The latest blog post is dedicated to the memory of tens of thousands of Hungarian Jewish men and women, dragged off for slave labour by the Nazi ally Arrow Cross government in November 1944. László Csősz, historian and senior archivist of the Hungarian National Archives combined letters and diaries of victims and survivors of the "death marches” with testimonies culled from the protocols of the National Committee for Attending Deportees, one of the largest early documentation projects on the Holocaust. Focusing on a factor and a source largely neglected in Holocaust studies, the blog post features an experimental interactive map, which displays the route of the forced marches with weather icons and historical meteorological data.
