On 29 November, 1941, my grandmother, Ilse Cohn, was shot here, in this field, by members of the Nazi death squad Einsatzkommando 3, under the command of a Swiss-born SS colonel called Karl Jäger. On that one day alone, they murdered 2,000 Jews who had been deported by train from Vienna and from my grandmother's hometown of Breslau. So I have come to honour my grandmother's memory. My mother was her only child and although Ilse had three brothers, she had no nephews or nieces. My brother and I, and my two children, are her only living relatives.
