What year did Heinrich Himmler join the unit that used the concept of Wehrbauer to refer to soldiers designated as settlers for the lands conquered during the German invasions of the Soviet Union and Poland?
Schutzstaffel The Schutzstaffel (SS; also stylized as with Armanen runes; ] ; literally "Protection Squadron") was a major paramilitary organization under Adolf Hitler and the Nazi Party (NSDAP) in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the "Saal-Schutz" (Hall-Protection) made up of NSDAP volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–45), it grew from a small paramilitary formation to one of the most powerful organizations in Nazi Germany. From 1929 until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe.
Battle of Jaworów The Battle of Jaworów (Polish: "bitwa pod Jaworowem" ) was a battle fought between the German forces and elements of the Polish Małopolska Army during the German Invasion of Poland. It took place from 14 to 16 September 1939 in the vicinity of the town of Jaworów. In the effect of a two-day assault, the Polish forces broke through the German line of defence on their way towards the city of Lwów (modern Lviv). The engagement is best known for the destruction of one battalion of three battalions of SS-Germania regiment together with the capture of the heavy equipment of the entire regiment.
