The military affairs of the Romans on the eve of the great relocation of the peoples

Since the second half of the III century, the border of the Roman state was subjected to such a monstrous pressure that it never knew before. Alamannes, Franks and Saxons constantly attacked the Gallic provinces, the Carmatians and Goths devastated the Dunay regions, and in the east the Persians turned entire cities to the ruins. These tribal unions and peoples were much more numerous and in military affairs much more skillful than those with whom the Romans dealt in the first half of the 3rd century. In addition, the new opponents of the empire were much more aggressive than the previous ones. The Germans were no longer limited to predatory raids and crossed the Rhine to settle in the Roman lands, and the Persians demanded to give them all the territories that once became part of the Achaemenid power. Being in a permanent war, the Roman Empire was like a besieged fortress. Besieged, but impregnable. What was the secret of Rome"s military successes? Where did his army scoop its strength in order not only to reflect the onslaught of enemies, but also to go into a large -scale offensive?
