“COUNTERSIGN, STEADY.--All the grenadiers and light infantry in the garrison, and all the men of the Twelfth and Hardenberg’s regiments, with the officers and non-commissioned officers on duty, to be immediately relieved and join their regiments; to form a detachment, consisting of the Twelfth and Hardenberg’s regiments complete; the grenadiers and light infantry of all the other regiments[17]; one captain, three lieutenants, ten non-commissioned officers, and a hundred artillery; three engineers, seven officers, ten non-commissioned officers, overseers, with a hundred and sixty workmen from the line, and forty workmen from the artificer corps; each man to have thirty-six rounds of ammunition, with a good flint in his piece, and another in his pocket; the whole to be commanded by Brigadier-General Ross, and to assemble on the red sands, at twelve o’clock this night, to make a _sortie_ upon the enemy’s batteries. The THIRTY-NINTH and Fifty-eighth regiments to parade at the same hour, on the Grand Parade, under the command of Brigadier-General Picton, to sustain the _sortie_, if necessary.” At midnight the soldiers assembled for this enterprise; the moon at first shining brightly on the sands, but between two and three o’clock darkness overspread the place, and the troops silently issued from the fortress. They were challenged and fired upon by the enemy’s sentries, but the British soldiers rushed forward, overpowered the Spanish guards, and captured the batteries in gallant style: the defenders of the works fled in dismay, and communicated the panic to the troops in their rear. The wooden batteries were soon prepared for ignition; the flames spread with astonishing rapidity, and a column of fire and smoke arose from the works, illuminating the surrounding objects and casting a lurid glare upon this unparalleled scene, of which words fail to give an adequate description. In an hour the object of the _sortie_ was effected: the Spaniards, being dismayed, did not venture to interrupt the work; trains were laid to the enemy’s magazines, and the soldiers withdrew. As they entered the fortress, tremendous explosions shook the ground, and rising columns of smoke, flame, and burning timber, proclaimed the destruction of the enemy’s immense stores of gunpowder to be completed. General Eliott declared in orders:--“The bearing and conduct of the whole detachment--officers, seamen, and soldiers--on this glorious occasion, surpass my utmost acknowledgments.”
