Kmita and his band make their way to the sacred monastery of Jasna Gora and he personally warns the prior, Father Kordetski. After a somewhat hostile reception, especially from a suspicious Charnyetski, the fortress takes defensive measures orchestrated by Zamoyski and Charnyetski, using cannon delivered earlier from Cracow. The Swedish force led by General Miller arrives, terms of surrender are rejected and the siege commences – against the advice of the highly experienced Colonel Sadovski – on 18 November. Kmita himself takes charge of firing one cannon and successfully destroys many Swedish cannon and troops. The besieged also make a surprise sortie on November 28 and destroy a further two Swedish cannons. Charnyetski is brought round by the Lithuanian's skill and courage, particularly when Kmita defuses a Swedish cannonball by removing its charge. Prior Kordotski requests Kmita to dedicate the iron ball to the Most Holy Lady once the enemy have left the field.
