I needed God's grace the morning of May 6, 1968. Mortar and sniper fire came raining down on us in the A Shau Valley, Vietnam. I threw my food in the air, grabbed my weapon, and ran to a bunker. I stood in the doorway. I did not want the enemy to sneak up and frag me. One mortar was over, second mortar short, the third mortar, I started stepping back.
