Molotov-Ribbentrop Pact is signed by Nazi Germany and the Soviet Union; this is a neutrality pact, delineating the spheres of interest between the two powers; it provides a written guarantee of non-belligerence by each party towards the other; and declares commitment that neither government will ally itself to or aid an enemy of the other party.
World War II begins; Germany invades Poland from the west.
Lavrentiy Beria, head of NKVD, organises two NKVD operational groups to be based in Kiev in Ukraine and Minsk in Belarus, for near-future deployment to eastern Poland to arrest “resistance elements”. The two groups in Ukraine and Belarus are led by Ivan Serov and Lavrentiy Tsanava, respectively.
The Soviet Union invades Poland from the east. Around 25,000 Polish military officers, senior NCOs, police officials, intellectuals and priests (ie Polish Elite) are arrested and interned on the territory which is now western Ukraine and western Belarus. They are either imprisoned locally or sent eastward to three special prisoner-of-war camps administered by the NKVD in Kozelsk and Ostashkov in western Russia and Starobilsk in eastern Ukraine.
October 1939
Beria issues an order that the Polish Elite should be separated from among the hundreds of thousands of other Polish POWs.
February 1940 through June 1941
Between 1-2 million Poles from the Kresy (eastern Borderlands), Ukraine and Belarus are deported to Kazakhstan and other remote Soviet locations.
The Soviet Politburo declares most Polish POWs and some of the Elite in captivity "enemies of the Soviet Union" and orders death sentences for all of them, fearing that, if released, they will organise resistance movements against the Soviet occupation.
Spring 1940
Over 20,000 Polish Elite are massacred by the Soviet NKVD killing squads. The murders, carried out with shots to the back of the head, take place in the Katyń forest in western Russia and other locations.
Beria orders the decoration of 125 NKVD staff involved in the Katyń operation.
Germany attacks the Soviet Union via Soviet-occupied Poland.
June 1941
As a result, the Soviets join the Allies in the war against Hitler.

An agreement is signed between the Polish Government-in-Exile (located in London) and the Soviet Union whereby the Soviet Government renounces territory gained under the Molotov-Ribbentrop Pact and grants amnesty to Poles held prisoner in the Soviet Union.

A Polish Army on Soviet territory is to be formed from these released prisoners.

The Polish General Władysław Anders is appointed Commander of the Polish Army on Soviet territory.
When General Anders requests that 15,000 Polish prisoners-of-war whom the Soviets had once held at camps near Smoleńsk be transferred to his command, the Soviet government informs him that most of those prisoners have escaped to Manchuria and cannot be located.
March 1942
Polish workers, stationed near Katyń, discover graves. The Germans are informed but do not announce it until the following year.
Nazi Germany's propaganda chief, Joseph Goebbels, announces the German discovery of mass graves in the Katyń Forest near Smoleńsk, in their area of occupation, containing a total of 4,443 corpses, of which over 1,700 are bodies of Polish officers who were shot in the back of the head. Goebbels hopes public knowledge of the Soviet crime will sow distrust between the Soviet Union and the Western Allies and weaken their alliance.
Polish Red Cross Technical Commission arrives at Katyń.
Churchill privately acknowledges to Polish officials that the Soviet regime has probably committed the Katyń murders.
The Polish Government-in-Exile in London, under the leadership of Władysław Raczkiewicz, Władysław Sikorski and Stanisław Mikołajczyk requests the International Red Cross to investigate the matter.
Churchill, realising that bringing up the issue of Katyń at this stage would jeopardise the Alliance with the Soviet Union, informs Stalin that Great Britain will oppose any investigation of Katyń.
The Soviet Government breaks diplomatic relations with the Polish Government-in-Exile in London. The Soviets then set about establishing a Polish Government-in-Exile composed of Polish communists.
As part of the Nazi propaganda effort, the Germans bring a group of American and British POWs to Katyń, including US Lt. Col. John H Van Vliet as well as other groups, to see the remains of the Poles in the mass graves, in an advanced state of decomposition. The International Medical Commission completes its investigation on the Katyń Massacre, concluding that the Soviet Union is responsible for the atrocity and reporting that the graves contain the bodies of 4,143 officers, of whom 2,914 are identified by documents in their uniforms. It is the commission's opinion that the men were shot to death in the Spring of 1940. The Soviet authorities flatly reject the accusations of the German-appointed commission, arguing that the Germans themselves committed the deed when they occupied the area in July 1941.
General Sikorski dies in a plane crash under suspicious circumstances.
November 1943
Several months after the Red Army liberates Smoleńsk, the Soviet Union appoints an NKVD commission of inquiry of its own. It begins top secret work with local NKVD falsifying evidence and removing all evidence of Soviet guilt, blaming the Germans for the Katyń murders.
Memo by Owen O’Malley (British Ambassador to Polish Government-in-Exile) asserts Soviet guilt for the Katyń massacres but ends with the words, “Let us think of these things always but speak of them never.
Dr Jan Zygmunt Robel, a Polish forensic scientist, begins work on the materials recovered from the Katyń pits.
Nikolai Burdenko (President of the Soviet Academy of Medical Sciences), Chairman of the Extraordinary State Commission for the Katyń massacre conducts investigation “Soviet Burdenko Commission” at Katyń site. It claims that the Polish Officers were shot by the Germans in 1941.
May 1945

World War II in Europe ends.

Upon being freed, Lt. Col. John H. Van Vliet gives his first report to US Army intelligence on what he witnessed at Katyń, a report that disappears until the release of US Archive files in 2012.


Robel’s Archive is lost in a fire during transportation to the West although some material, including prisoners’ diaries are either hidden in Poland or spirited away to London.

Dr Roman Martini, a Polish Prosecutor, begins his investigation into the Katyń massacre for the new Polish Communist authorities.

Dr Martini is murdered.
Memorial Obelisk is erected at the Katyń site with an inscription in Polish and Russian, blaming the Germans and citing Autumn 1941 as the date of the massacre.
01-02 July 1946
At the International War Crimes Tribunal at Nűremberg, the Soviet Prosecutors attempt to add responsibility for Katyń to the list of charges against the senior surviving Nazi leaders. However, the defence is able to call witnesses to refute the accusations of German responsibility. As a result, the Tribunal does not add Katyń to its list of charges, but neither does it make any judgement regarding ultimate responsibility.
“The Katyń Murder in the Light of New Evidence” is edited by Józef Mackiewicz, with a foreword by Władysław Anders.
early 1950
A United States Congressional Inquiry finds the NKVD responsible, and most Western historians now believe that the massacre was committed at the behest of the Soviet authorities.
The US Congress sets up a committee to investigate the Katyń crimes after questions about the whereabouts of the missing Van Vliet report from 1945. Even ahead of the formal establishment of the committee, Van Vliet in 1950 makes a second written report on his impressions from Katyń.
The Congressional committee concludes that there is no question that the Soviets bear blame for the massacre. It faults Roosevelt's administration for suppressing public knowledge of the truth. The report also says it suspects that pro-Soviet sympathizers within government agencies buried knowledge about Katyń. It expresses anger at the disappearance of the first Van Vlietreport and says: "This committee believes that had the Van Vliet report been made immediately available to the Department of State and to the American public, the course of our governmental policy toward Soviet Russia might have been more realistic with more fortunate post-war results." However, Soviet leaders continue to insist that the Polish officers found at Katyń were killed by the invading Germans in 1941. This explanation is accepted without protest by successive Polish communist governments until the late 1980s, when the Soviet Union allows a non-communist coalition government to come to power in Poland, as a result of the activities of Solidarność.
The Polish Government officially accuses the NKVD of perpetrating the Katyń murders. In 1989, Mikhail Gorbachev reveals to the world that in March 1940 Joseph Stalin gave orders for the execution of 25,700 Polish Elite. He also admits that two other mass graves have been found in the Katyń area.
April 1990

In keeping with the reformist Soviet leader, Mikhail Gorbachev's Glasnost policy, the Soviet Union releases documents indicating its responsibility for the massacre at Katyń, and uncovers further mass graves in the area. Gorbachev hands lists of murdered POWs to Polish President Jaruzelski in Moscow.
