American Military History, Volume 1 by Richard W. Stewart

After the Spanish-American War the Army also underwent important organizational and administrative changes aimed in part at overcoming some of the more glaring defects revealed during the war. Although the nation had won the war with comparative ease, many Americans realized that the victory was attributable more to the incompetence of the enemy than to any special qualities displayed by the Army. In fact, as a postwar investigating commission appointed by President William McKinley and headed by Maj. Gen. Granville M. Dodge brought out, there was serious need for reform in the administration and direction of the Army's high command and for elimination of widespread inefficiency in the operations of the War Department.

No one appreciated the need for reform more than Elihu Root, a New York lawyer whom McKinley appointed Secretary of War in 1899. The President had selected Root primarily because he seemed well qualified to solve the legal problems that would arise in the Army's administration of recently acquired overseas possessions. But Root quickly realized that if the Army was to be capable of carrying out its new responsibilities as an important part of the defense establishment of a world power, it had to undergo fundamental changes in organization, administration, and training. Root, as a former corporation lawyer, tended to see the Army's problems as similar to those faced by business executives. "The men who have combined various corporations … in what we call trusts," he told Congress, "have reduced the cost of production and have increased their efficiency by doing the very same thing we propose you shall do now, and it does seem a pity that the Government of the United States should be the only great industrial establishment that cannot profit by the lessons which the world of industry and of commerce has learned to such good effect."
