[11] The defeat was one of the reasons Janusz Radziwiłł and several other Lithuanian magnates surrendered the Grand Duchy to Sweden at the Union of Kėdainiai.

The morale was further damaged by the order of king John II Casimir Vasa to royal troops (about 5,000 men) to retreat to Marienburg.

[4] Lithuanian commanders hetman Janusz Radziwiłł and treasurer Wincenty Korwin Gosiewski could not agree on defense.

Most valued treasures, including the coffin of Saint Casimir, main books of Lithuanian Metrica, and valuables from Vilnius Cathedral, were transported outside the city.

[13] Radziwiłł took up a defensive position on the northern shore of the Neris river near the present-day Green Bridge to cover the evacuations.

[9] The invaders not only took valuables such as furniture or silverware, but also smashed altars, desecrated graves (including silver sarcophagus of the Sapieha family), and tore down decorative elements (such as marble columns of the Radziwiłł Palace).
