Until those Olympics Poland had 8 medals combined in the Winter Olympics (we never been good in winter sports)
But Vancouver 2010 was incredible, 6 medals 3 silvers, 2 bronzes and an Amazing Gold of Justyna Kowalczyk (she is my hero, 3 medals this olympics) for 30 km cross country skiing , with the best finish you probably see in this (boring) sport.
We did well in Ski Jumping, and suprisingly got a medal in speed skating (no one expected that)
