To make his regiment as efficient as possible, he ordered that no officer who had been less than ten years in the service should ride on the march; this diminished the number of useless horses which every regiment then possessed; while to increase the number of bayonets, he turned the whole of the band into the ranks; thus, throughout the whole Peninsular War, he retained only the bagpipes, drums, and fifes. His regiment belonged to the 1st Brigade, or General Howard's, in the 2nd Division of Infantry, or Lord Hill's, with the 50th, under Colonel Stuart, and the 71st Highlanders, under Colonel Cadogan, with both of whom his fiery temper and jealousy on points of etiquette soon involved him in a coolness that lasted till they were both removed by death. The Highlanders entered Spain by the way of Albergaria, and their peculiar garb soon changed the constant cry of "_Live the English_," to "_Viva los Escotos! Viva Don Juan Cameron, y sus valiante Escotos! Viva!_" This was when following up the retreating Massena. Notwithstanding all efforts of that general to restore the barbarities of ancient warfare, much good feeling prevailed between the French and British when out of the field. Of this, one anecdote will suffice. A French picket in front of Cameron's regiment, were about to slay a bullock for their dinner, when the animal broke loose, and dashed across the neutral ground, where a Highlander killed it by a single ball, and his comrades proceeded immediately to cut up their prize in view of the hungry and disappointed foe, who sent over two soldiers, waving white handkerchiefs. Under these extempore flags of truce, they brought a message from their officer, saying that he was "sure Scottish soldiers were too generous to deprive his men of the only provisions they had seen for some days." The Highlanders sent them back with half the beef, several loaves of bread, and a bottle of rum. After this, they became so familiar that some of our pickets went over and drank with those of the enemy, until Wellington's order forbade it as unsafe and improper. Cameron distinguished himself by his activity, at the head of his gallant Highlanders, in all the arduous operations of that sanguinary war. He led his regiment at Fuentes d'Onor, where it was on the right, covering a brigade of nine pounders, when it endured a severe cannonade, and had thirty-seven officers and men killed and wounded. Major Peter Grant had his arm torn off by a cannon-shot, but he survived to die lately, at a good old age, amongst his kindred in Strathspey.
