The novel is narrated by Xeones, a
perioikos and one of only three Greek survivors of the
Battle of Thermopylae. His story is dictated to
King Xerxes and transcribed by his court
historian, Gobartes. At
Thermopylae, the allied Greek nations deployed a small force of four thousand Greek heavy infantry against the invading
Persian army of two million strong. Leading the Greeks was a small force of three hundred
Spartans, chosen because they were all "sires" — men who had sons who could preserve their blood line, should they fall in battle. the Spartan Captain
Polynikes, a young Spartan warrior named Alexandros, and the Spartan officer
Dienekes. Pressfield employs detailed descriptions of the Spartan
phalanx in battle, as well as the superior training and discipline of the Spartan warriors. ==Reception==
