The Siege of Naples in 536 was a successful siege of Naples by the Byzantines under Belisarius during the Gothic War. The Byzantine army under Belisarius, having subdued Sicily with ease, landed on mainland Italy in late spring 536, and advanced along the coast on Naples. The citizens of Naples, roused by two orators, decided to resist. The siege dragged on for twenty days with numerous Byzantine casualties, and Belisarius was preparing to abandon it when his soldiers discovered an entrance into the city through the disused aqueduct. After giving the city a final chance to surrender, Belisarius launched his troops in a brutal sack. The Ostrogothic garrison of 800 men was taken prisoner and treated well, but the citizens suffered greatly at the hands of the Byzantine troops, and especially their Hunnic mercenaries. From Naples, the Byzantines marched on to Rome, which they entered in early December.
