The Macronians then asked if the Hellenes would make a treaty with them, and give pledges to deal with them as with friends, and when the generals had agreed to this, they came through the water to the other side. The gods were called to witness, and as a pledge of friendship, the Macronians gave to the Hellenes a Barbarian spear, and received from them in return a Hellene spear. After this the Macronians set to work to help the Hellenes in cutting down trees to make a bridge, and re-crossed the river with their new friends. They also brought barley and other food for sale, and at parting supplied them with a guide to take them on to the next country, which was inhabited by the Colchians. In three days the Hellenes came to a chain of mountains already occupied by the Colchians, who were drawn up against them in battle array. The mountains were not too steep to be scaled, and the Hellenes halted and took counsel as to how they could best make the attack. It was at first proposed to advance in the form of a phalanx, that is to say in long lines, each close behind the next, but Xenophon thought there were many objections to this plan. ‘A phalanx,’ he said, ‘would be liable to fall out of line in climbing the mountain, for in some places we shall find the road good, and in other places bad. Moreover if the phalanx is at all deep, the lines will not extend far enough to outflank the enemy, and in that case they will be able to attack us at the wings or in the rear. And on the other hand, if we extend our lines far enough to obviate that danger, the phalanx will be shallow, and easily broken through. ‘My advice is that we divide the hoplites into separate companies of a hundred men each, and let them ascend in column, leaving spaces between the columns, so that they may extend beyond the enemy’s line. The bravest man in each company must head the column, and lead it up the mountain by the best path he can find. The Colchians will not venture to charge, for if they were to press in between the columns, they would be surrounded by enemies on both sides.’ This plan was agreed upon, and the hoplites were formed into eighty companies of a hundred men each, while the light-armed troops were divided into three detachments of about six hundred men each, and posted in the centre and at the two wings. Before advancing to the battle, Xenophon addressed the troops in a soldier-like speech, short, and to the point. ‘Comrades,’ he said, ‘these are the last enemies that stand in our path. Let us eat them up alive, if we can, without cooking.’
