A little of that kind of thinking would have been nice for Sarah
Simpson and Penelope Kenney, the first persons executed in Portsmouth
under the Colonial governorship of Benning Wentworth. The women were
found guilty of murdering a child. After being paraded through city
streets in a cart, and listening to a lengthy sermon in church
regarding their crime, Thomas Packer, the executioner, took the women
to a tree outside the city where they were strung up. The cart was
pulled slowly out from under them where they were left to strangle to
an agonizing death.
