In April 1736, during the public hanging
of Andrew Wilson, a convicted smuggler charged with robbing
a customs officer, a riot broke out leading to the deployment
of National Guard soldiers armed with musket and ball.
The situation worsened when Captain John Porteous ordered
a warning shot above the heads of the rowdy crowd. Some
shots wounded residents standing behind the high apartment
windows and the ensuing chaos prompted the order from Porteous
to shoot into the crowd.
This resulted in six deaths and over 30 people were wounded.
He was convicted of murder on 5 July 1736, but a deferment
on execution transpired after a successful appeal, lodged
by Sir Robert Walpole, the first English Prime Minister.
This incensed the local population and inspired a plot
to kill Porteous. On September 7th the mob stormed the
infamous Tolbooth Prison at Parliament Square and overpowered
They dragged the despised officer through the Lawnmarket
to the Grassmarket where he was beaten and lynched from
a dyer's pole.
He died just before Midnight of September
10th and was buried in Greyfriars Kirkyard the following
day. Where his gravestone can still be found.
