscount Beresford in the ‘_Refutation of your Justification of your third volume_,’ has doubted the accuracy of the strength of the third dragoon guards and fourth dragoons on the 20th March 1811, as extracted by you from the journal which I lent to you. As I felt confident I had not inserted any thing therein, which I did not obtain from _official documents_, that were in my possession at the time it was written, I have, since the perusal of the ‘Refutation,’ looked over some of my Peninsula papers, and I am happy to say I have succeeded in finding amongst them, the monthly returns of quarters of the division of cavalry commanded by brigadier-general Long, dated Los Santos, April 20th, 1811, which was then sent to me by the deputy assistant quarter-master general of that division, and which I beg to enclose for your perusal, in order that you may see the statement I have made of the strength of that force in my journal _is to be relied upon, although his lordship insinuates to the contrary_, and that it contains _something more than_ ‘_the depositary of the rumours of a camp_.’” _Extract from memorandum of the battle of Busaco, by colonel Waller, assistant quarter-master-general to the second division._ “—The attack commenced on the right wing, consisting of Picton’s division, by the enemy opening a fire of artillery upon the right of the British which did but little injury, the range being too great to prove effective. At this moment were seen the heads of the several attacking columns, THREE, I THINK, in number, and deploying into line with the most beautiful precision, celerity, and gallantry. “As they formed on the plateau they were cannonaded from our position, and the regiment of Portuguese, either the eighth or the _16th Infantry_, which were formed in advance in _front_ of the _74th regiment_, threw in some volleys of musketry into the enemy’s columns in a flank direction, but the regiment was quickly driven into the position. “More _undaunted_ courage never was displayed by _French_ troops than on _this_ occasion: it could not have been surpassed, for their columns advanced in despite of a tremendous fire of grape and musketry from our troops in position in the rocks, and overcoming all opposition, although repeatedly charged by Lightburne’s brigade, or rather by the whole of Picton’s division, they advanced, and fairly drove the BRITISH RIGHT wing from the rocky part of the position.
