For the first time published archival documents of a prominent figure in the white military emigration, Major General A.A. von Lampe (1885-1967) contains his diary entries, official and private letters, reports, notes on negotiations with Hungarian politicians and on the internal life of the Russian colony in Hungary. These valuable materials are an important source for studying the history of the Russian Diaspora and, in particular, the Russian All-Military Union, which von Lampe headed until 1967.
