The Monocacy (10 guns) and Palos (4 guns) steamed up the Salée River and disembarked a landing party of 546 sailors and 105 marines, taking with them a battery of seven boat-guns. Five forts were to be captured, situated at distances of from half a mile to three miles. The Monocacy, taking position abreast the first fort, shelled it vigorously, protecting the landing party and driving the Coreans from the earthworks and stone fort in about one hour. The landing party entered without resistance, capturing and destroying two 32-pdrs., six 18-pdrs., and twenty smaller pieces, 2 and 4 pdrs. The advance stopped for the night, the landing party going into camp outside of the fort. At daylight of the 11th the advance recommenced, the Monocacy keeping abreast and shelling the Coreans out of the second fort, which was occupied and dismantled. The citadel about three miles farther up the river was the next point to be captured, and had to be taken by assault. Marching to the crest of a hill within 150 yards of the citadel, the storming party were ordered to lie down for a rest, the skirmishing line of marines keeping up a fire on the parapet. A detachment of men and guns was sent to occupy a commanding position and hold a large body of Coreans in check that was forming in rear, while another detachment was sent to cut off the retreat from the citadel. A deep ravine lay between the storming line and the fort, and the walls of the citadel were twelve feet high, the only entrance being through a small breach made by the fire of the Monocacy. The citadel was stormed, and a foothold gained without a halt, and after a hard hand-to-hand fight, was captured. With the fall of the citadel the other forts were abandoned, whilst the detachment commanding the road of retreat of the Coreans put them under a severe fire. The assault was a complete success. Loss of the Coreans: killed, 243; wounded, unknown; prisoners, 22; five stone forts and 481 pieces of ordnance, comprising eleven 32-pdrs., fourteen 24-pdrs., two 20-pdrs., and the remainder 2 and 4 pdrs.; fifty flags, including the standard of the Generalissimo. Loss of United States: killed, 3; wounded, 10. RÉSUMÉ. Number of assaults noted, 3. Failures, 2. Success, 1. Of the failures, the first was too hastily planned to even make a commencement. Everything was confusion from the time that the boats were cast off from their tows. The second was primarily due to confusion of the assaulting columns at the most critical moment, followed by a panic.
