Mobilizing and Preparing for War on the Home Front

Learning Objectives

  • Describe the steps taken by the United States to prepare for war
  • Describe how the war changed employment patterns in the United States

The impact of the war on the United States was nowhere near as devastating as it was in Europe and the Pacific, where the battles were waged, but it still profoundly changed everyday life for all Americans. On the positive side, the war effort finally and definitively ended the economic depression that had been plaguing the country since 1929. It also called upon Americans to unite behind the war effort and give of their money, their time, and their effort, as they sacrificed at home to assure success abroad. The upheaval caused by White men leaving for war meant that for many disenfranchised groups, such as women and African Americans, there were new opportunities for employment and wage earning. Still, fear and racism drove cracks in the nation’s unified facade.

Mobilizing a Nation

Although the United States had sought to avoid armed conflict, the country was not entirely unprepared for war. Production of armaments had increased since 1939, when, as a result of Congress’s authorization of the Cash and Carry policy, contracts for weapons had begun to trickle into American factories. War production increased further following the passage of Lend Lease in 1941. However, when the United States entered the war, the majority of American factories were still engaged in civilian production, and many doubted that American businesses would be sufficiently motivated to convert their factories to wartime production.

Wartime Production Profits

Just a few years earlier, Roosevelt had been frustrated and impatient with business leaders when they failed to fully support the New Deal, but enlisting industrialists in the nation’s crusade was necessary if the United States was to produce enough armaments to win the war. To encourage cooperation, the government agreed to assume all costs of development and production, and also guarantee a profit on the sale of what was produced. This arrangement resulted in 233 to 350 percent increases in profits over what the same businesses had been able to achieve from 1937 to 1940. In terms of dollars earned, corporate profits rose from $6.4 billion in 1940 to nearly $11 billion in 1944. As the country switched to wartime production, the top one hundred U.S. corporations received approximately 70 percent of government contracts; big business prospered.

Building an Army

In addition to gearing up industry to fight the war, the country also needed to build an army. A peacetime draft, the first in American history, had been established in September 1940, but the initial draftees were to serve for only one year, a length of time that was later extended. Furthermore, Congress had specified that no more than 900,000 men could receive military training at any one time. By December 1941, the United States had only one division completely ready to be deployed. (A division is roughly 15,000 soldiers.) Military planners estimated that it might take nine million men to secure victory. A massive draft program was required to expand the nation’s military forces. Over the course of the war, approximately fifty million men registered for the draft; ten million were subsequently inducted into the service.

The Draft

Almost eighteen million men served in World War II. Volunteers rushed to join the military after Pearl Harbor, but the majority—over ten million—were drafted into service. Volunteers could express their preference for assignment, and many preempted the draft by volunteering. Regardless, recruits judged I-A, “fit for service,” were moved into basic training, where soldiers were developed physically and trained in the basic use of weapons and military equipment. Soldiers were indoctrinated into the chain of command and introduced to military life. After basic, soldiers moved on to more specialized training. For example, combat infantrymen received additional weapons and tactical training, and radio operators learned transmission codes and the operation of field radios. Afterward, an individual’s experience varied depending on what service he entered and to what theater he was assigned.

America Enters the War

The American war began slowly. Britain had stood alone militarily in Europe, but American supplies had bolstered their resistance. Hitler unleashed his U-boat “wolf packs” into the Atlantic Ocean with orders to sink anything carrying aid to Britain, but Britain’s and the United States’ superior tactics and technology won them the Battle of the Atlantic. British code breakers cracked Germany’s radio codes and the surge of intelligence, dubbed Ultra, coupled with massive naval convoys escorted by destroyers armed with sonar and depth charges, gave the advantage to the Allies and by 1942, Hitler’s Kriegsmarine was losing ships faster than they could be built. In North Africa in 1942, the British victory at El Alamein began pushing the Germans back. In November, the first American combat troops entered the European war, landing in French Morocco and pushing the Germans east while the British pushed west.

Native Americans and African Americans in Wartime

Approximately 2.5 million African Americans registered for the draft, and 1 million of them subsequently served. Initially, African American soldiers, who served in segregated units, had been used as support troops and were not sent into combat. By the end of the war, however, the need for more frontline soldiers resulted in African American recruits serving in the infantry and flying planes. The Tuskegee Institute in Alabama instituted a civilian pilot training program for aspiring African American pilots. When the war began, the Department of War absorbed the program and adapted it to train combat pilots. First Lady Eleanor Roosevelt demonstrated both her commitment to African Americans and the war effort by visiting Tuskegee in 1941, shortly after the unit had been organized. To encourage the military to give the airmen a chance to serve in actual combat, she insisted on taking a ride in a plane flown by an African American pilot to demonstrate the Tuskegee Airmen’s skill. When the Tuskegee Airmen did get their opportunity to serve in combat, they did so with distinction.

In addition, forty-four thousand Native Americans served in all theaters of the war. In some of the Pacific campaigns, Native Americans made distinct and unique contributions to Allied victories. Navajo marines served in communications units, exchanging information over radios using codes based on their native language, which the Japanese were unable to comprehend or crack. They became known as code talkers and participated in the battles of Guadalcanal, Iwo Jima, Peleliu, and Tarawa. A smaller number of Comanche code talkers performed a similar function in the European theater.

The story of ira hayes

Native Americans played an essential role during the American war efforts, and not just as code talkers. On February 25, 1945, during the Battle of Iwo Jima, six Marines raised an American flag at the summit of Mt. Suribachi, a territory deemed important to the United States’ island hopping campaign. In Joe Rosenthal’s iconic photograph above, one of the Marines depicted was a Native American member of the Pima tribe named Ira Hayes, one of 44,000 Indigenous persons who served in World War II.

Despite his bravery and an honorable discharge, like many returning veterans, Hayes struggled with PTSD upon his return home. Hayes succumbed to alcoholism as a coping mechanism, ultimately dying at the age of 32.[1] He and his fellow servicemen provided the basis for Arlington Cemetery’s Marine Corps War Memorial, constructed in 1954 as a three-dimensional representation of Rosenthal’s photograph.

Conscientious Objectors

While millions of Americans heeded the rallying cry for patriotism and service, there were those who, for various reasons, did not accept the call. Before the war began, American Peace Mobilization had campaigned against American involvement in the European conflict as had the noninterventionist America First organization. Both groups ended their opposition, however, at the time of the German invasion of the Soviet Union and the Japanese attack on Pearl Harbor, respectively. Nevertheless, during the war, some seventy-two thousand men registered as conscientious objectors (COs), and fifty-two thousand were granted that status. Of that fifty-two thousand, some accepted noncombat roles in the military, whereas others accepted unpaid work in civilian work camps. Many belonged to pacifist religious sects such as the Quakers or Mennonites. They were willing to serve their country, but they refused to kill. COs suffered public condemnation for disloyalty, and family members often turned against them. Strangers assaulted them. A portion of the town of Plymouth, NH, was destroyed by fire because the residents did not want to call upon the services of the COs trained as firemen at a nearby camp. Only a very small number of men evaded the draft completely.

Most Americans, however, were willing to serve, and they required a competent officer corps. The very same day that Germany invaded Poland in 1939, President Roosevelt promoted George C. Marshall, a veteran of World War I and an expert at training officers, from a one-star general to a four-star general, and gave him the responsibility of serving as Army Chief of Staff. The desire to create a command staff that could win the army’s confidence no doubt contributed to the rather meteoric rise of Dwight D. Eisenhower. During World War I, Eisenhower had been assigned to organize America’s new tank corps, and, although he never saw combat during the war, he demonstrated excellent organizational skills. When the United States entered World War II, Eisenhower was appointed commander of the General European Theater of Operations in June 1942.

General Eisenhower on Winning a War

Promoted to the level of one-star general just before the attack on Pearl Harbor, Dwight D. Eisenhower had never held an active command position above the level of a battalion and was not considered a potential commander of major military operations. However, after he was assigned to the General Staff in Washington, DC, he quickly rose through the ranks and, by late 1942, was appointed commander of the North African campaign.

Excerpts from General Eisenhower’s diary reveal his dedication to the war effort. He continued to work despite suffering a great personal loss.

March 9, 1942

General McNaughton (commanding Canadians in Britain) came to see me. He believes in attacking in Europe (thank God). He’s over here in an effort to speed up landing craft production and cargo ships. Has some d___ good ideas. Sent him to see Somervell and Admiral Land. How I hope he can do something on landing craft.

March 10, 1942

Father dies this morning. Nothing I can do but send a wire.
One thing that might help win this war is to get someone to shoot [Admiral] King. He’s the antithesis of cooperation, a deliberately rude person, which means he’s a mental bully. He became Commander in Chief of the fleet some time ago. Today he takes over, also Stark’s job as chief of naval operations. It’s a good thing to get rid of the double head in the navy, and of course Stark was just a nice old lady, but this fellow is going to cause a blow-up sooner or later, I’ll bet a cookie.

Gradually some of the people with whom I have to deal are coming to agree with me that there are just three “musts” for the Allies this year: hold open the line to England and support her as necessary, keep Russia in the war as an active participant; hold the India-Middle East buttress between Japs and Germans. All this assumes the safety from major attack of North America, Hawaii, and Caribbean area.

We lost eight cargo ships yesterday. That we must stop, because any effort we make depends upon sea communication.

March 11, 1942

I have felt terribly. I should like so much to be with my Mother these few days. But we’re at war. And war is not soft, it has no time to indulge even the deepest and most sacred emotions. I loved my Dad. I think my Mother the finest person I’ve ever known. She has been the inspiration for Dad’s life and a true helpmeet in every sense of the word.

I’m quitting work now, 7:30 p.m. I haven’t the heart to go on tonight.

—Dwight D. Eisenhower, The Eisenhower Diaries

What does Eisenhower identify as the most important steps to take to win the war?

Employment and Migration Patterns in the United States

Even before the official beginning of the war, the country started to prepare. In August 1940, Congress created the Defense Plant Corporation, which had built 344 plants in the West by 1945, and had funneled over $1.8 billion into the economies of western states. After Pearl Harbor, as American military strategists began to plan counterattacks and campaigns against the Axis powers, California became a training ground. Troops trained there for tank warfare and amphibious assaults as well as desert campaigns, since the first assault against the Axis powers was planned for North Africa.

As thousands of Americans swarmed to the West Coast to take jobs in defense plants and shipyards, cities like Richmond, California, and nearby Oakland, expanded quickly. Richmond grew from a city of 20,000 people to 100,000 in only three years. Almost overnight, the population of California skyrocketed. African Americans moved out of the rural South into northern or West Coast cities to provide the muscle and skill to build the machines of war. Building on earlier waves of African American migration after the Civil War and during World War I, the demographics of the nation changed with the growing urbanization of the African American population. Women also relocated to either follow their husbands to military bases or take jobs in the defense industry, as the total mobilization of the national economy began to tap into previously underemployed populations.

With the economy booming and twenty million American workers placed into military service, unemployment virtually disappeared. More and more African Americans continued to leave the agrarian South for the industrial North. And as more and more men joined the military, and more and more positions went unfilled, women joined the workforce en masse. Other American producers looked outside the United States, southward, to Mexico, to fill its labor force. Between 1942 and 1964, the United States contracted thousands of Mexican nationals to work in American agriculture and railroads in the Bracero Program. Jointly administered by the State Department, the Department of Labor, and the Department of Justice, the binational agreement secured five million contracts across twenty-four states.

Economic Changes and Rationing

Roosevelt and his administration already had experience in establishing government controls and taking the initiative in economic matters during the Depression. In April 1941, Roosevelt created the Office of Price Administration (OPA), and, once the United States entered the war, the OPA regulated prices and attempted to combat inflation. The OPA ultimately had the power to set ceiling prices for all goods, except agricultural commodities, and to ration a long list of items. During the war, major labor unions pledged not to strike in order to prevent disruptions in production; in return, the government encouraged businesses to recognize unions and promised to help workers bargain for better wages.

As in World War I, the government turned to bond drives to finance the war. Millions of Americans purchased more than $185 billion worth of war bonds. Children purchased Victory Stamps and exchanged full-stamp booklets for bonds. The federal government also instituted the current tax-withholding system to ensure the collection of taxes. Finally, the government once again urged Americans to plant victory gardens, using marketing campaigns and celebrities to promote the idea. Americans responded eagerly, planting gardens in their backyards and vacant lots.

Poster (a) reads “Your Victory Garden counts more than ever!” and features a series of bright vegetables in the foreground with a farm scene in the background. Poster (b) reads “Plant a Victory Garden. Our Food is Fighting. A Garden Will Make Your Rations Go Further.” An illustration of a man and a woman tending farm vegetables is shown, with a small boy in the foreground smiling at a large basket of freshly picked vegetables.

Figure 4. Wartime rationing meant that Americans had to do without many everyday items and learn to grow their own produce in order to allow the country’s food supply to go to the troops.

The federal government also instituted rationing to ensure that America’s fighting men were well fed. Civilians were issued ration booklets, books of coupons that enabled them to buy limited amounts of meat, coffee, butter, sugar, and other foods. Wartime cookbooks were produced, such as the Betty Crocker cookbook Your Share, telling housewives how to prepare tasty meals without scarce food items. Other items were rationed as well, including shoes, liquor, cigarettes, and gasoline. With a few exceptions, such as doctors, Americans were allowed to drive their automobiles only on certain days of the week. Most Americans complied with these regulations, but some illegally bought and sold rationed goods on the black market.

Civilians on the home front also recycled, conserved, and participated in scrap drives to collect items needed for the production of war materiel. Housewives saved cooking fats, needed to produce explosives. Children collected scrap metal, paper, rubber, silk, nylon, and old rags. Some children sacrificed beloved metal toys in order to “win the war.” Civilian volunteers, trained to recognize enemy aircraft, watched the skies along the coasts and on the borders.
