Fleeing combat

[Bestial Warlust]

I've been running a test game for my group to see how we take to TFT. This is our first time playing. One thing that came up last night was running away. For and engaged figure it seems nearly impossible to run away. I want to make sure I'm understanding this properly. Two combatants:

Rufus DX 11
Aticus DX 12


Rufus is taking a beating from Aticus so Rufus decides to flee. First turn Rufus wins the initiative roll he's engaged with Aticus so he decides to disengage. He can only move one hex away. Aticus now not engaged uses his movement turn to move toward Rufus (less then half his MA as Rufus could only move one hex) does the move and attack option.

The movement phase ends. Now Aticus has the higher DX so he attacks hits Rufus -- more damage Rufus is hurting bad again he can only move one hex with a disengage.

It seems that no matter what Rufus does he'll never get away as he is engaged the only option he has is to move one hex to get away and Aticus will always move up. Am I reading this correctly or is there something my pea brain is missing?
