During World War II, on 2 September 1939 at around 19:00, the ethnic Germans of Święciechowa carrying Nazi flags were mistaken by Polish soldiers for the Wehrmacht.

As a result, a gunfire incident occurred in this village.

The Polish forces eventually succeeded in stopping the revolt.

On 4 September 1939, Święciechowa succumbed to German occupation after the retreat of Polish soldiers in the area of Leszno.
