 Poles were, by nationality, the most numerous persons who rescued Jews during the Holocaust.To date, ethnic Poles have been recognized by the State of Israel as Righteous among the Nations – more, by far, than the citizens of any other country.The Home Army (the Polish Resistance) alerted the world to the Holocaust through the reports of Polish Army officer Witold Pilecki, conveyed by Polish government-in-exile courier Jan Karski.
