Following the assassination of Archbishop James Sharp on Magus Muir and the Declaration of Rutherglen, the Covenanters were on the verge of open rebellion.
A large conventicle was planned to take place at Loudoun Hill, on the boundary of Ayrshire and Lanarkshire, in defiance of government persecution of the Covenanters.
Thomas Douglas allegedly broke off his sermon with the words "Ye have got the theory, now for the practice", when it was reported that the dragoons of Claverhouse were heading to the area.
Claverhouse, better known to his enemies as 'Bluidy Clavers', had recently been appointed captain, with a mission to disperse conventicles in south west Scotland.
Just three weeks later Claverhouse, under the leadership of the Duke of Monmouth, helped to crush the rebellion at the Battle of Bothwell Brig.
A dubious account of the battle, attributed to the Laird of Torfoot allegedly written by Thomas Brownlee of the Covenanter army, was published in 1822.
In 1905 the Darvel and Strathaven Railway opened, with a station at Drumclog, 1.2 miles (1.9 km) south west of the battle site.
