Annoying bug and a glitch

In this chapter (BAPTISM OF FIRE) ther is a bug what ever i do it told me GAME OVER too many men died

What do you have the time to do? You need all the men you can bring… maybe you just dont have enough men.
When i done this quest i tell sir Radzik to bring all the men and ask for reinforcement from other lord.

I did ask for reinforcement

When they ask how many bandit i choose the highest number of bandit.
Also at some point if you have too many losses you just cant win.
When do you get the too many man died at the start of the combat or later?
