and gas
wasn’t gas used against the bonus army?
After the cavalry charged, the infantry, with fixed bayonets and adamsite gas, an arsenical vomiting agent, entered the camps, evicting veterans, families, and camp followers. The veterans fled across the Anacostia River to their largest camp and President Hoover ordered the assault stopped. However Gen. MacArthur, feeling the Bonus March was a attempt to overthrow the U.S. government, ignored the President and ordered a new attack. Fifty-five veterans were injured and 135 arrested.[11] A veteran's wife miscarried. When 12-week-old Bernard Myers died in the hospital after being caught in the tear gas attack, a government investigation reported he died of enteritis, while a hospital spokesman said the tear gas "didn't do it any good."[15]
In all four were killed and 1,017 were injured. At least 69 police were injured.
