On this day in 1942, the Nazis began to implement the Grossaktion (Great Action) as part of the Final Solution. Under the guise of resettlement in the East, between 250,000 and 265,000 Jews were deported to Treblinka, Poland within merely two months. This event also occurred on Tisha B'Av of that year and is commemorated as one of the many tragedies to befall the Jewish People on this day.On July 20, the SS appeared in the ghetto, notifying the Warsaw Judenrat (Jewish council) of the new policy. As the Nazis withheld the truth about the deportations to newly-completed Treblinka, the Judenrat compiled a list of names for the first transports. This meant that all the Jewish people living in Warsaw were to be resettled in the East except for those employed by the German authorities, the Judenrat, the Jewish police, or other areas of work that aided the Nazi regime. On July 23, when word circulated in the ghetto about the true intentions of the deportations, Adam Czerniaków, head of the Judenrat, committed suicide. He did, however, obtain exemptions for numerous inhabitants who were not part of the previous list of exemptions.With the knowledge that Jews were sent directly to the gas chambers upon arrival at Treblinka, inhabitants began creating bunkers and other hiding places. This ultimately led to the creation of the Jewish Fighting Organization (ŻOB) and the birth of armed resistance in the ghetto.Between 5,000 and 7,000 people were deported daily, some of whom chose to be deported after hearing the false promises of free food and better work after arriving at their destination, as well as improved living conditions. During the Grossaktion, 35,000 Jews were murdered within the ghetto walls and by the summer of 1943, only 60 to 70,000 Jews remained in the ghetto, a fraction of the previous Jewish population in Warsaw.
