After several marches and skirmishes the Duke of Monmouth took post at Bridgewater; and the Earl of Feversham, having sent a troop of the ROYAL DRAGOONS, commanded by Captain Coy, to Lamport, to secure that pass, and to gain intelligence in the event of the rebels marching westward, advanced with the royal army to Weston (about three miles from Bridgewater), where he arrived on Sunday, the 5th of July. Having quartered the cavalry in the village, and ordered the infantry to encamp on a plain fronting _Sedgemoor_, he sent a party of life guards to patrole in the direction of Bristol, and posted a piquet of fifty of the ROYAL DRAGOONS with a squadron of the blues supported by one hundred men of the royal regiment of foot, on the moor, in front of the camp. A guard of the ROYAL DRAGOONS was also posted over the artillery, which consisted of sixteen pieces, and was drawn up on the high road from Weston to Bridgewater. During the night the Duke of Monmouth marched out of Bridgewater with the view of surprising the royal army; but the piquet in advance gave the alarm, and after exchanging a few shots with the rebels, retreated to the camp, and formed on the right of the infantry; at the same time the remainder of the ROYAL DRAGOONS, being aroused in their quarters in the village of Weston, turned out in the dark in good order, and formed on the left of the foot. The rebels commenced the attack with loud shouts,--the contest became general along the whole line,--and the moor sparkled with fire. The rebel horse soon gave way and fled in disorder; but their infantry stood firm and fought with great resolution. Day at length began to break; and the King's foot advancing to the charge, whilst the ROYAL DRAGOONS and other cavalry attacked the flanks of the rebels and put them in disorder, their whole line then gave way and fled in confusion, and were pursued across the moor and adjoining corn-fields with great slaughter. Two troops of the ROYAL DRAGOONS continued the pursuit as far as Bridgewater, where they were ordered to halt by the Earl of Feversham. In the mean time Captain Russel's troop of the ROYAL DRAGOONS had been attached to three Scots regiments of foot, which had recently arrived from Holland under the command of Major-General Mackay, and ordered to join the army in the west; but, on the news of Monmouth's defeat at Sedgemoor, these forces were directed to halt at Bagshot; the ROYAL DRAGOONS were subsequently dispersed in small parties into the adjoining counties to seize suspected persons; the Scots regiments returned to Hounslow, and, after encamping a short time on the heath, re-embarked for Holland.
