In the campaign of Philomelion Alexios led a sizeable Byzantine army deep into the Anatolian interior.
Anna Komnene, the primary source for the campaign, implies that the Seljuq capital of Iconium was the goal of the expedition, but evidently Alexios abandoned this plan and contented himself with staging a conspicuous show of force and evacuating the native Christian population from the Turkish dominated areas his army passed through. The Byzantines were to employ a new battle formation of Alexios' devising, the
parataxis. Anna Komnene's description of this formation is so imprecise as to be useless. However, from her account of the army in action the nature of the
parataxis is revealed; it was a defensive formation, a hollow square with the baggage in the centre, infantry on the outside and cavalry in-between, from whence they could mount attacks. An ideal formation for tackling the fluid Turkish battle tactics, reliant on swarm attacks by horse-archers. A similar formation was later employed by
Richard I of England at the
Battle of Arsuf. The Byzantines moved through Santabaris, sending detachments via
Polybotos and Kedros, and, after dispersing Turkish resistance, took Philomelion by assault. Parties of scouts were then sent out to round up the local Christian population for evacuation to areas under firm Byzantine control. ==Battle==
