The Red Badge of Courage- Ch 19

In this Chapter Henry's regimen is fighting. They begin to run but then Wilson fires a shot. Henry then realizes that if they stay they will all die. Henry and Wilson then leave together and see a American flag on the ground. They pick it up while they are running and then they just dissappear. This part was really confusing and i don't understand where they went.

• I liked how exciting this chapter was but I couldn't understand the end and it really bothers me. Wilson and Henry are like fighting buddies now and they do everything together.
• Where did they go at the end of the chapter?
