My Dear Brother

Dear Oswald,
 
I ask that you not share this part of the letter with Mother, as I know it will devastate her. I feel it necessary to tell you that I have killed a man in the line of duty. Though I won’t share specific details, the circumstances led me to using the rifle training we received from Father to defend my crewmates. Please understand that I am not proud of what I did, but I do feel that it was the right choice at the time. I don’t blame you if you feel disappointed in me. I’m quite disappointed in myself, and the guilt I feel is heavy on my heart.
 
I will see you soon,
 
Isaac
