Hays' Marines had been attacking this complex ever since their landing on the morning of D+1. In those 48 hours, 1/8 fired 54,450 rounds of .30-caliber rifle ammunition. But the real damage was done by the special weapons of the engineers and the direct fire of the halftracks. Capture of the largest position, a concrete pillbox near the beach, enabled easier approaches to the remaining bunkers. By 13:00, it was all over. At the Red 1/Red 2 pocket there was no accurate count of Japanese dead.
