Ostrogoths Abandon Siege of Rome: Vitiges Retreats to Ravenna

Belisarius held Rome with just 5,000 men against an Ostrogothic army of 150,000. For over a year, Vitiges surrounded the city, cutting aqueducts and starving the population, yet the Byzantine general turned every assault into a masterclass in defensive warfare—sallies at dawn, ambushes in the suburbs, holding seven gates with rotating cavalry units. When Vitiges finally retreated to Ravenna in March 538, he'd lost tens of thousands of soldiers to a force thirty times smaller. The victory didn't just save Rome for Byzantium. It convinced Justinian that Italy could be reconquered, triggering two more decades of war that would devastate the peninsula so thoroughly that it wouldn't recover its population levels for 500 years. Sometimes winning costs more than losing.
