The Imperial army is continuing its retreat from the numerically superior Aldera forces at the base of the Alafatra mountain range.  They've set fire to the forest to buy themselves more time, but after a few days the fire is beginning to burn out.  To buy the time they need to finish the retreat, Ikta is forced to mountain a proactive mobile defense and keep the flames burning.  But the enemy general is breaking all the rules, and Ikta can't figure out his game.  By the time Ikta realizes what's happened, it's too late, and the enemy battering down his walls with a new weapon and sending their cavalry straight through the flames!
It's a lot faster than just 
having the infantry walk.
فهذا أسرع بكثير من جعل جندي المُشاة يسير على قدميه
Das geht schneller,
als die Infanterie marschieren zu lassen.
Así llegarán mucho más rápido
que haciendo caminar a la infantería.
Así llegarán más rápido
que haciendo caminar a la infantería.
Ils mettront donc moins de temps
pour venir jusqu’ici.
Decisamente più veloce 
che spostare la fanteria a piedi.
Assim é bem mais rápido do 
que fazer a infantaria andar.
Пешие они добирались бы дольше.
