I realized I couldn’t give them to a friend because all my friends were going on the mission with me, and we all might die. I had to go searching for someone I sort of knew, and trusted. I came up with a Navy intelligence guy. I gave him all these complicated instructions regarding who got which letter and where to find them. And, of course, I told him that if I lived I wanted those letters right back, because shredding them was the first thing I wanted to do.
