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. On the morning of Sunday 1 June, the Rev. 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.
