In an effort to take back their city after 5 years of German occupation, struggling Poles rebelled in what is known as the Warsaw Uprising. Barely armed (it is said 1 in every 10 Poles had a rifle) and with the Germans brutality (going door to door, shooting every inhabitant including elderly, sick, women, and children), it was a losing battle from the start. Remnants can be seen throughout the city, especially in the concrete.
