On January 13, 1943, Sikorski and others signed a formal Declaration of War Crimes after the news of the massacre.
In 2008 the Polish government exhumed and tested Sikorski's body, concluding that the injuries he suffered were consistent with an airplane crash and ruling out conspiracy theories that claimed he had been killed otherwise.
The governments of both Russia and Britian have refused to release classified documents related to the affair; on Britain's side, at least, this decision may have been made to protect the identities of their spies during the war.
