did. The large ball, in combination with the restricted windage and

the small charge of powder, gave the Smasher ballistic results far superior, relatively, to those obtained with the long gun. Its lack of ranging power was admitted. But for close action it was claimed that it would prove an invaluable weapon, especially in the defence of merchant ships.[86] Not only would its large ball make such holes in the light hull of an enemy privateer as would break through his beams and frames and perhaps send all hands to the pumps; but, projected with just sufficient velocity to carry it through an opponent’s timbers, it would thereby produce a maximum of splintering effect and put out of action guns, their crews, and perhaps the vessel itself.

§

On the lines of the Smasher the “lesser carronades,” more convenient in size and more easily worked, were cast, and quickly made a reputation in merchant shipping. The Smasher itself was offered to the admiralty, but was never fitted in a royal ship; though trials were carried out with it later with hollow or cored shot, to ascertain how these lighter balls compared in action with the solid 68-pounders. Meanwhile the Carron Company found a large market for the lighter patterns of carronade; the 24, 18, and 12-pounders were sold in large numbers to private ships and letters-of-marque, and to some of the frigates and smaller ships of the royal navy. The progress of the new ordnance was watched with interest by the board of admiralty. In 1779 we have Sir Charles Douglas writing to Sir Charles Middleton in full accord with his views on the desirability of mounting Carron 12-pounders on the poop of the _Duke_, and suggesting 24-pounders, three a side, upon her quarter-deck. To the same distinguished correspondent Captain Kempenfelt writes, deploring that no trials have yet been made with carronades. Shortly afterwards the navy board discusses the 68-pound Smasher and desires the master-general of ordnance to make experiment with it. A scale is drawn up by the navy board, moreover, and sanctioned by the admiralty, for arming different rates with 18-and 12-pounder carronades. The larger classes of ships, the first, second, and third rates, have their quarter-decks already filled with guns; but accommodation is found for a couple of carronades on the forecastles, and for half a dozen on the poop, which for nearly a century past has served chiefly as a roof for the captain’s cabin. This is now timbered up and given three pairs of ports, making a total of eight ports for the reception of carronades. In the case of smaller ships less difficulty is experienced. Ports are readily cut in their forecastles and quarter-decks, and in some cases their poops are barricaded, to give accommodation for from four to a dozen carronades.[87]

The new weapon found its way into most of our smaller ships, not always and solely as an addition to the existing long-gun armament, for use in special circumstances, but in many cases in lieu of the long guns of the establishment. The saving in weight and space gained by this substitution made the carronade especially popular in the smaller classes of frigate, the sloops, and brigs; many of which became almost entirely armed with the type. The weak feature of the carronade, which in the end was to prove fatal to it--its feeble range and penetrating power--was generally overlooked, or accepted as being more than compensated for by its many obvious advantages. The carronade, it was said by many, was the weapon specially suited to the favourite tactics of the British navy--a yard-arm action.

There were others, however, who were inclined to emphasize the disability under which the carronade would lie if the enemy could contrive to avoid closing and keep just out of range. And on this topic, the relative merits of long gun and carronade as armament for the smaller ships, discussion among naval men was frequent and emphatic. The king’s service was divided into two schools. The advocates of long guns could quote many a case where, especially in chase, the superior range of the long gun had helped to win the day. The advocates of the carronade replied with recent and conclusive examples of victories won by short-gun ships which had been able to get to grips and quickly neutralize the advantages of a superior enemy armed with long guns. When challenged with the argument that, since the advantages of the carronade entirely disappear at long ranges it is essential that ships armed with them should be exceptionally fast sailers, they replied, that the very lightness of a carronade armament would, other things being equal, give ships so armed the property required. As for out-ranging, they were even ready to back their carronades in that respect, if only they were well charged with powder. It was a matter of faith with many that, in spite of Dr. Hutton’s published proof to the contrary, a considerable increase of range could be obtained by the expedient of shortening the gun’s recoil; so that in chase it was a common procedure to lash the breechings of carronades to the ship’s timbers, to prevent recoil and to help the shot upon its way.

At first mechanical difficulties occurred in the fitting of the new carronade mountings which, though not due to any defect inherent in the equipments, nevertheless placed them under suspicion in certain quarters. Though the prototype had trunnions like a gun, the carronades afterwards cast were attached by lugs to wooden slides which recoiled on slotted carriages pivoted to the ship’s side timbers, the slide being secured to the carriage by a vertical bolt which passed down through the slot. The recoil was limited by breechings; but as these stretched continuously the bolt eventually brought up with a blow against the end of the slot in the carriage: the bolt broke, and the carronade was disabled. This happened at Praya Bay, where the carronades broke their beds, owing to slack breechings, after a few rounds. Captains complained, too, that the fire of the carronades was a danger to the shrouds and rigging.

In spite of these views the popularity of the new ordnance increased so rapidly that in January, 1781, there were, according to the historian James, 429 ships in the royal navy which mounted carronades. On the merits of these weapons opinion was still very much divided. The board of ordnance was against their adoption; the navy board gave them a mild approval. In practice considerable discretion appears to have been granted to the commanders of ships in deciding what armament they should actually carry.[88] But the uncertainty of official opinion gave rise to a surprising anomaly: _the carronade, although officially countenanced, was not recognized as part of the orthodox armament of a ship_. What was the cause of this is not now clear. It has been said in explanation, that the carronade formed too fluctuating a basis on which to rate a ship’s force; that a long-gun basis afforded a key to the stores and complement of a ship, whereas carronades had little effect on either complement or stores; or that it may have been merely inertia on the part of the navy board. Whatever the cause, the ignoring of the carronade, in all official quotations of ships’ armaments, led to great uncertainty and confusion in estimating the relative force of our own and other navies, to suggestions of deception on the part of antagonists, to the bickering of historians and the bewilderment of the respective peoples. This extraordinary circumstance, that carronades with all their alleged advantages were not thought worthy to be ranked among the long guns of a ship, is commented on at length by James. “Whether,” he says, “they equalled in calibre the heaviest of these guns, added to their number a full third, or to their power a full half, still they remained as mere a blank in the ship’s nominal, or rated force, as the muskets in the arm-chest. On the other hand, the addition of a single pair of guns of the old construction, to a ship’s armament, removed her at once to a higher class and gave her, how novel or inconvenient soever, a new denomination.”

While the products of the Carron firm were gaining unexpected success in the defence of merchant shipping, their value in ships of the line was not to remain long in doubt. Some of the heavier carronades had been mounted in the _Formidable_, _Duke_, and other ships, and their presence had a material effect in Admiral Rodney’s action of April, 1782. As had been generally recognized, the carronade was especially suited to the British aims and methods of attack--the destruction of the enemy by a yard-arm action. To the French, whose strategy and methods were fundamentally different, its value was less apparent. So that for long this country reaped alone the benefit of its invention; until in somewhat half-hearted way France gradually adopted it, and then mostly in the smaller sizes, and more apparently with a view to defence than for offensive purposes. In the action with de Grasse the carronades of the British fleet operated, in the opening stages, as an additional incentive to the enemy to avoid close quarters. And later, at the in-fighting, their weight of metal contributed in no small degree to the superiority of fire which finally forced him to surrender.

It was later in this same year that the carronade won its most dramatic victory as armament of a small ship. In order to give a thorough trial to the system the navy board had ordered the _Rainbow_, an old 44, to be experimentally armed with large carronades, some of which were of as large a calibre as the original Smasher; by which her broadside weight of metal was almost quadrupled. Thus armed she put to sea and one day fell in with the French frigate _Hébé_, armed with 18-pounder long guns. Luring her enemy to a close-quarter combat, the _Rainbow_ suddenly poured into the Frenchman the whole weight of her broadside. The resistance was short, the _Hébé_ surrendered, and proved to be a prize of exceptional value as a model for frigate design. The capture was quoted as convincing proof of the value of a carronade armament, and the type continued from this time to grow in popularity, until the termination of the war in 1783 put a stop to further experiments with it.

§

Throughout the long war which broke out ten years later the carronade played a considerable part in the succession of duels and actions which had their climax off Trafalgar. It was now generally adopted as a secondary form of armament, captains being permitted, upon application, to vary at discretion the proportion of long-gun to carronade armament which they wished to carry. In the smaller classes especially, a preponderance of carronades was frequently accepted; the accession of force caused by the substitution of small carronades for 6-and 9-pounder long guns in brigs and sloops could hardly be disputed. In ships-of-the-line the larger sizes continued in favour. The French now benefited, too, by their adoption; on more than one occasion their poop and forecastle carronades, loaded with langrage, played havoc with our personnel. Spaniards and Dutchmen did not carry them. How far their absence contributed to their defeats it is not now to inquire; but how the tide of battle would have been affected by them--if the Dutch fleet, for instance, had carried them at Camperdown--may be a not unprofitable speculation.

Early in the war the carronade system was to score its greatest defensive triumph, and this, by a happy coincidence, in the hands of the old _Rainbow’s_ commander.

The _Glatton_, one of a few East Indiamen which had been bought by the admiralty, was fitted out in 1795 as a ship of war, and left Sheerness in the summer of the following year under the command of Captain Henry Trollope to join a squadron in the North Sea. At her commander’s request she was armed with carronades exclusively. She was without ahead or astern fire, without a single long bow or stern chaser; she carried 68-pounder carronades along her sides, whose muzzles were so large that they almost filled the small port-holes of the converted Indiaman and prevented more than a small traverse. Off the Flanders coast she fell in one night with six French frigates, a brig-corvette, and a cutter; and at ten o’clock a close action began. The _Glatton_ was engaged by her antagonists on both sides, her yard-arms almost touching those of the enemy. She proved to be a very dangerous foe. Her carronades, skilfully pointed and served by supply parties who worked port and starboard pieces alternately, poured out their heavy missiles at point-blank range. So heavy was her fire that one by one the frigates had to haul off, severely damaged, and the _Glatton_ was left at last to spend the night repairing her rigging unmolested, but in the expectation that the French commodore would renew the attack in the morning. To her surprise no action was offered. The blows of the 68-pounders had done their work. Followed by the _Glatton_ with a “brag countenance,” the enemy retired with his squadron in the direction of Flushing.

The action had more than one lesson to teach, however, and no more ships, except small craft, were armed after this upon the model of the _Glatton_.

We must at this point mention an experiment made in the year 1796, at the instance of Sir Samuel Bentham, in the mounting of carronades on a non-recoil system. Sir Samuel, who in the service of Russia had armed long-boats and other craft with ordnance thus mounted, produced arguments before the navy board for attaching carronades rigidly to ships’ timbers; so as to allow of no other recoil than that resulting from the elasticity of the carriage and the materials connecting it to the ship. The ordnance board reported against the new idea. Sir Samuel pointed out that the idea was not new. Both the largest and the smallest pieces used on board ship (viz. the mortar and the swivel) had always been mounted on the principle of non-recoil. He showed how bad was the principle of first allowing a gun and its slide or carriage to generate momentum in recoil and then of attempting to absorb that momentum in the small stretch of a breeching-rope. He argued that a rifle held at the shoulder is not allowed to recoil: if it is, the rifleman smarts for it. He instanced the lashing of guns fast to the ship, especially in chase, for the purpose of making them carry farther. No; the novelty consisted in preparing suitable and appropriate fastenings for intermediate sizes of guns between the mortar and the swivel. The adoption of his proposal, he contended, would result in smaller guns’ crews, quicker loading, and greater safety.

As a result of these arguments certain sloops designed by him were armed on this principle; and in other cases, notably in the case of the boats used at the siege of Acre, the carronades and smaller types of long gun were successfully mounted and worked without recoil by attaching their carriages to vertical fir posts, built into the hull structures to serve as front pivots. But, generally, the system was found to be impracticable. The pivots successfully withstood the stresses of carronades fired with normal charges of powder; no permanent injury resulted to the elastic hull structures over which the blows were spread. But the factor of safety allowed by this arrangement was insufficient to cover the wild use of ordnance in emergencies. The regulation of charges and the prevention of double-shotting was difficult in action, and pieces were liable to be over-charged in the excitement of battle in a way which Sir Samuel Bentham had failed to realize. Pivots were broken, ships’ structures strained, and the whole system found ill-adapted for warship requirements.

It was not till the war of 1812 that the fatal weakness of the carronade, as primary armament, was fully revealed. The Americans had not developed the carronade policy to the same extent as ourselves, for transatlantic opinion was never at this period enamoured of the short-range gun. Their well-built merchant ships, unhampered by tonnage rules or by the convoy system which had taken so much of the stamina from British shipping, were accustomed to trust to their speed and good seamanship to keep an enemy at a distance. Their frigates, built under less pedantic restrictions as to size and weight, were generally swifter, stouter and more heavily armed than ours. And, though they included carronades among their armament, these were not generally in so large a proportion as in our ships, and in part were represented by a superior type--the colombiad, a hybrid weapon of proportions intermediate between the carronade and the long gun. Our ships often depended heavily upon the carronade element of their armament. Experience was soon to confirm what foresight might, surely, have deduced: namely, that when pitted against an enemy who could choose his range and shoot with tolerable accuracy the carronade would find itself in certain circumstances reduced to absolute impotence.

This was to be the fate and predicament of our ships on Lakes Erie and Ontario, in face of the Americans. “I found it impossible to bring them to close action,” the English commodore reported. “We remained in this mortifying situation five hours, having only six guns in all the squadron that would reach the enemy, not a carronade being fired.” The same lesson was to be enforced shortly afterwards on the Americans. One of their frigates, the _Essex_, armed almost exclusively with carronades, was fought by an English ship, the _Phœbe_, armed with long guns. The _Essex_, it should be noted, possessed the quality essential for a carronade armament, namely, superior speed. But the _Phœbe_ fell in with her in circumstances when, owing to damage, her superior speed could not be utilized. The captain of the _Phœbe_ was able to choose the range at which the action should be fought. He kept at a “respectful distance”: within range of his own long guns and out of range of his opponent’s carronades. Both sides fought well, but the result was a foregone conclusion. The _Essex_, disabled and on fire, had to surrender. From that time the carronade was discredited. For some years after the peace it found a place in the armament of all classes of British ships, but it was a fallen favourite. The French commission which visited this country in 1835 reported that, although still accounted part of the regular armament of older ships, the carronade was being replaced to a great extent by light long guns in newer construction. Opinion certainly hardened more and more against the type, and, gradually falling into disuse, it was at last altogether abandoned.

There was a feature of the carronade, however, which if it had been exploited might have made the story of the carronade much longer: might, in fact, have made the carronade the starting-point of the great evolution which ordnance was to undergo in the second quarter of the nineteenth century. We refer to the large area of its bore, as rendering it specially suitable for the projection of hollow spheres charged with powder or combustibles: in short, for shells. Although, as shown by the inscription on the model presented to him, General Melville’s invention covered the use of shell and carcass shot, yet there was no general appreciation in this country, at the time of its invention, of the possibilities which the new weapon presented for throwing charges of explosive or combustible matter against the hulls of ships. Empty hollow shot were tried in the original Smasher for comparison against solid shot, in case the latter might prove too heavy;--and these, as was pointed out by an eminent writer on artillery,[89] possessed in an accentuated degree all the disadvantages of the carronade system, their adoption being tantamount to a reversion to the long-exploded granite shot of the medieval ordnance--but the use of _filled_ shell in connection with carronades does not appear to have been seriously considered. The disadvantages of filled shell as compared with solid shot were fairly obvious; their inferiority in range, in penetrative power, in accuracy of flight, their inability to stand double-shotting or battering charges--all these were capable of proof or demonstration. Their destructive effect, both explosive and incendiary, as compared with that of uncharged shot, was surprisingly under-estimated. Had it been otherwise, the carronade principle would have led naturally to the introduction of the shell gun. “The redeeming trait in the project of General Melville,” wrote Dahlgren, “the redeeming trait which, if properly appreciated and developed, might have anticipated the Paixhans system by half a century, was hardly thought of. The use of shells was, at best, little more than a vague conception; its formidable powers unrealized, unnoticed, were doomed to lie dormant for nearly half a century after the carronade was invented, despite the evidence of actual trial and service.”

In other respects the carronade did good service in the development of naval gunnery. Its introduction raised (as we have seen) the whole question of windage and its effects, and was productive of general improvement in the reduction and regulation of the windage in all types of gun. By it the advantages of quick firing were clearly demonstrated. And by its adoption in the ship-of-the-line it contributed largely to bring about that approach to uniformity of calibre which was so marked a feature of the armament schemes of the first half of the nineteenth century.
