June 1610 CE
Russian forces under Grigory Voluyev, coming to relieve Smolensk, fortify the wooden fort at Tsaryovo–Zaimishche (Carowo, Cariewo, Tsarovo–Zajmiszcze) to bar the Poles' advance on Moscow.
The Siege of Tsaryovo begins on June 24.
However, the Russians are not prepared for a long siege and have little food and water inside the fort.
Voluyev sends word for Dmitriy Shuisky (Tsar Shuiski's brother) to come to their aid and lift the siege.
