Along with
Thomas Douglas and
Hackston of Rathillet he, in 1679, drew up what became known as the "Rutherglen declaration", which they intended on 29 May, the king's birthday, to nail to the market-cross of Glasgow. The advance of the troops of
John Graham of Claverhouse prevented that, and
Rutherglen, about two miles to the east of Glasgow, was chosen instead. They extinguished the bonfire in the king's honour and lit another, where they proceeded to burn all the acts of parliament and royal proclamations made since the Restoration. They then retired towards Evandale and
Newmilns, preparing to hold an armed convention on the following Sunday at
Loudoun Hill.
Battle of Drumclog engraved by
G Greatbach Claverhouse, who had gone to Rutherglen, came suddenly in sight of the gathering. Sending away their women and children the covenanters drew up in battle array on the farm of Drumclog, a little to the east. Nominally Hamilton was in command, but the experienced officers, such as Hackston and Cleland, led the separate detachments of the Covenanters, defeating Claverhouse was due. Hamilton, however, showed some energy after the fight. In a vindication of his conduct, 7 December 1685, published in
Faithful Contendings displayed, for having put to death one of the prisoners after the battle with his own hand, he asserted that before the battle began he had given out the word that "no quarter should be given".
Battle of Bothwell Bridge The troops had barricaded
Glasgow, and the Covenanters were easily repulsed. They halted at the position occupied on the previous night, but on Claverhouse advancing towards them retreated to Hamilton. As Claverhouse was too weak to attack them here, they formed a camp, and according to Hamilton numbered within a week five or six thousand men. Hamilton took all the credit for the victory at Drumclog, and assumed command without ceremony. Time was spent in harangues and theological disputes. After the withdrawal of the government forces to
Stirling the Covenanters advanced to Glasgow, where they are stated to have robbed the archbishop's house, to have pulled down the ornaments of the cathedral, and to have defaced several of the monuments, but having done so they fell back on their old position. The arrival in the camp of John Welch, with a reinforcement of men from
Ayr, introduced a disturbing element. Welch was prepared to accept a compromise with the government by which both
episcopacy and
presbyterianism should be tolerated. He was therefore denounced by the Hamilton party as an
Erastian, and the dispute raged until the appearance of the government forces under the
Duke of Monmouth. Welch and others, though much in the minority, drew up a declaration, which they presented on 22 June in the hope that it would lead to at least a suspension of hostilities. The declaration is known as the Hamilton declaration, in reference to the town where it was drawn up. Sir Robert Hamilton, in name of the army, also signed a petition to Monmouth, and afterwards, when taunted with this, said that he had been ensnared into the subscription by the belief that it was
Donald Cargill's work. When the Hamilton declaration was presented, the armies were drawn up facing each other on opposite banks of the
River Clyde at Bothwell Bridge. Monmouth refused to consider terms until they had laid down their arms. Hamilton occupied himself with the erection of a gigantic gibbet, around which was placed a cartload of new ropes, but as soon as the action began his courage ebbed away. He ordered Hackston to retire when the bridge was attacked, and himself 'rode off with the horse' and 'allowed the foot to shift for themselves,' thus 'leaving the world to debate whether he acted most like a traitor, coward, or fool'. Hamilton's courage was doubted. Burnet, in a passage omitted from the earlier editions of his
Own Time,' calls him an 'ignominious coward,' and
Robert Wodrow speaks of his behaviour at Bothwell Bridge as 'ill conduct, not to say cowardice.' During the attack on Glasgow he is said to have waited the issue in a place of safety. In any case he was incompetent as a commander, and displayed feebleness. ==Later life==
