=Insurgents.= Soldiers or people generally in a state of insurrection.

The term, however, admits of one exception. Hungarian insurgents

(_Insurgenten die Ungarischen_) mean the Hungarian militia, called out

or summoned by general proclamation, as under the old feudal system.

=Insurrection.= A rising against civil or political authority; the open

and active opposition of a number of persons to the execution of law in

a city or state; a rebellion; a revolt.

=Intenable.= Incapable of being held; untenable; not defensible; as, an

intenable fortress.

=Intendant=, or =Intendant Militaire=. An officer in the French army

charged with the organization and direction of all the civil services

attending a force in the field. The officers acting under his orders are

those in charge of all the finance services, the provisions, stores,

hospitals, artillery train, and transport departments, besides the

interpreters, guides, and such like temporary services. The

_intendant-en-chef_ of an army is the representative of the minister of

war; and, short of superseding the general’s orders, can exercise, in

case of need, all the functions of that high officer of state. The

intendance is divided into intendants, ranking with general officers,

sub-intendants with colonels, and assistant-intendants with majors;

besides these there are cadets, who receive no pay, and constitute a

probationary grade.

=Intercept.= To interrupt communication with, or progress towards; to

cut off; as, to intercept the march of an army.

=Intercombat.= A combat between.

=Interior.= A word of varied application; as, the _interior flanking

angle_ is formed by the curtain and line of defense. _Interior radius_

is that part of an _oblique radius_ extending from the centre of the

polygon to the centre of the bastion. _Interior side_ is the line of the

curtain produced to the two oblique radii of the front, or a line drawn

from the centre of one bastion to that of the next.

=Interior Form of Cannon.= The interior of cannon may be divided into

three distinct parts: 1st, the _vent_, or channel which communicates

fire to the charge; 2d, the _seat of the charge_, or chamber, if its

diameter be different from the rest of the bore; 3d, the _cylinder_, or

that portion of the bore passed over by the projectile. See also GROOVES

FOR RIFLE CANNON.

=Interior Guards.= Are police guards, guards of property, etc., who are

liable to come in contact with the enemy.

=Interior Slope.= Is the inclination towards the inner part of a work

which is given to the earth forming the rampart or parapet. _Interior

crest_ is the crest of the interior slope.

=Interval.= In military dispositions and manœuvres, any given distance

or space. In tactics the term is used to signify taken parallel to the

front, as opposed to distance or space perpendicularly to the front.

_Interval between two battalions_ is the space which separates them when

they are drawn up for action or when they are encamped. This space is

generally wide enough to admit the march of another regiment; that is to

say, it is equal to the extent of its front when in line. _Interval

between the line and the camp_ comprehends the space which lies between

the camp and the line of intrenchments. It is generally from 180 to 200

toises in breadth; so that the different sections of troops which are

necessary for the security of the camp, may have room to move in, while

sufficient ground is left in rear for troops to pass and repass as

occasion may require. The same observation holds good with respect to

contrevallation.

=Intrench.= Is to make secure against the attack of an enemy by digging

a ditch or trench, etc. _To intrench upon_, to invade, to make

encroachments upon the property or territories of another.

=Intrenched Camp.= A large space capable of containing an entire army,

surrounded by works of fortification. Frequently an intrenched camp

joins a fortress, in which case it is protected by permanent works of

considerable strength--detached forts, for instance.

=Intrenching Tool.= An implement used for intrenching. In view of the

deadly fire of modern small-arms it is a matter of great importance that

the soldier should be able to get cover. For this reason it has been

proposed to make an intrenching tool a part of the soldier’s equipment.

In the United States army a combination bayonet and intrenching tool is

used. See TROWEL BAYONET.

=Intrenchment.= Is generally a ditch or trench with a parapet. The earth

removed to form the ditch is used to construct the parapet. Fascines,

with earth thrown over them, gabions, hogsheads, or bags filled with

earth, are often employed to revet or strengthen the work when the earth

is loose or sandy. _Intrenchments of armies_ are the whole works or

obstacles by which an army or large body of troops cover themselves for

their defense.

=Intrepidity.= An unqualified contempt of death; an indifference to

fortune as far as it regards personal safety; a fearlessness of heart,

and a daring enterprise of mind.

=Inundation.= The act of letting water into a country so that it shall

be overflowed, to prevent the approach of an enemy. It is among the most

considerable of the various methods which have been devised for

impeding the approach to a field-work, or indeed, any fortification.

=Invade, To.= To make a forcible or clandestine entry into the territory

of another state; to pass the regular line of frontier of any country,

in order to take possession of the interior.

=Invalid.= A soldier who has been wounded, or has suffered in his

health, and in consequence of his good conduct has been recommended to a

certain provision for life. Chelsea Hospital is the place allotted for

the reception of such objects of public gratitude and benevolence in

England; the Soldiers’ Home, in Washington, D. C., in the United States,

and the Hôtel des Invalides, at Paris, France. In England numbers of

invalids are, however, allowed to reside where they choose, and are then

known as “out-pensioners.”

=Invalides.= Wounded veterans of the French army, maintained at the

expense of the State. See HÔTEL DES INVALIDES.

=Invaliding.= Signifies the return home, or to a more healthy climate,

of soldiers or sailors whom wounds or the severity of foreign service

has rendered incapable of active duty. The man invalided returns to his

duty as soon as his restored health justifies the step.

=Invasion.= In war, is the entrance or attack of an enemy on the

dominions of another.

=Inventory of Effects of Deceased Officers and Soldiers.= See APPENDIX,

ARTICLES OF WAR, 125, 126.

=Inverness.= A royal burgh of Scotland, capital of a county of the same

name, situated on both sides of the river Ness. It was a city of the

Picts up to 843; taken by Edward I.; retaken by Bruce, 1313; burnt by

the Lord of the Isles, 1411; taken by Cromwell, 1649; and by Prince

Charles Edward in 1746. The latter was defeated at Culloden, about 5

miles from Inverness, April 16, 1746.

=Inversion.= A movement in tactics by which the order of companies in

line is inverted, the right being on the left, the left on the right,

and so on.

=Invest.= To invest a place is to seize upon all the avenues leading to

a town or fortress. On the occasion of an investment, the hostile troops

are distributed on the principal commands, to prevent any succor from

being received by the garrison, and to keep the ground until the rest of

the army, with the artillery, can arrive to form a regular siege. To

invest a place is, in fact, to take preparatory measures for a blockade

or close siege.

=Invincible.= Incapable of being conquered or overcome; unconquerable;

insuperable; as, an invincible army, etc.

=Inwall.= To inclose or fortify with a wall.

=Iona=, =Icolmkill=, or =Hii=. The most famous of the Hebrides, in

Argyle Co., Scotland. It is about 3 miles long, and varies in breadth

from a mile to a mile and a half. It was founded by Saint Columba, a

native of Ireland, in the 6th century, and long remained the chief seat

of learning and the centre of missionary enterprises undertaken by the

Culdees. In 795, 802, 806, 825, and 986 the island was ravaged by

Norsemen, by whom its monks were martyred in the three latter dates.

=Ionia.= In Asia Minor. About 1040 B.C., the Iones, a Pelasgic race,

emigrated from Greece, and settled here and on the adjoining islands.

They were conquered by the great Cyrus about 548 B.C.; revolted in 504,

but were again subdued. After the victories of Cimon, Ionia became

independent and remained so till 387, when it was once more subjected to

Persia. It formed part of the dominions of Alexander and his successors;

was annexed to the Roman empire, and conquered by the Turks.

=Ionian Islands.= A group of islands running round the west coast of

Epirus, and west and south of Greece. After the division of the Roman

empire these islands were included in the eastern half, and so continued

till 1081, when the Duke of Calabria took possession of them. From this

time they underwent a continual change of masters till the commencement

of the 15th century, when they by degrees came into possession of the

Venetians, who in 1797 ceded them to France. They were seized by Russia

and Turkey in 1800, by France in 1807, by Great Britain in 1809, and

November 15, 1815, they were formed into a republic under the

protectorate of the latter power. In May, 1864, they were formally

annexed to Greece.

=Ionie Indians.= A tribe of aborigines allied to the Caddos, who resided

in Texas, and were generally peaceable and friendly.

=Iowa.= One of the Central States of the United States, lying between

the Mississippi and Missouri Rivers. It originally formed a portion of

the Louisiana Territory; and permanent settlements commenced to be

formed in it about 1833; organized as a Territory in 1838, and admitted

as a State in 1846. During the civil war it contributed its full quota

of troops to the cause of the Union.

=Iowa Indians.= A tribe of aborigines of Dakota stock, who inhabited the

State which now bears their name. They were closely allied to the Sacs

and Foxes.

=Ipsara=, or =Psara=. A small island in the Grecian Archipelago, west of

Scio; belongs to Turkey. It was taken by the Turks in 1824.

=Ipsus.= A town of Phrygia, in Asia Minor. Here in 301 B.C., a battle

was fought between Antigonus, king of Asia, and the forces of Cassander,

Lysimachus, Ptolemy, and Seleucus, which resulted in the defeat and

death of Antigonus.

=Ipswich.= The chief town of the county of Suffolk, England, situated on

the Orwell. This town was destroyed by the Danes about 1000.

=Ireland.= Anciently named _Ierne_ and _Hibernia_, is said to have been

first colonized by Phœnicians. Some assert that Partholani landed in

Ireland about 2048 B.C.; that the descent of the Damnonii was made about

1403 B.C.; and that this was followed by the descent of Herber and

Heremon, Milesian princes, from Galicia, Spain, who conquered Ireland,

and gave to the throne 171 kings. The Danes and Normans invaded Ireland

in 795; but were totally defeated by Brian Boriomhe at Clontarf, April

23, 1014. In 1172, King Henry II. of England invaded Ireland with a

formidable armament, and received homage from several of the minor

native chiefs, and from the chief Norman adventurers, granting to the

latter charters authorizing them, as his subjects, to take possession of

the entire island in his name; which they partially succeeded in

accomplishing. Subsequently the authority of the English crown became

limited to a few towns on the coast, and the district termed “the Pale,”

comprising a small circuit about Dublin and Drogheda. Henry II. received

the title of “king of Ireland” in 1541, by an act passed by the

Anglo-Irish Parliament in Dublin; and about the same period, some of the

native princes were induced to acknowledge him as their sovereign, and

to accept peerages. The attempts of the English government to introduce

the reformed faith stirred up dissensions in Ireland. Among the first to

revolt was the Earl of Desmond, after whose death, in 1583, his vast

estates in Munster were parceled out to English settlers. Soon after the

chief clans of Ulster took up arms; and in opposing them, the forces of

Queen Elizabeth, commanded by officers of high military reputation,

encountered many reverses, the most serious of which was that in 1598 at

the battle of the Yellow Ford, where the English army was routed and its

general slain. Philip III. of Spain, at the solicitation of the Irish

chief, dispatched a body of troops to their assistance in 1601, which

landed in the extreme south, instead of in the north, as had been

expected, were unable to effect anything, and were constrained, to

surrender. Although Elizabeth was supported by numbers of native Irish,

the northern chiefs, O’Neill and O’Donnell, held out till the queen’s

government came to terms with them in 1603, recognizing them as earls of

Tyrone and Tirconnell. In 1608 these noblemen having apprehensions for

their personal safety quitted Ireland, and retired to the continent.

Their withdrawal enabled James I. to carry out that project of parceling

out the north of Ireland to Protestant Scotch and English settlers. The

Irish took advantage of the contentions in England to rise in

insurrection (1641) and massacre the Protestants. It is believed that

nearly 40,000 fell victims to their fury. The country continued in a

state of anarchy till 1649. when Cromwell overran it. At the revolution

the native Irish generally took the part of James II., the English and

Scotch “colonists” that of William and Mary; and the war was kept up for

four years (1688-1692). The Irish again rebelled in 1798, and were not

suppressed until 1800. Ireland was incorporated with England and

Scotland in 1801. Several insurrections have taken place since the

latter date but were quickly suppressed. For important military events

in Ireland, see separate articles.

=Irish Brigade.= A body of men who followed the fortunes of James II.,

and were formed into regiments under the monarchy of France.

=Iron Cross.= A Prussian order of knighthood, instituted on March 10,

1813, by Frederick William III., and conferred for distinguished

services in the war which was then being carried on. The decoration is

an iron cross with silver mounting. The grand cross, a cross of double

the size, was presented exclusively for the gaining of a decisive

battle, or the capture or brave defense of a fortress. It was revived by

William I. in the Franco-Prussian war, and awarded by him to his son for

his victory at Weissembourg, August 4, 1870.

=Iron Crown.= The crown of the ancient Lombard kings; is a broad band of

gold set with jewels, within which is a thin plate or fillet of iron,

and is declared by tradition to have been hammered from one of the nails

of the true cross. It has been used at the coronation of 34 different

monarchs, including Charlemagne, Henry VII. of Germany, Charles V., and

Napoleon. After the peace of Vienna in 1866, the crown was presented by

the emperor of Austria to Victor Emmanuel, king of Italy.

=Iron Ores.= _Character of Pig-iron._--Ores suitable for “gun-metal”

should be reduced in the smelting-furnace, with charcoal and the warm

blast, varying from 125° to 300° Fahr., depending upon the ore used.

Iron thus made, or pig-iron, should be soft, yielding easily to the file

and chisel; the appearance of the fracture should be uniform, with a

brilliant aspect, dark gray color, and medium-sized crystals. _Character

of Gun-metal._--When remelted and cast into cannon, it should approach

that degree of hardness which resists the file and chisel, but not so

hard as to be bored and turned with much difficulty. Its color should

be a bright, lively gray; crystals small, with acute angles, and

sharp to the touch; structure uniform, close, and compact.

_Magnetite._--_Octahedral Iron Ore._--Color iron-black. Streak black.

Brittle. The black streak and magnetic properties distinguish this

species from the following: _Specular Iron Ore._--_Hematite._--Often

massive granular; sometimes lamellar or micaceous. Also pulverulent and

earthy. Color, dark steel-gray or iron-black, and often when

crystallized having a highly splendid lustre; streak-powder cherry-red

or reddish-brown. The metallic varieties pass into an earthy ore of a

red color, having none of the external characters of the crystals, but

perfectly corresponding to them when they are pulverized, the powder

they yield being of a deep red color, and earthy or without lustre.

Sometimes slightly attracted by the magnet. _Limonite._--_Brown Iron

Ore._--Usually massive, and often with a smooth botryoidal or

stalactitic surface, having a compact fibrous structure within. Also

earthy. Color, dark brown to ochre-yellow; streak, yellowish-brown to

dull yellow. Lustre, sometimes sub-metallic; often dull and earthy; on a

surface of fracture frequently silky. _Spathic Iron._--_Carbonate of

Iron._--_Chalybite._--Usually massive, with a foliated structure,

somewhat curving. Sometimes in globular concretions or implanted

globules. Color, light grayish to brown; often dark brownish-red, or

nearly black on exposure. Streak, uncolored. Lustre, pearly to vitreous;

translucent to nearly opaque.

=Irons.= Fetters or instruments made of iron, with which a prisoner is

shackled. _To be put in irons_, is to be handcuffed and confined in

fetters.

=Ironsides.= A strong man. A cuirassier;--applied also to Cromwell’s

cavalry.

=Iroquois=, or =Six Nations=. The name given by the French to the Indian

confederacy of the Mohawks, Oneidas, Onondagas, Cayugas, and Senecas, to

which were afterwards added the Tuscaroras, after being driven from

their hunting-grounds in North Carolina. This once formidable

confederacy is now nearly extinguished, but remnants of it are still

found scattered through the State of New York.

=Irregular.= Not regular; not according to common form or rules; as, an

irregular building or fortification. See FORTIFICATION, IRREGULAR.

=Irregular Cavalry.= A term now almost obsolete. It applied a few years

ago to regiments of horsemen raised under certain conditions in the East

Indies. These conditions were that each man should provide his own

horse, arms, accoutrements, and clothing, receiving in return a monthly

sum, which also included his pay. To these regiments only three English

officers were appointed, the other officers being natives. These

regiments are still paid in the same way, but they are clothed, armed,

and equipped in a uniform manner; the number of British officers is

increased, and they are no longer styled irregular cavalry.

=Irregularity.= A violation of the customs of service,--a delinquency

which is subject to censure but not serious enough to be brought before

a court-martial.

=Irun.= A town of Spain, near the left bank of the Bidassoa. It is a

place of great antiquity, having been in existence in the time of the

Romans. The Carlists were defeated by the British Legion, under Gen. Sir

de Lacy Evans, in the battle of Irun, May 16, 1837.

=Isabella the Catholic, Order of.= A Spanish order of knighthood,

founded by Ferdinand VII., March 24, 1815, as a reward of loyalty, for

the defense of the possessions of Spanish America. At present, it is

conferred for all kinds of merit. The sovereign is the head of the

order, which is divided into the three classes of Grand Crosses,

Commanders, and Knights.

=Isauria.= A province in Asia Minor, the inhabitants of which were a

wild and semi-barbarous race, who lived by rapine and plunder. The

Romans surrounded Isauria with a chain of fortresses, but the Isaurians

broke through them and remained as untamable as before. Under the

empire, army after army was sent against Isauria, which stood to Rome,

and afterwards to Constantinople, very much in the relation that

Circassia now does to Russia. In the 8th century their national vanity

was gratified by a countryman of their own being appointed to the

throne. From this date they gradually ceased to be formidable.

=Ischia.= An island in the Gulf of Naples, 6 miles from the coast, and

17 miles west from Naples. In 1807, Ischia was taken by a British and

Sicilian force.

=Isernia.= A place in Southern Italy, on the west slope of the

Apennines, where the Sardinian general Cialdini defeated the

Neapolitans, October 17, 1860.

=Isle of France.= See MAURITIUS.

=Ismail=, or =Ismailov=. A strong town of Turkey in Europe, on the north

side of the Kilia arm of the Danube. This place was long in the

possession of the Turks; it was stormed by the Russians, under Suwarrow,

in 1790. It remained in the possession of Russia until 1856, when it was

restored to Turkey by the removal of the Russian frontier.

=Isolé= (_Fr._). This word is used among the French, to express any body

or thing which is detached from another. It is variously applied in

fortification. Thus a pavilion or a barrack which is not joined to any

other wall or building is called isolé, because it stands alone, and a

person may walk entirely round it. A parapet is also said to be isolé

when there is an interval of 4 or 5 feet existing between the rampart

and its wall; which interval serves as a path for the rounds.

=Ispahan.= A famous city of Persia, capital of the province of

Irak-Ajemi, situated on the Zendarud. In 1722 it was taken by the

Afghans, and in 1729 was retaken by Nadir Shah. It has fallen gradually

into decay.

=Issue.= Event; consequence; the ultimate result of any undertaking; the

termination of any contest. A term also applied to the distribution of

supplies; as, issue of rations, issue of clothing, etc., to troops.

=Issues.= In the British service, are certain sums of money which are,

at stated periods, given to public accountants for public service; and

for the honest distribution of which, every individual so intrusted is

responsible to Parliament. _Regimental issues_ are moneys paid by

regimental agents, acting under the authority of their respective

colonels, for regimental purposes.

=Issus.= An ancient city and seaport in Cilicia, in Asia Minor, close to

the frontier of Syria, on or near the head of the Sinus Issicus, now the

Gulf of Scanderoon. It was in the neighborhood of this city that

Alexander the Great annihilated the Persian army under Darius in 333

B.C. Here too was fought (194 A.D.), the bloody battle between Septimus

Severus and Pescennius Niger, by virtue of which the former became sole

master of the Roman empire. The exact site of Issus has not yet been

discovered.

=Istalif.= A town of Afghanistan, province of Cabul (Cabool). It was

taken and partly destroyed by the British in 1842.

=Italy.= A peninsula in the south of Europe. The invading Pelasgians

from Greece, and the aborigines (Umbrians, Oscans, and Etruscans),

combined, formed the renowned Latin race still possessing the southern

part of Europe. The history of Italy is soon absorbed into that of Rome,

founded 753 B.C. Previous to the 15th century it was desolated by

intestine wars and the interference of the German emperors; since then,

Spain, France, and Germany have struggled for the possession of the

country, which has been divided among them several times. Spain

predominated in Italy during the 16th and 17th centuries; but was

compelled to yield to the house of Austria at the beginning of the 18th

century. The victories of Bonaparte in 1797-98 changed the government of

Italy; but the Austrian rule was re-established at the peace of 1814. In

1848 the Milanese and Venetians revolted and joined Piedmont, but were

subdued by Radetzky. The hostile feeling between Austria and Piedmont

gradually increased till war broke out in April, 1859, in which the

Austrians were defeated, and the kingdom of Italy was re-established in

1861. Another war with Austria was declared in June, 1866, but peace was

signed in October, same year, and Venetia was ceded to Italy. For other

details, see ROME and the various Italian cities throughout this volume.

=Ithome.= A mountain fortress of Messenia, memorable for the defense

there made for many years against the Spartans in the first Messenian

war. It was afterwards the citadel of Messene, when that city was

founded by Epaminondas.
