How is the battle front introduced in the story in the chapter The Dog of Tithwal?

The story takes place in a beautiful and peaceful country setting. The sweet smell of the blooming wildflowers is wafting in the soft breeze. The birds are heard chirping overhead, and the treed mountains rise beyond the field. It is the end of September, and the sky is a calm blue. The weather is just right. However, on either side of this beautiful field are two enemy trenches, in which soldiers have been living for several weeks. The two groups randomly exchange fire with no consequence either way. There are no casualties, attempted attacks or starving, shivering soldiers. These two battalions take on a civility that is not often seen in war.

The atmosphere is so civil, in fact, that the soldiers have grown bored of the war, since there is hardly any real action. There is no venting of their motive for war. Each side is evenly matched, with no clear advantage, and thus an end is nowhere in sight.
