beginning of the Thirty Years' War, the Prince-Provostry of Ellwangen, which still held the right of patronage in Aalen, were able to temporarily bring Catholicism back to Aalen; however after the military successes of the Protestant Union, Protestant church practices were instituted again. Fire of 1634 On the night of 5 September 1634, two ensigns of the army of Bernard of Saxe-Weimar who were fighting with the Swedes and retreating after the Battle of Nördlingen set fire to two powder carriages, to prevent the war material to fall into Croatian hands and to prevent their advance. The result was a conflagration, that some say destroyed portions of the town. There are differing stories regarding this fire. According to 17th-century accounts, the church and all the buildings, except of the Schwörturm tower, were casualties of the fire, and only nine families survived. 19th century research by Hermann Bauer, Lutheran pastor and local historian, discovered that the 17th-century account is exaggerated, but he does agree that the town church and buildings in a "rather large" semicircle around it were destroyed. The fire also destroyed the town archive housed in an addition to the church, with all of its documents. After the fire, soldiers of both armies went through the town looting. It took nearly 100 years for the town to reach its population of 2,000. French troops marched through Aalen in 1688 during the Nine Years' War; however, unlike other places, they left without leaving severe damages. The French came through again in 1702 during the War of the Spanish Succession and in 1741 during the War of the Austrian Succession, the latter also caused imperial troops to move through in 1743. The town church's tower collapsed in 1765, presumably because proper building techniques were not utilized during the reconstruction after the fire of 1634. The collapsing tower struck two children of the tower watchman who died of their injuries, and destroyed the nave, leaving only the altar cross intact. The remaining walls had to be knocked down due to the damage. Reconstruction began the same year, creating the building that exists today. On 22 November 1749, the so-called Aalen protocol regulating the cohabitation of Lutherans and Roman Catholics in the jointly ruled territory of Oberkochen was signed in Aalen by the Duchy of Württemberg and the Prince-Provostry of Ellwangen. Aalen had been chosen because of its neutral status as a Free
