At the Battle of Bothwell Bridge in 1679, over 1200 covenanters were taken prisoner and taken to Edinburgh . Approximately 400 of these prisoners were held in the Covenanters Prison in Greyfriars Churchyard.
Here they were kept out in the open, exposed to the elements for the winter months. They were kept under guard by tyrant George "Bluidy" MacKenzie.
The prisoners were given 4 ounces of bread and water each day. Those that died under these conditions were buried in the part of the kirkyard reserved for criminals. Those that survived the winter were either executed come spring, or shipped off to Barbados as slaves. Of those who were executed, some 100 were burned and their ashes buried under the Martyrs Memorial.
Although quite weathered, the inscription reads:
Halt passenger take heed what thou dost see
This tomb doth shew for what some men did die
Here lies interr'd the dust of these who stood
Gainst perjury resisting unto blood
Adhering to the Covenants and Laws
Establishing the same which was the Cause
Then their lives were sacrificed unto the Lust
Or Prelatist's abjur'd though here their dust
Lies mixt with murders and other crew
Whom justice did justly to death pursue
But as for this in them no cause was found
Worthy of death but only they were found
Constant and steadfast zealous witnessing
For the prerogatives of CHRIST their king
Which truths were feared by famous Guthrie's head
And all along to Mr Ranwick's blood
They did endure the wrath of enemies
Reproaches torments deaths and injuries
But yet they're these who from such troubles came
And now triumph in glory with the LAMB
