On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed. On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."
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. 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. 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, who between May and early July 1944 were deported to Auschwitz II at a rate of 12,000 a day. The rails led directly to the area around the gas chambers.
Various other German industrial enterprises, such as Krupp and Siemens-Schuckert, built factories with their own subcamps. There were around 40 or 50 such camps, 28 of them near industrial plants, each camp holding hundreds or thousands of prisoners. Designated as Aussenlager (external camp), Nebenlager (extension or subcamp), or Arbeitslager (labor camp), camps were built at Blechhammer, Jawiszowice, Jaworzno, Lagisze, Mysłowice, Trzebinia, and centers as far afield as the Protectorate of Bohemia and Moravia in Czechoslovakia. Industries with satellite camps included coal mines, foundries and other metal works, and chemical plants. Prisoners were also made to work in forestry and farming. Budy, for example, was a farming subcamp where prisoners worked 12-hour days, often in the fields, but sometimes tending animals, cleaning ponds, digging ditches, and making compost. Human ashes from the crematorium were mixed with sod and manure to make the compost. Incidents of sabotage to decrease production took place in several subcamps, including Charlottengrube, Gleiwitz II, and Rajsko.
Later manifestations of blitzkrieg tactics were the combined air and ground attacks by Israeli forces on Syria and Egypt during the Six-Day War (June 1967) and the Israeli counterattacks and final counteroffensive of the Yom Kippur War (October 1973). The “left hook” flanking maneuver executed by U.S. Gen. Norman Schwarzkopf during the Persian Gulf War also utilized elements of blitzkrieg tactics, with a combined arms offensive that destroyed the Iraqi army in Kuwait in a period of just three days.
The superior race was the "Aryans," the Germans. The word Aryan, "derived from the study of linguistics, which started in the eighteenth century and at some point determined that the Indo-Germanic (also known as Aryan) languages were superior in their structures, variety, and vocabulary to the Semitic languages that had evolved in the Near East. This judgment led to a certain conjecture about the character of the peoples who spoke these languages; the conclusion was that the 'Aryan' peoples were likewise superior to the 'Semitic' ones" (Leni Yahil, The Holocaust: The Fate of European Jewry, New York: Oxford University Press, 1990, p. 36).
On October 7, 1944, several hundred prisoners assigned to Crematorium IV at Auschwitz-Birkenau rebelled after learning that they were going to be killed. During the uprising, the prisoners killed three guards and blew up the crematorium and adjacent gas chamber. The prisoners used explosives smuggled into the camp by Jewish women who had been assigned to forced labor in a nearby armaments factory.
The generally accepted definition of blitzkrieg operations include the use of maneuver rather than attrition to defeat an opponent, and describe operations using combined arms concentration of mobile assets at a focal point, armour closely supported by mobile infantry, artillery and close air support assets. These tactics required the development of specialized support vehicles, new methods of communication, new tactics, and an effective decentralized command structure. Broadly speaking, blitzkrieg operations required the development of mechanized infantry, self-propelled artillery and engineering assets that could maintain the rate of advance of the tanks. German forces avoided direct combat in favour of interrupting an enemy's communications, decision-making, logistics and of reducing morale. In combat, blitzkrieg left little choice for the slower defending forces but to clump into defensive pockets that were encircled and then destroyed by following German infantry.
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.
John Ellis wrote that "...there is considerable justice in Matthew Cooper's assertion that the panzer divisions were not given the kind of strategic mission that was to characterize authentic armoured blitzkrieg, and were almost always closely subordinated to the various mass infantry armies." Steven Zaloga wrote, "Whilst Western accounts of the September campaign have stressed the shock value of the panzer and Stuka attacks, they have tended to underestimate the punishing effect of German artillery on Polish units. Mobile and available in significant quantity, artillery shattered as many units as any other branch of the Wehrmacht."
Schindler started out as a wartime profiteer, having acquired an enamelware factory in Poland in 1939. At the height of his business, Schindler had 1,750 workers under his employment — 1000 of them Jewish. Over time, his daily interactions with his Jewish workers prompted him to use his political connections as a former German spy and his wealth to bribe Nazi officers to prevent his workers from being deported and killed. Through various Jewish administrators came what was known as "Schindler's List," although in reality, there were nine separate lists and Schindler, at the time, did not oversee the details since he was incarcerated for suspicion of bribery.
Medical experiments conducted on camp inmates by the SS were another distinctive feature. At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later. Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers. Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.
In April 1940, Rudolph Höss, who become the first commandant, identified the Silesian town of Oswiecim as a possible site for a concentration camp. The function of the camp was initially to intimidate Poles and prevent resistance to German rule. It was also perceived as a cornerstone of the policy to re-colonize Upper Silesia, which had once been a German region, with 'pure Aryans'. On April 27th, Himmler ordered construction of the camp.
In the German parliament, the Nazi party, led by Adolf Hitler, gained popularity. The number of seats Nazis controlled in the parliament rose from 12 in 1928 to 230 in 1932, making them the largest political party. The strong showing guaranteed the Nazi party would need to be part of any political coalition. Believing he could check Hitler’s ambition, President Hindenburg reluctantly made Hitler the Chancellor of Germany on January 30, 1933.
SS officers, including the infamous Dr. Josef Mengele, would conduct selections among these lines, sending most victims to one side and thus condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria. Those not sent to the gas chambers were taken to “quarantine,” where their hair was shaved, striped prison uniforms distributed, and registration took place. Prisoners’ individual registration numbers were tattooed onto their left arm.
After WWII had ended, photographs of the Holocaust stunned the public. Newspapers in the United States had reported on the oppression of the Jews in Germany during the war. In 1942, many newspapers were writing details of the Holocaust, but these stories were short and were not widely read. In 1943, after sources had confirmed the killings of at least two million Jews in concentration camps across Europe a Gallup poll found that less than half of Americans believed these reports to be true; 28% thought they were “just a rumor”. The reports were unconfirmed and sometimes denied by the United States government.
British theorists J.F.C. Fuller and Captain B. H. Liddell Hart have often been associated with blitzkrieg's development, though this is a matter of controversy. The British War Office did permit an Experimental Mechanised Force, formed on 1 May 1927, that was wholly motorized including self propelled artillery and motorised engineers. It is argued that Guderian, a critical figure in blitzkrieg's conception, drew some of his inspiration from Liddell Hart. This was based on a paragraph in the English edition of Guderian's autobiography in which he credits Liddell Hart. In opposition, it is argued that Liddell Hart, as editor of the autobiography's English edition, wrote that paragraph himself or, more broadly, that his influence on Guderian was not as significant as held. Fuller's influence is less clear. During the war, he developed plans for massive, independent tank operations and was subsequently studied by the German leadership. It is variously argued that Fuller's wartime plans and post-war writings were an inspiration, or that his readership was low and German experiences during the war received more attention.
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. Guderian said that the tank deployment was "on too small a scale to allow accurate assessments to be made." 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.
Blitzkrieg tactics were used in the successful German invasions of Belgium, the Netherlands, and France in 1940, which saw audacious applications of air power and airborne infantry to overcome fixed fortifications that were believed by the defenders to be impregnable. The Kesselschlacht campaigns on the Eastern Front were staggering in scale, with Kessels that covered vast swathes of territory, enveloping hundreds of thousands of troops. Blitzkrieg tactics were also used by the German commander Erwin Rommel during the desert campaigns in North Africa.
The Nazis regarded the Slavs as subhuman, or Untermenschen. In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[y] In November 1939 German planners called for "the complete destruction" of all Poles and resettlement of the land by German colonists. The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion). Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians. At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed. During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene. The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war. Around 6 million of World War II victims were Polish citizens; half the death toll were Jews. Over the course of the war Poland lost 20 percent of its pre-war population. Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union. Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.
Inmates at Birkenau numbered around 100,000 at their peak. They were of many different nationalities, but the vast majority of those that entered the camp were unregistered Jews, many of whom were immediately sent to their deaths in the gas chambers. Women and children stood the least chance of survival, and many died even before arriving at Birkenau due to the appalling conditions of the railway journeys. The unloading platform, where the brisk selection process was conducted, remains. Apart from physically fit men (who often perished later from the rigours of the camp) it was often only an accident of birth that merited a possibility of survival. Large numbers of twins survived until liberation as they were objects of interest to the research of Dr. Josef Mengele - a man disliked even by his Nazi peers.
Ultimately, three SS guards were killed—one of whom was burned alive by the prisoners in the oven of Crematorium II—and 451 Sonderkommandos were killed. Hundreds of prisoners escaped, but all were soon captured and executed, along with an additional group who had participated in the revolt. Crematorium IV was destroyed in the fighting. A group of prisoners in the gas chamber of Crematorium V was spared in the chaos.
Blitzkrieg is simply a swiftly executed encirclement that presents an enemy force with an unenviable choice: annihilation or surrender. The name conveys the speed, the force and the effect of the attack. It builds on a few innovations that the Germans borrowed from the best military thinkers of the time, which they then packed into a coherent, comprehensive tactic:
Blitzkrieg was based on speed, co-ordination and movement; the major science of this approach was the ability to get large mobile forces through weak points in the enemies defences and then cause damage when behind his static lines. With large formations cut off from communication and logistics, pressure could then be put on interior defences. Its aim was to create panic amongst the civilian population. A civil population on the move can be absolute havoc for a defending army trying to get its forces to the war front. With so much focus placed on the frontline, if this could be penetrated then the ensuing doubt, confusion and rumour were sure to paralyse both the government and the defending military.
In 1916, General Alexei Brusilov had used surprise and infiltration tactics during the Brusilov Offensive. Later, Marshal Mikhail Tukhachevsky, Georgii Isserson and other members of the Red Army developed a concept of deep battle from the experience of the Polish–Soviet War. These concepts would guide Red Army doctrine throughout World War II. Realising the limitations of infantry and cavalry, Tukhachevsky was an advocate of mechanised formations and the large-scale industrialisation required. Robert Watt (2008) wrote that blitzkrieg holds little in common with Soviet deep battle. In 2002, H. P. Willmott had noted that deep battle contained two important differences: it was a doctrine of total war, not limited operations, and decisive battle was rejected in favour of several large, simultaneous offensives.
The Germans' overwhelming repression and the presence of many collaborators in the various local populations severely limited the ability of the Jews to resist. Jewish resistance did occur, however, in several forms. Staying alive, clean, and observing Jewish religious traditions constituted resistance under the dehumanizing conditions imposed by the Nazis. Other forms of resistance involved escape attempts from the ghettos and camps. Many who succeeded in escaping the ghettos lived in the forests and mountains in family camps and in fighting partisan units. Once free, though, the Jews had to contend with local residents and partisan groups who were often openly hostile. Jews also staged armed revolts in the ghettos of Vilna, Bialystok, Bedzin-Sosnowiec, krakow, and Warsaw.
Nazi racial policy aimed at forcing Jews to emigrate. Fifty thousand German Jews had left Germany by the end of 1934, and by the end of 1938, approximately half the German Jewish population had left the country. Among the prominent Jews who left was the conductor Bruno Walter, who fled after being told that the hall of the Berlin Philharmonic would be burned down if he conducted a concert there. Albert Einstein, who was in the United States when Hitler came to power, never returned to Germany; he was expelled from the Kaiser Wilhelm Society and the Prussian Academy of Sciences and his citizenship was revoked. Other Jewish scientists, including Gustav Hertz, lost their teaching positions and left the country. On 12 March 1938, Germany annexed Austria. Austrian Nazis broke into Jewish shops, stole from Jewish homes and businesses, and forced Jews to perform humiliating acts such as scrubbing the streets or cleaning toilets. Jewish businesses were "Aryanized", and all the legal restrictions on Jews in Germany were imposed. In August that year, Adolf Eichmann was put in charge of the Central Agency for Jewish Emigration in Vienna (Zentralstelle für jüdische Auswanderung in Wien). About 100,000 Austrian Jews had left the country by May 1939, including Sigmund Freud and his family, who moved to London. The Évian Conference was held in July 1938 by 32 countries as an attempt to help the increased refugees from Germany, but aside from establishing the largely ineffectual Intergovernmental Committee on Refugees, little was accomplished and most countries participating did not increase the number of refugees they would accept.
After their defeat in 1918, German military intellectuals began reshaping the army. Under the direction of Hans von Seeckt, commanders fashioned the doctrine that the Wehrmacht was to employ in World War Two. Repelled by the waste and indecisiveness of trench warfare, they returned to the ideas of Schlieffen, and in 1921 the army published its new doctrine, Command and Combat with Combined Arms.
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).
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. Brandt and Sievers were executed in 1948 after being convicted during the Doctors' trial, part of the Subsequent Nuremberg trials.
Although she struggled with resentment towards her late husband for his womanizing and marital neglect, Emilie still had profound love for Schindler. Revealing her internal dialogue when she visited his tomb almost 40 years after his passing, she had said to him: "At last we meet again . . .I have received no answer, my dear, I do not know why you abandoned me . . . But what not even your death or my old age can change is that we are still married, this is how we are before God. I have forgiven you everything, everything. . ."
The existing legal system provides appropriate tools for the effective protection and management of the property. The Museum Council, whose members are appointed by the Minister of Culture and National Heritage, supervises the performance of the Museum’s duties regarding its collections, in particular the execution of its statutory tasks. In addition, the International Auschwitz Council acts as a consultative and advisory body to the Prime Minister of the Republic of Poland on the protection and management of the site of the former Auschwitz Birkenau camp and other places of extermination and former concentration camps situated within the present territory of Poland.
As the calibre of the orchestra improved under the baton of Laks, the SS began to make more frequent and diverse requests of the musicians. On Sundays they were forced to give concerts of ‘light’ music, and they expanded their repertoire to include excerpts from operas and operettas. They were also frequently given special requests by various guards. They composed special musical medleys in honour of SS officials' birthdays. Some Nazis regularly attended rehearsals, playing music with the musicians, and even on occasion befriending them. Members of the orchestra were also frequently commanded to entertain at late-night parties for camp VIPs and the guards.
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.
In 1993, Steven Spielberg’s Schindler’s List brought to the screen a story that had gone untold since the tragic events of the Holocaust. Oskar Schindler, a Nazi party member, used his pull within the party to save the lives of more than 1000 Jewish individuals by recruiting them to work in his Polish factory. Here are some facts about Spielberg’s groundbreaking film on its 25th anniversary.
^ Historian H.P. Willmott writes that, "Many examples of the experiences and losses suffered by German formations moving up to the front are well known. Panzer Lehr, for instance, on 7 June alone lost 84 half-tracks, prime movers and self propelled guns, 40 fuel bowsers, 90 soft-skinned vehicles and five tanks as it made its way from Le Mans to Caen.
In the final days of the war, just before the entry of the Russian army into Moravia, Schindler managed to smuggle himself back into Germany, into Allied-controlled territory. The wartime industrial tycoon was by now penniless. Jewish relief organizations and groups of survivors supported him modestly over the years, helping finance his (in the long run, unsuccessful) emigration to South America. When Schindler visited Israel in 1961, the first of seventeen visits, he was treated to an overwhelming welcome from 220 enthusiastic survivors. He continued to live partly in Israel and partly in Germany. After his death in Hildesheim, Germany, in October 1974, the mournful survivors brought the remains of their rescuer to Israel to be laid to eternal rest in the Catholic Cemetery of Jerusalem. The inscription on his grave says: 'The unforgettable rescuer of 1,200 persecuted Jews".
Measuring 270 by 490 metres (890 ft × 1,610 ft), the camp was larger than Auschwitz I. By the end of 1944, it housed 60 barracks measuring 17.5 by 8 metres (57 ft × 26 ft), each with a day room and a sleeping room containing 56 three-tiered wooden bunks. IG Farben paid the SS three or four Reichsmark for nine- to eleven-hour shifts from each worker. In 1943–1944, about 35,000 inmates worked at the plant; 23,000 (32 a day on average) died as a result of malnutrition, disease, and the workload. Deaths and transfers to Birkenau reduced the population by nearly a fifth each month; site managers constantly threatened inmates with the gas chambers. In addition to the Auschwitz inmates, who comprised a third of the work force, IG Auschwitz employed slave laborers from all over Europe. When the camp was liquidated in January 1945, 9,054 out of the 9,792 inmates were Jews.
Auschwitz was considered a comfortable posting by many SS members, because of its many amenities. SS personnel were initially allowed to bring partners, spouses, and children to live at the camp, but when the SS camp grew more crowded, Höss restricted further arrivals. Facilities for the SS personnel and their families included a library, swimming pool, coffee house, and a theater that hosted regular performances.
What the arms, whose charges can be partly traced in tithing seals and boundary stones back to the 16th century, mean is unclear. The charge that the German blazon describes as a “wall anchor” (Maueranker) is not accepted as such by everyone, with some saying it could have been meant to be taken as a weaver’s reel. With a document from 22 July 1926, the interior minister of the People's State of Hesse granted the community the right to bear these arms.
It is badly lighted, full of draughts, with the brick floor covered by a layer of mud. The water is not drinkable; it has a revolting smell and often fails for many hours. The walls are covered by curious didactic frescoes: for example, there is the good Häftling [prisoner], portrayed stripped to the waist, about to diligently soap his sheared and rosy cranium, and the bad Häftling, with a strong Semitic nose and a greenish colour, bundled up in his ostentatiously stained clothes with a beret on his head, who cautiously dips a finger into the water of the washbasin. Under the first is written: "So bist du rein" (like this you are clean), and under the second, "So gehst du ein" (like this you come to a bad end); and lower down, in doubtful French but in Gothic script: "La propreté, c'est la santé" [cleanliness is health].
The most infamous doctor at Auschwitz was Josef Mengele, the "Angel of Death", who worked in Auschwitz II from 30 May 1943, at first in the gypsy family camp. Particularly interested in performing research on identical twins, dwarfs, and those with hereditary disease, Mengele set up a kindergarten in barracks 29 and 31 for children he was experimenting on, and for all Romani children under six, where they were given better food rations. From May 1944, he would select twins and dwarfs during selection on the Judenrampe, reportedly calling for twins with "Zwillinge heraus!" ("twins step forward!"). He and other doctors (the latter prisoners) would measure the twins' body parts, photograph them, and subject them to dental, sight and hearing tests, x-rays, blood tests, surgery, and blood transfusions between them. Then he would have them killed and dissected. Kurt Heissmeyer, another German doctor and SS officer, took 20 Jewish children from Auschwitz to use in pseudoscientific medical experiments at the Neuengamme concentration camp. In April 1945, the children were killed by hanging to conceal the project.
Despite the continuing war with Great Britain, German forces invaded the Soviet Union in June 1941. At first, the German Blitzkrieg seemed to succeed. Soviet forces were driven back more than 600 miles to the gates of Moscow, with staggering losses. In December 1941, Hitler unilaterally declared war on the United States, which consequently added its tremendous economic and military power to the coalition arrayed against him. A second German offensive against the Soviet Union in 1942 brought German forces in the east to the shores of the Volga River and the city of Stalingrad. However, the Soviet Union launched a counteroffensive in November 1942, trapping and destroying an entire German army at Stalingrad.
Auschwitz-Birkenau, the largest of the concentration and extermination camps established on Polish soil, served concurrently as a labor camp and as a center for the rapid extermination of Jews. Chosen as the central location for the annihilation of the Jewish people, it was equipped with several extermination facilities and crematoria. Extermination was carried out by means of Zyklon B gas, a substance that had previously been tested on Russian prisoners of war.
The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.
After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939. He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office. As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland. One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops. Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.
