Plataea was a small place, probably not very strongly fortified, and contained a garrison of only four hundred and eighty men, of whom eighty were Athenians. Fortunately, all the women and children had been sent to Athens, the only women remaining in the town being about a hundred slaves, who served as cooks. Around this small place gathered the entire army of Sparta and her allies, a force against which it seemed as if the few defenders could not hold out a week. But these faithful few were brave and resolute, and for a year and more they defied every effort of their foes. The story of this siege is of interest as showing how the ancients assailed a fortified town. Defences which in our times would not stand a day, in those times took months and years to overcome. The army of Sparta, defied by the brave garrison, at first took steps to enclose the town. If the defenders would not let them in, they would not let the defenders out. They laid waste the cultivated land, cut down the fruit-trees, and used these to build a strong palisade around the entire city, with the determination that not a Plataean should escape. This done, they began to erect a great mound of wood, stones, and earth against the city wall, forming an inclined plane up which they proposed to rush and take the city by assault. The sides of this mound were enclosed by cross-beams of wood, so as to hold its materials in place. For seventy days and nights the whole army worked busily at this sloping mound, and at the end of this time it had reached nearly the height of the wall. But the Plataeans had not been idle while their foes were thus at work. They raised the height of their old wall at this point by an additional wall of wood, backed up by brickwork, which they tore down houses to obtain. In front of this they suspended hides, so as to prevent fire-bearing arrows from setting the wood on fire. Then they made a hole through the lower part of the town wall, and through it pulled the earth from the bottom of the mound, so that the top fell in. The besiegers now let down quantities of stiff clay rolled up in wattled reeds, which could not be thus pulled away. Yet their mound continued to sink, in spite of the new materials they heaped on top, and they could not tell why. In fact, the Plataeans had dug an underground passage from within the town, and through this carried away the foundations of the mound. And thus for more than two months the besiegers built and the garrison destroyed their works. Not content with this, the Plataeans built a new portion of wall within the town, joining the old wall on both sides of the mound, so that if the besiegers should complete their mound and rush up it in assault, they would find a new wall staring them in the face, and all their labor lost.
