During the German
invasion of Poland in September 1939, Eicke's SS-TV field forces numbered four infantry regiments and a cavalry regiment, plus two battalions placed in
Free City of Danzig. The SS-TV role in the attack on Poland was not military in spite of close proximity to combat. "Their military capabilities were employed instead in terrorizing the civilian population through acts that included hunting down straggling Polish soldiers, confiscating agricultural produce and livestock, and torturing and murdering large numbers of Polish political leaders, aristocrats, businessmen, priests, intellectuals, and Jews." Eicke's three regiments, Oberbayern, Brandenburg and Thuringen, were reformed as the first
Einsatzgruppen; the Oberbayern and the Thuringen (EG II and EG z. B.V) followed the
Tenth Army in
Upper Silesia; the Brandenburg (EG III) followed the
Eight Army across
Warthegau. The behavior of these
Standarten in Poland elicited some protests from officers of the army, including 8th Army commander
Johannes Blaskowitz who wrote a memorandum to
Walther von Brauchitsch detailing the SS-TV atrocities, unaware that they were planned years in advance by the
Central Unit II P-Poland under
Heydrich who himself coordinated secret extermination actions including
Operation Tannenberg and the
Intelligenzaktion both targeting more than 61,000 members of Polish elites during the opening stages of
World War II. At the beginning of war in Europe, the SS forces consisted of roughly 250,000 servicemen spread out across multiple branches, with transferable ranks and service records from police regiments and the army. During the war, almost half of the concentration camp officers served with the
Waffen-SS combat divisions, including the
Leibstandarte,
Das Reich, Wiking, the Nord Division, and
Totenkopf. Some concentration camp officers served as division commanders in the
Waffen-SS. Within the camps themselves, there existed a hierarchy of camp titles and positions which were unique only to the camp service. Each camp was commanded by a
Kommandant, sometimes referred to as
Lagerkommandant, who was assisted by a camp adjutant and command staff. The prison barracks within the camp were supervised by a
Rapportführer who was responsible for daily roll call and the camp daily schedule. The individual prisoner barracks were overseen by junior SS-NCOs called
Blockführer who, in turn had one to two squads of SS soldiers responsible for overseeing the prisoners. Within the extermination camps, the
Blockführer was in charge of the prisoner
Sonderkommando and was also the person who would physically gas victims in the camp's gas chambers. The Jewish
Sonderkommando workers in turn, were terrorised by up to around 100 mostly collaborator
Trawniki men per camp, called
Wachmannschaften (security guards or watchmen). The camp perimeter and watch towers were overseen by a separate formation called the
Wachbattalion (guard battalion). The guard battalion commander was responsible for providing watch bills to man guard towers and oversaw security patrols outside the camp. The battalion was organized on typical military lines with companies, platoons, and squads. The battalion commander was subordinate directly to the camp commander. Concentration camps also had supply and medical personnel, attached to the headquarters office under the camp commander, as well as a security office with Gestapo and
Kripo personnel attached to the camp. Heydrich had been successful in getting control over the "political departments" of the camps. These security personnel were under direct command of
Sicherheitspolizei (SiPo) commanders until September 1939 and thereafter, the
Reich Security Main Office (
Reichssicherheitshauptamt, RSHA) commanders independent of the camps. In addition to the regular SS personnel assigned to a concentration camp, there also existed a prisoner system of trustees known as
Kapos who performed a wide variety of duties from administration to overseeing other groups of prisoners. The
Sonderkommandos were special groups of Jewish prisoners who assisted in the extermination camps with the disposal of bodies and other tasks. The duty of actually gassing prisoners was, however, always carried out by the SS. ==The Holocaust==
