In general, subcamps that produced or processed agricultural goods were administratively subordinate to Auschwitz-Birkenau. Subcamps whose prisoners were deployed at industrial and armaments production or in extractive industries (e.g., coal mining, quarry work) were administratively subordinate to Auschwitz-Monowitz. This division of administrative responsibility was formalized after November 1943.
After the Allied landings at Normandy, Germany made attempts to overwhelm the landing force with armored attacks, but these failed for lack of co-ordination and Allied air superiority. The most notable attempt to use deep penetration operations in Normandy was at Mortain, which exacerbated the German position in the already-forming Falaise Pocket and assisted in the ultimate destruction of German forces in Normandy. The Mortain counter-attack was effectively destroyed by U.S. 12th Army Group with little effect on its own offensive operations.
The Jews killed represented around one third of the world population of Jews,[398] and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war.[399] Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.[392]
At the end of the war, in an effort to remove the traces of the crimes they had committed, the SS began dismantling and razing the gas chambers, crematoria, and other buildings, as well as burning documents. Prisoners capable of marching were evacuated into the depths of the German Reich, and thousands of marchers died of hunger, exhaustion and exposure. Those who remained behind in the camp and survived long enough were liberated by Red Army soldiers on 27 January 1945.
A Jewish skeleton collection was obtained from among a pool of 115 Jewish Auschwitz inmates, chosen for their perceived stereotypical racial characteristics.[b] Rudolf Brandt and Wolfram Sievers, general manager of the Ahnenerbe (a Nazi research institute), delivered the skeletons to the collection of the Anatomy Institute at the Reichsuniversität Straßburg in Occupied France. The collection was sanctioned by Himmler and under the direction of August Hirt. Ultimately 87 of the inmates were shipped to Natzweiler-Struthof and killed in August 1943.[135] Brandt and Sievers were executed in 1948 after being convicted during the Doctors' trial, part of the Subsequent Nuremberg trials.[citation needed]
On 31 July 1941, Hermann Göring gave written authorization to Reinhard Heydrich, Chief of the Reich Security Head Office (RSHA), to prepare and submit a plan for Die Endlösung der Judenfrage (the Final Solution of the Jewish question) in territories under German control and to coordinate the participation of all involved government organizations.[152] Plans for the extermination of the European Jews—eleven million people—were formalized at the Wannsee Conference in Berlin on 20 January 1942. Some would be worked to death and the rest killed.[153] Initially the victims were killed with gas vans or by Einsatzgruppen firing squads, but these methods were impractical for an operation of this scale.[154] By 1942, killing centers at Auschwitz, Sobibór, Treblinka, and other extermination camps had become the primary method of mass killing.[155]
Deportees were brought to Auschwitz crammed in wretched conditions into goods or cattle wagons, arriving near a railway station or at one of several dedicated trackside ramps, including one next to Auschwitz I. The Altejudenrampe (old Jewish ramp), part of the Oświęcim freight railway station, was used from 1942 to 1944 for Jewish transports.[102][103] Located between Auschwitz I and Auschwitz II, arriving at this ramp meant a 2.5 km journey to Auschwitz II and the gas chambers. Most deportees were forced to walk, accompanied by SS men and a car with a Red Cross symbol that carried the Zyklon B, as well as an SS doctor in case officers were poisoned by mistake. Inmates arriving at night, or who were too weak to walk, were taken by truck.[104] Work on another railway line and Judenrampe (pictured right) between sectors BI and BII in Auschwitz II, was completed in May 1944 for the arrival of Hungarian Jews,[103] who between May and early July 1944 were deported to Auschwitz II at a rate of 12,000 a day.[105] The rails led directly to the area around the gas chambers.[102]
On January 30, 1933, Adolf Hitler, leader of the National Socialist German Workers (Nazi) Party, was named chancellor of Germany by President Paul von Hindenburg after the Nazi party won a significant percentage of the vote in the elections of 1932. The Nazi Party had taken advantage of the political unrest in Germany to gain an electoral foothold. The Nazis incited clashes with the communists and conducted a vicious propaganda campaign against its political opponents - the weak Weimar government and the Jews whom the Nazis blamed for Germany's ills.
After the start of World War II, Adolf Hitler (1889-1945), the chancellor of Germany from 1933 to 1945, implemented a policy that came to be known as the “Final Solution.” Hitler was determined not just to isolate Jews in Germany and countries annexed by the Nazis, subjecting them to dehumanizing regulations and random acts of violence. Instead, he became convinced that his “Jewish problem” would be solved only with the elimination of every Jew in his domain, along with artists, educators, Gypsies, communists, homosexuals, the mentally and physically handicapped and others deemed unfit for survival in Nazi Germany.
Half of the German divisions available in 1940 were combat ready but less well-equipped than the British and French or the Imperial German Army of 1914. In the spring of 1940, the German army was semi-modern, in which a small number of well-equipped and "elite" divisions were offset by many second and third rate divisions".[135] In 2003, John Mosier wrote that while the French soldiers in 1940 were better trained than German soldiers, as were the Americans later and that the German army was the least mechanised of the major armies, its leadership cadres were larger and better and that the high standard of leadership was the main reason for the successes of the German army in World War II, as it had been in World War I.[136]
Blitzkrieg's widest influence was within the Western Allied leadership of the war, some of whom drew inspiration from the Wehrmacht's approach. United States General George S. Patton emphasized fast pursuit, the use of an armored spearhead to effect a breakthrough, then cut off and disrupt enemy forces prior to their flight. In his comments of the time, he credited Guderian and Rommel's work, notably Infantry Attacks, for this insight. He also put into practice the idea attributed to cavalry leader Nathan Bedford Forrest, "Get there fastest with the mostest." (Get there fastest, with the most forces).
Although effective in quick campaigns against Poland and France, mobile operations could not be sustained by Germany in later years. Strategies based on manoeuvre have the inherent danger of the attacking force overextending its supply lines, and can be defeated by a determined foe who is willing and able to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front (as opposed to, for example, the Dutch who had no territory to sacrifice). Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks.[75] As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing and blockade. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.[76]

The Reichswehr and Red Army collaborated in wargames and tests in Kazan and Lipetsk beginning in 1926. During this period, the Red Army was developing the theory of Deep operations, which would guide Red Army doctrine throughout World War II. Set within the Soviet Union, these two centers were used to field test aircraft and armored vehicles up to the battalion level, as well as housing aerial and armored warfare schools through which officers were rotated. This was done in the Soviet Union, in secret, to evade the Treaty of Versailles's occupational agent, the Inter-Allied Commission.
After Germany's failure to destroy the Soviets before the winter of 1941, the limits of German tactical superiority became apparent. Although the German invasion successfully conquered large areas of Soviet territory, the overall strategic effects were more limited. The Red Army was able to regroup far to the rear of the main battle line, and eventually defeat the German forces for the first time in the Battle of Moscow.
Throughout the Middle Ages in Europe, Jews were subjected to antisemitism based on Christian theology, which blamed them for killing Jesus. Even after the Reformation, Catholicism and Lutheranism continued to persecute Jews, accusing them of blood libels and subjecting them to pogroms and expulsions.[60][61] The second half of the 19th century saw the emergence in the German empire and Austria-Hungary of the völkisch movement, which was developed by such thinkers as Houston Stewart Chamberlain and Paul de Lagarde. The movement embraced a pseudo-scientific racism that viewed Jews as a race whose members were locked in mortal combat with the Aryan race for world domination.[62] These ideas became commonplace throughout Germany,[63] with the professional classes adopting an ideology that did not see humans as racial equals with equal hereditary value.[64] Although the völkisch parties had support in elections at first, by 1914 they were no longer influential. This did not mean that antisemitism had disappeared; instead it was incorporated into the platforms of several mainstream political parties.[63]
I'm 15 years old, and visited Auschwitz and Auschwitz Birkenau about a month ago on a school trip. It was an incredibly moving experience, and something I think everyone should visit at least once i their life. I know for sure that one day I will take my children and even grandchildren, as it is just so important for future generations to learn as much as they can about what happened so that we can be sure it will never, ever happen again.
The history of Auschwitz-Birkenau as an extermination center is complex. From late 1941 to October 1942, the mortuary at Auschwitz main camp, which was already equipped with a crematorium, was adapted as a gas chamber. It measured approximately 835 square feet. In the spring of 1942, two provisional gas chambers at Birkenau were constructed out of peasant huts, known as the 'bunkers'.
[t]hroughout the Polish Campaign, the employment of the mechanised units revealed the idea that they were intended solely to ease the advance and to support the activities of the infantry....Thus, any strategic exploitation of the armoured idea was still-born. The paralysis of command and the breakdown of morale were not made the ultimate aim of the ... German ground and air forces, and were only incidental by-products of the traditional maneuvers of rapid encirclement and of the supporting activities of the flying artillery of the Luftwaffe, both of which had as their purpose the physical destruction of the enemy troops. Such was the Vernichtungsgedanke of the Polish campaign.[82]

Tours provided by the museum in various languages cost 40 zł (discounted price for students up to 24 years of age is 30 zł) and are recommended if you want a deeper understanding of the site, but they are unfortunately somewhat rushed, and you can get a pretty good feel by buying a guidebook and map (small simple guide costs 5 zł) and wandering around on your own.
Upon arrival in Gliwice and Wodzislaw, the prisoners were put on unheated freight trains and transported to concentration camps in Germany, particularly to Flossenbürg, Sachsenhausen, Gross-Rosen, Buchenwald, Dachau, and also to Mauthausen in Austria. The rail journey lasted for days. Without food, water, shelter, or blankets, many prisoners did not survive the transport.

Methods of mass murder evolved at local levels as well as being decreed from Nazi high command. Killing squads rounded up and shot entire Jewish communities. Over two days in Kiev, 33,771 Jews were shot. The murder of Jews rapidly escalated, in part because local Nazi leaders didn’t have enough room to place them in the ghettos. By the end of the year, plans to implement the systematic slaughter of Jews by using gas in mobile trucks and gas chambers were well underway.

Known as block 13 until 1941, block 11 of Auschwitz I was the prison within the prison, where violators of the numerous rules were punished. To extract information from them, guards would hold inmates' heads held against the stove, burning their faces and eyes. Some prisoners were made to spend the nights in standing cells. Measuring 1.5 m2 (16 sq ft), the cells held four men who could do nothing but stand, and who were forced the following day to work as usual.[136] In other cells, inmates were subjected to hanging with their hands behind their backs, thus dislocating their shoulder joints. In the basement were the "dark cells", which had only a 5 x 5 cm opening and a solid door. Prisoners placed in these cells gradually suffocated as they ran out of oxygen; sometimes the SS lit a candle in the cell to use up the oxygen more quickly.[137]
In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).

Miconic 10 was introduced in 1996, and was the industry first of an innovative type of control systems now known as hall call destination system. The system features keypads and LED screens instead of hall button stations whereby riders enter their desired floor before entering an elevator car. The system then directs the rider to a specific elevator car while grouping riders traveling to nearby floors together. Schindler claims this minimizes the number of stops, and decreases congestion and travel time—especially during peak traffic periods. The system was continuously further developed and new functions were amended eventually evolving in systems which guarantee highly efficient and energy saving traffic management. Especially in high rise buildings traffic management systems like Miconic 10 and Schindler ID allow building designers to maximize rentable space and transport efficiency. Moreover, access control becomes feasible.
Beginning with the British air raids on Cologne in May of 1942, the Allies launched a strategic bombing campaign that would target cities and industrial plants across the Reich for the next three years. In the summer of 1942, Germany and its allies focused on the Soviet Union unsuccessfully. The Soviet Union gained the dominant role, which it would maintain for the rest of the war.
In English and other languages, the term had been used since the 1920s.[4] The British press used it to describe the German successes in Poland in September 1939, called by Harris "a piece of journalistic sensationalism – a buzz-word with which to label the spectacular early successes of the Germans in the Second World War". It was later applied to the bombing of Britain, particularly London, hence "The Blitz".[22] The German popular press followed suit nine months later, after the fall of France in 1940; hence although the word had been used in German, it was first popularized by British journalism.[5][8] Heinz Guderian referred to it as a word coined by the Allies: "as a result of the successes of our rapid campaigns our enemies ... coined the word Blitzkrieg".[23] After the German failure in the Soviet Union in 1941, use of the term began to be frowned upon in the Third Reich, and Hitler then denied ever using the term, saying in a speech in November 1941, "I have never used the word Blitzkrieg, because it is a very silly word".[24] In early January 1942, Hitler dismissed it as "Italian phraseology".[25][26]

Auschwitz I, a former Polish army barracks, was the main camp (Stammlager) and administrative headquarters of the camp complex. Intending to use it to house political prisoners, Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), approved the site in April 1940 on the recommendation of SS-Obersturmbannführer (lieutenant colonel) Rudolf Höss, then of the Concentration Camps Inspectorate. Höss oversaw the development of the camp and served as its first commandant, with SS-Obersturmführer (senior lieutenant) Josef Kramer as his deputy.[21] Around 1,000 m long and 400 m wide,[22] Auschwitz I consisted of 20 brick buildings, six of them two-story; a second story was added to the others in 1943 and eight new blocks were built.[23] The camp housed the SS barracks and by 1943 held 30,000 inmates.[22] The first 30 prisoners arrived on 20 May 1940 after being transported from the Sachsenhausen concentration camp in Oranienburg, Germany. Convicted German criminals (Berufsverbrecher), the men were known as "greens" after the green triangles they were required to wear on their prison clothing. Brought to the camp as functionaries, this group did much to establish the sadism of early camp life, which was directed particularly at Polish inmates, until the political prisoners began to take over their roles.[4]
Fewer than 200 Jews escaped from the camps. Herman Shine, one of the last survivors to have escaped Auschwitz, died in July 2018. He was born in Berlin to a Polish father and they were arrested in that city in 1939. Along with 1,700 other Polish Jews, they were deported to Sachsenhausen. To survive, Shine claimed to be a roofer and learned how to build roofs before being transferred to Auschwitz in 1942.
Auschwitz inmates began working at the plant, known as Buna Werke and IG Auschwitz, in April 1941, and demolishing houses in Monowitz to make way for it. By May, because of a shortage of trucks, several hundred of them were rising at 3 am to walk there twice a day from Auschwitz I.[53] Anticipating that a long line of exhausted inmates walking through the town of Oświęcim might harm German-Polish relations, the inmates were told to shave daily, make sure they were clean, and sing as they walked. From late July they were taken there by train on freight wagons.[54] Because of the difficulty of moving them, including during the winter, IG Farben decided to build a camp at the plant. The first inmates moved there on 30 October 1942.[55] Known as KL Auschwitz III-Aussenlager (Auschwitz III-subcamps), and later as Monowitz concentration camp,[56] it was the first concentration camp to be financed and built by private industry.[57]
The German offensive to capture Stalingrad began in August 1942, using the 6th Army and elements of the 4th Panzer Army. The attack was supported by intensive Luftwaffe bombing that reduced much of the city to rubble. The fighting degenerated into house-to-house fighting; both sides poured reinforcements into the city. By mid-November 1942, the Germans had pushed the Soviet defenders back at great cost into narrow zones along the west bank of the Volga River.
On the war's Eastern Front, combat did not bog down into trench warfare. German and Russian armies fought a war of maneuver over thousands of miles, giving the German leadership unique experience which the trench-bound Western Allies did not have. Studies of operations in the East led to the conclusion that small and coordinated forces possessed more combat worth than large, uncoordinated forces.

Blitzkrieg's immediate development began with Germany's defeat in the First World War. Shortly after the war, the new Reichswehr created committees of veteran officers to evaluate 57 issues of the war. The reports of these committees formed doctrinal and training publications which were the standards in the Second World War. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular its infiltration tactics of the war, and the maneuver warfare which dominated the Eastern Front.
Auschwitz-Birkenau was the largest Nazi extermination and concentration camp, located in the Polish town of Oswiecim, 37 miles west of Cracow. One sixth of all Jews murdered by the Nazis were gassed at Auschwitz. In April 1940 SS chief Heinrich Himmler ordered the establishment of a new concentration camp in Oswiecim, a town located within the portion of Poland that was annexed to Germany at the beginning of World War II. The first Polish political prisoners arrived in Auschwitz in June 1940, and by March 1941 there were 10,900 prisoners, the majority of whom were Polish. Auschwitz soon became known as the most brutal of the Nazi concentration camps.
By mid-1944 those Jewish communities within easy reach of the Nazi regime had been largely exterminated,[367] in proportions ranging from about 25 percent in France[368] to more than 90 percent in Poland.[369] On 5 May Himmler claimed in a speech that "the Jewish question has in general been solved in Germany and in the countries occupied by Germany".[370] As the Soviet armed forces advanced, the camps in eastern Poland were closed down, with surviving inmates shipped to camps closer to Germany.[371] Efforts were made to conceal evidence of what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and the corpses cremated.[372] Local commanders continued to kill Jews, and to shuttle them from camp to camp by forced "death marches".[373] Already sick after months or years of violence and starvation, some were marched to train stations and transported for days at a time without food or shelter in open freight cars, then forced to march again at the other end to the new camp. Others were marched the entire distance to the new camp. Those who lagged behind or fell were shot. Around 250,000 Jews died during these marches.[374]
By the late 1930s there was a desperate search for countries of refuge. Those who could obtain visas and qualify under stringent quotas emigrated to the United States. Many went to Palestine, where the small Jewish community was willing to receive refugees. Still others sought refuge in neighbouring European countries. Most countries, however, were unwilling to receive large numbers of refugees.
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.

Guderain recognised the importance of tanks  © This doctrine integrated the operational-level ideas taught by Schlieffen with the tactical concepts developed during World War One. And as military technology, including that of tanks, motor vehicles, aircraft and radios, was developed during the 1920s and 30s, so it was grafted onto this doctrinal framework.
Soon after he became chancellor, Hitler called for new elections in an effort to get full control of the Reichstag, the German parliament, for the Nazis. The Nazis used the government apparatus to terrorize the other parties. They arrested their leaders and banned their political meetings. Then, in the midst of the election campaign, on February 27, 1933, the Reichstag building burned. A Dutchman named Marinus van der Lubbe was arrested for the crime, and he swore he had acted alone. Although many suspected the Nazis were ultimately responsible for the act, the Nazis managed to blame the Communists, thus turning more votes their way.

After the Allied landings at Normandy, Germany made attempts to overwhelm the landing force with armored attacks, but these failed for lack of co-ordination and Allied air superiority. The most notable attempt to use deep penetration operations in Normandy was at Mortain, which exacerbated the German position in the already-forming Falaise Pocket and assisted in the ultimate destruction of German forces in Normandy. The Mortain counter-attack was effectively destroyed by U.S. 12th Army Group with little effect on its own offensive operations.
Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.
At this time only the main camp, later known as Auschwitz I, had been established. Himmler ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka, roughly two miles from the main camp. This second camp, now known as Birkenau or Auschwitz II, was initially intended to be filled with captured Russian POWs who would provide the slave labor to build the SS “utopia” in Upper Silesia. Chemical giant I G Farben expressed an interest in utilizing this labor force, and extensive construction work began in October 1941 under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in this process. The greater part of the apparatus of mass extermination was eventually built in the Birkenau camp and the majority of the victims were murdered here.

Around one in six Jews killed in the Holocaust died in Auschwitz.[195] By nation, the greatest number of Auschwitz's Jewish victims originated from Hungary, accounting for 430,000 deaths, followed by Poland (300,000), France (69,000), Netherlands (60,000), Greece (55,000), Protectorate of Bohemia and Moravia (46,000), other camps (34,000), Slovakia (27,000), Belgium (25,000), Germany and Austria (23,000), Yugoslavia (10,000), Italy (7,500), and Norway (690).[6] Fewer than one percent of Soviet Jews murdered in the Holocaust were killed in Auschwitz; German forces had already been driven from Russia when the killing at Auschwitz reached its peak in 1944.[196] Of the 400 Jehovah's Witnesses who were imprisoned at Auschwitz, 132 died there.[197]
German operational theories were revised after the First World War. The Treaty of Versailles limited the Reichswehr to a maximum of 100,000 men, making impossible the deployment of mass armies. The German General Staff was abolished by the treaty but continued covertly as the Truppenamt (Troop Office), disguised as an administrative body. Committees of veteran staff officers were formed within the Truppenamt to evaluate 57 issues of the war.[29] By the time of the Second World War, their reports had led to doctrinal and training publications, including H. Dv. 487, Führung und Gefecht der verbundenen Waffen (Command and Battle of the Combined Arms), known as das Fug (1921–23) and Truppenführung (1933–34), containing standard procedures for combined-arms warfare. The Reichswehr was influenced by its analysis of pre-war German military thought, in particular infiltration tactics, which at the end of the war had seen some breakthroughs on the Western Front and the manoeuvre warfare which dominated the Eastern Front.
In the spring of 1941, German conglomerate I.G. Farben established a factory in which its executives intended to exploit concentration camp labor to manufacture synthetic rubber and fuels. I.G. Farben invested more than 700 million Reichsmarks (about 2.8 million US dollars in 1941 terms) in Auschwitz III. From May 1941 until July 1942, the SS had transported prisoners from Auschwitz I to the “Buna Detachment,” at first on foot and later by rail. (Between July and October 1942 there was a pause in transports, due to a typhus epidemic and quarantine.) With the construction of Auschwitz III in the autumn of 1942, prisoners deployed at Buna lived in Auschwitz III.
In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.

The chief of construction of Auschwitz II-Birkenau was Karl Bischoff, a competent and dynamic bureaucrat who, in spite of the ongoing war, carried out the construction deemed necessary. The Birkenau camp, the four crematoria, a new reception building, and hundreds of other buildings were planned and constructed.[42] Bischoff's plans, based on an initial budget of RM 8.9 million, called for each barracks to hold 550 prisoners. He later changed this to 744 per barracks, which meant the camp could hold 125,000, rather than 97,000.[43] The SS designed the barracks not so much to house people as to destroy them.[42] There were 174 barracks, each measuring 116 by 36 ft, divided into 62 bays of 43 sq. ft. The bays were divided into "roosts", initially for three inmates and later for four. With personal space of 11 sq. ft to sleep and place whatever belongings they had, inmates were deprived, Robert-Jan van Pelt wrote, "of the minimum space needed to exist".[44]

Shipments of Jews to the camps had priority over anything but the army's needs on the German railways, and continued even in the face of the increasingly dire military situation at the end of 1942.[355] Army leaders and economic managers complained about this diversion of resources and the killing of skilled Jewish workers,[356] but Nazi leaders rated ideological imperatives above economic considerations.[357]
German volunteers first used armour in live field conditions during the Spanish Civil War of 1936. Armour commitment consisted of Panzer Battalion 88, a force built around three companies of Panzer I tanks that functioned as a training cadre for Nationalists. The Luftwaffe deployed squadrons of fighters, dive bombers and transport aircraft as the Condor Legion.[77] Guderian said that the tank deployment was "on too small a scale to allow accurate assessments to be made."[78] The true test of his "armoured idea" would have to wait for the Second World War. However, the Luftwaffe also provided volunteers to Spain to test both tactics and aircraft in combat, including the first combat use of the Stuka.[79]

Guderian believed that developments in technology were required to support the theory; especially, equipping armoured divisions—tanks foremost–with wireless communications. Guderian insisted in 1933 to the high command that every tank in the German armoured force must be equipped with a radio.[54] At the start of World War II, only the German army was thus prepared with all tanks "radio-equipped". This proved critical in early tank battles where German tank commanders exploited the organizational advantage over the Allies that radio communication gave them. Later all Allied armies would copy this innovation. During the Polish campaign, the performance of armoured troops, under the influence of Guderian's ideas, won over a number of skeptics who had initially expressed doubt about armoured warfare, such as von Rundstedt and Rommel.[55]
