Is that a new record!?!
At the outbreak of the Civil War, the Army hanged 38 Sioux in the largest mass hanging in U.S. history.

Our best year was 1935, with 197 executions, mostly by electrocution.

Of the 15,717 people executed in the United States the majority, 9183, were by hanging, mostly in the 19th Century. Two men were hanged in Plimoth colony for killing an Indian. (A third fled to avoid trial and was never seen again. He almost certainly died in the wilderness.)
