"Stand, Stand, Shall They Cry" by Michael Ehart.
A wondrous tale of ancient Assyria.
"Yes, child, but not by choice. And look at how they are armed. I have only my sword. Against determined spearmen with secured flanks I would have no chance. They have positioned themselves well. On the bridge where they stand there is no way around them, and in the middle they are out of bow range, even if we still had our bows."
