A gun-brig.

This was a small brig-rigged warship that enjoyed popularity in the (British) Royal Navy during the Napoleonic Wars, during which large numbers were purchased or built. In general these were vessels of under 200 tons burthen, and thus smaller than the more common Cherokee-class brig-sloops or the even larger Cruizer-class brig-sloops. The gun-brigs generally carried 12 guns, comprising two long guns in the chase position and ten carronades on the broadsides.

Development.

The earliest gun-brigs were shallow-draught vessels. Initially they were not brigs at all, but were classed as 'gunvessels' and carried a schooner or brigantine rig. They were re-rigged as brigs about 1796 and re-classed under the new term 'gun-brig'. They were designed as much to row as to sail, and carried their primary armament firing forward - a pair of long 18-pounders or 24-pounders, weapons which in any practical sense could only be trained and fired with the vessel under oars.

The 1797 batch introduced means to improve their sailing ability. Each was fitted with a Schank drop keel, and lighter bow chasers replaced the heavy pair of guns firing forward over the bows; in later vessels one of the bow chasers would be moved aft to become a stern chaser, both of these guns then being mounted on the centreline and able to pivot. The broadside weapons consisted of 18-pounder carronades mounted on slides along both sides.

The later gun-brigs developed from this beginning into smaller versions of the brig-sloops with increased draught and seaworthiness, but were less suited for inshore warfare. Compared with the flat-bottomed hulls of the 1794-1800 designs, by the time of the Confounder class the hulls had achieved a relatively sharp cross-section, as performance under sail had become a more important consideration than ease of rowing. By now they were clearly seen as small versions of the brig-sloop rather than enlarged gunboats.

Deployment.

The early gun-brigs were seen as inshore and coastal vessels, and saw their first service in coastal operations, notably in the Channel, where they sought out French coastal shipping. As their numbers grew and more seaworthy designs emerged, they were deployed worldwide, notably in the Baltic where many were involved in confrontations with the myriad of Danish gunboats during the Gunboat War, but also on such distant stations as the East Indies.

Complement.

The purpose-built gun-brigs were all established with a complement of 50 men, and maintained this level throughout their main period of operation, although the actual number carried varied with availability. The final batch saw the complement raised to 60. Each gun-brig had a lieutenant in command (unlike brig-sloops, which were under commanders), and while he was the only commissioned officer aboard, he was assisted by a midshipman and a number of warrant officers - a master's mate (ranked as 'master and pilot') to share the watches, carpenter's mate, gunner's mate, boatswain's mate and surgeon's mate. Other petty officers included a ropemaker, sailmaker, clerk, quartermaster and quartermaster's mate. There were fifteen marines on board - a sergeant to command, a corporal, and thirteen privates. The rest of the crew were ranked as seamen - able seamen, ordinary seamen or landsmen.
