Heros and Saints of the Ukraine

I'm sure this guy is important as he had pride of place in the biggest square in town but I'm having trouble reading what's written on the stone, although according to the guide book it has something to do with beating the Polish. Instead of entering the next cathedral we climbed the bell tower to get a good view out over the city.
Looking out towards Saint Michael's Cathedral and the river.
St Sophia's Cathedral and the residential part of the city.

We walked down to St Michael's Cathedral where they were setting up for some sort of celebration, hence the flags.
Saint Andrew's Cathedral was just round the corner heading into the chilled part of the city with cobbled streets and stalls. I stopped at one stall selling badges and bought the one memento of my East European jaunt, a pin badge of Lenin with the motto always ready, although for what I'm not sure.
I'm starting to feel out of place. Enough of the saints, where the sinners at?
