Note 672 — Chapter XCV · GRECIAN AFFAIRS FROM THE LANDING OF ALEXANDER IN ASIA TO THE CLOSE OF THE LAMIAN WAR.
Reading edition
Alexander, as soon as he got possession of the Persian treasures at Susa (about December 331 B. C.), sent a large remittance of 3000 talents to Antipater, as means for carrying on the war against the Lacedæmonians (Arrian, iii. 16. 17). The manifestations of Agis in Peloponnesus had begun in the spring of 331 B. C. (Arrian, iii. 6, 4); but his aggressive movements in Peloponnesus did not assume formidable proportions until the spring of 330 B. C. At the date of the speech of Æschines against Ktesiphon (August 330 B. C.), the decisive battle by which Antipater crushed the forces of Agis had only recently occurred; for the Lacedæmonian prisoners were only about to be sent to Alexander to learn their fate (Æsch. adv. Kt. p. 524). Curtius (vii. 1, 21) is certainly mistaken in saying that the contest was terminated before the battle of Arbela. Moreover, there were Lacedæmonian envoys, present with Darius until a few days before his death (July 330 B. C.), who afterwards fell into the hands of Alexander (Arrian iii. 24, 7); these men could hardly have known of the prostration of their country at home. I suppose the victory of Antipater to have taken place about June 330 B. C.—and the Peloponnesian armament of Agis to have been got together about three months before (March 330 B. C.).
Mr. Clinton (Fast. H. App. c. 4. p. 234) discusses the chronology of this event, but in a manner which I cannot think satisfactory. He seems inclined to put it some months earlier. I see no necessity for construing the dictum ascribed to Alexander (Plutarch, Agesilaus, 15) as proving close coincidence of time between the battle of Arbela and the final defeat of Agis.
