"Altogether 500,000 people were killed by the bombing in Germany and more than 800,000 injured. In the last four months of the war alone, when the bombing campaign was at its most ferocious, at least 130,000 people died. The result was casualties on a colossal scale—so much so that Germany in January 1945 became the site of what perhaps was the greatest killing frenzy had ever seen. 

"In January 1945 alone, more than 450,000 German soldiers lost their lives (a considerably greater number of soldiers than either the United Kingdom or the United States lost during the entire war). In February, March, and April, the number of German military dead approached three hundred thousand per month.

"The chaos and extreme violence of the last stages of the Second World War turned the continent of Europe into a gigantic prison and a sea of blood. If there was a distillation of Nazism, it lay in the senseless destruction of human life during the final months of the war. In the end, all Nazism had to offer was war and destruction, war without end or an end through war.

Hitler: "May it become, at some future time, part of the code of honor of the German officer, as it is already in our Navy, that the surrender of a district or of a town is impossible, and that the leaders here above all must march ahead as shining examples, faithfully fulfilling their duty unto death."
