Taking advantage of a five-year truce in the East, Belisarius was sent back to Italy with 200 ships in 544. He successfully reoccupied much of southern Italy, but, according to Procopius, he was starved of supplies and reinforcements by a jealous Justinian and so felt unable to march to Rome's relief. Procopius describes famine during the siege, in which the ordinary Romans, who were not rich enough to buy grain from the military, were reduced to eating bran, nettles, dogs, mice and finally "each other's dung". Pope Vigilius, who had fled to the safety of Syracuse, sent a flotilla of grain ships, but Totila's navy intercepted them near the mouth of the Tiber and captured them. A desperate attempt by Belisarius to relieve Rome came close to success but ultimately failed. After more than a year Totila finally entered Rome on 17 December 546, when his men scaled the walls at night and opened the Asinarian Gate. Procopius states that Totila was aided by some Isaurian troops from the imperial garrison who had arranged a secret pact with the Goths. Rome was plundered and Totila, who had expressed an intention to completely level the city, satisfied himself with tearing down about one third of the walls. He then left in pursuit of the Byzantine forces in Apulia.
