Justinian now had his pretext, and with peace restored on his eastern frontier with Sassanid Persia in 532, he started assembling an invasion force. According to Procopius ("The Vandalic War", I.10), the news of Justinian's decision to go to war with the Vandals caused great consternation among the capital's elites, in whose minds the disaster of 468 was still fresh. The financial officials resented the expenditure involved, while the military was weary from the Persian war and feared the Vandals' sea-power. The emperor's scheme received support mostly from the Church, reinforced by the arrival of victims of renewed persecutions from Africa. Only the powerful minister John the Cappadocian dared to openly voice his opposition to the expedition, however, and Justinian disregarded it and pressed on with his preparations.
