What does Dahl mean when he tells the Germans that they are now prisoners of war?

When Dahl tells the Germans that they are now prisoners of war, he is referring to their inability to move their convoy and the necessity for them to return. This statement signifies a complete shift in power dynamics, where the Germans who were once in control are now subject to the authority of the captors. By indicating that they cannot move, Dahl emphasizes their confinement and the reality of their situation as prisoners. This context captures the tension of wartime and illustrates the consequences of conflict, as well as the abrupt change from being combatants to captives.

The other options do not accurately reflect the meaning behind Dahl's declaration. They suggest either freedom or safety, which contradicts the idea of captivity and the loss of autonomy that comes with being a prisoner of war.
