In 3-5 sentences, analyze how the Germans tried to hide the Holocaust from most of the world during the war.

The Nazi regime used rail transport as one of the ways to forcibly redistribute the ethnic composition of Eastern Europe during World War II. In 1941, the Nazi elite embarked on a policy of "the final solution of the Jewish question" through the systematic mass extermination of Jews living in Europe. The authorities of fascist Germany used the railways crossing the continent to transport or deport Jews from their places of residence, mainly Eastern European countries. When the German authorities began to carry out regular massacres of Jews in specially built death camps, the Jews were sent to these camps by train or, if it was not possible to use railway transport in the case of short distances, either by truck or on foot. The Germans tried to hide their intentions. They tried to convince their allies to carry out the deportations with the aim of "relocating" Jews to labor camps "in the east." The phrase "resettlement to the east" has become a euphemism for the transportation of Jews to death camps for massacres.
