During the Holocaust, concentration camp prisoners received tattoos only at one location, Auschwitz. Incoming prisoners were assigned a camp serial number which was sewn to their prison uniforms. Only those prisoners selected for work were issued serial numbers; those prisoners sent directly to the gas chambers were not registered and received no tattoos.
The invasion of France consisted of two phases, Operation Yellow (Fall Gelb) and Operation Red. Yellow opened with a feint conducted against the Netherlands and Belgium by two armoured corps and paratroopers. Three days later, the main effort of Panzer Group von Kleist attacked through the Ardennes and achieved a breakthrough with air support. The group raced to the coast of the English Channel, dislodging the British Expeditionary Force, Belgian Army, and some divisions of the French Army. The motorized units initially advanced far beyond the following divisions. When the German motorized forces were met with a counterattack at the Battle of Arras (1940), British tanks with heavy armour (Matilda I & IIs) created a brief panic in the German High Command. The motorized forces were halted outside the port city of Dunkirk which was being used to evacuate the Allied forces. Hermann Göring had promised his Luftwaffe would complete the job but aerial operations did not prevent the evacuation of the majority of Allied troops (which the British named Operation Dynamo); some 330,000 French and British. Operation Red then began with XV Panzer Corps attacking towards Brest and XIV Panzer Corps attacking south, east of Paris, towards Lyon, and XIX Panzer Corps completing the encirclement of the Maginot Line. The defending forces were hard pressed to organize any sort of counter-attack. The French forces were continually ordered to form new lines along rivers, often arriving to find the German forces had already passed them.
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.
Eventually, the Germans ordered the councils to compile lists of names of deportees to be sent for "resettlement".[208] Although most ghetto councils complied with these orders,[209] many councils tried to send the least useful workers or those unable to work.[210] Leaders who refused these orders were shot. Some individuals or even complete councils committed suicide rather than cooperate with the deportations.[211] Others, like Chaim Rumkowski, who became the "dedicated autocrat" of Łódź,[212] argued that their responsibility was to save the Jews who could be saved and that therefore others had to be sacrificed.[213] The councils' actions in facilitating Germany's persecution and murder of ghetto inhabitants was important to the Germans.[214] When cooperation crumbled, as happened in the Warsaw ghetto after the Jewish Combat Organisation displaced the council's authority, the Germans lost control.[215]
In June 2016, the Auschwitz-Birkenau museum in the Polish town of Oswiecim re-discovered over 16,000 personal items belonging to victims of Auschwitz-Birkenau that had been lost in 1968. The items were originally discovered in 1967 by archaeologists excavating the concentration camp site, and were placed in 48 cardboard boxes in the Polish Academy of Sciences in Warsaw before being lost due to an anti-Semitic communist regime coming to power in 1968.
From the overpass, the road leads directly to the Gate of Death. The railroad spur line that goes through the gate house begins on the left side of the gate, about a quarter of a mile away, and curves around until it forms a straight line in front of the gate. Trains coming from the west entered the Birkenau camp from tracks on the left side of the gate, as you are facing it, and did not pass the railroad station in the town of Auschwitz. Trains coming from the opposite direction passed the train station in Auschwitz and then entered the camp on the spur line. The train tracks end only a few yards from two of the gas chambers inside the Birkenau camp.
In the course of the war, the camp was staffed by 7,000 members of the German Schutzstaffel (SS), approximately 12 percent of whom were later convicted of war crimes. Several, including camp commandant Rudolf Höss, were executed. The Allies did not act on early reports of atrocities at the camp, and their failure to bomb the camp or its railways remains controversial. At least 802 prisoners tried to escape from Auschwitz, 144 successfully, and on 7 October 1944 two Sonderkommando units, consisting of prisoners assigned to staff the gas chambers, launched a brief, unsuccessful uprising.
^ Many of the German participants of Operation Citadel made no mention of blitzkrieg in their characterisation of the operation. Several German officers and commanders involved in the operation wrote their account of the battle after the war, and some of these postwar accounts were collected by the US Army. Some of these officers are: Theodor Busse (Newton 2002, pp. 3–27), Erhard Raus (Newton 2002, pp. 29–64), Friedrich Fangohr (Newton 2002, pp. 65–96), Peter von der Groeben (Newton 2002, pp. 97–144), Friedrich Wilhelm von Mellenthin (Mellenthin 1956, pp. 212–234), Erich von Manstein (Manstein 1983, pp. 443–449), and others.
Auschwitz was considered a comfortable posting by many SS members, because of its many amenities.[84] 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.[80]
