The death of False Dmitry and widespread chaos proved reason for Poland to prepare an invasion. Prior raids between 1605 and 1609 were conducted by Polish nobles or adventurers along with hired cossacks and foreign mercenaries. Sigismund's primary intention was to destroy the Russian state and impose Catholicism with the use of force or terror if necessary. Lew Sapieha, Grand Chancellor of Lithuania, sought neutrality by proposing to Boris Godunov an "eternal" peace treaty between Russia and Poland–Lithuania, but the idea did not gain support and was declined.
