The officers and men of the Merchant Marine, by their devotion to duty in the face of enemy action, as well as natural dangers of the sea, have brought us the tools to finish the job. Their contribution to final victory will be long remembered.

--General Dwight D. Eisenhower on National Maritime Day, 1945¹

In the nearly 20 years following the end of the World War I, America's merchant fleet, including its cargo and passenger ships, was becoming obsolete and declining in numbers. A shipbuilding program began with the passage of the Merchant Marine Act of 1936. However, World War II provided the impetus to intensify those efforts eventually leading to a ship-building program that produced 5,500 vessels. Among them were 2,710 mass-produced ships known as Liberty ships. While reviewing blueprints of the Liberty ships at the White House, President Franklin D. Roosevelt, who loved naval vessels and had an eye for design, mused aloud to Maritime Commission administrator Admiral Emory S. Land, "I think this ship will do us very well. She'll carry a good load. She isn't much to look at, though, is she? A real ugly duckling."² Thus, the Liberty ships received their second nickname, "the ugly ducklings."


When the United States entered World War II at the end of 1941, it had the beginnings of a great merchant fleet. But the lethal U-Boats, submarines of the German Navy, prowled the shipping lanes hunting American merchant ships. The Liberty ships proved to be too slow and too small to carry the tons of supplies the United States and her Allies would need to win the war. In 1943, the United States began a new ship-building program. These new ships would be faster, larger, and able to carry cargo long after the war was finished. These were the Victory ships.

The Liberty and Victory ships fulfilled President Roosevelt's prophetic words, serving the nation well in war and peace. Today, of the thousands of Liberty ships and Victory ships built during World War II, only a handful remain.

Why do you think the U.S. Post Office issued this stamp?

Setting the Stage

In 1936, Congress passed the Merchant Marine Act, creating the U.S. Maritime Commission to oversee "... that the United States shall have a merchant marine…to provide shipping service essential for maintaining the flow of such domestic and foreign waterborne commerce at all times, capable of serving as a naval and military auxiliary in time of war or national emergency, owned and operated under the United States flag…, composed of the best-equipped, safest, and most suitable types of vessels…, and supplemented by efficient facilities for shipbuilding and ship repair."¹ The fleet of ships responsible for this mission is called the U.S. Merchant Marine.

At the time the act was passed, the majority of the ships in the merchant fleet were over 20 years old. The original plan was to build 50 ships per year for 10 years. However, World War II began in 1939, when Hitler's Germany invaded Poland. The United States realized that the existing construction program was not adequate to meet the changing world situation. During World War II the Merchant Marine was nationalized, that is, the U.S. government controlled the cargo and the destinations, contracted with private companies to operate the ships, and put guns and Navy personnel (Armed Guard) on board. The government trained civilian men to operate the ships and assist in manning the guns through the U.S. Maritime Service.

With Hitler's attack on Great Britain in 1940, the need for the United States to increase ship production became critical. The British could no longer produce ships in great numbers and also needed food and supplies. The United States knew that if Great Britain fell it would have no allies in Western Europe. Under the Lend-Lease program (which enabled the president to transfer arms and equipment to any nation deemed vital to the defense of the United States), the U.S. agreed to build commercial ships for Great Britain. American ship builders began to construct these ships using an old, but reliable, English design.

In 1939 the German Navy launched submarine warfare in the North Atlantic Ocean to enforce a naval blockade against Great Britain. Their submarines, called Unterseebooten or U-Boats, sank great numbers of merchant ships approaching the British Isles. Under these pressures, the United States greatly increased the production of its own merchant fleet. Cargo ships were needed to ferry supplies to allies if the United States entered the war. The United States decided to modify the English design being used for the Lend-Lease ships. The new emergency cargo ships came to be known as the Liberty ships. Yet, between 1939 and 1940, only 82 vessels were constructed. In 1941, Congress passed the Ship Warrants Act, giving the Maritime Commission power to allot ship construction priorities. Since existing shipyards were working full capacity on naval contracts, the Maritime Commission established 18 new shipyards to work on these identical merchant ships. They were built on a common design in assembly-line fashion along the West, East, and Gulf coasts of the United States. Parts were manufactured in every state in the country.

Following the Japanese attack on Pearl Harbor on December 7, 1941 and U.S. entry into World War II, ships were being sunk by German U-Boats almost as fast as they were being built. The Maritime Commission called for 2,000 ships to be constructed by the end of 1943. (The Japanese also inflicted a toll on supply ships in the Solomon Islands and New Guinea, but following their naval and air losses at Coral Sea and Midway, in mid-1942, they were less of a problem to merchant shipping than the Germans.) The ship building effort was a success. Finally, the United States had enough ships to keep pace with the losses caused by the U-Boats.

However, the Liberty ships were slow and small. Their design had a weakness in the hull that caused ships to sometimes break in two. In 1943, the United States started a new emergency cargo ship program to replace the Liberty ships. The newer ships were bigger and faster with better engines. These ships were designated Victory ships. While the Liberty ships were designed to be the workhorse of the war, Victory ships could continue to be used after the war as part of the regular merchant fleet.

The Liberty and Victory ships were adapted to suit the operational needs of each branch of the military service. Many carried cargo, while others were fitted out as troop carriers. Some were used as tankers carrying fuel for ships, vehicles and aircraft. Still others were fitted out as hospital ships or used to transport enemy prisoners of war. Ultimately, both the Liberty ships and Victory ships served with distinction in both the Atlantic and Pacific Oceans during World War II.

Determining the Facts

Reading 1: Liberty Ships

When war broke out Europe in September 1939, the merchant fleet was caught unprepared to handle a massive sealift of war material. With continental Europe under German control, and Great Britain under devastating air attack, President Franklin Roosevelt decided to increase the pace of production to provide ships to America's British allies. The result was the emergency fleet program, which introduced the assembly-line production of standardized ships--the Liberty ships--in 1941. The Liberty ship represented the design solution that would fill the need for an emergency type of simple, standardized cargo steamer. Based on a British design, it could be mass-produced cheaply and quickly using assembly-line methods and could easily be converted to individual military service needs. The United States designated this new type of ship the EC2 (E for emergency, C for cargo and 2 for a medium-sized ship between 400 and 450 feet at the waterline.) Production speed grew more important as German submarines sank ships trying to break Hitler's naval blockade of Great Britain. The Allies needed ships by the hundreds to replace these losses and to increase the flow of supplies to England and, later, the Soviet Union.

The first of these new ships was launched on September 27, 1941. It was named the SS Patrick Henry after the American Revolutionary War patriot who had famously declared, "Give me liberty, or give me death." Consequently, all the EC2 type of emergency cargo ships came to be known as Liberty ships. Naming nearly 3,000 ships turned out to be harder than people thought. Unlike the later Victory ships, there was no plan for how the Liberty ships would be named. In the end, the Liberties were named for people from all walks of life. Ships were named after patriots and heroes of the Revolutionary War. They were named after famous politicians (Abraham Lincoln to Simon Bolivar), scientists (George Washington Carver to Alexander Graham Bell), artists (Gilbert Stuart to Gutzon Borglum who sculpted Mt. Rushmore) and explorers (Daniel Boone to Robert E. Peary). One ship was named the SS Stage Door Canteen after the famous U.S.O. club for military service members while another was named the SS U.S.O. in honor of the United Service Organization itself.

The Liberty ships were slightly over 441 feet long and 57 feet wide. They used a 2,500 horsepower steam engine to push them through the water at 11 knots (approximately 12.5 miles per hour). The ships had a range of 17,000 miles. Liberty ships had five cargo holds, three forward of the engine room and two aft (in the rear portion of the ship). Each could carry 10,800 deadweight tons (the weight of cargo a ship can carry) or 4,380 net tons (the amount of space available for cargo and passengers). The crew quarters were located amidships (the middle portion of the ship).

Many technological advances were made during the Liberty shipbuilding program. A steel cold-rolling process was developed to save steel in the making of lightweight cargo booms. Welding techniques also advanced sufficiently to produce the first all-welded ships. Prefabrication was perfected, with complete deckhouses, double-bottom sections, stern-frame assemblies and bow units speeding production of the ships. By 1944, the average time to build a ship was 42 days. In all, 2,751 Liberties were built between 1941 and 1945, making them the largest class of ships built worldwide.

Each Liberty ship carried a crew of between 38 and 62 civilian merchant sailors, and 21 to 40 naval personnel to operate defensive guns and communications equipment. The Merchant Marine served in World War II as a Military Auxiliary. Of the nearly quarter million volunteer merchant mariners who served during World War II, over 9,000 died. Merchant sailors suffered a greater percentage of fatalities (3.9%) than any branch of the armed forces.

The Liberty ship was considered a "five-year vessel" (an expendable, if necessary, material of war) because it was not able to compete with non-emergency vessels in speed, equipment and general serviceability. However, Liberties ended up doing well, plodding the seas for nearly 20 years after the end of World War II. Many Liberties were placed in the reserve fleet and several supported the Korean War. Other Liberties were sold off to shipping companies, where they formed the backbone of postwar merchant fleets whose commerce generated income to build the new ships of the 1950s and 1960s. However, age took its toll and by the mid-1960s the Liberties became too expensive to operate and were sold for scrap, their metal recycled. The first Liberty built, the Patrick Henry, was sent to the ship breakers (scrap yard) in October 1958.

Of the nearly 3,000 Liberty ships built, 200 were lost during World War II to enemy action, weather and accidents. Only two are still operational today, the SS Jeremiah O'Brien and the SS John W. Brown.

Reading 2: Victory Ships

In 1943, the U.S. Maritime Commission embarked on a program to design new types of emergency fleet ships, most importantly fast cargo vessels, to replace the slower Liberty ships. The standardized design adopted by the Commission called for a ship 445 feet long by 63 feet wide and made of steel. On April 28, 1943, the new ships were given the name "Victory" and designated the VC2 type (V for Victory type, C for cargo, and 2 for a medium sized ship between 400 and 450 feet long at the waterline).

The Victory ships ultimately were slightly over 455 feet long and 62 feet wide. Like the Liberty ships, each had five cargo holds, three forward and two aft. The Victories could carry 10,850 deadweight tons (the weight of cargo a ship can carry) or 4,555 net tons (the amount of space available for cargo and passengers), a larger load than the Liberties could manage. Victory ships typically carried a crew of 62 civilian merchant sailors and 28 naval personnel to operate defensive guns and communications equipment. The crew quarters were located amidships. The Victory ships were different from the Liberty ships primarily in propulsion, the steam engine of the Liberty giving way to the more modern, faster steam turbine. The Victory ships had engines producing between 5,500 to 8,500 horsepower. Their cruising speed was 15-17 knots (approximately 18.5 miles per hour).

The ship profile and the construction techniques of the Victories were also different from the Liberties. One important feature of the Victory ship was in the internal design of the hull, the ship's framework. The Liberty ships had the frames inside the hull set 30 inches apart. This made the hull very rigid. This rigidity caused the hull to fracture in some of the ships. The Victory ships had their hull frames set 36 inches apart. Because the hull could flex, there was less danger of fracture.

The first Victory ship completed was the SS United Victory (built at Oregon Shipbuilding, Portland, OR), launched on January 12, 1944 and delivered February 28. The next 33 ships were named after member countries of the United Nations (e.g., SS Brazil Victory and SS U.S.S.R. Victory [both built by California Shipbuilding Corporation, Los Angeles, CA], and SS Haiti Victory [built by Permanente Metals Corporation, yard 1, Richmond, CA]). The ships that followed were named for cities and towns in the United States (e.g., SS Ames Victory [built by Oregon Shipbuilding], SS Las Vegas Victory [built by Permanente Metals Corporation, yard 1] and SS Zanesville Victory [built by Bethlehem-Fairfield Shipyards, Inc., Baltimore, MD]) and for American colleges and universities (e.g., SS Adelphi Victory and SS Yale Victory [both built by Permanente Metals Corporation, yard 2]). All of the ships' names ended with the suffix "Victory" with the exception of the 117 Victory Attack Transports that were named after state counties. The Maritime Commission built 414 Victory cargo ships and 117 Victory attack transports for a total of 531 vessels during the course of the war.

Victory ships formed a critical maritime link to the theaters of war. These fast, large capacity carriers served honorably in both the Atlantic and Pacific theaters of war. Ninety-seven of the Victories were fitted out as troop carriers; the others carried food, fuel, ammunition, material and supplies.

At the war's end a number of Victory ships were offered for sale by the Maritime Commission. One hundred and seventy were sold, 20 were loaned to the U.S. Army and the rest were stored as part of the reserve fleet. When the Navy no longer needs to use a ship but wishes to reserve it for a future emergency, it tows the ship to storage harbors, empties it of all fuel and cargo, and seals its windows and doors. The ship is protected from salt-water corrosion by a cathodic protection system and the interior spaces are dehumidified. This technique is called "mothballing," because it echoes how people preserve a wool sweater that is put away for the summer.

Some vessels were reactivated to serve during times of national crisis, including the Korean War, the Suez Canal closure of 1956 and the Vietnam War. Other vessels were retained as logistic support ships as part of the Military Sealift Command, which in 1970 became the single managing agency for the Department of Defense's ocean transportation needs. The command assumed responsibility for providing sealift and ocean transportation for all military services as well as for other government agencies. In 1959, eight Victory ships were reclassified and refitted as instrumentation, telemetry, and recovery ships for the National Aeronautics and Space Administration (NASA) in support of America's space program. On August 11, 1960, the former SS Haiti Victory (renamed the USNS Haiti Victory (T-AK-238)) recovered the nose cone of the satellite Discoverer XIII, the first man-made object recovered from space.

Over the years, many ships in the reserve fleet have been sold for scrap, their metal to be recycled. Of the thousands of Liberty ships and Victory ships produced only a small number remain.

Reading 3: Selected Ships' Histories

As the years went by, age took its toll on the Liberty and Victory ships. Many ships became too expensive to operate; insurance companies did not want to cover these old merchant ships. In most cases, they were sold for scrap. The reserve fleet was also being sold for scrap. What was once a proud fleet was now down to a precious few vessels. Some historic preservation and veterans organizations became interested in these ships and a handful were saved from the ship breakers. The following are the histories of five of these ships that have been preserved as floating museums to honor their service to the United States and to honor the mariners who sailed upon them.

The Liberty Ship SS Jeremiah O'Brien
The SS Jeremiah O'Brien is a World War II cargo ship and the product of a standardized design. The ship was named for Jeremiah O'Brien, a Revolutionary War hero who lived in Machias, Maine. In 1775, O'Brien led other residents of Machias in the capture of two British merchant ships. Using these captured ships, O'Brien captured the British armed schooner HMS Margaretta. This was the first naval action of the American Revolution.

The keel (the bottom beam or plate juncture that runs the length of a ship) for the SS Jeremiah O'Brien was laid at the New England Shipbuilding Corporation, in South Portland, Maine on May 6, 1943. She was launched on June 19, 1943. The ship was owned by the federal government and operated by Grace Line, Inc. For the next year, the ship carried ammunition and grain, as well as other dry cargo. In June 1944, the Jeremiah O'Brien supported the D-Day invasions by ferrying supplies between Great Britain and Normandy, France 11 times.

After the war, plans were made to transfer the ship to the U.S. Army for conversion to a hospital ship. The conversion never occurred and the ship was "mothballed" at the reserve fleet near San Francisco. In 1966, the U.S. Maritime Administration wanted to preserve a Liberty ship and chose the Jeremiah O'Brien. The ship was designated a National Historic Landmark (NHL) in 1986. NHLs are nationally significant historic places designated by the Secretary of the Interior because they illustrate the heritage of the United States. Over the years, the ship was restored and is now a museum in San Francisco, CA. She is only one of two Liberty ships still operational. The ship participated in the 50th anniversary of the D-day landings in 1994.

The Liberty Ship SS John W. Brown
The SS John W. Brown is a World War II cargo ship built by the U.S. Maritime Commission. In 1942, she was built in 41 days at the Bethlehem-Fairfield Shipyard in Baltimore, Maryland. She was launched on Labor Day, September 7, 1942. The ship was named after an American labor leader who organized workers in shipyards.

After being launched, the ship sailed to New York and departed on its maiden voyage on September 29, 1942 carrying supplies to the Middle East. In 1943, the ship was converted to carry troops as well as cargo. Later, the John W. Brown supported combat operations in the Mediterranean Sea. The ship was involved in the Allied landings at Sicily and Anzio in Italy, and southern France. After the war ended in Europe, the John W. Brown carried U.S. military personnel home.

In 1947, the Maritime Commission loaned the ship to New York City to use as a training vessel for high school students interested in maritime jobs. However, it became too expensive to run the school, and the ship was returned to the Maritime Commission and put into storage with the reserve fleet on the James River in Virginia. Historic preservation groups, including Project Liberty Ship and the Baltimore Museum of History (MD), wanted to protect the ship and it was transferred to them to turn into a museum in Baltimore, MD. She is one of only two Liberty ships still operational.

The Victory Ship SS American Victory
The SS American Victory was launched on June 20, 1945 at the California Shipbuilding Corporation yards in Los Angeles, California. The ship was named after American University in Washington, D.C. in honor of the school's contribution to war training and weapons research in both World War I and World War II. The ship's first voyage was in July 1945 carrying military supplies to Manila, Philippines.

After the war, the ship was used by the American Export Lines carrying cargo in support of the Marshall Plan, a U.S. economic diplomacy plan to help rebuild Western Europe after the war. On one of its many voyages, the American Victory was caught by ice in Odessa, Russia. Rather than wait for an ice breaker to clear the shipping lanes, the captain of the American Victory used her to break the ice!

In 1947, the American Victory was put into the reserve fleet. In 1952, the ship was brought out of "mothballs" to carry military supplies in support of the Korean conflict. After the Korean War, she was again sent to the reserve fleet. In 1963, the Navy planned to convert 15 Victory ships, among them the American Victory, as forward depot ships. These ships would be loaded with supplies and ammunition and placed around the world to support American troops if needed. However, the Navy canceled the plan in 1966 and that same year, the American Victory was again brought out of "mothballs" to support the Vietnam War. She carried military vehicles, telephone poles, explosives, and bombs.

In 1969, she was again put in the reserve fleet. In 1999, the American Victory was acquired by a preservation group and turned into a museum in Tampa, FL.

The Victory Ship SS Lane Victory
The SS Lane Victory was built by the California Shipbuilding Corporation in Los Angeles. She was launched on May 31, 1945. The ship was named for Lane College, which was established as a high school for black youths in 1882 by Isaac Lane, a bishop of the Methodist Episcopal Church at Jackson, Tennessee. The school grew into a prominent liberal arts college. On her first voyage, June 27, 1945, the ship carried supplies in the Pacific. She was operated by American President Lines.

In 1950, the Lane Victory was used to evacuate Korean civilians and U.N. personnel at Wonsan, South Korea during the Korean War. The ship also saw duty during the Vietnam War. In 1970, the ship was placed in the reserve fleet. Because of her excellent condition, the Maritime Administration decided to set aside the Lane Victory for preservation. In 1988, the Lane Victory was acquired by the U.S. Merchant Marine Veterans of World War II and turned into a museum in San Pedro, CA. In 1990, the ship was designated a National Historic Landmark.

The Victory Ship SS Red Oak Victory
The SS Red Oak Victory was built by the Permanente Metals Corporation, Shipbuilding Division Yard 1 in Richmond, California, across the bay from San Francisco. Her keel was laid August 15, 1944 and she was launched November 9, 1944. She is one of the last ships built by the Richmond Shipyard during World War II. The ship was named after the community of Red Oak, Iowa, which suffered the highest per capita casualty rate of any American community during World War II. On December 5, 1944, she was commissioned as the USS Red Oak Victory (AK-235) for the the U.S. Navy to be used as an ammunition carrier.
In January 1945, after sea trials, she loaded over 10,000 tons of ammunition from the Port Chicago Ammunition Depot, Concord, California and departed for Pearl Harbor, Hawaii. In February 1945, she steamed to a remote area of the South Pacific called Ulithi Atoll where the worlds largest formation of Allied forces had amassed for the invasion of Japan. From March to May 1945, the USS Red Oak Victory (AK-235) replenished numerous vessels of the Pacific fleet. From June to October 1945, she supported the liberation of the Philippine Islands. In November 1945, she headed home to Seattle, Washington were she was decommissioned on May 21, 1946 and returned back to the U.S. Maritime Commission.

In May 1947, she was leased to the Luckenbach Gulf Steamship Company, Seattle, Washington. She made several voyages, most notably supporting the UN forces engaged in the Korean War with military cargo. From 1957 to 1965 she was in storage by the U.S. Maritime Commission. In December 1965, she was leased to the American Mail Lines and until December 1968, supported U.S. forces engaged in the Vietnam War. She was placed back into storage until September 1998, where she was obtained by the Richmond Museum Association to be restored back to her original operational launch condition. Today, the Red Oak Victory is an integral part of the Rosie the Riveter/World War II Home Front National Historical Park.

Questions for Reading 3
1. What was some of the cargo these ships carried?
2. Looking at a world map or atlas, locate some of the places to which each of these ships carried cargo. Does this give you a better appreciation for the mission of the seamen who served in the Merchant Marine? Why or why not?
3. Unlike the Liberty ships, which were built to be expendable, the Victory ships were designed to last for at least 20 years after being built. What examples can you find in the reading to support this?
4. Of the thousands of Liberty and Victory ships built, only a few remain. Why do you think it is important to preserve these ships?

Your Merchant Marine Has Grown

American merchant shipyards have built four ships for every prewar ship we had. Our fleet of Liberty, Victory, C-type and other vessels reached an all-time high of more than 3,500 dry cargo vessels, and more than 900 high-speed tankers.
This huge fleet, in 1944, moved out of the United States more than 72 percent of 78,500,000 tons of cargo shipped. Three percent were carried by the U.S. armed forces and 24 percent by the combined tonnage of other United Nations.
Transfer of troops and supplies from Europe to the far Pacific, over sea lanes ranging from 12,000 to 18,000 miles, will demand maximum efficiency in the use of our huge fleet under control of the War Shipping Administration and the United Nation's pool.

Photo 3: North Atlantic Convoy, 1941.

Photo 3 shows a convoy of ships in the North Atlantic. Some of the ships in the convoy are Liberty ships. In 1941, The United States established the forward military base in Argentia, Newfoundland to support convoy escorts and patrol aircraft. The photograph was taken from an airplane assigned to the USS Albemarle (AV-5), a seaplane tender (a ship built to house and support seaplanes), in October 1941. At the time the photo was made, the Albemarle was based at Argentia.

In the early years of World War II, German submarines, also known as U-Boats, threatened ships traveling across the Atlantic Ocean. Many cargo ships were sunk by the U-Boats. The United States and the Allies developed many ways to protect ships carrying supplies to Great Britain and the Soviet Union. Some of the many innovations that came out of World War II to locate submarines include radar, sonar, and high frequency direction finding.

Because ships traveling alone were almost certain targets for submarines, the U.S. and her Allies grouped the ships together in huge convoys. The Navy and Coast Guard escorted the convoys with destroyers. Unlike modern submarines, which can stay submerged for months at a time, the submarines in World War II spent most of their time on the surface and submerged only when attacking ships or evading detection. In areas that were close to land, airplanes were used to scout for submarines. Many of these scouting planes also carried bombs so they could attack detected enemy submarines.

Questions for Photo 3
1. Using an atlas, locate Newfoundland, Canada. Look at Map 2. Where is Newfoundland located, in relationship to the line between New York and Great Britain? Why did it make sense to base convoy escorts and patrol aircraft, such as the seaplanes from the USS Albemarle, in Newfoundland?
2. Why would grouping ships together in convoys help protect ships from submarines?
3. Photo 3 shows part of the wing of the patrol aircraft. In what ways did the patrol aircraft help protect ships carrying supplies?

Putting It All Together


The Liberty ships and Victory ships were built in order to move troops and supplies during World War II. They were built in great numbers to counter the threat from submarines and to ensure that the flow of men and material was unhindered. The following activities will help students discover more about Liberty and Victory ships and the role their community and its residents played during World War II.

Activity 1: Pay Tribute to Local History
Have students design a postage stamp depicting an important event that happened in your community. Encourage students to be creative with designs and color. Students should share their "stamps" in class and hold a class discussion on why they chose to commemorate that particular event.

Activity 2: Serving the War Effort
By using simple designs, perfecting mass-production techniques and building the necessary shipyards, the U.S. was able to produce the massive fleet of merchant ships needed to win World War II. However, there were not enough workers for all the new shipyards. Many men who could have built ships were serving in the armed forces. As a result of this labor shortage, many factories and shipyards hired women, minorities, and men unable to go to war to work on the assembly lines and in the shipyards to manufacture the products needed to prosecute the war. The women were given the nickname "Rosie the Riveter" after a worker in a popular song.

Ask students to locate persons in the community or their families who worked in the farms, factories and shipyards during World War II. Students may find that local organizations that serve veterans and senior citizens are a good resource for locating these individuals in their communities. Organize a class project to participate in the Veterans History Project of the Library of Congress by interviewing these persons and donating the interviews to the Library of Congress. See the Library of Congress Veterans History Project website at [http://www.loc.gov/folklife/vets/], or write to The Veterans History Project, American Folklife Center, Library of Congress, 101 Independence Ave., SE, Washington, D.C. 20540 for more information. The project website offers sample interview questions for civilians who worked in support of the United States during the war. A free "Field Kit" is also available with tips for interviewing. You can download the kit for free on the project's website [http://www.loc.gov/vets/kitmenu.html].

Activity 3: Carrying the Supplies
The Liberty ships and Victory ships carried many different types of important supplies in support of the war including food, fuel, vehicles, ammunition, and spare parts. Ask students to locate farms or factories in your community that supplied the war effort. Have them research how they supported the war. The local historical society or library's local history section is a good place for students to start their research. Students may need to look at old phone books, city directories, or newspapers to determine which businesses were active in their community during the war and whether they were involved in war production. Students should share the information they have discovered in the form of papers, project boards, computer slideshows, skits, or oral presentations.

Liberty Ships and Victory Ships, America's Lifeline in War--

Supplementary Resources

Liberty Ships and Victory Ships, America's Lifeline in War will help students in understanding how the United States mobilized a massive construction effort to build a large merchant fleet to serve in war and peace. Of the thousands of ships built during World War II, only a small number remain. Those interested in learning more will find that the Internet offers a variety of materials about the people, vessels, and organizations associated with this great accomplishment.


Rosie the Riveter/World War II Home Front National Historical Park
Rosie the Riveter/World War II Home Front National Historical Park is operated as a partnership between the National Park Service, the City of Richmond, the Rosie the Riveter Trust and the Richmond Museum of History. The park opened in 2000 and is still in development. The park preserves and interprets the history of the men and women who worked at the factories and shipyards in and around Richmond, California in support of World War II. Among the many units of the park is the site of the Richmond Shipyard (which built many of the Liberty and Victory ships), the automotive plant (which produced military vehicles), the Rosie the Riveter Memorial, the Liberty Ship Memorial and the SS Red Oak Victory (a World War II era Victory ship). The SS Red Oak Victory is currently undergoing restoration, please check the website for updates.
