The Sphinx-class sailing sixth rates were a series of ten post ships built to a 1773 design by John Williams. Although smaller than true frigates, post ships were often referred to incorrectly as frigates by sea officers, but not by the Admiralty or Navy Board.

Post ship was a designation used in the Royal Navy during the second half of the 18th century and the Napoleonic Wars to describe a ship of the sixth rate that was smaller than a frigate, but by virtue of being a rated ship, had to have as its captain a post captain rather than a lieutenant or commander. Thus ships with 20 to 26 guns were post ships, though this situation changed after 1817.

The first vessel in the class was launched in 1775, six more in 1776, two in 1777 and the last in 1781. The vessels of the class served in the Royal Navy during the American Revolutionary War. Three of them - Sphinx and Ariel in September 1779, and Unicorn in September 1780 - were captured by the French Navy, but Sphinx was recovered in December 1779 and Unicorn in April 1781. Some survived to see service in the French Revolutionary and Napoleonic Wars.

The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the Kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service.

American Revolutionary War 1775–1783 war between Great Britain and the Thirteen Colonies, which won independence as the United States of America

The American Revolutionary War (1775–1783), also known as the American War of Independence, was an 18th-century war between Great Britain and its Thirteen Colonies which declared independence as the United States of America.

French Revolutionary Wars series of conflicts fought between the French Republic and several European monarchies from 1792 to 1802

The French Revolutionary Wars were a series of sweeping military conflicts lasting from 1792 until 1802 and resulting from the French Revolution. They pitted the French Republic against Great Britain, Austria and several other monarchies. They are divided in two periods: the War of the First Coalition (1792–97) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered a wide array of territories, from the Italian Peninsula and the Low Countries in Europe to the Louisiana Territory in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe.

A frigate is a type of warship, having various sizes and roles over the last few centuries.

USS <i>Confederacy</i> (1778)

Sloop-of-war ship type

In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialized functions.

Continental Navy

The Continental Navy was the navy of the United States during the American Revolutionary War, and was formed in 1775. The fleet cumulatively became relatively substantial through the efforts of the Continental Navy's patron John Adams and vigorous Congressional support in the face of stiff opposition, when considering the limitations imposed upon the Patriot supply pool.

Admiral Thomas Mackenzie was a prominent British Royal Navy officer of the late eighteenth century. Mackenzie's career, while successful, was blighted by a series of controversies that limited his opportunities and command, resulting in his placement in reserve for the last 19 years of his career. During his early service, Mackenzie served at a number of engagements in the American Revolutionary War and advanced rapidly, but he was caught during service in the Indian Ocean in the midst of a disagreement between two senior officers and as a result was placed in reserve at the end of the war. At the start of the French Revolutionary Wars ten years later Mackenzie was restored to service, and commanded the ship of the line Gibraltar at the Glorious First of June. Mackenzie was again involved in a major dispute in the aftermath of the battle over credit for the victory, with the result that he never again served at sea.
