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.
Polish rebels observed the enemy from a distance, and when the Russians had left Słomniki, they set out on their return journey.
