Cameron and his Highlanders endured great misery on the disastrous retreat from Burgos. Deprivation of food reduced the poor men almost to skeletons; their uniform was worn to rags; many were barefooted, and shirtless. Undeterred by the cruel exhibition of a soldier hung _daily_ at the head of the column (for of twenty men under sentence of death for plundering, one was thus sacrificed every day), the 92nd shot some wild pigs in a wood through which they passed. _Big_ Dugald Campbell, one of their favourite officers, drove his long claymore through the body of a boar which he pursued through the thicket, and claimed from some cazadores. This prize he shared with Cameron and other officers; but the affair drew forth a most severe reprimand from head-quarters, and this was at a time when a _duro_ was given for a handful of oats or nuts, and when some of the officers had no other food for six-and-thirty hours than a few mushrooms or acorns.
Fassifern's regiment formed part of the small force which was left with General Howard to secure Wellington's retreat, by defending the old ruined town of Alba at the passage of the rapid Tormes. There the 50th, 71st, and 92nd made a gallant stand on the 8th of November, 1812. After a long and fatiguing march, and just when about to receive a little ration of dry bread--the first food after three days of starvation--the appearance of the whole pursuing French army under Joseph Bonaparte, summoned the brigade to man the old and shattered walls of Alba--a relic of the Moorish wars--while the sappers undermined the bridge of the Tormes. Two green hills overlooked the town and river. Between these and the wall, within pistol-shot of the 92nd Highlanders, a French staff-officer, mounted on a white charger, had the temerity to ride leisurely reconnoitring, and followed by an orderly on foot. Twenty Highlanders levelled their muskets to shoot this daring fellow, but the chivalric Cameron cried aloud:
"Recover your arms there! I will by no means permit an individual to be fired on!"
This officer who acted so boldly, and thus escaped so narrowly, proved to be no other than _Marshal Soult_, who, in ten minutes after, ordered eighteen pieces of cannon up to the heights, from whence they poured 1300 rounds of shot and shell on the brave brigade of Howard. This was endured until the 13th, by which time Cameron lost forty-two men killed and wounded. At daybreak, on the morning of the 14th, a despatch arrived from Wellington, directing Howard to abandon Alba, as the French cavalry, 3000 strong, had forded the river above the town and turned his flank. A Spanish garrison was left in the old castle of the _Castigador de Flamencos_--the walls were abandoned, and the bridge blown up. Lieutenant John Grant of the 92nd was the last officer who quitted the town, being left to bring off the sentinels, as the French entered, and he was struck by the stones as the mine under the bridge exploded, at the very heels of his party.
