The following night, O'Bryen was ordered to assist Brigadier-General Hughes in the taking of Braam's Point. A sandbar initially prevented "Emerald" from entering the Surinam River but O'Bryen forced her across on the rising tide, with "Pandour" and "Drake" following. Anchoring close by, the three British ships quickly put the Dutch battery of 18-pounders out of action and captured the fort without loss of life. "Emerald", "Pandour", and "Drake" then pushed up the river, sometimes in less water than the frigates required to float properly, until on 5May they arrived close to the forts Leyden and Frederici. The British landed a detachment of troops under Hughes some distance away, which marching under the cover of the forests and swamps, launched an attack that resulted in the swift capture of the two forts. By this time, most of the squadron had managed to work its way up the river as far as Frederici, Maitland was advancing along the Commewine River, and with troops poised to attack the fort of New Amsterdam, the Batavian commandant, Lieutenant-Colonel Batenburg, duly surrendered. "Emerald" captured the vessel "Augusta", which was under American colours, on 22 August and sent her into Antigua with the cargo of wine that she had been carrying from Leghorn to Guadeloupe. "Emerald" left Tortola on 26 October as escort to a convoy of 50 vessels for England but having parted from them in a storm, she put into Madeira in distress on 11 December. Between February and June 1806, "Emerald" underwent repairs at Deptford dockyard and was recommissioned under Captain John Armour; Frederick Lewis Maitland assumed command in the first quarter of 1807. While in the Basque Roads in April, "Emerald" captured the 14-gun privateer "Austerlitz", a brig from Nantes under the command of Captain Gatien Lafont. "Emerald", while escorting a Spanish polacca that she had taken, spotted and captured the privateer on 14 April after a ten-hour chase. "Austerlitz" had been out of port two days but had made no captures; the polacca was the Spanish ship "Prince of Asturias", which had sailed from La Guayra with a cargo of cocoa, bark and indigo. "Emerald" sent both prizes into Plymouth, where they arrived on 22 April.
