[267] “A halberd was set up, with a handkerchief fixed to it, and upon this point the chasse-marées boldly stood in for the river. Mr. Bloye, the master’s mate of the Lyra, led the passage. His boat was lost, and the whole of the crew drowned: several others shared the same fate. Captain Elliot, of the Martial, with the surgeon of that vessel and four seamen, and two belonging to the Porcupine, were amongst those who perished. Three transport-boats, with their crews, were also lost. All eyes were turned to witness the vessels plunging through the huge waves that rolled over the bar. A Spanish chasse-marée had nearly struggled through the surf, when an enormous wave was seen gradually nearing the vessel; and, just before it reached it, raising its curling ridge high above the deck, with one fatal sweep bore it down to the bottom. A moment after parts of the shattered vessel rose to the surface, and exhibited the wretched mariners clinging to its fragments: some were drifted till they actually got footing on the shore, and, as it was flood-tide, hopes were entertained of saving them by means of ropes thrown to them; but another tremendous wave rolling majestically on to the beach, in a moment bore them away for ever.”—Batty.
[268] It consisted of six-and-twenty chasse-marées, lashed to each other, and moored by the bow and stem to resist the current that changed at ebb and flow. Heavy guns were occasionally substituted for anchors; and cables were strained by capstans across the centre of the decks, with strong oak planks laid transversely, and sufficiently secured to form a platform, at the same time pliant and substantial—calculated to rise or fall with the tide—and strong enough to support the weight of artillery. Immense stone piers had been erected by the French to contract the channel of the stream, and, by an artificial current, prevent the sand from accumulating on the bar. These, from their breadth, formed an admirable causeway, while they lessened the space of water to be bridged to an extent of two hundred and seventy yards. It was supposed by French engineers impracticable to secure pontoons so as to resist the ocean swells and mountain floods to which the Adour was so constantly exposed; but a fortunate shifting of a sand-bank formed an excellent breakwater; while a boom was laid above the bridge to arrest fire-ships or floating timber, which it might have been expected the enemy would employ for its destruction.
[269] “A few rocket-men were hastily sent across the river, and posted on the sandhills to aid in repelling the enemy; and two guns of the troops of horse-artillery were so placed on the left bank of the river, as to be able to flank by their fire the troops coming on to attack the front of the guards.
“The enemy came on a little before dusk of evening with drums beating the pas-de-charge, and driving before him the pickets sent out by General Stopford to reconnoitre. The guards awaited the approach of the French columns till within a short distance of their front, and then commenced a well-directed fire; the guns on the left bank began to cannonade them, and the rockets on the sandhills were discharged with terrific effect, piercing the enemy’s column, killing several men, and blazing through it with the greatest violence. The result was the almost immediate rout of the French, who, terror-struck at the unusual appearance, and at the effect of the rockets, and the immovable firmness of the little corps, made the best of their retreat back towards the citadel, leaving a number of killed and wounded on the ground. This gallant little combat closed the events of the day.”—Batty.
[270] “There was a prejudice in the army against this weapon, which had hitherto not been used in the field; the opinion seems to have been, that if it had been an efficient means of destruction, it would sooner have been borrowed from the East Indian nations. Lord Wellington, however, was willing that they should be tried; and some experiments which were made at Fontarabia gave reason for supposing that they might be found useful on the Adour. The direction of this new arm was assigned to Sir Augustus Fraser, but the trial was to be made under all the disadvantages of inexperience; for the corps was composed of men hastily brought together, and entirely ignorant of the arm they were to use; and the rockets themselves were equipped in five different ways, and consequently liable to as many failures.”—Southey.
A twelve-pounder rocket laid on the ground, and discharged without a tube, by simply applying a match to the vent, will run along the ground four or five hundred yards, seldom rising higher than a man’s head; and then, alternately rising and falling, will continue its course with such effect, as, after ranging 1200 yards, to pierce through twenty feet of turf, and explode on the other side, scattering the seventy-two carbine balls, with which it was loaded, in all directions. No barricade could for an instant retard its force; and should it by any accident strike against a stone, or any obstacle which it cannot pierce or overturn, it will bound off, and continue its terrible course.
They are of various dimensions, as well in length as in calibre, and are differently armed, according as they are intended for the field or for bombardment,—carrying, in the first instance, either shells or case-shot, which may be exploded at any part of their flight, spreading death and destruction among the columns of the enemy; and in the second, where they are intended for the destruction of buildings, shipping, stores, &c. they are armed with a peculiar species of composition which never fails of destroying every combustible material with which it comes in contact: the latter are called carcass-rockets.
The powers of this weapon are now established upon the best of all testimonies—that of the enemy; a striking instance of which occurred at the siege of Flushing, where General Monnet, the French commandant, made a formal remonstrance to Lord Chatham respecting the use of them in that bombardment.
The form of all the different kinds of these rockets is cylindrical, and they are composed of strong metallic cases, armed, as before stated, either with carcass composition for bombardment and conflagration, or with shells and case-shot for field-service. They are, however, of various weights and dimensions, from the eight-inch carcass, or explosion-rocket, weighing nearly three hundredweight, to the six-pound shell-rocket, which is the smallest size used in the field. The sticks which are employed for regulating their flight are also of different lengths, according to the size and service of the rocket, and which, for the convenience of carriage, are stowed apart from the rocket, and so contrived as to consist of two or more parts, which are connected to it, and to each other when requisite, with the utmost expedition.
They are divided into three classes, heavy, medium, and light,—the former including all those of above forty-two pounds, which are denominated according to their calibre, as eight-inch, seven-inch, six-inch, &c. rockets; the medium include all those from the forty-two pound to the twenty-four pound rocket; and the light, from the eighteen-pounder to the six-pounder, inclusive. The carcass-rockets are armed with strong iron conical heads, containing a composition as hard and solid as iron itself, and which, when once inflamed, bids defiance to any human effort to extinguish it, and, consequently, involves in an inextinguishable flame every combustible material with which it comes in contact. The forty-two pounder and thirty-two pounder carcass-rockets are those which have hitherto been chiefly employed in bombardments. The penetration of the thirty-two pound carcass-rocket, in common ground, is nine feet,—and in some instances where they have been employed, have been known to pierce through several floors, and through the sides of houses: this is the smallest rocket used in bombardment, and the largest employed in the field,—the more usual size for the latter service being the twenty-four, eighteen, twelve, and six-pounders. The ranges of the eight-inch, seven-inch, and six-inch rockets, are from 2,000 to 2,500 yards; and the quantity of combustible matter, or bursting powder, from twenty-five to fifty pounds; and from their weight, combined with less diameter, they possess a greater power of penetration than the heaviest shells, and are therefore equally efficient for the destruction of bomb-proofs, or the demolition of strong buildings.
