Siege of Zamość

Siege of Zamość was part of The Deluge.

Prelude
In the summer of 1655, the joint Russo-Cossack army approached the fortress, but did not try to capture it. During the Deluge in 1655, when the rest of Poland quickly surrendered to Charles X Gustav of Sweden, Lord of Zamość, Jan II Zamoyski, decided to support King John II Casimir of Poland.

Siege
On February 25, 1656, Swedish troops appeared at the gates of the stronghold. According to a legend, when Swedish representatives came to the town and proposed the capitulation of the fortress, Jan ‘Sobiepan’ Zamoyski answered: "I am the Lord for myself and I will not give Zamość to the Swedes".

The Swedes began with artillery barrage, but due to lack of heavy guns, it was not successful. Within a few days, Charles X Gustav realized that capturing Zamość, whose fortifications had been strengthened since 1648, was impossible, and on March 1, the invaders withdrew.

Aftermath
Next year, the Transilvanian army under George II Rákóczi appeared near Zamość, but it did not even try to capture the mighty fortress.

In the last stage of the war, Zamość was a prison for high-ranking officers of the Swedish Army. Among those kept there, was Field Marshal Arvid Wittenberg, who died in prison of natural causes.

In popular culture
Swedish siege of Zamość was described by Henryk Sienkiewicz, in his popular book The Deluge (novel).
