As a consequence, Attila did not fight against the real Roman Empire, as Joaquín Izquierdo Creselles states in his Summary of General History (Volume I, page 156): “Invasions begin. The barbarians took advantage of this disorganization to invade the Empire. The army was not even close to what it had once been; nobody wanted to be a soldier. The infantry was being recruited from among the lowest classes and the cavalry was almost totally made up of Barbarians. In reality, towards the end of the III Century there was no Roman Army to speak of”.....“ Barbarian gangs appeared in the IV and V Century, wherefore, it is not worth saying that the barbarians defeated the Roman army since it no longer existed in the era of invasions and on the contrary, it was the Barbarians who made up the new army that substituted the real one, the old one of the Republic and of the Empire”.
“In the V Century entire nations were confederated, as were the Burgundians and the Visigoths. There was nothing but Barbarian armies, commanded by Barbarian chiefs and that, nevertheless, were called Roman and fought for Rome. But in fact, the Roman power did not exist and the last invasions had to end with the shadow of the authority that remained in the Eternal City”.
The Huns entered Europe crossing the Tanais in the year 375. They defeated and conquered the Alanos, the Ostrogoths and other tribes, who populated the margins of the Danube. In the year 450, Attila founded Buba at the shores of the Danube extending his domicile to the North of this river and the Black Sea, as well as to the West of the Caucasian, including areas having Slav and Gothic populations of and Teutonic origins. The South of the Danube was also a Hun province, from the Sau River to Novi, in Thrace.
Attila, having an army of 700,000 men crosses the Rhine and defeats the King of the Burgundians, who intended to detain his advance. He divides his forces into two armies: one advances on Tongress and Airras, the other one, under his command, towards the Moselle Valley. He destroys Besançon and other cities of the Bourgogne. He conquers the Eastern part of France and in the year 451, places Orleans under siege. The Roman General Aetius and his ally Theodoricus, King of the Visigoths, gather and organize an army that they called the Roman Legions. Regarding the King of the Visigoths, we should note that he was in the second period of great strategic victories. His process was the following first period of great strategic victories, 150-300 (lasted 150 years), great depression, 300-402 (101 years), second period of great strategic victories 401-507 (106 years) and disintegration, 507-713 (206 years). Its total duration was 563 years.
Upon the advance of Aetius and Theodoricus, Attila lifts the siege on Orleans and executed a retreat behind Marne, concentrates his forces on the plains of Châlons, where his extraordinary cavalry had advantages in its actions. Aetius commanded the right wing and Theodoricus the left one, Sangipan, King of the Alans being in the center. The attack is initiated by Attila charging over the right wing and being rejected by Aetius.
Simultaneously, Theodoricus attacked the right wing of the Huns, successfully destroying it, but it cost his life. Facing this situation, Attila decided to retreat towards an area that he had previously fortified. There he maintained his position, until he retreated towards Italy with the rest of his army. In his march he left desolation and death everywhere. He is said to have expressed: “Grass will never grow again under the hoofs of my horse”.
He destroyed Aquilea and many other cities of the North of Italy. Due to the eloquence and majesty of San Leone, he stopped at the doors of Rome. He demanded a tribute from the Emperor Valentino III and afterwards, returned to the jungles of the Danube.
Victory over Attila was due to the mathematical-historical phase of the Visigoths in their second aggressive process or second period of Great Strategic Victories. The historical phase of the Romans also contributed to it. The Roman Empire disappears substituted by four rival Constantine kingdoms and the wars between them (306-337). In the year 405, the remains of the Roman Empire fall under the domination of the Germanic Empires, that is, it had its phase of disintegration (161-305) and afterwards, of relative independence until the year 405, in which the Germanics dominate.
This means that the Romans did not develop their own second nucleus upon finishing the independence phase mentioned, that in this case corresponds to the last of this era of unification of six and one-half centuries, and then begins the era of great demographic fractionation of six and one-half centuries, for a total of 1,700 years of the mathematical-historical cycle. In this manner then, with the Romans a second and last nucleus of self unification did not take place, different from the case of China in which there was one which started in the year 1950.
