From the Greek tele- (far, distant, at a distance) and machia (battle). This can mean either a battle fought at a distance in the sense that combatants are at a distance from one another---e.g., siege weapons, archery, etc.---or in the sense that one is speaking of a battle that is at some distance from oneself, a foreign war, etc. E.g., Odysseus' son in The Odyssey, Telemachus, is named this because his father is away at war.
