On 20 October 1655, Grand Hetman of Lithuania Janusz Radziwiłł announced in the agreement of Kėdainiai with the Swedes the dissolution of the union with the Polish Crown and a bond between the Grand Duchy of Lithuania with Sweden. How do you assess Radziwiłł’s action?

It was an ostentatious treason that cannot be explained in any way.
It was a desperate attempt aimed at saving the Grand Duchy of Lithuania threatened by Russia whose troops had occupied Vilnius. Additionally, the Grand Duchy could not count on aid from the Crown’s troops defeated by the Swedes.
