Only people in the front lost units. That's what you get for not following the line settings!
Anyway, it was a very quick battle. It was so quick Toren's fort didn't take much damage 
People need to learn to listen to orders. Leaders giving out orders more than 1 time but still got people forget to follow, change accordingly. Sometimes this can cause a few surprises in battles especially closely fought ones.
One could argue that was a strategic mistake by Sandalak, handing a future enemy lvl 5 walls that need little maintenance.
What to do? Deal is a deal, if you catch my drift.
