But the main concern of the [[House of Ascania]] was obvious to all: the union of the Kingdom of Poland, and that sooner or later Przemysł II would claim the lands seized by the Margraves in Greater Poland. After 25 January 1296 the King left his capital, and surely by 3 February he was in [[Pyzdry]]. For the last days of the Carnival (between 4–7 February) Przemysł II decided to spend these festivities in the town of [[Rogoźno]].

They were carefully informed by traitors from Przemysł II's inner circle about the King's itinerary for the next few days. In the meanwhile, Przemysł II participated in the traditional tournaments and religious services of the Carnival. The security guard of the King became weaker, especially since probably 8 February. On that day began the forty days of [[Lent]], and before heading out again the entourage wanted to rest. The plan of kidnap the King by the Margraves of Brandenburg was widely detailed by the "Roczniki małopolski". They probably wanted to obtain from Przemysł II the resignation of Pomerelia and with this, his plans for the unification of Polish Kingdom. The contingent was probably consisted by dozens of people, because made the kidnapping in hostile territory require adequate preparation.
