At another uncertain date, Pliny was transferred back to Germania Inferior. Corbulo had moved on, assuming command in the east. This time, Pliny was promoted to "praefectus alae", "commander of a wing", responsible for a cavalry battalion of about 480 men. He spent the rest of his military service there. A decorative "phalera", or piece of harness, with his name on it has been found at "Castra Vetera", modern Xanten, then a large Roman army and naval base on the lower Rhine. Pliny's last commander there, apparently neither a man of letters nor a close friend of his, was Pompeius Paullinus, governor of Germania Inferior AD 55–58. Pliny relates that he personally knew Paulinus to have carried around 12,000 pounds of silver service on which to dine on campaign against the Germans (a practice which would not have endeared him to the disciplined Pliny).
