Hideyoshi

Hi,

Does anyone have any advice on how to win the second battle of Hiyeshoshi's historical campaign where there are two groups of Battlefield Ninjas?

While we're at it, I couldn't get past Hideyohi's last mission. I could fight the enemy to a standstill but I always lost more than 25% within moments of the beginning, there's no time to set up; also, the opposing force is roughly equal to yours...

what to do.
