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. This was performed with great spirit and address by Ensign Johnson, and Mr. Lee, a volunteer in Col. Lee's legion, who with difficulty ascended the hill and pulled away the abbatis, which induced the commandant to hoist a flag. Col. Lee and myself agreed to the enclosed capitulation, which I hope may be approved by you. Our loss on this occasion is two killed, and three Continentals and three militia wounded. I am particularly indebted to Col. Lee for his advice and indefatigable diligence in every part of these tedious operations, against as strong a little post as could well be made, and on the most advantageous spot that could be wished for. The officers and men of the legion and militia performed everything that could be expected; and Major Maham of my brigade, had, in a particular manner, a great share of this success by his unwearied diligence in erecting the tower which principally occasioned the reduction of the fort. In short, sir, I have had the greatest assistance from every one under my command. Enclosed is a list of the prisoners and stores taken, and I shall, without loss of time, proceed to demolish the fort; after which I shall march to the high hills of Santee, encamp at Capt. Richardson's, and await your orders.
(Signed) Francis Marion.
In taking post at the Santee Hills, the object of Marion was to take such a position as would enable him to watch all the several roads by which Watson could make his way to Camden. It was important, if possible, to prevent his junction with Lord Rawdon, thus increasing the ability of that commander to cope with Greene's army, which now lay before that place. But Marion was not able to encounter Watson without assistance. Lee, with his legion, had been withdrawn by Greene soon after the capture of Fort Watson, and our partisan's force in camp, from concurring circumstances, was now reduced to about eighty men. Eighty of his brigade were detached under Col. Irvine to Rafting Creek, in order to cut off supplies from Camden. Another party was engaged in watching a rising of the Tories on the Pedee, who, in the absence of Marion himself, had manifested a disposition to resume the offensive; Col. Harden, with another detachment, was on the Salkehatchie, having first succeeded in the capture of Fort Balfour at Pocotaligo, in which he made nearly a hundred prisoners. Other small detachments had thinned the little army of our partisan to such a degree that it was of small efficiency where it was; and, just at this juncture, numerous desertions took place from two concurring circumstances. The approach of Marion to the hills had brought on the battle of Camden. Unwilling that Greene's force should be increased by the militia of the former, Rawdon had resolved not to wait for Watson, but to march out and give battle before the coming of either. He did so. The affair was not decisive, but Greene was compelled to yield the field to his enemy. He lost nothing, whether of honor or position, by this result. But, as the news spread, the defeat was exaggerated. It was supposed to be another affair such as that of Gates, and Marion's small body of men was still farther lessened by desertion. There was still another reason for its present feebleness. The time of the year was the very height of the planting season, and the farmer-soldiers, in numbers, left the camp in order to hurry to their homes and set their crops. This, though not allowed by the regular disciplinarian, was, in the mind of the militia-man, a duty quite as imperative as any that he owed to his family. Indeed, it was inseparable from his necessities that, where the Government did not give him bread, he must make it for himself. His family could not starve, and if he could fight without pay, it was not possible that he should do so without food. In the sort of warfare which Marion had hitherto carried on, he had been willing to recognize these necessities on the part of his followers. Cooperating with an army differently constituted, it was scarcely possible to do so, with any hope of their permanent usefulness. Just at this juncture, in particular, he felt the peculiarly mortifying character of his situation.
To enable Marion to contend with Watson, Greene dispatched Major Eaton, with a body of Continentals, to his assistance, with instructions to throw himself across the path of Watson. But Eaton, by an unhappy misunderstanding of his duty, failed to reach him in season for this object. When he did join him, which was on the evening of the 2d of May, it was too late. Marion, writing to Greene, says, "Major Eaton's not coming up sooner has made me lose a great deal of precious time. I shall cross the Santee at Wright's Bluff to-morrow." He did so, but Watson had already passed, and succeeded in eluding Greene also, and in reaching Camden in safety.
We have spoken of Col. Harden's proceedings against Fort Balfour, and the capture of that post. This officer was a very brave and active gentleman, rapid in his movements, and resolute in his objects. As soon as Marion had received intelligence of Greene's approach to South Carolina, he had dispatched Harden with seventy select men, well mounted, to penetrate through the country, and crossing the enemy's lines of communication, to stir up the people in all that region which lies southwest of Charleston. So rapid and unexpected were his movements, that he took the enemy everywhere by surprise, and rendered himself, for the time, the very terror of the loyalists upon the route. His force increased with its progress. The inhabitants yearned for an escape from British authority, and joined his troop. His seventy men soon became two hundred, and while he baffled the pursuit of the superior, he visited with sudden and severe chastisement the disaffected, along and on both sides of the Savannah river. Ascending this, he soon communicated with Pickens, then operating against Augusta and Ninety-Six. Nothing now was wanting but the fall of the enemy's chain of posts, to complete the recovery of the whole country within thirty miles of the sea. In contributing to this desirable object Marion, now strengthened by the Continentals of Lee and Eaton, invested Fort Motte on the river Congaree.
This post was the principal depot of the convoys from Charleston to Camden, and sometimes of those destined for Forts Granby and Ninety-Six. A large new mansion-house belonging to Mrs. Motte, situated on a high and commanding hill, had been chosen for this establishment. It was surrounded with a deep trench, along the inner margin of which a strong and lofty parapet was raised. To this post had been assigned a sufficient garrison of one hundred and fifty men. This force was increased by a small detachment of dragoons from Charleston, which had been thrown into it a few hours before the appearance of the Americans. The garrison was commanded by Capt. McPherson, a firm and gallant officer.
Opposite to Fort Motte, to the north, stood another hill, where Mrs. Motte, who had been expelled from her dwelling, resided in an old farm-house. On this, Lee took position with his corps: Marion's men occupied the eastern declivity of the same ridge on which stood the fort.
