when did germany first use poison gas in ww1
Chemical weapons in World War I The first instance of large-scale use of gas as a weapon was on 31 January 1915, when Germany fired 18,000 artillery shells containing liquid xylyl bromide tear gas on Russian positions on the Rawka River, west of Warsaw during the Battle of Bolimov. However, instead of vaporizing, the chemical froze and failed to have the desired effect.[8]
Gas chamber As of 2010, the last person to be executed in the gas chamber was German national Walter LaGrand, sentenced to death before 1992, who was executed in Arizona on March 3, 1999. The U.S. Court of Appeals for the Ninth Circuit had ruled that he could not be executed by gas chamber, but the decision was overturned by the United States Supreme Court.[16] The gas chamber was formerly used in Colorado, Nevada, New Mexico, North Carolina and Oregon. Six states, Arizona, California, Maryland, Mississippi, Missouri and Wyoming, authorize lethal gas if lethal injection cannot be administered, the condemned committed their crime before a certain date, or the condemned chooses to die in the gas chamber.[21] In October 2010, Governor of New York David Paterson signed a bill rendering gas chambers illegal for use by humane societies and other animal shelters.[22]
