Gavrilo Princip
In general we don't build monuments to political murderers in Poland. We can appreciate the chain of events and the eventual outcome of the murder, but we don't usually honour the murderer.

Don't forget that in Kosowe Pole Polish knights fought side-by-side with Serbians. That is why, until this very day, Poles say that "Kosowo to Serbia". We have very good memories. Like elephants.
Polish-Russian victory over Swedes?
What?
Let's see: first northern war (7-year war) - Russia was
on the Swedish side, in the Inflanty war Russia didn't take part at all, then 1617-18 totally between Poland and Sweden, the next one 1625-26 without Russian participation, in the Vistula estuary war we were aided by Austria (but we had to pay half a million zlotys for it - a lot of money back then), in the VI Polish-Swedish war - the famous Deluge - Russia was actually
on the Swedish side again. Hmm... you must be thinking about the III Northern War in which accidentally Poles and Russians were at the same side for some time. Nothing to build monuments for really.
