A man must appear somewhat vain, who declares that he has been obliged to reject much useful information, for fear of increasing too much the size of his work: and yet manages to find room for a few pages of his own, by way of Preface: but lest the objects which the compiler of this little work has had in view should be mistaken, he finds it absolutely necessary to say a few words in explanation of them. This small collection of military memorandums was originally intended only for the compiler’s own pocket; to assist him in the execution of his duty: but it occurred to him, that many of his military friends stood in equal need of such an aid, and would willingly give a few shillings for what they would not be at the trouble of collecting. The compiler has seen young men, on their first entry into the regiment of artillery, give a guinea for manuscripts, which contained a very small part of the information offered in this little book. From a persuasion that a very principal part of its merit is derived from its portability, every endeavor has been used to press much into a little compass; and it is hoped, that this power has not been so far exerted, as to make the whole unintelligible: but, it must be understood, that the compiler does not propose to convey instruction to the untaught, but only to make a few memorandums of reference to facts; which those already versed in the military profession are supposed to have the knowledge to apply. The totally ignorant of these matters, he has, therefore, nothing to say to; they must consult more voluminous works. An alphabetical arrangement is merely adopted as the best calculated for this purpose; and as nothing like a military dictionary is intended, all terms are omitted, not within the compiler’s plan. All reference to plates has, likewise been avoided; as they not only very much increase the cost, but the bulk of a book. The principal difficulty which the compiler has had in making this little collection, has been to confine it within the limits of his original plan. The quantity of useful information which has pressed for admittance, has been with reluctance rejected. Such authors only have been quoted, as are generally esteemed the best; and every advantage has been taken of such information, as the compiler has been able to collect from experienced friends; but he has ventured to offer nothing whatever of his own. The French military authors have been principally consulted, on all subjects not immediately confined to our own system; and such notes as are given respecting their ordnance, may be of use in drawing a comparison with our own; and may serve as references to those in the habit of reading their military works. The compiler has not, in any instance, attempted to offer changes which he may have been led to imagine improvements; or to point out what he thinks deserve the title of defects in our own system; but he has given every information according to the present practice in our service. He cannot, however, help expressing a hope, that he will one day see his little book laid by as totally obsolete, and a better built upon a system less complicated, and more applicable to that particular nature of service which this country has in every war the greatest reason to expect.
Our armies will never, it is to be hoped, find a field of battle but on the other side of the water: they must therefore always be subject to the inconveniencies attendant upon the embarkation, and the confusion, too often the companion of a disembarkation of a quantity of ordnance and other military stores upon an enemy’s coast: how peculiarly necessary is it, therefore, that our military system should be the simplest and the best arranged. The French system of artillery was established as far back as the year 1765, and has been rigidly adhered to, through a convulsion in the country, which has overturned every thing else like order; and which even the government itself has not been able to withstand. We should therefore conclude that it has merit, and, though in an enemy, ought to avail ourselves of its advantages. At the formation of their system, they saw the necessity of the most exact correspondence in the most minute particulars; and so rigidly have they adhered to this principle, that though they have several arsenals, where carriages and other military machines are constructed; the different parts of a carriage may be collected from these several arsenals in the opposite extremities of the country, and will as well unite and form a carriage, as if they were all made and fitted in the same workshop. As long as every man who fancies that he has made an improvement is permitted to introduce it into our service, this cannot be the case with us.
Gunpowder has been so much improved of late years, under the direction of Col. Congreve, that the experiments made with the old powder are now of little service: only such tables of ranges with different natures of ordnance have therefore been inserted, as have been ascertained since the improved powder has been in use. As experiments are daily making at Woolwich and elsewhere, a blank leaf may be bound up after each nature of ordnance, in order to insert an abstract of them.
The compiler thinks it necessary to address himself to two classes of persons in particular; perhaps they may comprise the whole of his readers. First, those who think his little book might have been made much more complete. Second, those who think it improper that any information upon such matters should be offered to the public. To the first, he acknowledges the justice of the remark, but has to remind them, of the very great difficulties which they may themselves have experienced, in collecting information at Woolwich. To the second, he has but to remark, that he is well aware of the objections urged against publications which may give information as well to our enemies as our friends; but he does not imagine his little book to contain matter of sufficient consequence to do such mischief: and he is supported in an opinion by the most powerful and best organized military nations in Europe, that such secresy is the surest mark of ignorance.
The first edition being out of print, the compiler has endeavored to improve this, by every correction, and by some of the additions which his friends have been kind enough to suggest to him as necessary: but if he has neglected much of the valuable information offered him, it has not been from an insensibility of its merit, but from its entering more into the detail of matters than his little book would afford room to profit by; for it still professes not to instruct, but only to remind.
The compiler has added to this edition a short alphabetical index to the contents. This may appear to some superfluous, considering the alphabetical arrangement of the subjects: but it has been impossible to avoid a great deal of reference from one part of the work to another: beside, the compiler has observed in several of the copies in the possession of his friends, notes in manuscript, (entered on sheets bound up for the purpose) which are also to be found in the body of the work. This the compiler attributes to a cause which the index may probably remedy, by enabling the reader to know, at one view, the whole contents.
