 He then worked his way forward and, advancing directly into the enemy fire, killed 8 Japanese in spider holes guarding the approach to the pillbox.Crawling to within a few feet of the pillbox while his men concentrated their bullets on the fire port, he began dropping grenades through the narrow firing slit.The enemy immediately threw 2 or 3 of these unexploded grenades out, and fragments from one wounded him in the hand and back.
