The Covenanters had established their camp on the south bank of the Clyde, north of
Hamilton. The rebels numbered around 6000 men, but were poorly disciplined and deeply divided by religious disagreements. They had few competent commanders, being nominally led by
Robert Hamilton of Preston, although his rigid stance against the Indulged ministers only encouraged division. The preacher
Donald Cargill and
William Cleland, the victor of Drumclog, were present, as were
David Hackston of Rathillet and John Balfour of Kinloch, known as Burley, who were among the group who murdered
Archbishop Sharp on 3 May. James Ure of Shirgarton led a troop of 200 men from
Stirlingshire at the battle and wrote an explanation of why the covenanters lost in his personal memoirs. The government army numbered around 5000 regular troops and militia, and was commanded by Monmouth, supported by Claverhouse and the
Earl of Linlithgow. The royalist troops were massed on the northern or Bothwell bank of the river Clyde on sloping ground that included a field that has since become known as the Covenanters Field - not because the battle was fought there but because for many years it was the venue for a covenanters conventicle organised by the Scottish Covenanters Memorial Association. The battle centred on the narrow bridge across the Clyde, the passage of which Monmouth was required to force in order to come at the Covenanters. Hackston led the defence of the bridge and had some initial success in the initial skirmishes at the bridge itself. But his men lacked artillery and ammunition, and were forced to withdraw after around an hour. Once Monmouth's men were across the bridge, the Covenanters were quickly routed. Many fled into the parks of nearby
Hamilton Palace, seat of
Duchess Anne, who was sympathetic to the Presbyterian cause, and it was in this area that the final engagements took place. The numbers of covenanters who were killed varies widely with estimates ranging from 7 - 700 according to the Scottish Battles Gazetteer. Around 1200 were taken prisoner. ==Aftermath==
