Once the strategic Schwerpunkt had been identified, the attack could commence, using the concept of Kesselschlacht (“cauldron battle”). A frontal attack would immobilize the enemy while forces on the flanks would execute a double envelopment, forming a pocket called a Kessel (“cauldron”) around the enemy. Once surrounded, the opposing army, demoralized and with no chance of escape, would face the choice of annihilation or surrender.

Historical accuracy is pushed to the edge as each unit is endowed with the actual capabilities and characteristics that existed at the time. Details such as the thickness of a tank's armor down to the range of infantry rifles add a level of previously unprecedented realism. Each campaign has been meticulously researched to provide an accurate depiction of the battles that took place, while still maintaining the flexibility (and fun!) necessary to let you play the way you want.

Birkenau had its first documentary mention in 795 in the Lorsch Codex as a cell of the Lorsch Abbey. As one of the Abbey’s holdings, it passed into the ownership of the Archbishopric of Mainz in 1232. The centres of Hornbach and Balzenbach, on the other hand, belonged to the Electorate of the Palatinate, meaning that after the Reformation, they belonged to different denominations. In 1532 the town hall was built, and in 1771 the palace, Schloss Birkenau, of the Lords of Wambolt von Umstadt. By 1964, the population had grown to more than 5,000. In 1967 the community was recognized as a recreational resort (Erholungsort) and in 1979 as an open-air resort (Luftkurort). Owing to the only slight tourism, however, it has not reapplied for this designation. In 1995, Birkenau celebrated its 1,200-year jubilee.
Defined by the religion of their grandparents rather than by their own beliefs, Jews were viewed as having impure blood lines. The new laws were taught in schools, cementing anti-Semitism in German culture. Most Germans kept quiet, often benefiting when Jews lost jobs and businesses. Persecution of other minorities also escalated: the police were given new powers to arrest homosexuals and compulsory abortions were administered to women considered to be ‘hereditarily ill’.
By July 1944, Germany was losing the war; the SS began closing down the easternmost concentration camps and deporting the remaining prisoners westward. Many were killed in Auschwitz and the Gross-Rosen concentration camp. Schindler convinced SS-Hauptsturmführer Amon Göth, commandant of the nearby Kraków-Płaszów concentration camp, to allow him to move his factory to Brněnec in the Protectorate of Bohemia and Moravia, thus sparing his workers from almost certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Göth's secretary Mietek Pemper compiled and typed the list of 1,200 Jews who travelled to Brünnlitz in October 1944. Schindler continued to bribe SS officials to prevent the execution of his workers until the end of World War II in Europe in May 1945, by which time he had spent his entire fortune on bribes and black market purchases of supplies for his workers.
