what does Henry fear about himself as he lies in his bunk? How does the tall soldier temporarily ease Henry's fear?

Henry is concerned that he will run when he finally faces a conflict. He wants to be a hero, but his fears nag at him, making him doubt his own courage and mettle as he lies in his tent. Jim is confident that they will fight because they are from good stock; however, there is no way to tell since they have not yet been under fire. Henry finally asks Jim if he would run from the battle. Jim speculates that he might, especially if a whole group began to run. "But if everybody was a-standing and a-fighting, why, I'd stand and fight," he adds. These words comfort Henry as the first chapter ends.
