Correct answer.
You need to divide the peasants into 2 groups of one each.
Ignoring the obstacles (you can have more than 2 peasants), place one in each group and attack the ghosts.
The opponent will be forced to flee, as to surrender, they need to be a millionaire :)), otherwise, by attacking the peasants, the ghost army will go into the negative, and the next attack will destroy them.
