The Goettge patrol incident plus such Japanese tactics as playing dead and then throwing a grenade — or playing wounded, calling for a corpsman, and then knifing the medic when he came — plus the sneak attack on Pearl Harbor, caused the Marines to hate the Japanese intensely and to be reluctant to take prisoners.

The attitudes held toward the Japanese by noncombatants or even sailors or airmen often did not reflect the deep personal resentment felt by Marine infantrymen. Official histories and memoirs of Marine infantrymen written after the war rarely reflect that hatred. But at the time of battle, Marines felt it deeply, bitterly, and as certainly as danger itself. To deny this hatred or make light of it would be as much a lie as to deny or make light of the esprit de corps or the intense patriotism felt by the Marines with whom I served in the Pacific.

My experiences on Peleliu and Okinawa made me believe that the Japanese held mutual feelings for us. They were a fanatical enemy; that is to say, they believed in their cause with an intensity little understood by many postwar Americans — and possibly many Japanese, as well.

This collective attitude, Marine and Japanese, resulted in savage, ferocious fighting with no holds barred. This was not the dispassionate killing seen on other fronts or in other wars. This was a brutish, primitive hatred, as characteristic of the horror of war in the Pacific as the palm trees and the islands. To comprehend what the troops endured then and there, one must take into full account this aspect of the nature of the Marines’ war.
