On 25 January 2017 the Witold Pilecki Center for Totalitarian Studies signed an agreement with the Hoover Institution, pursuant to which “Chronicles of Terror” will be supplemented by depositions relating to Communist crimes, taken from the archives of Gen. Anders’ Army.[5][6] After World War II, documents containing the accounts of Poles – both soldiers and civilians who left the Soviet Union together with the Polish Army – were deposited with the Hoover Library, for it was feared that they could have been seized by the Communist authorities.
