10. SER. SULPICIUS GALBA, a grandson of No. 6, and great-grandfather of the emperor Galba. He was sent by Caesar at the beginning of his Gallic campaign, in B. C. 58, against the Nantuates, Veragri and Seduni, and defeated them; but he, nevertheless, led his army back into the country of the Allobrogians. In B. C. 54 he was praetor urbanus. In B. C. 49 he was a candidate for the consulship; but, to the annoyance of his friend J. Caesar, he was not elected. He was a friend of Decimus Brutus and Cicero; and in the war of Mutina, of which he himself gives an account in a letter to Cicero still extant (ad Fam. 10.30), he commanded the legio Martia. (Caes. Gal. 3.1, 6, 8.50; D. C. 37.48, 39.5, 65 ; Cic. Fam. 6.18, 11.18, Philip. 13.16; V. Max. 6.2.11.) According to Suetonius (Galba, 3; comp. Appian, App. BC 2.113), he was one of the conspirators against the life of J. Caesar.
