Iwo: Assault on Hell gives a worms eye view of the fighting of perhaps WWII's bloodiest battle. Focusing mainly on Marines from the 27th Regiment (but also the 26th, ) 5th Marine Division, Iwo; Assault on Hell gives a glimpse of the violence and ferocity of what would become known as the "Gettysburg of the Pacific." Written from the interviews of over 100 Marines of the 5th Division, Iwo; Assault on Hell shows what the Marines faced from the moment they landed until they left- some on D-day, others days or weeks later, a rare few after 36 days, when the shattered remains of the 5th Marine Division left Iwo Jima.
