Next to the royal squadron on the right wing, half of the Agrianians, under the command of Attalus, in conjunction with the Macedonian archers under Briso's command, were posted angular-wise (i.e. in such a way that the wings were thrown forward at an angle with the centre, so as to take the enemy in flank) in case they should be seized anyhow by the necessity of folding back the phalanx or of closing it up (i.e. of deepening it by countermarching from front to rear).
