prosperity of Tarnowskie Góry was abruptly halted by the Thirty Year War (1618–1648), and in 1676–77 its population was farther decimated by an outbreak of plague (which two years later reached the Austrian capital). In 1683, Polish King John III Sobieski rested in town on his way to the Battle of Vienna (where he led the famous Hussars branch of Polish cavalry to victory in defeating the Ottoman army and stopping the progress of their European invasion). In Tarnowskie Góry, Polish nobility welcomed the newly elected kings Augustus II the Strong and Augustus III of Poland, in July 1697 and January 1734, respectively, when they were heading for their royal coronations to Kraków. December 16, 1740, was marked by the Prussian army entering the town during the first of the Silesian Wars; in 1742, Austrian domination ended and Tarnowskie Góry fell under Prussian rule. In 1742, after the end of Austrian rule, a Lutheran parish was established, whose first pastor was Polish religious writer and author of popular prayer-books Samuel Ludwik Zasadius. Around 1780 Friedrich Wilhelm von Reden opened a government-controlled mine as well as silver and lead foundry named "Frederyk" after Frederick William II, the king of Prussia. Jews, with a few exceptions, were restricted or altogether banned from the area throughout the years; yet still they managed to have a great impact on the entire region's progress. Salomon Isaac, Jewish trade-agent and mining entrepreneur, was one of the greatest contributors to the development of the Sillesian metallurgical and mining industries and, ultimately, become one of the managing officers of the newly formed Prussian Office of Mining in Tarnowskie Góry. Industrial Revolution In 1788, sparking the onset of the Industrial Revolution the first steam engine in continental Europe (and only the second one in the world) was imported from England and installed with a purpose of draining the underground waters. This was not a small task, miles of a deep adit or drainage-tunnel. A 600-metre part of former Fryderyk adit is a tourist route named Black Trout Adit. Its tunnels were cut through a solid bedrock and one of the system outlets, near Repty, became the main contributory of river Drama. Although Napoleonic Wars damaged and put a burden of heavy taxation on it, the town experienced another boom of growth and prosperity in the 19th century. In 1803 one of world's first schools of mining was initiated and,
