Had he done so, with his force strengthened by the Continental bayonets, and new supplies of powder for his rifles, Watson's flight to Georgetown, which he could scarcely have reached, would have been far more uncomfortable than he found it on the previous occasion.
Lee led the way with his legion towards the Santee, while Marion, placing Witherspoon with a small party on the trail of Watson, pursued his line of march through Williamsburg. Having once resolved, Marion's movements were always rapid and energetic.
On the fifteenth of April, only a day after the junction with Lee, he was before Fort Watson.
This was a stockade fort, raised on one of those remarkable elevations of an unknown antiquity which are usually recognized as Indian mounds.
It stands near Scott's Lake on the Santee river, a few miles below the junction of the Congaree and Wateree. The mound is forty feet in height, and remote from any other elevation by which it might be commanded.
The garrison at this post consisted of eighty regular troops, and forty loyalists. It was commanded by Lieut. McKay, a brave officer, of the regular service. To the summons of Marion he returned a manly defiance, and the place was regularly invested.
Besieged and besiegers were alike without artillery; with a single piece, the former might well have defied any force which Marion could bring against him. The place would have been impregnable to the Americans.
As it was, its steep sides and strong palisades forbade any attempt to storm.
To cut off the garrison from Scott's Lake, where it procured water, was the first step taken by the besiegers. But the besieged, by sinking a well within the stockade, below the level of the contiguous water, counteracted the attempt. For a moment, the assailants were at fault, and, without artillery, the prospect was sufficiently discouraging.
But while doubting and hesitating, Col. Mayham, of the brigade, suggested a mode of overawing the garrison which was immediately adopted.
At a short distance from the fort there grew a small wood, a number of the trees of which were hewn down, and transported upon the shoulders of the men within a proper distance of the mound.
Here, during the night, all hands were actively employed in piling the wood thus brought, in massive and alternate layers, crosswise, until the work had reached a sufficient elevation. At dawn, the garrison were confounded to find themselves, at wakening, under a shower of rifle bullets. Thus overlooked, the fort was no longer tenable; and a party of volunteers from the militia, headed by Ensign Baker, and another of Continentals, from the legion, led by Mr. Lee, a volunteer, ascended the mound with great intrepidity, and gained the abbatis, which they proceeded to destroy. This movement brought the garrison to terms, and a capitulation immediately followed.
But the leaguer had consumed eight days, the progress of which had been watched with equal anxiety by both parties. The Americans apprehended, and the garrison anticipated, the approach of Watson with an overwhelming force for the relief of the besieged.
But Watson did not appear. He no longer had an overwhelming force.
His flight to Georgetown was marked by loss and desertion.
It appears that his panic, or his sense of duty, led him rather to avoid Marion and to reach Camden without interruption.
He very prudently, therefore, after crossing the Santee, on the route from Georgetown, moved down by Monk's Corner, added to his force the garrison of that place, and then cautiously advanced to the Santee.
He resolved rather to leave Fort Watson to its fate, than risk a force which might be necessary to the exigencies of Rawdon.
Watson was considered by the British one of their best partisans, yet never had poor warrior been so worried and harassed, as, with a superior force, he had been by Marion. Yet, in his second expedition in pursuit of the latter, had he been able to cooperate with Doyle, with the Tories of Harrison and Gainey, all preparing for the same object, the escape of our partisan would have been miraculous. At no time, during their pursuit of him, was his force equal to the smallest one of theirs. He must have been expelled the country, as he himself seemed to apprehend, or he must have fallen in the conflict.
We have so little at the hands of Marion, in the shape of correspondence, that we are tempted to give his official letter to General Greene, apprising him of the fall of Fort Watson. It is dated --Fort Watson (Scott's Lake), April 23, 1781.
Sir-- Lieut.-Col. Lee made a junction with me at Santee, the 14th inst., after a rapid march from Ramsay's mill, on Deep River, which he performed in eight days. The 15th we marched to this place and invested it.
Our hope was to cut off their water. Some riflemen and Continentals immediately took post between the fort and the lake. The fort is situated on a small hill, forty feet high, stockaded, and with three rows of abbatis round it. No trees near enough to cover our men from their fire.
The third day after we had invested it, we found the enemy had sunk a well near the stockade which we could not prevent them from [doing];as we had no entrenching tools to make our approach, we immediately determined to erect a work equal in height to the fort. This arduous work was completed this morning by Major Maham, who undertook it.
We then made a lodgment on the side of the mound, near the stockade.
