The Siege of Pskov took place during the final stage of a war that fought for control of what area?
Livonian War The Livonian War (1558–1583) was fought for control of Old Livonia (in the territory of present-day Estonia and Latvia), when the Tsardom of Russia faced a varying coalition of Denmark–Norway, the Kingdom of Sweden, and the Union (later Commonwealth) of the Grand Duchy of Lithuania and the Kingdom of Poland.
Suchan Valley Campaign The Suchan Valley Campaign was the clearing and occupation of the mining region around the Russian town of Suchan (currently Partizansk, Russia) in a climatically-unforgiving region of Russia's Siberia during the Russian Civil War. A relatively clean sweep, the operation inflicted heavy casualties on the Bolsheviks.
