In 1796, having been promoted to lieutenant and still in Egmont, Jackson was integral in the saving of the entire crew of the ship of the line HMS Bombay Castle off the Tagus during a large storm.

Despite being vastly outnumbered by the captives on board, Jackson distinguished himself by successfully subduing an attempted take over and bringing the ship safely to Gibraltar.

He fought a number of engagements against the ships and fortifications of Calais and Boulogne in this period, and also in 1805 saved a large troop convoy under his control from destruction off the Texel.

He served for a while in the English Channel and Mediterranean before going to the Baltic Sea where, again under the command of Richard Goodwin Keats,he participated in the evacuation of La Romana's division in 1808.

Superb was decommissioned after this and Jackson stayed unemployed until 1812 when he was made temporary captain of the ship of the line HMS Poictiers, in which he served in the English Channel and North Sea Fleet.

After returning home in 1815 Jackson was given command of another frigate, HMS Niger, and sent back to North America where he became senior naval officer on the coast of Nova Scotia.

[1][2] From here Romulus joined with the frigate HMS Meleager to hunt down a group of privateers loyal to the French cause and known to operate off Capraja.

[5] Romulus and Jackson stayed in the Mediterranean Sea after these actions, participating in a prolonged attack on the forts of Bastia with the ship of the line HMS Agamemnon.

On 9 March, Jackson participated in a boat action wherein the force captured the French warships Nemesis and Sardine, as well as a polacre, and destroyed a cutter.

[1][6] Soon after this Jackson left the service of Sutton and joined the ship of the line HMS Victory, the flagship of the new commander of the Mediterranean Fleet, Admiral Sir John Jervis.

Jackson then volunteered to and successfully traversed the increasingly bad sea conditions to bring a letter to Jervis explaining the perilous position of Bombay Castle's crew.

Jervis gave Jackson the responsibility of navigating all the remaining boats of the fleet back to the stranded ship to remove her crew to safety.

[1][12][13] In June 1799 Superb was sent as part of a detached squadron to join the force of Rear-Admiral Sir Charles Cotton in chasing the escaped fleet of Étienne Eustache Bruix from Brest to the Mediterranean.

[12][13] Keats having returned to command Superb, they were watching the entrance to the River Guadilquivir, somewhat detached from the main British force, under Rear-Admiral Sir James Saumarez which went in search of a French squadron thought to be exiting the Mediterranean.

When on 12 July the combined French and Spanish squadron made to leave the bay to escape to Cadiz, Saumarez, although outnumbered two to one went in chase, which led to the Second Battle of Algeciras.

With lights concealed and making no signals she ranged alongside a Spanish three decker (the Real Carlos) and discharged three broadsides before being met by return of fire.

[16] In the subsequent fleet action Superb continued fighting and engaged the French ship of the line San Antoine for half an hour before accepting her surrender.

[22] While it was surmised that much damage was done in the operation, Jackson felt that more could be done with better preparation and his comments resulted in bombardments of the coastal towns being suspended until a larger force could be provided for the task.

[23] Towards the beginning of 1804 some of the ships left in Calais sailed for Boulogne, staying close to the French coast so as to gain the added protection of the shore batteries there.

Owen's squadron was situated twenty-four miles off Boulogne at the time and managed to intercept a number of the ships as they moved away from the cover of the French coast.

While the darkness and sea conditions made it impossible to gauge how many French ships had escaped, been destroyed by the British or been blown ashore independently by the storm, it was seen as a great success and Jackson was praised for his part in the attack.

Jackson left Autumn in October, and was immediately appointed to a new command, that of the brig HMS Musquito, to serve on the North Sea Station.

As 1805 came to an end Jackson still commanded Musquito, and was given control of a convoy of troopships containing 5,000 soldiers and a large amount of ammunition and provisions, intended for the Hanover Expedition.

[32] After this, and into 1806, Jackson was given command of a group of ships stationed off Boulogne and Calais, again tasked with stopping the transit of small and lightly armed warships along the coast.

[27][32] When Copenhagen surrendered and gave up the navy to the British, Jackson was given temporary command of the frigate HMS Surveillante when in turn her captain was sent home with the Expedition's celebratory dispatches.

Having been unable to catch that force, Superb and Jackson returned to England from where he was assigned to the Baltic Sea squadron of the now Rear-Admiral Keats as his flag captain.

[35] He was able to return to duty in January 1809 after a canal was cut through four miles of ice for his ship to travel through, but by this point the heavy service of Superb had left her in a poor condition to continue serving.

Jackson stayed ashore, unemployed by the navy, until 14 January 1812 when he was appointed to temporarily command the ship of the line HMS Poictiers in the English Channel.

[39][40] He continued on station, and shortly after 15 January 1815 Jackson sailed up the Chesapeake River and successfully recaptured an East India Company ship, that had recently been taken, finding no resistance from American forces as he did so.

[1] While serving in command of Bellerophon in the Mediterranean, Jackson met soldier, antiquarian and scholar Thomas Reade who was at the time the British consul general in Tunis.
