There is simply a letter from the employees of the Military Historical Office in defence of Prof. Sławomir Cenckiewicz

Professor Sławomir Cenckiewicz is to face charges in connection with presenting the alleged "Tusk Line" to the public, i.e. plans for the "defense" of Poland on the Vistula River, which means surrendering east Polish territories in the event of a Russian invasion. The papers were previously declassified by Błaszczak's Ministry of National Defense, and the WBH headed by prof. Sławomir Cenckiewicz only performed an executive function in relation to the Ministry of National Defense's decisions.
