Records Relating to the Katyn Forest Massacre at the National Archives

Summary of events

Nazi Germany and the Soviet Union each invaded Poland in September of 1939, having divided the country into separate spheres of influence under the Molotov-Ribbentrop Pact. While the Germans began a massacre of Jews and Poles in western occupied Poland, the Red Army arrested and imprisoned thousands of Polish military officers, policemen, and intelligentsia during their occupation of eastern Poland. Prisoners of war and civilian internees captured by the Soviets were placed in several camps in the western USSR, run by the Soviet People's Commissariat for Internal Affairs, or NKVD, a predecessor organization to the modern FSB-camps including Kozielsk, Ostashkov, and Starobielsk.

In April 1943, in the Katyn Forest near Smolensk in the Soviet Union, occupying German troops discovered eight large graves containing the remains of thousands of the Polish Army officers and intellectual leaders who had been interned at the prisoner-of-war camp at Kozielsk. Bodies of the prisoners who had been housed at Ostashkov and Starobielsk were discovered near Piatykhatky and Mednoye, respectively. Collectively, these murders are known as the Katyn Forest Massacre.

An internationally-staffed medical commission organized by the Germans excavated the area in early spring 1943. As the excavation progressed, the Germans brought in several groups of observers, including some American prisoners-of-war. This commission determined that the massacre occurred in 1940, when the area was under Soviet control -- a determination which was then used as a propaganda tool intended to disrupt the alliance between the US, Great Britain, and the Soviet Union. This effort was successful in part, as Polish intelligence sources immediately blamed the Soviets for the atrocities, leading to a break in diplomatic relations between Poland and the USSR.

After their recapture of Smolensk in the autumn of 1943, the Soviet government organized its own excavation. This second enquiry concluded that the Polish prisoners of war had been captured and executed by invading German units in August 1941.

Berry, American Consul General, Istanbul, Turkey Forwarding German Propaganda Photographs and Documents Relative to the Alleged Bolshevik Massacre of Polish Officers at Katyn (1943).

The official American response at the time was one of non-involvement. In a June 1943 telegram to Churchill, Roosevelt expressed approval that the British approach to Stalin was grounded "upon the obvious necessity of creating the most favorable conditions for bringing the full weight of the armed forces of all the United Nations to bear upon the common enemy....The winning of the war is the paramount objective for all of us. For this unity is necessary."

Later, on September 18, 1951, the United States House of Representatives established the Select Committee to Conduct an Investigation and Study of the Facts, Evidence, and Circumstances of the Katyn Forest Massacre, known as the Madden Committee after its chairman, Rep. Ray J. Madden of Indiana. The committee assembled records relating to the massacre and its aftermath, including records from the files of the State and War Departments, in addition to hearing extensive witness testimony. Their purpose was to determine which nation was responsible for the atrocities and whether any American officials had engaged in covering up the massacre.

The Madden Committee determined unanimously that the NKVD was responsible for the executions, and recommended a trial before the International World Court of Justice. The question of an American cover-up was less clear cut. In its final report, the committee concluded that American officials failed to properly evaluate and act upon clear danger signals in Russian behavior evident as early as 1942. In addition, the committee found that American policy toward the Soviet Union might have been different if information deliberately withheld from the public had been made available sooner.

In September 2011, the National Archives responded to a letter to President Barack Obama by Representative Marcy Kaptur and Representative Daniel Lipinski requesting the identification, declassification and public release of all records of permanent value in the custody of the US Government relating to the events at Katyn. The National Archives via the National Declassification Center subsequently made it a priority to process and declassify all known documents related not only to the initial events of the 1940s but also to the Madden Committee and the ongoing American response. This special effort has led to the declassification of over a thousand pages not previously released to the public, and the launch of a project to highlight Katyn material declassified by the National Archives over the previous few decades.

The following two maps are each part of a larger report, written between December 1944 and February 1946 by the Council of Ministers of the Polish Government in London, and entitled "Facts and Documents Concerning Polish Prisoners of War Captured by the U.S.S.R. During the 1939 Campaign".

This report was transmitted by a member of the Polish government in exile, Lt. Gen. M. Kukiel, via the American military attaché's office in London, to Maj. Gen. Telford Taylor in December of 1947, and eventually appeared before the Madden Committee, having been mistaken for the lost "van Vliet report" (Record Group 319, Department of the Army, Office of the Assistant Chief of Staff for Intelligence, Permanent Retention Files, 1918-1963, 319-5937-1, Report - Facts and Documents Concerning Polish Prisoners of War Captured by the U.S.S.R. During the 1939 Campaign, 1946). [National Archives Identifier 6256898] The details of the transmittal of this report are described in Record Group 319, Department of the Army, Office of the Assistant Chief of Staff for Intelligence, Permanent Retention Files, 1918-1963, 319-5937-3-3, Report - Polish Prisoners of War Captured by U.S.S.R.

Exhibit XVII. This map was drawn by Gregor Slowenczik, a reporter for the German Army who had documented the Katyn excavations and provided material to the US Counter Intelligence Corps in 1946. After his death, his wife, Maria (nee Wagner) provided this map, along with photographs and other testimony remaining from her husband's visit to Katyn, to the United States Forces in Austria.

Assistance from NARA Staff

As noted in our FAQs, communicating with the Reference Staff at the National Archives before you visit is likely to improve the results of your research experience. This is especially true in the following instances:

  1. if the records are dated from the 1960s and later
  2. if you are dealing with agencies involved with foreign affairs, intelligence, and law enforcement
  3. if you do not have precise file number citations to the files of various agencies or National Archives record group and entry numbers
  4. or if you are unsure that records exist

While the reference staff cannot undertake your research for you, they can do some preliminary work in order to identify the file categories in the Department of State’s central files likely to contain documentation of interest or locate other series with pertinent records. Doing that work takes time, however. It cannot be done effectively while you are waiting in the Research Room.

Reference staff is available at the National Archives at College Park Research Room from 9:00 a.m. to 5:00 p.m. Monday through Friday, except legal holidays. For those wanting a more in-depth explanation of the records or with difficult or advanced research projects, a specialist in foreign affairs records is available for consultation. The specialist is in the National Archives at College Park Textual Research Room every Tuesday morning from 9AM to 10AM and can answer questions about the organization and content of the records and help you plan a research strategy.
