=Illyricum=, or =Illyria=. Is the Roman name of a country whose limits

in ancient times varied considerably. It was inhabited by a savage

tribe, who were much addicted to piracy and robbery. In 359 B.C. Philip

of Macedon conquered the eastern portion of the country, now Albania,

and it was incorporated with Macedonia. The Illyrians were brought into

a collision with the Romans on account of their piracy, which led to

their subjugation about two centuries before the Christian era. They

made numerous efforts to shake off the Roman yoke, but were always

defeated, and the country became a most important province of the Roman

empire, comprising the territory represented in modern times by Croatia,

Dalmatia, Herzegovina, Montenegro, nearly all Bosnia, and a part of

Albania. On the division of the Roman empire, it shared in the

vicissitudes that followed that act. A decree of Napoleon, on October

14, 1809, gave the name of Illyrian provinces to Carniola, Dalmatia, and

other countries from the Adriatic Sea to the Save, then belonging to the

French empire. At his fall these provinces were united as a kingdom to

the Austrian empire, and some alterations were made in its boundaries,

especially by the restoration to Hungary of what had formerly belonged

to it, and the annexation of the whole of Carinthia.

=Ilmenau.= A town of Saxe-Weimar, on the Ilm, 18 miles west from Weimar.

A battle was fought by the united forces of the Russians and Saxons

against the Swedes near this town in 1706.

=Imbannered.= Furnished with banners.

=Imbellic.= Not warlike or martial. This term is now obsolete.

=Imbody.= See EMBODY.

=Imbrued=, or =Embrued=. An expression used in heraldry to signify

bloody, or dropping with blood. Weapons thus blazoned are drawn with

drops of blood falling from them.

=Imeritia.= Formerly an independent Transcaucasian territory, now part

of the government of Kutais. Its history as an independent dominion

commenced from about the beginning of the 15th century, and was long

marked by internal dissensions. In 1745, Solomon I. was proclaimed, but

his nobles revolting shortly after, and aided by the Turks, dethroned

him. Solomon applied for help to Russia, and in 1769, Count Todtlen, at

the head of a Russian force, entered Emeritia, restored the king, and

drove back the Turks. The civil dissensions of this province, however,

continued, and at last, in 1810, after having long acknowledged

allegiance to Russia, it was formally incorporated in, and proclaimed a

province of that empire.

=Immailed.= Wearing mail or armor; clad in armor. This term is now

obsolete.

=Immartial.= Not martial; not warlike. This term is now obsolete.

=Immortals.= In antiquity, the name of a body of 10,000 troops,

constituting the guard of the king of Persia; so called because they

were always of the same number; for as soon as any of them died, the

vacancy was immediately filled up. They were distinguished from all the

other troops by the richness of their armor, and still more by their

bravery. The same term was applied to the life-guards of the Roman

emperors.

=Imola.= A fortified town of Ravenna, a province of Italy, on a small

island in the river Santerno; it is defended by a strong castle. This

town was founded by the Lombards on the ruins of Forum Cornelii,

destroyed by Justinian, and was afterwards successively held by

different chiefs who ruled in Central Italy. Julius II. annexed it to

the States of the Church, but it was delivered from the papal yoke when

Ravenna declared for annexation to Sardinia in 1859.

=Impact.= In gunnery, the single instantaneous blow or stroke of a body

in motion against another either in motion or at rest.

=Impale.= In heraldry, to arrange two coats of arms side by side in one

of husband and wife, the husband’s arms occupying the dexter, or right

side, and the wife’s the sinister, or left side, of the escutcheon.

=Impedimenta.= The accompaniments to an army received from the Romans

the name of impedimenta. They consist in transportation of munitions,

equipments, provisions, hospital supplies, tents, engineering tools,

bridge equipage, and boats, baggage, cooking utensils, etc., necessary

for the use of an army moving against an enemy. This requires the use of

large numbers of wagons and of draught animals, or shipping, and

necessarily impedes the movement of an army. See BAGGAGE.

=Impenetrable.= Incapable of being penetrated or pierced, not admitting

the passage of other bodies, not to be entered; as, an impenetrable

shield.

=Imperator.= An old Roman title signifying commander, which was applied

to the rulers of provinces, consuls, pro-consuls, etc., or to anybody

who had an _imperium_ assigned him. After a victory the Roman soldiers

frequently saluted their commander by this title.

=Imperial Guards.= See GUARDS, IMPERIAL.

=Imperialists.= This word was chiefly applied to the subjects of, or

forces employed by the house of Austria, when opposed to the troops of

other German powers.

=Imperil.= To bring into peril, to endanger.

=Impetuous.= Rushing with force and violence, moving with impetus,

furious, forcible; as, the troops went pouring forward with impetuous

speed.

=Impetus.= In gunnery, the altitude through which a heavy body must fall

to acquire a velocity equal to that with which a ball is discharged from

a piece.

=Implement.= Whatever may supply a want, especially an instrument or

utensil as supplying a requisite to an end; as, the implements of war.

=Implements, Equipments, and Machines.= In artillery, the two former are

employed in loading, pointing, and firing cannon, and in the mechanical

manœuvres of artillery carriages, the latter to mount and dismount

cannon from their carriages, and to transport artillery material from

one part of a work to another. The implements for loading cannon are,

(1) The _rammer-head_, a short cylindrical piece of beech or other tough

wood, fixed to the end of a long stick of ash, called a _staff_,

employed to push the charge to its place in the bore or chamber of a

cannon. (2) The _sponge_, a _woolen_ brush attached to the end of a

staff, for the purpose of cleaning the interior of cannon and

extinguishing any burning fragments of the cartridge that may remain

after firing. In the field and mountain services, the rammer-head and

sponge are attached to the opposite ends of the same shaft; in the siege

and sea-coast services, they are attached to separate staves, except for

howitzers, in which they are combined. (3) The _ladle_, a copper scoop

attached to the end of a staff for the purpose of withdrawing the

projectile of a loaded piece. (4) The _worm_, a species of double

cork-screw attached to a staff, used in field and siege cannon to

withdraw a cartridge. (5) The _gunner’s haversack_ (which see). (6) The

_pass-box_, a wooden box closed with a lid and carried by a handle

attached to one end. In siege and sea-coast service, where the cartridge

is large, it takes the place of the haversack. (7) The _tube-pouch_ or

_primer-pouch_, a small leather pouch attached to the cannoneer by a

waistbelt. It contains the friction-tubes, lanyard, priming-wire,

thumb-stall, etc. (8) The _budge-barrel_ (which see). (9) The

_priming-wire_, used to pick a hole in a cartridge for the passage of

the flame from the vent. (10) The _thumb-stall_, a buckskin cushion

attached to the thumb or finger to close the vent in sponging and

loading. (11) The _fuze-setter_, a brass drift for driving a wooden fuze

into a shell. (12) The _fuze-mallet_, made of hard wood, and used in

connection with the setter. (13) The _fuze-saw_, a 10-inch tenon saw for

cutting wooden or paper fuzes to the required length. (14) The

_fuze-gimlet_, sometimes employed in place of the saw to open a

communication with the fuze composition. (15) The _fuze-auger_, an

instrument for regulating the time of burning of a fuze by removing a

certain portion of the composition from the exterior. For this purpose

it has a movable graduated scale, which regulates the depth to which the

auger should penetrate. (16) The _fuze-rasp_, a coarse file employed in

fitting a fuze-plug to a shell. (17) The _fuze-plug reamer_, used to

enlarge the cavity of a fuze-plug after it has been driven into a

projectile, to enable it to receive a paper fuze. (18) The _shell-plug

screw_, a wood screw with a handle, used to extract a plug from a

fuze-hole. (19) The _fuze-extractor_, worked by a screw, and is a more

powerful instrument than the preceding; it is used for extracting wooden

fuzes from loaded shells. (20) The _fuze-wrench_, made in the form of a

cross or T-shaped, to unscrew percussion fuzes. (21) The

_mortar-scraper_, a slender piece of iron with a spoon at one end and a

scraper at the other, for cleaning the chamber of a mortar. (22) The

_gunner’s sleeves_, made of flannel or serge; they are drawn over the

coat-sleeves of the gunner to prevent them from being soiled while

loading a mortar. (23) The _funnel_, made of copper, and used in pouring

the bursting charge into a shell. (24) The _powder-measures_, made of

copper, of cylindrical form, and of various sizes, for the purpose of

determining the charges of shells and cannon by measurement. (25) The

_lanyard_, a cord, one end of which has a small iron hook, and the other

a wooden handle. It is used to explode the friction-tubes with which

cannon for the land service are now fired. (26) The _gunner’s gimlet_

and _vent-punch_, used in boring out the vent when it becomes foul. (27)

_Gunner’s pincers_ (which see). (28) The _shell-hooks_, an instrument

made to fasten into the ears of a shell, for the purpose of lifting it

to the muzzle of the piece. (29) The _tow-hook_, in field service, used

in unpacking ammunition and taking projectiles from the chest. The

implements for pointing are: the _gunner’s level_, _gunner’s quadrant_,

the _breech-sight_, the _pendulum-hausse_, and _elevating arc_. (See

appropriate headings.) The _tangent-scale_, a brass plate, the lower

edge of which is cut to the curve of the base-ring of the piece, and the

upper formed into offsets which correspond to differences of elevation

of a quarter of a degree. It is used in pointing by placing the curved

edge on the base-ring, with the radius of the offset corresponding with

the highest point of the ring, and sighting over the centre of the

offset, and the highest point of the swell of the muzzle. The principal

manœuvring implements are: the _trail handspike_, the _manœuvring

handspike_, the _shod handspike_, the _truck handspike_, the _roller

handspike_ (see HANDSPIKE); the _prolonge_, a stout rope used to connect

the lunette of the carriage and pintle-hook of the limber to move the

piece short distances without limber; the _sponge-bucket_, made of

sheet-iron, for washing the bore of the piece; the _tar-bucket_, also

made of sheet-iron, for carrying grease for the wheels; the _watering

bucket_, made of sole-leather, for watering the horses; the

_water-buckets_, made of wood and bound with iron hoops. These are of

two kinds,--one for the traveling-forge, and the other for the service

of garrison batteries. The _drag-rope_, used when necessary to employ a

number of men in hauling loads, or extricating a carriage from a

difficult part of the road. It has a hook at one end, a loop at the

other, and six wooden handles placed about 4 feet apart. The _men’s

harness_, similar to the drag-rope, except that the rope is stouter, and

the handles are replaced by leather loops which pass over the shoulders

of the men, to enable them to exert their strength to advantage. The

_bill-hook_, or hand-bill, used for cutting twigs. The _screw-jack_, a

lifting-machine composed of a screw worked by a _movable nut_ supported

on a _cast-iron stand_. It is used in greasing carriage-wheels.

Artillery machines comprise the _gin_ (see GIN), the _sling-cart_ (see

HAND-SLING-CART), the _casemate truck_, the _hand-cart_ (see HAND-CART),

the _lifting-jack_, and the _lever-jack_. The casemate truck is composed

of a stout frame of wood mounted on three barbette traverse-wheels, and

is employed to move cannon and carriages through posterns and along

casemate galleries. The lifting-jack is a small but powerful screw,

worked by a geared nut. It is useful when the space for manœuvring is

small, and the number of men limited. If the weight to be raised is

sufficiently high, the lifting power is applied at the top; if it be

low, it is applied at the foot. The lever-jack is another but less

powerful apparatus for lifting. It consists of a _lever_ of wood resting

on a _bolt_, which passes through holes in two _uprights_. The height of

the bolt is varied by passing it through different holes in the uprights

(eight in number), and the power of the lever is regulated by a notched

piece of cast iron screwed to the under side of the lever.

=Implements, Re-loading.= See RE-LOADING IMPLEMENTS.

=Impregnable.= Not to be stormed, or taken by assault; incapable of

being reduced by force; able successfully to resist attack; as, an

impregnable fortress.

court-martial in any case where the court may have discretionary

authority. General, garrison, and regimental courts-martial may sentence

soldiers to imprisonment, solitary or otherwise, with or without hard

labor, for various offenses enumerated in the Articles of War. A

garrison or regimental court-martial, in awarding imprisonment, is

limited to a period not exceeding thirty days. When a court awards

solitary imprisonment as a punishment, it is necessary that the words

“solitary confinement” should be expressed in the sentence. The legal

imprisonment in the United States is confinement, solitary confinement,

and confinement on bread and water; confinement on bread and water shall

not extend over fourteen days at a time, with intervals between the

periods of such confinement not less than such periods, and not

exceeding eighty-four days in any one year.

=Impulse.= The act of impelling, or driving onward with sudden force;

impulsion; the action of a force so as to produce motion suddenly, or

without appreciable loss of time. Also sudden motion exciting to action;

hasty inclination; influence acting unexpectedly, or with momentary

force; impression; instigation; as, the troops moved forward with one

impulse.

=In Battery.= The position of field-guns when unlimbered and prepared

for action. Also applied to heavy guns when in the firing position; also

the command for the movement in both cases. Heavy guns are “from

battery” when in the loading position.

=In Gear.= A command in the service of heavy guns, to cause the

eccentrics of the truck-wheels to be thrown in gear. Also refers to the

position of the eccentrics when the command is executed.

=In Line.= Refers to the formation of troops when posted, or marching,

with extended front.

=Inaccessible.= A general term for any distance or height which cannot

be approached for any military purposes.

general court-martial, and rendered incapable of ever serving his

country in either a civil or military capacity.

=Incendiary Compositions.= Used to set fire to buildings, shipping,

etc., have been known and used from the earliest times. Greek fire

(which see) was extensively used in the 7th century. Among modern

incendiary compositions are _fire stone_, sometimes called _rock fire_,

and _Valenciennes composition_ (which see).

=Incendiary Shells.= Are shells containing incendiary compositions. See

CARCASS for modern example.

=Incensed=, or =Animé=. An epithet applied in heraldry to panthers or

other wild beasts borne with flames issuing from their mouth and ears.

=Incidence, Angle of.= In projectiles, the angle which the line of

direction of the projectile makes with the surface of the obstacle on

which it impinges.

=Inclination.= In gunnery, the inclination of a plane is the angle it

makes with the horizon either above or below.

=Inclination of the Grooves.= In a rifle is the angle which the tangent

to the groove at any point makes with the element of the bore passing

through the point. The tangent of the angle, which may be taken as a

measure of the inclination, is equal to the circumference of the bore

divided by the length of bore corresponding to one revolution of the

spiral. See TWIST.

=Incline.= To gain ground to the flank, as well as to the front.

Inclining is of great use in the marching of the line in front, to

correct any irregularities that may happen. It is equivalent to the

quarter facing and to the oblique marching of the infantry. It enables

you to gain the enemy’s flank without exposing your own, or without

wheeling or altering the parallel front of the company.

=Inclose.= To surround; to shut in; to confine on all sides; to include;

to shut up; to encompass; as, to inclose a fort or an army with troops;

to inclose a town with walls.

etc., from which the enemy may be harassed, or which is necessary to his

security.

=Incompetent.= Incapable; unfit; unequal. No officer, be his situation

what it may, can be said to be competent to command who is not only

willing and able to follow orders himself, but will likewise see them

strictly adhered to by others; whose mind is not superior to

partialities, and whose judgment is not equal to discern real merit from

ignorant assumption.

=Incorporate, To.= To add a smaller body of forces to a larger, and to

mix them together. Independent companies are said to be incorporated,

when they are distributed among different regiments; regiments among

brigades, etc.

=Incorporation.= In the manufacture of gunpowder, is the thorough mixing

of the three ingredients--nitre, sulphur, and charcoal,--a very

important operation. The process should be so complete that the smallest

particle of the gunpowder should contain each ingredient in proper

proportion.

=Increasing Twist.= A term applied to rifle grooves, the inclination of

which increases from the breech to the muzzle. In many guns the grooves

begin at the front of the chamber, without inclination.

damage, or injury sustained.

=Indent, To.= A word particularly made use of in India for the dispatch

of military business. It is of the same import and meaning as _to draw

upon_. It likewise means an order for military stores, arms, etc.; as,

an indent for new supplies, etc.

=Indented.= In heraldry, one of the partition lines of the shield,

similarly notched to dancetté, but with notches much smaller, and not

limited in number.

=Indented Line.= In fortification, is a serrated line, forming several

angles, so that one side defends another. The faces are longer than the

flanks. Indented lines are used on the banks of rivers, where they enter

a town. The parapet of the covered way is also often indented.

=Independence, Declaration of.= The solemn declaration of the Congress

of the United States of America, on July 4, 1776, by which they formally

renounced their subjection to the government of Great Britain.

=Independent.= In a military sense, is a term which distinguishes from

the rest of the army those companies which have been raised by

individuals for rank, and were afterwards drafted into corps that were

short of their complement of men. _Independent company or troop_, is one

that is not incorporated into any regiment.

=India=, or =Hindostan=. An extensive region of Southern Asia,

celebrated during many ages for its riches and natural productions. The

Hindoo histories ascribe the origin of the people to a period ages

before the ordinary chronologies. A race of kings is mentioned as

reigning 2300 B.C. Several ancient nations, particularly the Tyrians and

Egyptians, carried on commerce with India. It was partially conquered by

Darius Hystaspes, who formed an Indian satrapy, 512 B.C., and by

Alexander, 327 B.C. The authentic history of Hindostan commences with

the conquests of Mahmoud Ghuzni, 1004. For further history of India, see

BENGAL, CALCUTTA, MADRAS, etc.

=Indian File.= Single file; arrangement of persons in a row following

one after another; the usual way among Indians of traversing woods,

etc.

=Indian Fortification.= The entrance into an East Indian fortification

is through a large and complicated pile of buildings, projecting in the

form of a parallelogram from the main rampart; and, if the city has two

walls, it projects beyond them both. This building consists of several

continued terraces, which are of the same height as the main rampart,

and communicate with it; the inward walls of these terraces form the

sides of an intricate passage, about 20 feet broad, which leads by

various short turnings, at right angles, through the whole pile to the

principal gate that stands in the main rampart. This is the general

outline of the old Indian fortifications.

=Indian Military Force.= The East Indian military service, like the

civil service, has been undergoing a thorough reorganization, consequent

on the great mutiny, and the transfer of the government of the country

from the East India Company to the crown. In 1857, at the outbreak of

the mutiny, the Indian army consisted of about 277,000 men, of whom

45,000 were Europeans and 232,000 natives. During the mutiny the native

army of Bengal was almost entirely broken up. Fifteen regiments of

regular native infantry, the local infantry, the Gurka and irregular

line regiments, eight regiments of irregular cavalry, and the sappers

and miners, were all that remained at the close of 1860 of the old

native army of Bengal. The Indian army in 1867 numbered 183,148 men;

61,498 being Europeans, and 121,650 Indian forces. The police, civil and

military, forms an important force, and is to a great extent taking the

place of the regular army. In Bengal, for instance, the military police

includes ten battalions of infantry each 700 strong; three squadrons of

cavalry, and some local levies; in all about 10,000 men, of various

races, with 40 European officers. The whole police force of India has

been reorganized on one uniform system, with a central organization of

its own in each presidency.

=Indian Territory.= A large extent of territory, which originally

belonged to the Louisiana purchase, lying north by west of that State.

It was set apart for the use of Indians, many tribes of whom have from

time to time been removed to it, and have wonderfully improved in the

arts of civilized life.
