Answer: The Roman borders were being overrun by numerous tribes, and the devastation was immense.
Explanation:
St. Jerome spoke of how the Roman borders had being breached on many sides such as in Gaul and Germany by numerous tribes such as the Vandals, the Quadi, the Sarmati and the Alani.
He then mentions the devastation that these invasions had caused such as the thousands of people massacred in churches and how citizens have been captured and towns depopulated.
Germany quickly overran much of Europe and was victorious for more than two years by relying on a new military tactic called the "Blitzkrieg" (lightning war). Blitzkrieg tactics required the concentration of offensive weapons (such as tanks, planes, and artillery) along a narrow front.
