The author of the article ‘Martyrdom of the Catholic clergy in the Diocese of Lodz during the Second World War’ presents in an interesting and well documented way the poignant pages of the history of ecclesiastics from Lodz at the time of the Second World War. At the outbreak of the war, the Diocese of Lodz comprised 357 diocesan priests. As many as a hundred and fifty-five of them failed to live through the war. They either passed away through military action, in concentration camps, or died a natural death in the dire straits under the Nazi occupation. Not to mention those priests who ended their lives shortly after the war as a result of the traumatic events they had experienced in the camps, often in the aftermath of the pseudo-medical experiments they had been subjected to.
