Marine. A soldier serving on ship-board; a sea-soldier; one of a body of troops trained to do duty on vessels of war.
Marine Fortification. This kind of fortification differs from land fortification in that the approaches of the enemy which are to be resisted take place on the level of the sea, so that he can come near without having to overcome the dangerous slope of the glacis. The combat is simply one between two powerful batteries, and the question to be decided is, whether the ship or the fort will first be placed [hors de combat]; the ship having ordinarily the largest number of guns, while the fort has more solid battlements, and its fewer guns of great caliber can be fired with a steadiness unattainable on so shifting a base as the ocean. Under these circumstances, the less relief a sea-fortress has the better, the less likely is it to be hit from shipping. Its walls are usually built perpendicular, or nearly so. The magazines and quarters for the men are bomb-proof, as also are the casemates, from which the guns are usually fired, although sometimes, as in the martello tower, the gun is worked on top of the structure. Sea fortifications may be of various importance, the simplest being the battery consisting of a mere parapet formed in a cliff or on a hill, and mounted with guns to command the sea; these are generally built in such concealed situations, that it is hoped the hostile ship will not perceive them until they actually open fire. These are numerous all around the British coast. Next greater in importance is the [martello tower] (which see). More powerful still are the breach-forts, such as those which on either shore defend the entrance to Portsmouth harbor, England. These are constructed of the most solid masonry, and armed with guns of the heaviest caliber, sweeping the very surface of the sea so as to strike an approaching ship between wind and water. The guns are usually in bomb-proof casemates, and the fort is often defended on the land side, if the coast be level; if, however, higher ground be behind, this would be useless, and then the sea-front alone is defensible. Most terrible of all sea-forts, however, are the completely isolated forts with perpendicular faces and two and three tiers of heavy guns. Such are the tremendous batteries which render Cronstadt almost unapproachable, and by which Spithead and Plymouth Sound, England, are now being fortified. These forts are generally large, with all the requisites for a garrison to maintain itself; against them wooden ships stand no chance, and in the American civil war, Fort Sumter, at Charleston, has shown itself no mean antagonist for ironsides. In the new forts, as Spithead, etc., iron is to be employed as the facing, in plates of such vast thickness and weight that it is supposed no ship can ever possess any comparable power; and as they are to be armed with guns the smallest of which will probably be 300-pounders, it is expected that they will be able to destroy any fleet that could be sent against them. At the present day, the value of sea fortifications is disputed, as iron-plated vessels may pass them with impunity, unless the artillery in the fort be so heavy as to destroy the armor of the ships. In the long run, however, it is apparent that the fort can command the greater power; for its armor may be of any thickness, while that of the ship must be limited by her floating powers, and on the other hand, the limit to the size of artillery must be sooner reached in a ship than in a solid and stationary fortress.
Marines, Corps of. In the U. S. service is a body of troops who serve at the different naval stations, and on board ships of war. The men are drilled in all respects as infantry, and therefore, when on shore, are ordinary land forces. On board ship, their ordinary functions are as sharpshooters in time of action, and at other times to furnish sentries for guarding the stores, gangways, etc.; and they are useful as exercising a good control over the less rigidly disciplined sailors. They are also instructed as guns’ crews, and when not on guard, are subject to the orders of the naval officers in the same manner as the seamen. The corps was first established in the United States in 1775, and was permanently organized by act of Congress in 1798. By this act, marines were made liable to do duty at the call of the President in any of the forts or posts of the United States, and were placed on the footing of infantry soldiers, as far as regards pay and allowances. When detached for duty with the army, marines are subject to the Articles of War; at all other times they are subject to the laws and regulations for the government of the navy. The corps numbers about 2000 men commanded by a colonel. The corps has undergone many changes in respect of numbers, equipment, drill, and methods of recruiting since its organization, and was never in a better state of discipline and efficiency than now. No man is enlisted who is unable to read and write, under 5 feet 6 inches high, or over thirty-five years of age. It is organized into battalions for duty on shore, and into “guards,” or companies, for service afloat, each having its proper complement of officers, non-commissioned officers, musicians, and privates, and is considered an indispensable auxiliary to the navy. Civilians between twenty and twenty-five years of age are eligible at present to appointment as lieutenants in line of promotion, and are stationed at the head-quarters of the corps in Washington for their preliminary instruction. In the British service, besides the infantry, there is a division of marine artillery. In rank, marine officers correspond with army officers of the same grade, according to seniority; they are usually appointed from civil life.
Maritime. Bordering on, or situated near, the ocean; connected with the sea by site, interest, or power.
Mark. That toward which a missile is directed; a thing aimed at; what one seeks to hit or reach.
Mark, St., Knights of. An order of knighthood which formerly existed in the republic of Venice, under the protection of St. Mark the Evangelist.
Mark Time. To mark time is to move each leg alternately in quick or ordinary time, without gaining ground. This is frequently practiced when a front file or column has opened too much, in order to afford the rear an opportunity of getting up; and sometimes to let the head of a column disengage itself, or a body of troops file by, etc.
Marker. The soldier who forms the pivot of a wheeling column, or marks the direction of an alignment. Also, the one who records the number of hits and misses made by soldiers at target practice.
Marks, Inspection. Are certain marks cut on cannon to show the number of the gun, the name of the founder, name of inspector, weight of the piece, etc. Condemned shot are also marked. See [Inspection of Projectiles].
Marksman. One who is skillful to hit a mark; one who shoots well.
