On the afternoon of 28 February 1939 King and Halsey went together on board Houston where some twenty or more flag officers of the United States Flee… - Ernest King

The defensive organization of Iwo Jima was the most complete and effective yet encountered. The beaches were flanked by high terrain favorable to the defenders. Artillery, mortars, and rocket launchers were well concealed, yet could register on both beaches- in fact, on any point on the island. Observation was possible, both from Mount Suribachi at the south end and from a number of commanding hills and steep defiles sloping to the sea from all sides of the central Motoyama tableland afforded excellent natural cover and concealment, and lent themselves readily to the construction of subterranean positions to which the Japanese are addicted. Knowing the superiority of the firepower which would be brought against them by air, sea, and land, they had gone underground most effectively, while remaining ready to man their positions with mortars, machine guns, and other portable weapons the instant our troops started to attack. The defenders were dedicated to expending themselves- but expending themselves skillfully and protractedly in order to exact the uttermost toll from the attackers. Small wonder then that every step had to be won slowly by men inching forward with hand weapons, and at heavy costs. There was no other way of doing it. The skill and gallantry of our Marines in this exceptionally difficult enterprise was worthy of their best traditions and deserving of the highest commendation. This was equally true of the naval units acting in their support, especially those engaged at the hazardous beaches. American history offers no finer example of courage, ardor and efficiency.

Any man facing a major decision acts, consciously or otherwise, upon the training and beliefs of a lifetime. This is no less true of a military commander than of a surgeon who, while operating, suddenly encounters an unsuspected complication. In both instances, the men must act immediately, with little time for reflection, and if they are successful in dealing with the unexpected it is upon the basis of past experience and training. As any decisions that I made during World War II sprang from the forty-four years' service that were behind me in 1941, I wish to acquaint the reader with the background of my professional life so that he may better understand their origins.

Do the best you can with what you have. Do not worry about water that has gone over the dam. Difficulties exist to be overcome.
