But such reasoners also calculate upon what would happen in an engagement between two fleets, in which steam-ships of a large class would be more numerous on one side than the other; for they could at once act together, regardless of wind or weather, and thus concentrating their force, they could cut off or destroy a certain part of their opponent's fleet, before sailing vessels could possibly come to their assistance. They also calculate upon this manœuvre being repeated upon the remainder of the enemy's ships, which cannot escape from these powerful steamers.
These are points, however, for seamen to decide; yet suppose a steamer, calculated to carry only a few traversing guns of the longest range for shot or shells, with what are usually termed percussion locks, to insure good practice even when the vessel is in motion, to be well managed or manœuvred by a skilful naval officer; and should he occasionally use shot heated in the furnaces for the boilers, what a formidable opponent she must prove, especially in a calm, or even in a storm, to any sailing vessel. Many officers may remember what treatment our ships of war frequently met with in parts of the Mediterranean, from even a single Spanish gun-boat, carrying perhaps but one long gun; and when the facility and rapidity of movement of a steamer are considered, there can be no comparison whatever drawn between her and a common gun-boat, even when propelled by sweeps or oars, but which become useless in a rough sea. Such matters as these can, however, be brought by calculation to something very near to certainty as to results.
I am aware that the great difficulty which presents itself at present is how to protect from shot the chimneys, paddles, and machinery of war-steamers; but if, in these times, when science is daily performing such wonders amongst us, sufficient rewards were offered for the best plans for this purpose, I have no doubt but we should soon see much accomplished; but even until this may be effected, the position which can be taken up by the steamer will, it is thought, insure her being no great sufferer from the shot fired from a sailing vessel. But these, and many other points connected with steam, will be fully elucidated the very first war in which we may be seriously engaged; but in the mean time much can be immediately done, by merely making some useful experiments, whereby we may, to a considerable extent, be taught whether it be advisable or not for us to continue, at a great expense, building and equipping, at all events for what may be termed home service, the present description of sailing vessels, or whether it would not be prudent to direct more attention to war steamers, or to those ships which are propelled by both sails and steam; though I should fear that this combination of the two propelling powers must be found objectionable, as both would most likely be imperfect.
For foreign service, or for those parts of the world where the necessary supplies of fuel for steamers cannot easily be procured, the combining the two principles in a ship may be useful; but wherever perfect steamers can be available, they should decidedly have the preference. But for some time to come, causing both steamers and sailing vessels to act together for mutual assistance and support in action, especially in distant parts of the world, must obviously be desirable.
It appears to be demonstrated that a steamer, from fifteen hundred to two thousand tons burden, and upwards, possesses great proportional advantages over one of only four or five hundred, in carrying troops, cargo, or fuel; and her increased power of steam, gives her also proportional superiority in forcing her way through the water, and storms or heavy seas have much less effect upon her than upon smaller vessels. A steamship of war of two thousand tons burden, well manned and armed—and she need not carry many, but they ought to be guns of long range—must possess such powers of movement, and of destruction, as cannot be easily calculated or understood; and conceive that ship to carry, independent of her crew, (which need not be anything like so numerous as that of even a large frigate,) a regiment of cavalry, or two of infantry; then suppose thirty such steam ships conveying an army of perhaps 30,000 men, cavalry, infantry, and artillery, such as I am so anxious to have called out in the manner I have proposed, and which could be carried by these irresistible steamers into almost any port having sufficient depth of water, or to any selected point, and there landed, ready to act against an unprepared, or perhaps distracted people; and how easy it would be with such ships to supply an army afterwards with every requisite; and the object in view being accomplished, or even if frustrated, with what little difficulty could the troops, and their materiel, be again received on board, and conveyed to any other point of attack, or back to our own shores.
I had written the above observations, when I saw, by accident, the following description of the Cyclops steam frigate, and from what is said of her, it may be seen what I had in view. A few of the 96-pounders will soon decide the fate of a battle.
"The Cyclops, Steam Frigate.—This magnificent vessel, the largest steam man-of-war in the world, was launched from Pembroke Dock-yard a few days ago. Her dimensions are as follow:—Length 225 feet, beam between paddles 38 feet, depth of hold 21 feet. Her tonnage is about 1,300, being 200 tons larger than the Gorgon, launched from the same slip about eighteen months since. Her equipment, as a man-of-war, will be the same in all respects as a frigate, having a complete gun, or main-deck, as well as an upper or quarter-deck. On the main-deck she will carry eighteen long 36-pounders, and on the upper deck four 48-pounders, and two 96-pounders on swivels, carrying a ball of ten inches diameter, and sweeping round the horizon 240 degrees. The Cyclops, like the vessel already referred to, will be commanded by a post-captain, these two being the only steamers taking frigate's rank. Her crew will consist of 210 men, 20 engineers and stokers, and a lieutenant's party of marines, who will have charge of the guns, all of which move upon slides and fixed pivots, thereby taking a much wider range than the ordinary carriages can give. She will be schooner-rigged, but her foremast will be of the same scantling and height as that of a 36-gun frigate. Her draught of water, with all on board, including six months' provisions, completely armed, and with twenty days' fuel, will be fifteen feet. This quantity of fuel (400 tons) will be carried in the engine-room, but there is a space in the fore and after holds for ten days more coal, making, in all, sufficient fuel for a thirty days' run. She has an orlop deck below the gun-deck, of dimensions so magnificent that there is room to stow with comfort eight hundred troops and their officers; so that, taking her all in all, the Cyclops may be considered the most powerful vessel in her Majesty's service. The Cyclops has been built in six months, under the immediate inspection of Mr. W. Eyde, master-builder, of Pembroke-yard, from drawings and plans prepared by his brother, Mr. John Eyde, the able assistant of Sir W. Symonds, the inspector of the navy, upon whose principle—namely, the combining of the sailing and steaming properties—this vessel has been constructed. The Cyclops will be docked in Sheerness Dock-yard on the 30th instant, and, after remaining there for a few days, will proceed to the manufactory of Messrs. Seaward, at Millwall, Poplar, to receive her engines, which will be of 320 horsepower, on the principle which, in the case of the Gorgon, has proved so successful that the Lords of the Admiralty have given orders for five more pairs of engines upon the same plan, for as many frigates. Half-a-dozen such steamers would do three times as much work as the same number of line-of-battle ships. Twelve years ago Lord Cochrane maintained, that a few well-appointed steamers would suffice to keep in check opposing fleets in the Mediterranean; and if we may judge from appearances, a short time only will elapse before the experiment is tried."
Suppose also that each of these powerful steamers had assigned to her to take in tow, when necessary, a sailing vessel, conveying either additional troops, horses, coals, provisions, forage, &c. &c., how much more formidable such an armament would become.
In combined naval and military operations, I should conclude that the usual mode of proceeding would be to secure the point of debarkation, or any other considered more suitable, so as to admit of the army being again received on board the ships with as little difficulty and loss as possible; for we may well suppose that the exasperated and suffering inhabitants would do every thing in their power to destroy and annoy the invaders. Field entrenchments, but on as confined a scale as possible, must be thrown up with skill and rapidity, in situations to favour the re-embarking of the army, with all that belongs to it; and how essential it must then be, that soldiers should be as much accustomed to the use of the pickaxe and shovel as to their arms; in short, it will become indispensable that they should have habits of working, like the Roman soldiers of old.
Let us consider the consequences of such a descent. The country to a considerable extent must be instantly over-run by an army perfect in all respects, and amply supplied independent of the invaded country. Should the destruction of the power of an adversary in steam be alone the object, gunpowder and other means we can readily command, would speedily accomplish this. Dock-yards, building-yards, coal pits, mines, machinery, railways, constructed at enormous expense, and all public and private works of vast value—in a few days, and before any force sufficient for their protection could be assembled, might be laid in ruins, or so destroyed, as to render the amount of mischief done incalculable. But these are matters which demand instant and due consideration; and the country should be prepared to meet the expense which must be incurred, if it is only to ensure our exemption from such mortifications and misfortunes. Fortifications can afford a country but little protection against such calamities; for to a superiority in steam ships we can alone look for this, and to that Omnipotent Being who can influence the judgments and views of those who, by Him, are permitted to direct the affairs of this mighty empire.
