March 1634 CE
Shein had begun surrender negotiations in January 1634, and by February they were in full swing.
The Russians finally signed a surrender treaty on February 25, 1634, and on March 1 they vacate their camp.
Under the surrender terms, the Russians have to leave behind most of their artillery but are allowed to retain their banners after a ceremony in which they are laid before King Władysław.
They also have to promise not to engage Commonwealth forces for the next three months.
Shein's forces number around twelve thousand at the time of their capitulation, but over four thousand, including most of the foreign contingent, immediately decide to defect to the Commonwealth.
