As the battle over the Bzura boiled over...
The major part of the permanent exhibition is made up of shooting weapons, equipment, ordnance, uniforms, photographs and documents of the Polish Army soldiers who fought in the Battle of the Bzura. These items, hidden on the battlefield by soldiers and local people, found by the Museum staff, donated to its collection by the families of those who died in the battle and the inhabitants of the Sochaczew Region, make up a collection - one of the richest in the country.
