going after cacciato

in my book, it starts out talking about everyone that died in, and the soldiers that were left were standing among all the dead bodies. the weather isn't very good since it is raining everyday, so everything is extremely muddy and their man holes are full of water. then it goes into talking about Cacciato, a soldier, who ran away to france. the soldiers that were in his group decide they half to go after him to catch him. so they start on their journey after him. they split up and tried to trap him in the middle, but Cacciato exscaped the trap and kept on moving forward. they no longer were on his trail, and had to make their own trail. meanwhile the sergeant was sick and not looking very good. half of the soldiers wanted to go back, and the others thought they should go after him, so they kept chugging away after him. then it goes into talking about one of the soldiers named Paul Berlin, and the troups he had under his command.
Responce-
so far in this book, i dont quite understand what is going on. i understand they are chasing after Cacciato, but have no clue why. you think if a soldier was running away, you wouldn't have a group chase after him, because then you are just taking more away from battle. i would think they would just shoot him in the leg if they had a chance, which they did while they were chasing after him. anyways they also have a sick sergeant, which they should be getting help form somewhere. what i like about this book is that is goes into a lot of detail, about the war and almost lets you experience whats going on. it makes the book more interesting and i think the reason he hasn't told us why cacciato is so special is because it keeps us interested and wondering why. it also makes you want to keep reading to figure out why they are chasing him, because it almost makes you mad that you you don't no. well thats all i have for today bye. :)
