The Crucifix Soldier was a man that Cassie Sullivan ran into when she stopped in a gas stop for supplies. She had run into him huddled in a corner and he seemed hurt. She had her gun on him and he put his gun away to help put her mind at ease. When she saw his other hand was concealed, she told him to take it out to see what he was holding. He slowly moved it but Cassie was too tense and thought he had a gun hidden. She let bullets loose on him and killed him. She then went to see what he had hidden and saw that he only had a crucifix.
This event followed Cassie throughout the book and she even wrote about it in her journal to try and quell her guilt. It haunted her for weeks on end.
Evan Walker learned about the Crucifix Soldier when he read Cassie's journal and brought it up to Cassie's shock and anger.
Cassie's mind went back to the Crucifix Soldier when she ran into a doctor at Camp Haven. He had reached into his pocket much like the soldier had his hand in his pocket. Cassie felt something different facing this doctor opposed to the soldier and pulled out her gun to see that the doctor did have an actual gun.
