The first method of murder was mass shootings, killing around one and a half million Jews. The Nazi's were on a mission to prove an effective way of killing off all Jews. Their first solution was mass shootings. The Jews were captured or arrested and taken to the Krepieck forest. There the Nazis forced the Jews to dig their own grave. Digging graves was intensive work. They dug each grave for three days and nights in two shifts of one hundred and fifty people. Each grave was more than two meters deep, zigzag shaped, and about one hundred meters long (Krepieck Forest). After a torturing three days of hard work, Jews were lined around the graves and shot so that they would fall into the grave. Many of the people placed in charge of the shootings faced emotional issues. This then led to the discovery of more cruel methods of mass destruction. "Every Human being has his own fate." Remarked by Moshe the beadle, in the novel Night (Yahoo answers).Moshe the beadle said this to show that not everyone was going to die the same way, but they all have a gate they will enter when they reach heaven.
The Nazis used the most horrific methods of murder on Jew, Gypsies, and other "undesirables." Other deadly methods were gas chambers and gas trucks. This was by far the most effective killing method (Holocaust education). The procedure for these deadly methods was forcing Jews into a compact concrete room or an automobile. The Nazis then injected the air with deadly gases called, Zyklon B and Carbon Monoxide. Zyklon B, a poisonous gas, was poured through openings of the gas chambers, and trickled down over the people. Carbon Monoxide was injected into the chambers and trucks suffocating and smothering the people who inhaled the chemical.
