The detachments ordered against the posts in the north-eastern parts of the state, under the command of Sumpter, were not so completely successful as their numbers, courage, and enterprise deserved. The several corps took distinct routes, intending to fall on the different posts between Ashley and Cooper rivers, at the same time. That at Dorchester was broken up, on the approach of Lee, who captured horses, military stores, and baggage to a considerable amount, and obtained some trivial successes over the flying enemy. Lieutenant Colonel Wade Hampton, of the state cavalry, fell in with a body of mounted refugees, dispersed the whole, and made forty or fifty prisoners. Sumpter advanced against Monk's corner. This post was defended by Lieutenant Colonel Coates with the 19th British regiment, and a troop of horse. He had taken possession of a brick church at a bridge over Biggin creek, the most northern of the water courses which form the west branch of Cooper river. After passing Biggin, the road to Charleston crosses first Wattoo, and then Quinby creek; neither of which is passable except at the bridges over which the road leads, and at a ferry over Quinby. On the sixteenth, Sumpter approached Monk's corner, but, not supposing himself strong enough to hazard an attack until all his detachments should be collected, sent a party to seize the bridge over Wattoo, and either to hold or to destroy it. This party being attacked by a superior force, retired from the bridge without completing its destruction, and without informing Sumpter that his orders had not been fully executed. Marion had joined Sumpter. Lee arrived late in the evening, and the resolution was taken to attack Coates early next morning. In the course of the night he set fire to the church, in order to destroy the stores which were collected in it, and commenced his march to Charleston, by the road east of Cooper. Having repaired the bridge over Wattoo, he met with no obstruction; and proceeded with his infantry on the road leading to Quinby bridge, directed his cavalry to take a road turning to the right, and crossing the creek at the ferry. About three next morning, the flames bursting through the roof of the church announced the retreat of the British; and the pursuit was immediately commenced. Sumpter was preceded by the legion, supported by the state cavalry. A detachment from this regiment followed the British horse, in the vain hope of overtaking the troop at the ferry, while Lee pursued the infantry. Within a short distance of the bridge, which is eighteen miles from Monk's corner, he perceived the rear guard of the British, consisting of about one hundred men, commanded by Captain Campbell, which the cavalry charged, sword in hand. They threw down their arms, and begged for quarter; upon which they were placed under the care of a few militia horsemen, and the American cavalry resumed the pursuit.
