同学你好~
At the night, it was so dark.
地道的说法是It was pitch-dark at night. 注意night前不加the

A prisoner of war who had escaped was dressed as a guard up and down in front of the camp.
up and down前缺少动词，比如walking之类的。

Though they were running here and there to find him, nothing was found.
to look for him 寻找他，find是“找到”

They went into the countryside and paid a visit for all villagers to search the prisoner.
paid a visit for all villagers拜访所有村民就不是a visit了，可以改成called on all villagers 号召所有村民

effort用单数，did not get anything at all改成got nothing

祝同学学习进步~
