In part: “I wrote you V mail this morning…. I am sorry you have not been receiving my letters. I do not understand that because I have written you every day…. I hope you and the two little boys are all well…. I would give anything if I could see them. No one will ever know how my heart aches to see you…. I love you more than anything in all the world…. I live in hopes. So many times I have wished I could talk over things with you because they involve decisions…. Everything I do is done with you in mind….” So much for the tough-guy image.
