Before the Germans captured the city of Warsaw during the 1939 Blitzkrieg, there were 360,000 Jews in the Polish capital. The Jews were forced into the Warsaw Ghetto, which was established on November 15, 1940.
Disease and starvation claimed many of the ghetto's inhabitants but the population was maintained by the continual influx of Jewish refugees. Warsaw’s Jewish population soon reached 460,000. The Jews of the Ghetto initially did not realize that they were being forced into what was a holding pen for the slaughterhouse – Treblinka, the death camp that would destroy eight hundred thousand people, the vast majority of whom were Jews, within the span of a few months.
On July 22, the eve of Tisha B’Av 1942, the death sentence for Warsaw’s Jews was issued. In the early morning hours the Judenrat was convened and the authorities for 'Resettlement Affairs' ordered the “resettlement in the east of all Jews residing in Warsaw regardless of age and sex.” The order called for six thousand Jews per day to be rounded up and deported.
A week before the announcement of the deportations, rumors had already spread in the ghetto. The Jews were gripped with terror. Head of the Judenrat, Adam Czerniakow asked the Nazi officials for an explanation, but received nothing but denials. On the 22nd of July, at 7:30 in the morning, Czerniakow, along with the members of the Judenrat, were told that the deportations were to begin the next day -- Tisha B’Av -- and the expulsions would include children.
He immediately understood the gravity of such an order and that his previous cooperation with the Germans was a grievous error. This was an order he refused to sign. The night following the first deportation, he took his own life, leaving the following note, “I am powerless my heart trembles in sorrow and compassion. I can no longer bear all this.”
The diary A Cup of Tears, by Abraham Lewin, offers the following description of the events that occurred on that day, “Disaster after disaster, misfortune after misfortune. The small ghetto has been turned out on to the streets. ... Rain has been falling all day. Weeping. The Jews are weeping. They are hoping for a miracle. The expulsion is continuing. Buildings are blockaded.”
Chaim Kaplan, in his diary on the Warsaw Ghetto, foresaw the doom that awaited the Jews of Warsaw with the issuance of the decree. He had surmised that the deportations can only be a death sentence and those who deny it, “grasp at straws.” In a July 26 entry, Kaplan wrote, “We, the inhabitants of the Warsaw ghetto are now experiencing the reality. Our good fortune is that our days are numbered --that we shall not have to live long under conditions as these.”
The decree ordered all Jews to be deported except those who worked in German industries or the Judenrat. Over the next nine days 66,701 Jews were deported to Treblinka.
At Treblinka, a sign displayed at the entrance intended to maintain calm stated, “Do not worry about your future. … all of you are headed for the east, to work; while you work, your wives shall take care of your houses. But first you must bathe and your clothes must be cleaned of lice.”
Only moments later, after merciless beatings by SS and Ukrainian guards, the victims were herded into the crematoria.
On July 29, the next round of Warsaw’s deportations began. The SS, along with Latvian and Lithuanian troops, closed off individual blocks as forced people from their homes. Many were shot on the spot; others were savagely beaten. When the crowd’s numbers reached a few thousand, they were herded off to the “Umschlagplatz”—a deportation railway yard, to be transported.
Every morning and evening, the roundups took place. Over the month of August, 142,525 were deported, with 135,120 Jews being sent to Treblinka. By mid August, it was widely understood that “resettlement” was a myth. Enough evidence had already reached the ghetto by witnesses to Nazi atrocities. By October 3, 310,000 Jews were deported, including most members of the Judenrat.
Many were deported on September 21--Yom Kippur, the Day of Atonement.
Hillel Seidman in his diary of the Warsaw Ghetto, wrote in an entry he entitled The Night of Tears, “As Night falls I finally reach home, my brain bursting with terrifying images. Crossing our courtyard I notice our small shtiebl. About twenty men sit on upturned benches – it’s Tisha B’Av tonight! Two flickering candles dimly light up the bent heads, with their eyes staring into the far distance, as that heartrending tune wells up: “Eichah…”
“The tune that was perhaps first composed at the exile from Jerusalem and has since absorbed the tears of generations.
“We Jews of Warsaw, sons of those exiles, sit on the ground to mourn our own personal churban, the destruction of a major kehillah – the largest and most vigorous in Europe – which resulted from that earlier Churban. We weep at our fate, a nation without a land, within the grasp of our fiercest enemy and condemned to death. We grieve both for the loss of the Beis Hamikdash and the extinction of our lives.” 
On Tisha B’Av 1942, the well-organized Nazi killing machine whose horror knew no bounds was set into high gear in the city of Warsaw. Other ghettos would face the same fate.
A chronicler of the Warsaw ghetto, Emanuel Ringelbaum, called the eve of that Tisha B’Av in 1942 “The blackest day in Jewish history in modern times.”

 Of the forty thousand Jews who remained in the Warsaw Ghetto following the deportations, several hundred armed themselves and fought against their oppressors when they came to liquidate the ghetto in April of 1943.
