This watch point resists a simple story in which Roman military ability vanished at one decisive moment. The quoted passage says fourth- and early fifth-century armies retained the knowledge and potential to fight effectively and usually won when they deliberately accepted battle. Even the defeat at Adrianople in 378 is treated as serious without making it the army's death blow. Training, motivation, equipment, money, roads, bases, supply lines, and central political will determined whether surviving military knowledge could be translated into performance. Repeated civil wars then weakened emperors and finances while frontier defeats fed further internal conflict, producing a slow loss of state capacity rather than a single battlefield collapse.

Late Roman armies still had fighting power
The Belisarius excerpt argues that late Roman armies could still win battles, but political instability and decaying support systems made that performance harder to sustain.
