To secure Greece, where all the states except the Acarnanians and Boeotians were now in arms against him, the garrison of Corinth was augmented to 6000 men, while he himself, straining the last energies of exhausted Macedonia and enrolling children and old men in the ranks of the phalanx, brought into the field an army of about 26,000 men, of whom 16,000 were Macedonian -phalangitae-.
