Context paragraphs:
The Sailor's Daughter: The Sailor's Daughter is a comedy play by the British writer Richard Cumberland which first premiered on 7 April 1804.  After a young woman, Julia, is orphaned following the Battle of Copenhagen she enjoys a series of adventures until settling down with her long-lost guardian Captain Sentamore.

Battle of Sadras: The Battle of Sadras was the first of five largely indecisive naval battles fought between a British fleet (under Admiral Sir Edward Hughes) and a French fleet (under the Bailli de Suffren) off the east coast of India during the Anglo-French War.  Fought on 17 February 1782 near present-day Kalpakkam, the battle was tactically indecisive, but the British fleet suffered the most damage.  Under Suffren's protection, French troop transports were able to land at Porto Novo.

Battle of Quiberon Bay: The Battle of Quiberon Bay (known as Bataille des Cardinaux in French), was a decisive naval engagement fought on 20 November 1759 during the Seven Years' War between the Royal Navy and the French Navy.  It was fought in Quiberon Bay, off the coast of France near St. Nazaire.  The battle was the culmination of British efforts to eliminate French naval superiority, which could have given the French the ability to carry out their planned invasion of Great Britain.  A British fleet of 24 ships of the line under Sir Edward Hawke tracked down and engaged a French fleet of 21 ships of the line under Marshal de Conflans.  After hard fighting, the British fleet sank or ran aground six ships, captured one and scattered the rest, giving the Royal Navy one of its greatest victories, and ending the threat of French invasion for good.

Order of battle at the Battle of the Nile: The Battle of the Nile was a significant naval action fought during 1–3 August 1798.  The battle took place in Aboukir Bay, near the mouth of the River Nile on the Mediterranean coast of Egypt and pitted a British fleet of the Royal Navy against a fleet of the French Navy.  The battle was the climax of a three-month campaign in the Mediterranean during which a huge French convoy under General Napoleon Bonaparte had sailed from Toulon to Alexandria via Malta.  Despite close pursuit by a British fleet of thirteen ships of the line, one fourth rate and a sloop under Sir Horatio Nelson, the French were able to reach Alexandria unscathed and successfully land an army, which Bonaparte led inland.  The fleet that had escorted the convoy, consisting of thirteen ships of the line, four frigates and a number of smaller vessels under Vice-Admiral François-Paul Brueys D'Aigalliers, anchored in Aboukir Bay as Alexandria harbour was too narrow, forming a line of battle that was protected by shoals to the north and west.

Action of 18 August 1798: The Action of 18 August 1798 was a minor naval engagement of the French Revolutionary Wars, fought between the British fourth rate ship HMS "Leander" and the French ship of the line "Généreux".  Both ships had been engaged at the Battle of the Nile three weeks earlier, in which a British fleet under Rear-Admiral Sir Horatio Nelson had destroyed a French fleet at Aboukir Bay on the Mediterranean coast of Egypt.  "Généreux" was one of only four French ships to survive the battle, while "Leander" had been detached from the British fleet by Nelson on 6 August.  On board, Captain Edward Berry sailed as a passenger, charged with carrying despatches to the squadron under Earl St Vincent off Cadiz.  On 18 August, while passing the western shore of Crete, "Leander" was intercepted and attacked by "Généreux", which had separated from the rest of the French survivors the day before.

Battle of Groix: The Battle of Groix was a large naval engagement which took place near the island of Groix off the Biscay coast of Brittany on 23 June 1795 (5 messidor an III) during the French Revolutionary Wars.  The battle was fought between elements of the British Channel Fleet and the French Atlantic Fleet, which were cruising in the region on separate missions.  The British fleet, commanded by Admiral Lord Bridport, was covering an invasion convoy carrying a French Royalist army to invade Quiberon, while the French under Vice-amiral Villaret de Joyeuse had sailed a week earlier to rescue a French convoy from attack by a British squadron.  The French fleet had driven off the British squadron in a battle on 17 June known as Cornwallis's Retreat, and were attempting to return to their base at Brest when Bridport's force of 14 ships of the line appeared on 22 June.

Seal of South Carolina: The Great Seal of the State of South Carolina was adopted in 1776.  The seal is made up of two elliptical areas, linked by branches of the palmetto tree.  The image on the left is dominated by a tall palmetto tree and an oak tree, fallen and broken.  This scene represents the battle fought on June 28, 1776, between defenders of the unfinished fort on Sullivan's Island, and the British Fleet.  The standing palmetto represents the victorious defenders, and the fallen oak is the British Fleet.  Banded together on the palmetto with the motto "Quis separabit? " ("Who Will Separate [Us]?") , are 12 spears that represent the first 12 states of the Union.  Surrounding the image, at the top, is "South Carolina", and below, is "Animis Opibusque Parati" ("Prepared in Mind and Resources").  The other image on the seal depicts the Roman Goddess Spes walking along a shore that is littered with weapons.  The Goddess, symbolizing Hope, grasps a branch of laurel as the sun rises behind her.  Below her image is her name "Spes", Latin for "Hope", and over the image is the motto "Dum Spiro Spero", or "While I Breathe I Hope".

Capture of St. Lucia: The Capture of St Lucia was the result of a campaign by British land and naval forces to capture the island of St Lucia, which was a French Colony.  Britain's actions followed the capture of the British controlled island of Dominica by French forces after a surprise invasion in September 1778.  During the Battle of St. Lucia the British fleet defeated a French fleet sent to reinforced the island, and a few days later French troops were soundly defeated by British troops during the Battle of Morne de la Vierge.  Realising that another British fleet would arrive shortly with reinforcements, the French garrison surrendered.  The remaining French troops were evacuated and the French fleet returned to Martinique, leaving the island in the hands of the British.

Order of battle at the Battle of Camperdown: The Battle of Camperdown was an important naval action of the French Revolutionary Wars, fought off Camperduin on the North Holland coast on 11 October 1797 between a British fleet under Admiral Adam Duncan and a Dutch fleet under Vice-Admiral Jan de Winter.  The French Republic had overrun the Dutch Republic two years earlier, reforming it into the Batavian Republic.  In early 1797, the Dutch Navy was ordered to sail to Brest and unite with the French Atlantic Fleet in preparation for an invasion of Ireland.  Shortly afterwards, the British fleets were paralysed by the Spithead and Nore mutinies, in which the sailors refused to take their ships to sea until they were awarded better pay and conditions.  For two months, the English Channel was undefended, but the Dutch failed to take the opportunity to sail from their harbour in the Texel: their preparations were not complete, and a small squadron of loyal British ships under Duncan convinced de Winter that the British fleet was at sea by sending nonsensical signals to fictitious ships over the horizon.

Battle of Copenhagen (1801): The Battle of Copenhagen 1801 (Danish: "Slaget på Reden" ) was the first of two battles which saw the British fleet under the command of Admiral Sir Hyde Parker and Horatio Nelson, a vice admiral in 1801, fight a huge Danish fleet anchored just off Copenhagen on 2 April 1801.  The Danish fleet at the inlet of the Copenhagen harbour formed a blockade preventing the British fleet from entering the harbour.  The Danish mainly used older ships not meant to sail in the sea as blockades.  Denmark defended the capital with these ships and bastions on both side of the harbour inlet, "Kastellet", "Trekroner", "Lynetten" (which all still exists) as well as "Quintus", "Sixtus" and "Strickers".  It was the second attempt by the British to scare Denmark, as the British had already entered Øresund with a navy in August 1800, in order to force Denmark to sign an alliance with Britain.  Now Britain would have Denmark's entire navy and merchant fleet, so it would not fall into the hands of the French.  The British were not aware that the modern Royal Danish Navy and many merchant ships were well hidden in the Roskilde fjord, a bluff which was never called by the British.
