There are 10 soldiers on the one side of the river. They need to go to the other side of the river. There is no bridge in the river and no one can swim in the river. One of the soldiers spots the boat with two boys inside. The boat is very small and the boys in the boats also very small. The boat can either hold two boys or one soldier.
