On August 2, 1914, upon order of Józef Piłsudski, the seven uhlans crossed the border between Austrian Galicia and Congress Poland, on a mission to gather information about Russian forces in the area of Miechów and Jędrzejów.
Other members included: On August 3, 1914 after midnight, the group, armed with rifles and pistols, and equipped both with civilian clothing and uniforms, crossed the border in two horse-drawn britzkas (carriages).
Their plan was to penetrate the area, destroy a Russian Army mobilization office in Jedrzejow, capture horses, and become a cavalry unit.
In the morning, the seven men arrived at a manor house in Goszyce, which belonged to Zofia Zawiszanka, a member of Polish patriotic organizations and personal friend of Zygmunt Karwacki.
The leader of the group, Wladyslaw Prazmowski, came to the conclusion that the mission was accomplished and decided to return to Galicia, via Słomniki.
