Preparations on Either Side
The results of the first campaign in favour of Sulla were the submission of Apulia, Picenum, and Campania, the dissolution of the one, and the vanquishing and blockading of the other, consular army. The Italian communities, compelled severally to choose between their twofold oppressors, already in numerous instances entered into negotiations with him, and caused the political rights, which had been won from the opposition party, to be guaranteed to them by formal separate treaties on the part of the general of the oligarchy. Sulla cherished the distinct expectation, and intentionally made boast of it, that he would overthrow the revolutionary government in the next campaign and again march into Rome.
But despair seemed to furnish the revolution with fresh energies. The consulship was committed to two of its most decided leaders, to Carbo for the third time and to Gaius Marius the younger; the circumstance that the latter, who was just twenty years of age, could not legally be invested with the consulship, was as little heeded as any other point of the constitution. Quintus Sertorius, who in this and other matters proved an inconvenient critic, was ordered to proceed to Etruria with a view to procure new levies, and thence to his province Hither Spain.
