The movements by which bodies of troops are enabled to change position, order, or formation. The term embrace! such movements as changes of front, formations of line, column, Echelon, or square. While the pri mary principles of scientific warfare remain prac- tically the same, the modern developments of artillery and musketry fire have greatly affected the dispositions of battlefields, ami consequently changed the essential principles involved in preparations for war. The ability of infantry, for instance, to wheel accurately, coolly, and with precision, or deploy in front of the enemy, with the steady deliberation of the parade ground, formerly so much admired, is today replaced completely by widely extended intervals in any line formation. Changes of front are now made speedily, the men moving by the shortest possible direction to their new front. In brief, the spirit of the old order of military evolution was to stamp out all individuality in the rank and file, making of the soldier an automaton of little or no value as a separate entity. Modern evolu- tions, on the other hand, magnify the individual, encourage individuality, and from time to time decrease the tactical unit of command. See Tactics, Military. EVORA, a'vo-ra. A city of Portugal, capital of the Province of Alemtejo, situated m • fertile and elevated plain, 75 miles east by south of Lis- bon (Map: Portugal, B 3). It is irregularly built, with narrow streets, and is protected by old walls and towers and some recently constructed fortifications. It contains remains of great his- toric interest. The Gothic cathedral dates from the twelfth century, and has considerable archi- tectural beauty. Of Roman antiquities there are a ruined temple of Diana with fine Corinthian columns and an old aqueduct (rebuilt) which supplies the city with water. Evora has been the seat of an archbishop since the sixteenth century, and has an archiepiscopal library with about 25.000 volumes and 2000 manuscripts, and a num- ber of paintings. The archaeological museum is one of the most interesting in Portugal. The town has cotton and woolen manufactures, and iron furnaces. It carries on a considerable trade in wine. Population, in 1890. 15,134: in 1900, 16,152. Evora, the ancient Ebora. was captured by the Romans in B.C. 80, and became a colony with the name Liberalitas Julia. It was taken by the Arabs in 712, but was recovered by the Christians in 1166. EVREUX, «*'vre'. The capital of the French Department of Lure.
