In the second siege, on the night before the storming, sergeant William Rogers, and three intrepid men of the corps, accompanied Captain Patton, R.E., on the dangerous service of reconnoitring the fords of the Rivillas, and the approach to the castle breach beyond the river. They conducted the examination for a time and then returned to the works for a file of men as a guard. With this escort they retraced their steps; but left it behind at a short distance from the breach, when the captain and his “trusty sergeant” went forward alone and completed the reconnaissance. In returning to the guard the captain stumbled, and the clanking of his sword drawing the attention of the French sentinels, they fired, and he fell mortally wounded. Sergeant Rogers protected his captain till he gained the escort, with whose assistance he succeeded in bearing him alive to the trenches. Captain Patton was able to make his report of the practicability of the assault and soon afterwards expired.[169] Sergeant Rogers died at Fuente Guinaldo in the following August. Of him Colonel Fletcher wrote: “he was an attentive, good soldier, and in every way a most estimable character.” ----- Footnote 169: Jones’s ‘Sieges,’ vol. i., p. 70, 2nd edit. ‘United Service Journal,’ ii., 1831, p. 331. ----- In May the detachment under Lieutenant-Colonel Fletcher received an addition of thirty-nine men; and on the 29th June a further reinforcement of sixty-three non-commissioned officers and men under Lieutenants Melhuish and De Salaberry, royal engineers. In consequence of this augmentation, the men of the infantry acting as overseers and mechanics on the lines, rejoined their respective regiments; and the posts thus vacated were occupied by the newly-arrived detachments of military artificers.[170] ----- Footnote 170: Jones’s ‘Sieges,’ vol. i., p. 90, 2nd edit. ----- The whole force of the corps in Portugal amounted in July to 8 sergeants, 5 corporals, 16 second corporals, 3 drummers, and 145 privates; total, 177. Of this number a comparatively small party only was kept with the army, whilst the remainder were distributed to the lines, Sobral, Oeyras, the Almada position, Peniche, Abrantes, Alhandra, Fort St. Julian, &c. In conducting the works at those places, “the abilities and good conduct of the men were found of the utmost advantage.” At Fort St. Julian particularly, where they were employed in the formation of four extensive jetties for the embarkation of troops in case of necessity, their skill and expertness were found of great importance. Sergeant John M‘Kay had the executive superintendence of the work under the direction of Captain Holloway, R.E. The detachment with the moving army was broken up into sections of five or six men to each division or corps, and one or other of them was at the blockade of Almeida, Fuentes d’Onoro, Albuera, Campo Maior, and the several other actions which occurred in the Peninsula during the campaign of 1811.
