Despite increasing repression after the Nazis came to power , Cohn still felt connected to Germany and remained in Breslau with his second wife and two daughters . In his diaries , he documented life under Nazi rule and the subsequent destruction of Breslau 's Jewish community , then the third largest in Germany . As the persecution of Jews in Germany grew worse , the Cohns considered emigration . Cohn and his wife visited Palestine in 1937 , but it offered no employment prospects to Cohn , who was not healthy enough to perform physical labor . When they wanted to flee after the Kristallnacht in 1938 , it was too late ; after the outbreak of the Second World War , the Nazi regime no longer allowed emigration . The Cohns endured the Nazi reign of terror in Breslau ; they were arrested on November 21 , 1941 and deported to German-occupied Lithuania . A few days later , on November 29 , 1941 , Cohn and his family were shot in the Ninth Fort , together with 2000 other Jews from Breslau and Vienna . In 2010 , a plaque commemorating Cohn was unveiled on Wrocław 's Market Square
