Part 136
=Tertiate.= In gunnery, is to examine the thickness of the metal of a piece of artillery, in order to judge of its strength. This is usually done with a pair of caliper compasses. To _tertiate_ a piece of ordnance, is to examine the thickness of the metal, in order to judge of its strength, the position of the trunnions, etc.
=Teschen.= A town of Austrian Silesia, on the right bank of the Olsa, 38 miles east-southeast of Troppau. Here, in 1779, a treaty of peace was concluded between Maria Theresa and Frederick II., by which the dispute of the Bavarian Succession was brought to an end.
=Testri= (Northern France). Pepin d’Heristal, invited by malcontents, here defeated and captured Thierry III., king of Austrasia, and established himself as duke, 687.
=Testudo= (_Testude_). In ancient warfare, was a defensive arrangement of the shields, by means of which a body of men advancing against a wall for assault or mining, sought to protect themselves from the darts and weapons of the defenders. The men standing in close order, joined their shields above their heads, the edges overlapping, until the whole resembled the shell of a tortoise (_testudo_). The name was also applied to a machine moving on wheels, and roofed over, under which soldiers worked in undermining or otherwise destroying the walls in a siege.
=Tête-de-pont= (_Fr._). A field fortification in front of a bridge, to cover the retreat of an army across a river. They are generally formed in the shape of a redan, a system of crémaillères, horn- or crown-works, or portions of star-and-bastioned forts. In order to add to the defense of _tétes-de-pont_, reduits have been constructed within them, and the dimensions of their parapets are in general made larger than those of any other field-work, on account of their great importance. Sometimes the area inclosed by a _tête-de-pont_ is temporarily made use of as a depot for the stores necessary for the troops, in which case its tracing should present a strong point of defense, well provided with artillery, and affording in several points egress. The tracing which has been found the best for the passage of extensive trains of wagons and artillery, as well as columns of troops, is formed of crémaillères, extending in such a manner as to inclose a large area, and leaving behind each a passage well guarded and secured by second crémaillères, fronting the passage, and forming a second line. Additional strength will be given to _têtes_ of every kind by constructing small redans or batteries on the opposite side of the river, the fire from which may defend the ground in front of the salient, and flank the faces of the _tête-de-pont_.
=Tettenhall= (Staffordshire). It was probably at this place, then named Testenheal, that the Danes were defeated by the Anglo-Saxons sent against them by Edward the Elder, August 6, 910.
=Tetuan.= A seaport town on the north coast of Africa, 22 miles south of Ceuta. It was taken by the Spaniards under O’Donnell, February, 1860; and the treaty of Madrid, by which the city was evacuated in favor of the Spaniards, was concluded October 30, 1861.
=Teutoburg Forest.= Probably situated between Detmold and Paderborn, in North Germany, where Hermann, or Arminius, and the Germans defeated the Romans under Varus with great slaughter in the year 9. This defeat was regarded at Rome as a national calamity.
=Teutonic.= A term applied to a group of nations, as well as languages, forming an important division or stem of the Aryan family. Of the various tribes and nations spoken of as inhabiting Northern Europe in ancient times, it is often difficult to determine which were really of Germanic race, and which Celtic or Slavic. Of undoubted German nations who took part in the destruction of the Roman empire the most prominent were the Goths (which see), Lombards (which see), Vandals (which see), and Franks (which see). The term Teutonic is derived from _Teutones_, the name of a nation or tribe first mentioned by Pytheas, who wrote about 320 B.C., as then inhabiting a part of the Cimbric Chersonesus, or Jutland. For the next 200 years there is no further mention of the Teutones, that is, not until 113 B.C., when they appear in history as ravaging Gaul, and in conjunction with the Cimbri and Ambrones, threatening the very existence of the Roman republic. The Cimbri having gone into Spain, the Teutones and Ambrones were at length defeated by C. Marius in a great battle at Aqua Sextiæ, in Gaul, 102 B.C. A similar victory was gained by Marius in the following year over the Cimbri in the plains of Lombardy.
=Teutonic Knights.= One of the more celebrated of the military and religious orders to which the Crusades gave birth. The sufferings of the Christian soldiers at the siege of Acre excited the sympathy of certain merchants of Bremen and Lübeck, who rendered such important services by the erection of hospitals and otherwise, that Duke Frederick of Suabia, with the sanction of Pope Clement III. and the emperor Henry VI., enrolled them in an order of knighthood. The habit of the order was a white mantle with a black cross; and the knights took vows of poverty and chastity, which in later times were not very strictly interpreted. In the course of the 13th century, they were, with the sanction of the pope, engaged in a bloody war to enforce Christianity on the heathen nations inhabiting the southern shores of the Baltic, which resulted in the acquisition by the order of Prussia, Livonia, Courland, and other adjoining territories. Warriors from all parts of Europe in that and the following century joined their standard, including Henry IV. of England, accompanied by 300 attendant knights and men-at-arms. The conquests of the order raised it to the rank of a sovereign order, with a territory extending from the Oder to the Baltic, and embracing a population of between 2,000,000, and 3,000,000, the grand master having his seat at Marienburg, Prussia. The decline of the order began in the 15th century, and its fall was brought about partly by internal dissensions, and partly by the attacks of neighboring states. At the peace of Presburg in 1805, the emperor of Austria obtained the rights and revenues of the grand master, but in 1809 the order was abolished by Napoleon, its lands passing to the sovereigns in whose dominions they lay. The Teutonic order, however, still continues to preserve a titular existence in Austria.
=Tewkesbury.= A town of England, in Gloucestershire, on the Avon, and near its confluence with the Severn, 10 miles northeast from Gloucester. It is a very ancient town. Within a mile of it was fought (May 14, 1471) the famous battle of Tewkesbury, in which the Yorkists under Edward IV. and Richard III. inflicted a signal defeat on the Lancastrians.
=Texas.= One of the southwestern of the United States of America, is bounded on the southwest by Mexico, from which it is separated by the Rio Grande, and on the east by Arkansas and Louisiana. La Salle, the French explorer, erected a fort on Matagorda Bay, 1687. A Spanish settlement and mission was formed in 1690, but soon abandoned. In 1715, the country was settled by the Spaniards under the name of New Philippines, and several missions established; but the Camanche and Apache Indians, among the most warlike in America, and still the terror of the border settlements, hindered the progress of the country. In 1803, when Louisiana was ceded by France to the United States, Texas, claimed by both Spain and the United States, became a disputed territory. From 1806 to 1816, settlements were formed, and several attempts made to wrest the country from Spain. In one of these, in 1813, 2500 Americans and Mexicans and 700 inhabitants of San Antonio were killed. Mina, a Spanish refugee, gained some successes, but was defeated and shot. Lafitte, a Gulf pirate, made a settlement at Galveston in 1815, but it was broken up in 1821. In 1820, Moses Austin, an American, got a large tract of land from the Mexican government, and began a settlement, which rapidly increased; but many of the settlers were of so lawless a character, that in 1830 the government forbade any more Americans coming into Texas. In 1833, a convention of settlers, 20,000 in number, made an unsuccessful attempt to form an independent Mexican state; and in 1835 a provisional government was formed, Sam Houston chosen commander-in-chief, and the Mexicans driven out of Texas. Santa Anna, president of Mexico, invaded the country with an army of 7500, but after some successes was entirely routed at San Jacinto, April 21, and Texas became an independent republic, acknowledged in 1837 by the United States, and in 1840 by England, France, and Belgium. In December, 1845, Texas was annexed to the United States, but was invaded by Mexico, which had never acknowledged its independence. A war followed (1846-48) in which Mexico was defeated. In February, 1861, Texas joined the Secession, and furnished many soldiers and immense supplies to the Confederate armies. In February, 1866, the ordinance of secession was annulled, and in 1870 the reconstruction was completed, and regular civil government restored.
=Thanks.= Public acknowledgments for gallant actions.
=Thapsus= (ruins at _Demas_). A city on the east coast of Bycazena, in Africa Propria, where Cæsar finally defeated the Pompeian army, and finished the civil war, 46 B.C.
=Thasos= (now _Thaso_, or _Tasso_). An island in the Grecian Archipelago, belonging to Turkey, off the coast of Roumelia, 30 miles north-northeast of Mount Athos. It was at a very early period taken possession of by the Phœnicians on account of its gold mines. Thasos was afterwards colonized by the Parians, 708 B.C. Before the Persian conquest, the Thasians were one of the richest and most powerful tribes in the north of the Ægean. They were subdued by the Persians under Mardonius, and subsequently became part of the Athenian maritime empire. They revolted, however, from Athens in 465 B.C., and after sustaining a siege of three years were subdued by Cimon in 463. They were obliged to surrender to the Athenians all their possessions in Thrace, to destroy their fortifications, to give up their ships, and to pay a large tribute for the future. They again revolted from Athens in 411, and called in the Spartans, but the island was again restored to the Athenians by Thrasybulus in 407.
=Thaulache= (_Fr._). Armor and weapons of the ancient French, consisting of small shields (_rondelles_), and halberd or spear.
=Theatre of Operations.= See STRATEGY.
=Theatre of War.= The term for any extent of country in which war is carried on. It is synonymous with “seat of war.”
=Theban Legion.= According to tradition, was totally composed of Christians, and consequently submitted to martyrdom rather than attack their brethren during the persecution of the emperor Maximin, or sacrifice to the gods, about 286. Their leader was canonized.
=Thebes.= The name of a celebrated city; it was formerly the capital of Upper Egypt; it is now in ruins. It revolted against Ptolemy Lathyrus, and was captured after a siege of three years, in 82 B.C.
=Thebes= (now _Theba_). The chief city of Bœotia, in ancient Greece, was situated in a plain southeast of the Lake Helice, and northeast of Platææ. The territory of Thebes was called _Thebais_, and extended eastward as far as the Eubœan Sea. It was the scene of one of the most celebrated wars in the mythical annals of Greece. Polynices, who had been expelled from Thebes by his brother Eteocles, induced six other heroes to espouse his cause, and marched against the city; but they were all defeated and slain by the Thebans. This is usually called the war of the “Seven against Thebes.” A few years afterward, “the Epigoni,” or descendants of the seven heroes, marched against Thebes to revenge their fathers’ death; they took the city and razed it to the ground. It appears, however, at the earliest historical period as a large and flourishing city. The Thebans were from an early period inveterate enemies of their neighbors, the Athenians. Their hatred of the latter people was probably one of the reasons which induced them to desert the cause of Grecian liberty in the great struggle against the Persian power. In the Peloponnesian war the Thebans naturally espoused the Spartan side, and contributed not a little to the downfall of Athens; but they joined the confederacy formed against Sparta in 394 B.C. The peace of Antalcidas in 387 put an end to hostilities in Greece; but the treacherous seizure of the Cadmea by the Lacedæmonian general Phœbidas in 382, and its recovery by the Theban exiles in 379, led to a war between Thebes and Sparta, in which the former not only recovered its independence, but forever destroyed the Lacedæmonian supremacy. This was the most glorious period in the Theban annals; and the decisive defeat of the Spartans at the battle of Leuctra in 371 made Thebes the first power in Greece. Her greatness, however, was mainly due to the pre-eminent abilities of her citizens, Epaminondas and Pelopidas; and with the death of the former at the battle of Mantinea in 362, she lost the supremacy which she had so recently gained. The Thebans joined the Athenians in protecting the liberties of Greece; but their united forces were defeated by Philip of Macedon, at the battle of Chæronea, in 338. Soon after the death of Philip and the accession of Alexander, the Thebans made a last attempt to recover their liberty, but were cruelly punished by the young king. The city was taken by Alexander in 336, and was almost entirely destroyed; 6000 inhabitants were slain, and 30,000 sold as slaves. In 316 the city was rebuilt by Cassander, with the assistance of the Athenians. In 290 it was taken by Demetrius Poliorcetes, and again suffered greatly.
=Theodolite.= An instrument, variously constructed, used, especially in trigonometrical surveying, for the accurate measurement of horizontal angles, and also usually of vertical angles. The theodolite consists principally of a telescope, with cross-wires in its focus, mounted so as to turn both on vertical and horizontal axes, the former carrying a horizontal vernier-plate over a graduated plate or circle for aximuthal angles, and the latter a vertical, graduated arc or semicircle for altitudes,--the whole furnished with leveling-screws and levels for adjusting to the horizon, and mounted on a tripod. It is usually so constructed that a horizontal angle may be repeated indefinitely around the limb, and thus a large number of repetitions added mechanically, to secure greater accuracy in the resulting mean.
=Thermidor= (_i.e._, the “Hot Month”). Formed in the calendar of the first French republic the eleventh month, and lasted from July 19 to August 18. The 9th Thermidor of the Republican year 2 (July 27, 1794) is memorable as the date of Robespierre’s fall, and the termination of the “Reign of Terror.” The name of Thermidorians was given to all those who took part in this fortunate _coup d’état_, but more particularly to those who were desirous of restoring the monarchy.
=Thermopylæ= (literally, “the hot gates”). A famous pass leading from Thessaly into Locris, and the only road by which an invading army can penetrate from Northern into Southern Greece. Leonidas, at the head of 300 Spartans and 700 Thespians, at this pass withstood the whole force of the Persians during three days, August 7, 8, and 9, 480 B.C., when Ephialtes, a Trachinian, perfidiously leading the enemy by a secret path up the mountains, brought them to the rear of the Greeks, who, thus placed between two assailants, perished gloriously on heaps of their slaughtered foes. One Greek only returned home, and he was received with reproaches for having fled. Here also, Antiochus the Great, king of Syria, was defeated by the Romans, 191 B.C.
=Thermum=, =Thermus=, or =Therma=. A strong city, the acropolis of Ætolia, Northern Greece, was captured and ravaged by Philip V. of Macedon, 218 and 206 B.C., on account of its favoring the Romans.
=Thespiæ.= A city of Bœotia, Northern Greece; 700 of its citizens perished with Leonidas at Thermopylæ, August, 480 B.C. It suffered much through the jealousy of the Thebans, who destroyed its walls in 372 B.C.
=Thessalonica= (now _Saloniki_, more anciently _Therma_). An ancient city of Macedonia, situated at the northeast extremity of the Sinus Thermaicus. It was taken and occupied by the Athenians a short time before the commencement of the Peloponnesian war (432 B.C.), but was soon afterward restored by them to Perdiccas. At a later time, it became the capital of the Illyrian provinces. It is celebrated at this period on account of the fearful massacre of its inhabitants by order of Theodosius, in consequence of a riot in which some of the Roman officers had been assassinated by the populace.
=Thessaly.= The largest division of ancient Greece, lay to the south of Macedonia, and to the east of Epirus. Thessaly was originally inhabited by Æolians, who, however, were either expelled or reduced to slavery by immigrants from Epirus about 1000 B.C. The inhabitants of Thessaly have been divided into three classes: (1) There were the Epirote conquerors; (2) those descendants of the original inhabitants, who, although dependent on the nobles, yet possessed a few privileges; and (3) the Penestæ, or those of the original inhabitants who had been reduced to serfdom. Thessaly never played an important part in Grecian history; it was only after the Peloponnesian war it exercised any influence on the affairs of Greece. The Penestæ frequently rebelled against their masters, who were very frequently at war among themselves. Jason caused himself to be elected Tagus of all Thessaly about 374 B.C.; was assassinated in 370 B.C. The rule of Jason’s successors became so unbearable that, in 353 B.C., the old families called in the aid of Philip of Macedon, who, in 344, subjected the country to Macedonia. In 197 B.C., it was restored to freedom under the protection of Rome.
=Thetford.= A town of England, in Norfolk, 95 miles north-northeast of London. It was taken and sacked by the Danes in 870.
=Thin, To.= To make less numerous; as, to thin the ranks by a heavy discharge of musketry.
=Thionville.= A fortified town of France, in the department of the Moselle, situated on the Moselle, which is crossed here by a splendid bridge. This place was a residence of the Merovingian and Carlovingian kings, and was repeatedly besieged during the various wars between Austria and France. It was invested by the Germans in August, 1870, and after bombardment, being in flames, surrendered November 24 following.
=Thirty, Battle of= (Fr. _Combat des Trentes_). A name given, in English and French history, to a celebrated engagement which took place at a spot known as Midway Oak, half-way between the castles of Josselin and Ploermel, France, March 27, 1351. The French general Beaumanoir, commanding the former post, being enraged at the depredations committed by Bemborough, the English general, challenged him to fight. Upon this it was agreed that thirty knights of each party should meet and decide the contest. The two chiefs presented themselves at the head of their best soldiers and the battle began in earnest. At the first onset the English were successful; but Bemborough having been killed, the French renewed the struggle with redoubled courage and finally won the victory. This was one of the most heroic exploits of the age, and gained such popularity that more than one hundred years later, when speaking of a hard contest, it was usual to say, “There never was such hard fighting since the battle of the Thirty.”
=Thirty Tyrants.= A body of thirty magistrates in Athens (404-403 B.C.). They were appointed from the aristocratic party, by the Spartans, victorious in the Peloponnesian war. The “tyrants” were guilty of the most cruel and shameless acts, and after one year were expelled by Thrasybulus.
=Thirty Tyrants of Rome.= A set of military adventurers who from 253 to 268 attempted to establish their own power in various parts of the empire during the reigns of Valerianus and Gallienus. The number thirty is borrowed from that of the famous Athenian tyrants. The names of only nineteen of these adventurers have come down to us.
