The Evacuation of Children From Germany During World War II

The Need to Evacuate ChildrenChildren Given Priority During The EvacuationArrangement of Accommodation For The Evacuated ChildrenA Challenging Time For AllMany children, as well as their parents and their families, certainly went through difficult times when enemy forces descended on German cities with heavy aerial bombings. Although the bombings targeted factories, misguided bombs would often hit homes and schools endangering the lives of children. Fearing that the war would result in mass civilian deaths and affect its future generations, the German government under the leadership of Adolf Hitler ordered that children and mothers with infants be evacuated to rural locations and other parts of the country which were considered safer. The objective was to save children and infants from the enemy fire. The evacuation exercise happened in numerous phases. It is estimated that the first phase of children evacuation, that happened over a three day period, saw more than 800,000 children evacuees relocated by special trains and boats to the locations considered to be safe such as Saxony, Bavaria, and Prussia. As the war grew, the government...Get price

German evacuation from Central and Eastern Europe - Wikipedia

The German evacuation from Central and Eastern Europe ahead of the Red Army advance in World War II was delayed until the last moment. Plans to evacuate people from the territories controlled by Nazi Germany in Central and Eastern Europe, including from the former eastern territories of Germany as well as occupied territories, were prepared by German authorities only when the defeat was inevitable, resulting in utter chaos.

German Evacuation PoliciesRed Army Atrocities and Nazi PropagandaRussiaUkraineEast PrussiaPomeraniaSilesiaSee AlsoBibliographyThe plans to evacuate some German populations westwards from Eastern Europe and from some cities in the Eastern Gaue of Greater Germany were prepared by various Nazi authorities towards the end of the war. Some of the guards and inmates of the Majdanek camp were evacuated starting on April 1, 1944 (see also Death marches (Holocaust)). In most cases, however, the implementation of the plans was either delayed until Allied forces had already advanced into the areas to be evacuated, or it was prohibited entirely by the Nazi apparatus. Despite the rapid advances of the Red Army, the German authorities in many areas forbade leaving oneplace of residence without a permit and an officially valid reason. Millions of Germans were left in these areas until combat conditions overwhelmed them, as a direct result of both the draconian measures taken by the Nazis towards the end of the war against anyone even suspected of 'defeatist' attitudes (such as suggesting evacuation) and the fanaticism...Get price

Why the EU should ban sf6 gas

What Is insulating gas? and How Is It used?Is insulating gas A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf6 gas Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry sf6 gasis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.Get price
