[Illustration: GREEK SOLDIERS IN ARMS From a Greek vase of about the time of the battle of Marathon] HOW THE ATHENIANS WERE ARMED. Although the Persians had six times as many soldiers as the Athenians, they were not so well armed for hand to hand fighting. Their principal weapon was the bow and arrow, while the Greeks used the lance and a short sword. The Greek soldier was protected by his bronze helmet, solid across the forehead and over the nose; by his breastplate, a leathern or linen tunic covered with small metal scales, with flaps hanging below his hips; and by greaves or pieces of metal in front of his knees and shins. He was also protected by a shield, often long enough to reach from his face to his knees. According to a strange custom the Athenians were led by ten generals, each commanding one day in turn. THE BATTLE-GROUND. Marathon was a plain about two miles wide, lying between the mountains and the sea. From it two roads ran toward Athens, one along the shore where the hills almost reached the sea, the other up a narrow valley and over the mountains. The Athenians were encamped in this valley, where they could attack the Persians if they tried to follow the shore road. The Persians landed from their ships and filled the plain near the shore. They wanted to fight in the open plain because they had so many more soldiers than the Athenians and because they meant to use their horsemen. For some time the Athenians watched the Persians, not knowing what it was best to do. Half the generals did not wish to risk a battle, but Miltiades was eager to fight, for he feared that delay would lead timid citizens or traitors to yield to the Persians. He finally gained his wish, and on his day of command the battle was ordered. THE BATTLE. The Persians by this time had decided to sail around to the harbor of Athens and had taken their horsemen on board their ships. When they saw the Greeks coming they drew up their foot-soldiers in deep masses. The Athenians and their comrades--the Plataeans--soon began to move forward on the run. The Persians thought this madness, because the Greeks had no archers or horsemen. But the Greeks saw that if they moved forward slowly the Persians would have time to shoot arrows at them again and again.
