Tadamichi Kuribayashi Quote

We are sorry indeed we could not have defended the island successfully.

However, I comfort myself a little, seeing my officers and men die without regret after struggling in this inch-by-inch battle against an overwhelming enemy with many tanks and being exposed to indescribable bombardments. … I would like now to apologize to my senior and fellow officers for not being strong enough to stop the enemy invasion.
