which lines in this excerpt from Guy de Maupassant’s short story “Boule de Suif” suggest that the resistant activities of the civilians were more courage’s than those of the armed soldiers?

what is the context here? we need to know what story you're talking about : )

after the signature of the treaty of versailles in june 1919, germany lost nearly 25,000 square miles and a population of 7 million people. these territories included eupen-malmedy area and moresnet which were ceded to belgium. regarding relations with france, germany ceded the sovereignty of the saar coal mines to this country, as well as the provinces of alsace-lorraine.
