Unlike the other belligerents, the United States had made virtually no
military preparations for war on the scale that armed conflict developed
starting in 1914. The country not only lacked a large army, it also had no
plans for massive mobilization, and even the small army it had in hand—less
than 130,000 officers and men augmented by 180,000 in the National
Guard—was scattered and poorly trained. Only in the navy, comprised of
some 60,000 men and 300 ships, did the United States have a force capable
of rapid application.-
The need to man a large army and navy, and to do it quickly, convinced
a reluctant President Wilson to adopt conscription. In a major policy shift
from the traditional American reliance on voluntarism to fill the ranks.
Congress passed the Selective Service Act authorizing a universal conscription
policy to meet any manpower needs during war or a national emergency.
Through local draft boards, the government registered 24 million men
between the ages of eighteen and forty-five. Almost 3 million American
males found themselves called into military service. More than 1.5 million
more volunteered. For most of them, military service brought a new acquaintance
with distant parts of the country and fellow soldiers from other
groups in the population. In the 42nd (Rainbow) Division, for example,
troops from twenty-six states and the District of Columbia served together.
The army also was the venue for furthering Wilson's and the Progressives'
social reforms. The anti-venereal disease and anti-prostitution campaigns
the Progressives had launched in American cities now went to the army
camps. Soldiers were warned that "a German bullet is cleaner than a whore."
To the consternation of segregationist politicians from the South like
Senator James Vardaman of Mississippi, roughly 400,000 African Americans
served in the military. Although blacks were confined to segregated units and
often left to do fatigue duty such as hauling goods and trash removal, two
black divisions did reach the front. The 92nd Division fought as a unit under
American command. Its performance was roundly condemned by white
senior officers, although its problems stemmed in part from poor training and
inadequate leadership. Regiments of the 93rd Division, however, saw combat
as part of the French army and fought valiantly.
For over 2 million young Americans, conscription meant a personal
encounter with European life as well as the threat of death or injury in combat.
Processing young Americans for military service produced information on
the population that no one had possessed before. Some was highly disturbing:
doctors examining the recruits found that almost 30 percent were physically
unable to meet the standards for military service. During World War I social
scientists and medical doctors conducted the first mass testing of Americans
as to "intelligence." Using the recendy developed Binet intelligence test
—
which later scientists showed to have been skewed in favor of western
European cultures, among other defects—the testers "confirmed" many popular
stereotypes about the "inferiority" of blacks and southern and eastern
European groups. Armed with such "scientific" data, racists and nativists
called for restrictions on blacks and limits on immigration.
