Philip's continued encroachments. His insatiate ambition.

The peace between Philip and Athens lasted, without any formal renunciation, for six years, during which the Macedonian king pursued his aggressive policy and his intrigues in all the States of Greece. His policy was precisely that of Rome when it meditated the conquest of the world, only his schemes were confined chiefly to Greece. Every year his power increased, while the States of Greece remained inactive and uncombined—a proof of the degeneracy of the times—certainly in regard to self-sacrifices to secure their independence. Demosthenes plainly saw the approaching absorption of Greece in the Macedonian dominion, unless the States should unite for common defense; and he took every occasion [pg 367] to denounce Philip, not only in Athens, but to the envoys of the different States. The counsels of the orator were a bitter annoyance to the despot, who sent to Athens letters of remonstrance.

Athens at last aroused by Demosthenes. Siege of Perinthus. Philip withdraws from Byzantium.

At last an occasion was presented for hostilities by the refusal of the Athenians to allow Philip to take possession of the island of Halicarnassus, claiming the island as their own. Reprisals took place, and Philip demanded the possession of the Hellespont and Bosphorus, and the Greek cities on their coast, of the greatest value to Athens, since she relied upon the possession of the straits for the unobstructed importation of corn. The Athenians now began to realize the encroaching ambition of Philip, and to listen to Demosthenes, who, about this time, B.C. 341, delivered his third Philippic. From this time to the battle of Chæronea, the influence of Demosthenes was greater than that of any other man in Athens, which too late listened to his warning voice. Through his influence, Eubœa was detached from Philip, and also Byzantium, and they were brought into alliance with Athens. Philip was so much chagrined that he laid siege to Perinthus, and marched through the Chersonese, which was part of the Athenian territory, upon which Athens declared war. Philip, on his side, issued a manifesto declaring his wrongs, as is usual with conquerors, and announced his intention of revenge. The Athenians fitted out a fleet and sent it under Chares to the Hellespont. Philip prosecuted, on his part, the siege of Perinthus, on the Propontis, with an army of thirty thousand men, with a great number of military engines. One of his movable towers was one hundred and twenty feet high, so that he was able to drive away the defenders of the walls by missiles. He succeeded in driving the citizens of this strong town into the city, and it would have shared the fate of Olynthus, had it not been relieved by the Byzantine and Grecian mercenaries. Philip was baffled, after a siege of three months, and turned his [pg 368] forces against Byzantium, but this town was also relieved by the Athenians, and the inhabitants from the islands of the Ægean. These operations lasted six mouths, and were the greatest adverses which Philip had as yet met with. A vote of thanks was decreed by the Athenians to Demosthenes, who had stimulated these enterprises. Philip was obliged to withdraw from Byzantium, and retreated to attack the Scythians. An important reform in the administration of the marine was effected by Demosthenes, although opposed by the rich citizens and by Æschines.

Another sacred war. Ruinous to Grecian liberties.

While these events transpired, a new sacred war was declared by the Amphictyonic Council against the Locrians of Amphissa, kindled by Æschines, which more than compensated Philip for his repulse at Byzantium, bringing advantage to him and ruin to Grecian liberty. But the Athenians stood aloof from this suicidal war, when all the energies of Greece were demanded to put down the encroachments of Philip. As was usual in these intestine troubles, the weaker party invoked the aid of a foreign power, and the Amphictyonic Assembly, intent on punishing Amphissa, sought assistance from Philip. He, of course, accepted the invitation, and marched south through Thermopylæ, proclaiming his intention to avenge the Delphian god. In his march he took Nicæa from the Thebans, and entered Phocis, and converted Elatea into a permanent garrison. Hitherto he had only proclaimed himself as a general acting under the Amphictyonic vote to avenge the Delphian god,—now he constructed a military post in the heart of Greece.

Alliance of Thebes and Athens. Renewed military preparations of Philip.

Thebes, ever since the battle of Leuctra, had been opposed to Athens, and even now unfriendly relations existed between the two cities, and Philip hoped that Thebes would act in concert with him against Athens. But this last outrage of Philip exceedingly alarmed Athens, and Demosthenes stood up in the Assembly to propose an embassy to Thebes with offers of alliance. His advice was adopted, and he was dispatched with other envoys to [pg 369] Thebes. The Athenian orator, in spite of the influence of the Macedonian envoys, carried his point with the Theban Assembly, and an alliance was formed between Thebes and Athens. The Athenian army marched at once to Thebes, and vigorous measures were made at Athens for the defensive war which so seriously threatened the loss of Grecian liberty. The alliance was a great disappointment to Philip, who remained at Phocis, and sent envoys to Sparta, inviting the Peloponnesians to join him against Amphissa. But the Thebans and Athenians maintained their ground against him, and even gained some advantages. Among other things, they reconstituted the Phocian towns. The Athenians and their allies had a force of fifteen thousand infantry and two thousand cavalry, and Demosthenes was the war minister by whom these forces were collected. These efforts on the part of Thebes and Athens led to renewed preparations on the part of Philip. He defeated a large body of mercenaries, and took Amphissa. Unfortunately, the Athenians had no general able to cope with him, and it was the work of Demosthenes merely to keep up the courage of his countrymen and incite them to effort.

Battle of Chæronea. Its decisive character. Macedonian phalanx.

At last, in the month of August, Philip, with thirty thousand foot and two thousand horse, met the allied Greeks at Chæronea, the last Bœotian town on the frontiers of Phocis. The command of the armies of the allies was shared between the Thebans and Athenians, but their movements were determined by a council of civilians and generals, of which Demosthenes was the leading spirit. Philip, in this battle, which decided the fortunes of Greece, commanded the right wing, opposed to the Athenians, and his son Alexander, the left wing, opposed to the Thebans. The Macedonian phalanx, organized by Philip, was sixteen deep, with veteran soldiers in the front. The Theban “Sacred Band” was overpowered and broken by its tremendous force, much increased by the long pikes which projected in front of the foremost [pg 370] soldiers. But the battle was not gained by the phalanx alone. The organization of the Macedonian army was perfect, with many other sorts of troops, bodyguards, light hoplites, light cavalry, bowmen, and slingers. One thousand Athenians were slain, and two thousand more were made captives. The Theban loss was still greater.
