Lord Derwentwater unfortunately adopted a course which could but have one termination. He concealed himself from those who were employed to apprehend him. Clear from any direct imputation, had he then given himself up, he would have been released; and he might have been deterred from a participation in the disastrous scenes which ensued. He had now two children, a son and a daughter. He had many valuable considerations to forfeit for the one abstract principle of indefeasible right to the throne. Few men had more to venture. Many of the Jacobites went into the field with tarnished characters, and with ruined fortunes: they might gain,—they could not lose by the perilous undertaking. Amid the bands of high-born and highly principled men who co-operated in both the Rebellions, adventurers would appear, whose previous lives shed dishonour upon any cause; but the irreproachable, the prosperous, the beloved, could desire little more for themselves than what they already possessed: they ventured their rich and glorious barks upon the current; and let those who sully every motive with suspicion, say that there was no virtue, no patriotism, in the Jacobite party.

By his own descendant, Lord Derwentwater is believed to have hesitated upon the verge of his fate, but to have been urged into it by his brother Charles. Young and ardent, courageous even to rashness, the first to offer himself where an enterprise was the most hazardous, seeming to set no value upon his life where glory was to be obtained, the darling of his party, and, to sum up the whole, only twenty-two years of age, Mr. Radcliffe rashly drew his brother into a confederacy, so agreeable to his own ambitious and fearless spirit. But there was another individual on whom the responsibility of that luckless movement in the North must chiefly rest. This was Mr. Thomas Forster the younger, of Etherston in the county of Northumberland, and member for the county. During the first thirty years of his life, this gentleman had scarcely been known beyond the precincts of his paternal estate. He became a member of Parliament, and was drawn into the vortex of party without talents to adorn or judgment to guide his conduct. Although a Protestant, Mr. Forster soon made his house the place of rendezvous for all the non-jurors and disaffected people of the county in which he lived; and he became involved in the dangers of their schemes, almost before he was aware of the perils which he was about to encounter. The party of the Jacobites was composed of very dissimilar materials. Whilst some adopted its projects to retrieve character, or to attain, as they vainly hoped, fortune, whilst others were actuated by genuine motives, there were many who mingled in the mazes of the intricate politics of that day from vanity, and the love of being at the head of faction: such was Forster; and his career was unsatisfactory and inglorious as his character was weak.

A warrant for Mr. Forster's apprehension having been sent forth, he was, like Lord Derwentwater, obliged to fly from place to place, until he arrived at the house of Mr. Fenwick, at Bywell. Lord Derwentwater, meantime, had been secreted under the roof of a man named Lambert, in a cottage, where he had remained in safety. His horses had been seized by one of the neighbouring magistrates, and had been detained in custody for several weeks, pursuant to an order in council; yet, when he had need of them they were returned. "I afterwards asked that lord," Mr. Patten relates, "how he came so quietly by his horses from the justice's possession, whom the believing neighbourhood esteemed a most rigid Whig. I was answered thus, by that lord's repeating a saying of Oliver Cromwell's, 'that he could gain his ends with an ass-load of gold,' and left me to make the application."[188]

Mr. Fenwick, of Bywell, was a secret, though not an avowed Jacobite; and it was soon agreed that at his house should be collected all those who were favourable to the cause. A meeting of the party was accordingly held: it was decided that finding there was now no longer any safety in shifting from place to place, and that since, in a few days they might all be hurried up to London, and secured in prisons, where they might be separately examined, and induced to betray each other;—it was now time to appear boldly in arms, and to show the loyalty of the confederates to King James.

In pursuance of this resolution, the place and hour of meeting were appointed the very next morning; the sixth of October was named, and all were to assemble at Greenrig. Here those who rode from Bywell were met by Mr. Forster, with a party of twenty gentlemen. The meeting might have recalled the days of the Cavaliers: the winding of the river Tyne in the valley; the rural village of Bywell; on the rising ground to the right a ruin, once the fortress of the vale, and held in former times by the Baliols, presented a scene of tranquil beauty, which some who met that day were destined never to look upon again.

The low situation of Greenrig was deemed inconvenient for the purpose of the insurgents, and the party ascended a hill called the Waterfalls, from which they could see the distant country. This spot is thus described: "As you look upon Bywell from the most pleasing point of view, the landskip lies in the following order:—from the road near the front of the river, the ruined piers of a bridge become the front objects; behind which, in a regular cascade, the whole river falls over a wear, extended from bank to bank, in height above eight feet perpendicular; a mill on the right hand, a salmon lock on the left: the tower and the two churches stretch along the banks of the upper basin of the river, with a fine curvature; the solemn ruins of the ancient castle of the Baliols lift their towers above the trees on the right, and make an agreeable contrast with the adjoining mansion-house. The whole background appears covered with wood."[189]

On this height Mr. Forster and his party paused; but they had not been long there before they saw the Earl of Derwentwater, who came that morning from Dilstone, advancing. He was attended by several friends and by all his servants, some mounted on his coach-horses, and all well armed. As they marched through Corbridge, this gallant troop drew their swords. They were reinforced by several other gentlemen at the house of Mr. Errington, where they stopped; and they then advanced to the spot where their friends awaited their approach. They now mustered sixty horse, mostly composed of gentlemen and their attendants. After a short council it was decided that they should proceed towards the river Coquet, to Plainfield: here they were joined by several stragglers: they marched that evening to Rothbury a small market-town, where they remained all night, and continued their march on the following morning, the seventh of October, to Warkworth Castle.

In thus assembling his friends and his tenantry, Lord Derwentwater was not blameless of undue influence and oppression. The instances, indeed, of threats and absolute compulsion being used to augment the forces of the Jacobites, and to draw unwilling dependants into participation, are very numerous; they may be collected from various petitions, borne out by evidence, among the State Papers for 1715 and 1716. It is true that such excuses were certain to be alleged by many persons unjustly; but, where the charges were substantiated, we must with pain confess that the virtues of the Earl of Derwentwater, as well as those of other Jacobites, are sullied by a violent exercise of power over their tenantry. One man, named George Gibson, afterwards, in memorialising Lord Townshend from Newgate, affirms that upon his refusal to carry a message from Lord Derwentwater to Mr. Forster, two days before the insurrection, and returning to his own house instead, he was one night dragged out of bed by seven or eight men, and hurried off to serve in the said insurrection without a single servant of his own attending him. It was proved also, by King's evidence, that the unfortunate man did all in his power to escape from Kelso, and really made the attempt; but it was defeated, for he was ever an object of suspicion to the Earl of Derwentwater and Mr. Forster, whose watchfulness kept him among the rebel troops.[190] Party may do much to blunt the feelings; yet there was too much of what was good in the character of Lord Derwentwater for him, in the solitude of his own prison, not to remember in after days the heavy responsibilities which even by one act of this nature he had incurred, in compelling a man to act against his will and conscience.

Warkworth was probably chosen as a resting-place for the insurgents, on account of its strength. Situated only three-quarters of a mile from the sea, on the river Coquet, over which is thrown a bridge, guarded by a lofty tower, the Castle of Warkworth, which guards the town, commands a view both varied with objects of interest and importance.

From a lofty turret of the castle a great extent of land and ocean is to be seen. The great Tower of the Percys, from which this turret rises, is decorated with the lion of Brabant, and is seated on the brink of a cliff above the town. From this lofty structure the eye, stretching along the coast, may discern the castles of Dunstanbrough and Bamborough: the Fern Islands, dotted upon the face of the waters, the Port of Alemouth, and, at a little distance, the mouth of the river Coquet, with its island and ruined monastery. To the north, a richly cultivated country extends as far as Alnwick; to the south lies a plain, interspersed with villages and woods; the shore, to which it inclines, is indented with many ports and creeks; the smoke rising from many scattered hamlets, and the spires of churches enliven the smiling prospect.
