“This, my dear colonel, is, on my honour, an account of the operations of the British brigade in major-general Leith’s corps at Busaco. It will be satisfactory to you to know that the information you received has been correct. The anonymous officer of the ninth regiment I do not know. There were several very capable of furnishing you with good information on the transactions of that day, not only as regarded their own immediate corps, but those around them. Colonel Waller I should consider excellent authority; that gallant officer must have been an eye-witness to all that passed in the divisions of Picton and Leith. I remember on our approach to the scene of confusion he delivered me a message from general Picton, intended for general Leith, at the time reconnoitring, to hasten our advance.” “_Government House, Devonport, Aug. 21, 1834._ “——The fact really is that both the eighth and ninth Portuguese regiments gave way that morning, and I am positive that I am not far wrong in saying, that there were not of Portuguese troops within my view, at the moment I wheeled the ninth regiment into line, one hundred men prepared either for attack or defence. Sir James Douglas partly admits that his wing was broken when he says that ‘if we were at any time _broken_ it was from the too ardent wish of a corps of boy recruits to close.’ Now it is perfectly clear that the wing of the regiment under Major Birmingham fled, from what that officer said to general Leith. Sir James Douglas states also that ‘no candid man will deny that he supported the royals and ninth regiment, though before that he says, that ‘by an oblique movement he joined in the charge.’ I might safely declare on oath that the Portuguese never shewed themselves beyond the ridge of the Sierra that morning. “Very faithfully yours, “JOHN CAMERON.” As these letters from general Cameron refer to some of marshal Beresford’s errors, as well as Mr. Robinson’s, an extract from a letter of colonel Thorne’s upon the same subject will not be misplaced here. _Colonel Thorne to colonel Napier._ “_Harborne Lodge, 28th Aug. 1834._
