I thought that everyone in the world knew that Anne Frank died from an illness in the Bergen-Belsen camp and that everyone knew the approximate date that she died, but apparently I was wrong.

Anne Frank was not executed by the Nazis. She was crammed onto a cattle train that took her to Auschwitz, but she did not die there. She died at Bergen-Belsen.
I wrote about Bergen-Belsen, the place where Anne Frank died, on my website at http://www.scrapbookpages.com/BergenBelsen/Introduction.html
The following quote is from my website:
Bergen-Belsen was the name of an infamous Nazi camp which has become a symbol of the Holocaust that claimed the lives of 6 million Jews in Europe more than sixty years ago. In 1943, Bergen-Belsen was initially set up as a detention camp (Aufenthaltslager) for prisoners who held foreign passports and were thus eligible to be traded for German citizens being held in Allied internment camps. In December 1944, Bergen-Belsen became a concentration camp under the command of Josef Kramer, the former Commandant of the Auschwitz II camp, also known as Birkenau.
A section for sick prisoners, who could no longer work in the Nazi forced labor camps, was set aside at Bergen-Belsen in March 1944. In 1945, when World War II was drawing to a close, civilian prisoners were evacuated from other concentration camps as Soviet troops advanced westward; thousands of these prisoners were brought to the Bergen-Belsen camp which was not equipped to handle such a large number of people.
Finally, Bergen-Belsen itself was right in the middle of the war zone where bombs were falling and Allied planes were strafing the Autobahn and the railroads. British and Germans troops were doing battle on the Lüneberg heath right outside the camp. In February 1945, the situation at Bergen-Belsen became catastrophic when a typhus epidemic broke out in the crowded camp.
