After incessant skirmishes and daily marches along the banks of the Tagus, and after a desperate affair of outposts at La Nava, on the 18th May, 1812, Hill marched to destroy the forts erected by the French at the bridge of Almarez. The 50th, and a wing of the 71st Highlanders, formed one column, which was destined to attack Fort Napoleon; Cameron with his regiment, and the remainder of the 71st, had orders to support the attack, and storm the _tete-du-pont_. Both columns were amply provided with scaling-ladders. As the troops descended a _rut_ of the sierra, in Indian file, about midnight, Mr. Irvine, a gentleman volunteer, left his ranks to obtain a draught of water. This was contrary to express orders; and such was Cameron's strictness, that he dismissed him from the regiment on the instant, and the poor fellow was left alone among the mountains of Romangordo. Being proud of his own regiment, Cameron had a great jealousy of the 71st Highlanders; and when the attack commenced, on some of their bullets, in the twilight and confusion, whistling over his own ranks, he called aloud-- "Seventy-first! what the devil are you about? Do you wish the ninety-second to return your fire?" Fort Napoleon was stormed in gallant style. Captain Candler, of the 50th, was shot through the head; but the French were driven towards the _tete-du-pont_. Then Cameron entered it with them pell-mell, with bayonets charged, muskets clubbed, swords and sledge-hammers. But the commandant of Fort Ragusa, on the opposite side, cut the pontoon bridge, and thus the whole garrison of Fort Napoleon found the deep Tagus before them, and the foe behind. Eager to capture Ragusa, many of Cameron's men flung themselves into the river, and daringly swam across. Privates Gall and Somerville were the first men who brought over the pontoon bridge. On gaining possession of the platforms, which were literally ankle-deep in brains and blood, the 1st brigade slued round the cannon upon the French, and blew their heads off in scores, as they crowded into the square of the little fortress, where the 71st Highlanders captured a standard of the _Corps Etranger_.
