4. C. Didius
, a legate of C. Julius Caesar, who sent him, in B. C. 46, to Spain against Cn. Pompeius.
In the neighbourhood of Carteia he gained a naval victory over Q. Attius Varus, and in the year following he set out from Gades with a fleet in pursuit of Cn. Pompeius, who had taken to flight. Pompeius was compelled to land, and Didius took or burnt his ships. Didius himself likewise landed, and after Pompeius had been killed by Caesennius Lento, Didius was attacked by the Lusitanian soldiers of Pompeius, and fell under their strokes. (D. C. 43.14
