the polish government-in-exile in london tried to alert the world to the holocaust. one eyewitness reports that there was a shortwave transmitter hidden in block 11 of auschwitz concentration camp which sent information directly to london. between january 1942 and spring 1943, much of the coverage of the london "dziennik polski" was devoted to exposing the holocaust, and in late 1943 such topics as concentration camps and medical experiments were described in details.
