When, however, the success at Loudoun Hill was spread abroad, a number of preachers, gentlemen, and common people, who had embraced the more moderate doctrine, joined the army of Hamilton, thinking, that the difference in their opinions ought not to prevent their acting in the common cause. The insurgents were repulsed in an attack upon the town of Glasgow, which, however, Claverhouse, shortly afterwards, thought it necessary to evacuate. They were now nearly in full possession of the west of Scotland, and pitched their camp at Hamilton, where, instead of modelling and disciplining their army, the Cameronians and Erastians (for so the violent insurgents chose to call the more moderate presbyterians) only debated, in council of war, the real cause of their being in arms. Hamilton, their general, was the leader of the first party; Mr John Walsh, a minister, headed the Erastians. The latter so far prevailed, as to get a declaration drawn up, in which they owned the king's government; but the publication of it gave rise to new quarrels. Each faction had its own set of leaders, all of whom aspired to be officers; and there were actually two councils of war issuing contrary orders and declarations at the same time; the one owning the king, and the other designing him a malignant, bloody, and perjured tyrant. Meanwhile, their numbers and zeal were magnified at Edinburgh, and great alarm excited lest they should march eastward. Not only was the foot militia instantly called out, but proclamations were issued, directing all the heritors, in the eastern, southern, and northern shires, to repair to the king's host, with their best horses, arms, and retainers. In Fife, and other countries, where the presbyterian doctrines prevailed, many gentlemen disobeyed this order, and were afterwards severely fined. Most of them alleged, in excuse, the apprehension of disquiet from their wives.[A] A respectable force was soon assembled; and James, duke of Buccleuch and Monmouth, was sent down, by Charles, to take the command, furnished with instructions, not unfavourable to presbyterians. The royal army now moved slowly forwards towards Hamilton, and reached Bothwell-moor on the 22d of June, 1679. The insurgents were encamped chiefly in the duke of Hamilton's park, along the Clyde, which separated the two armies. Bothwell-bridge, which is long and narrow, had then a portal in the middle, with gates, which the Covenanters shut, and barricadoed with stones and logs of timber. This important post was defended by three hundred of their best men, under Hackston of Rathillet, and Hall of Haughhead. Early in the morning, this party crossed the bridge, and skirmished with the royal van-guard, now advanced as far as the village of Bothwell. But Hackston speedily retired to his post, at the western end of Bothwell-bridge.
