Polish Mounted Police Patrol in Occupied Český Těšín (October 1938)

This striking historical photograph, preserved in the National Digital Archive of Poland (NAC) and dated October 11, 1938, captures a Polish mounted police officer patrolling the streets of Český Těšín following the Polish military annexation of the Zaolzie region.

A celebratory banner overhead proclaims “Witajcie! Od dziś wreszcie razem!” (“Welcome! From today, finally together!”), reflecting the official state narrative of the intervention during the partition of Czechoslovakia.

The Background of the Teschen Conflict

The geopolitical status of the region had long been a point of friction in Central Europe:

  • The 1920 Division: Originally a unified Austrian-Hungarian town, Teschen was split along the Olza River in 1920 by an international decision, dividing the historic municipality into Polish Cieszyn on the east bank and Czechoslovak Český Těšín on the west.
  • The 1938 Ultimatum: Capitalizing on the Munich Agreement and the severe weakening of Czechoslovakia in September 1938, the Polish government issued a 24-hour ultimatum demanding the immediate handover of Zaolzie, backed by troop concentrations on the border.
  • Military Takeover: On October 2, 1938, Polish operational units under the command of lateral commanders crossed the Olza River, occupying approximately 805 square kilometers of territory containing vital coal mines and heavy industry.
  • Archival Documentation: Official state photographs from the period, such as this NAC record, document the triumphalist atmosphere in Warsaw regarding the territorial acquisition—an alignment of actions with Nazi Germany during the dismemberment of the Czechoslovak state.

Historical Repercussions

While celebrated domestically in late 1938, the annexation of Zaolzie severely isolated Poland diplomatically and created profound regional animosities. Less than a year later, following the outbreak of World War II in September 1939, the region was swiftly absorbed into Nazi Germany as part of Reichsgau Oberschlesien.
