It has been 40 years since the outbreak of the war. A ceremonious change of guards at the Tomb of the Unknown Soldier. Today we are remembering the heroic stance of the Poles: the battle of Narvik, Great Britain, Lenino, Monte Cassino, July of 1944. Chełm and Lublin, the first liberated Polish cities. The decisive offensive starts by the Oder river. The annual military manoeuvres of the Polish Army.
