27 September: Territorial Defence Day and underground history

Poland’s Territorial Defence Forces mark their day on 27 September. The defence ministry links the date to the anniversary of the Polish Underground State’s creation. It offers an opportunity to explore the history behind symbols used by the modern formation.

The meaning of 27 September

The ministry notes that the Territorial Defence command inherits the traditions of the Home Army’s headquarters. Its account connects the Fighting Poland symbol with remembrance of the underground and service to the country.

The Ossów ceremony was announced for Friday

The ministry announced a ceremony at the Museum of the Battle of Warsaw 1920 in Ossów for Friday 25 September at 11:00. That announcement should not be read as Sunday’s programme: an observance date and an individual ceremony can differ.

Finding a current local programme

Before attending a museum or ceremony, consult the organizer’s current schedule. Check whether the notice invites the public or addresses accredited journalists; a press announcement alone does not establish unrestricted admission.

For a conversation about history at home, choose a map, photograph or document with clear provenance. Separate the original caption from later commentary. This makes it easier to ask concrete questions about people and events rather than recirculate anonymous graphics.
