On 18 April 1800 a court martial was held on board GLADIATOR in Portsmouth on John Briscoe, a marine belonging to DIADEM. He was found guilty of writing a letter to Gen. Averne, and causing others to sign it, calculated to cause a disturbance in the ship. He was sentenced to receive 200 lashes from ship to ship and to spend 6 months in the Marshalsea.

- 1805 Capt. Sir Home POPHAM.
On a secret expedition, which turned out to be an attack on the Cape of Good Hope. On the way out the fleet of ships-of-war, transports and Indiamen under convoy, made one stop at Madeira for water. NARCISSUS was sent on ahead to obtain intelligence and capture or destroy any vessels which might give the Dutch notice of the approach of the fleet.
The fleet anchored to the westward of Robben Is. on 4 January 1806 and LEDA and the transports containing the 24th. regiment demonstrated off Green Point. On the 5th. the troops were put in the boats and assembled alongside ESPOIR but the surf was so high that they were put back in their ships.
Capt. POPHAM joined Gen. Baird on ESPOIR to examine the coast but when DIOMEDE, with the transports of the 38th. regiment, cavalry, and some of the artillery, reported that a landing was possible in Saldanha Bay, the army was landed there, covered by DIADEM, LEDA and ENCOUNTER. Only one boat was lost with 35 the 93rd. Highland regiment. The efforts to save them were defeated by the long and thick seaweed which rendered the boat's oars useless.
A number of officers from the naval ships, transports and East Indiamen joined the troops ashore. The Dutch Gen. Jansens had 5,000 troops which included Hottentot riflemen but was defeated by Gen. Baird with the loss of only 15 British soldiers killed.
At 9 o'clock on the morning of 4 March three ships, one a French warship, were reported coming from the southward towards Table Bay where DIADAM was lying under Dutch colours. Capt. POPHAM ordered DIOMEDE and LEDA to slip and then realised that the two ships in the offing were RAISONABLE and NARCISSUS. The French ship passed within hail of DIADEM which lowered the Dutch colours, hoisted British and called on her to strike. She did immediately and Capt. PERCY, a volunteer, took possession. She was the VOLONTAIRE (48), from Brest, with 270 prisoners on board, 217 men of the Queen's and 54th. regiment which had been taken in two transports in the Bay of Biscay.
Capt. POPHAM appointed Capt. Josceline PERCY to command the prize. She was manned by as many sailors as could be spared from the squadron and sent to St. Helena to act as escort for the homeward bound Indiamen.
At St. Helena Capt. BUTTERFIELD, in charge of the transports manned VOLUNTAIRE from the crews under his command, replacing them with Dutch prisoners.
Capt. PERCY had come out to take command of ESPOIR but she had sailed for England with dispatches and he had been sent to take command of the BATO, a Dutch 68, in Simon's Bay but she was found to be a complete wreck.
- Capt. POPHAM's squadron captured, retook or destroyed 11 vessels between 4 October 1805 and 30 March 1806.
- Sir Home POPHAM finding himself with a squadron and a small army, persuaded Gen. Baird to join him in crossing the South Atlantic to attack Buenos Aires. He appointed Lieut. William KING, who had been first lieutenant of DIADEM and then commanded ESPOIR during the expedition against the Cape, to act as captain of DIADEM.
(These were unauthorised promotions and were not ratified by the Admiralty.)
- They were reinforced at St. Helena by troops under Major Gen. Beresford and reached Monte Video on 16 June 1806. 1,700 men were landed on the 25th. at Point Quelmey a Pouchin about 12 miles from Buenos Aires covered by ENCOUNTER which ran close in shore.
They included the marines of the squadron, augmented by seamen, plus three companies of 'Royal Blues' from the same source, under the command of Capt. KING.
(The Royal Blues were 'grenadiers' selected from among the ship's companies and equipped as artillery men. They were constantly drilled by the army officers on board the ships.
Other volunteer seamen were attached to the marines, dressed and accoutred like them.)
The heavy artillery had to be dragged by the navy through several miles of swamps but the British force pushed back 2,000 Spaniards with a bayonet charge, and took possession of Buenos Aires on the 27 June.
1,000,000 dollars in the public treasury were sent to England.
Meanwhile Sir Home POPHAM sailed to attempt an attack on Monte Video with DIADEM, DIOMEDE and RAISONABLE.
- On 30 July, when DIADEM was anchored off Monte Video, a strange sail was seen. Capt. KING weighed and gave chase until DIADEM was in 4 fathoms of water, when he hove to and sent off the boats which soon captured her. She was the Spanish man-of-war brig ARROGANTE, pierced for 12 guns but with only 2 mounted.
After three weeks the Spaniards in Buenos Aires realised how small the British force was and rose against them.
Sir Home ordered DIOMEDE to go up to to Ensenada and for Capt. KING to bring the remaining marines of DIADEM and seamen from the ships to join her for an attack on the Spaniards at Colonia.
On 1 August he went across the river in LEDA and anchored about 12 miles off Buenos Aries. He landed the next day to consult with Gen. Beresford and attempted to return to LEDA in ENCOUNTER but the wind was too strong.
On the 5th. Capt. KING managed to get through the gale with 150 men from DIADEM to man the small vessels they had found in the harbour but on the 6th. and 7th. it blew a hurricane and five of the gunboats foundered at anchor. The launches and large cutters of DIADEM and LEDA were also lost. The enemy managed to cross the river under cover of the bad weather and eventually Beresford was surrounded and forced to surrender on the 12 August.
- On 3 October DIADEM fell in with ROLLO which had brought a detachment of the 38th. from the Cape. Sir Home took the troops out of her and sent her up to Rio Grande in southern Brazil to obtain bread or biscuit.
On the 6th. he joined PROTECTOR with the ADAMANT and COLUMBINE transports and ordered them to load provisions for 3 months from the DIADEM victualler in case any accident happened to her. The following day MEDUSA, LEDA and two of LANCASTER's convoy joined. The weather was hazy and the current so strong that LANCASTER and the two remaining ships did not arrive until the 12th.
The next day Col. Backhouse proposed a look at Monte Video prior to attacking the place but from the 15th. to the 27th. it blew so hard that nothing could be attempted.
On the 28th. they had a go a breaching the walls for the army but could not get close enough, so Sir home POPHAM proposed taking Maldonada instead.
The troops from DIADEM assembled alongside LEDA and a landing was effected without opposition. On the morning of the 30th. Lieut. WISEMAN of DIADEM accepted the surrender of the fortified island of Gorretti which formed the harbour.
- When news of his exploits reached London, the Admiralty recalled Sir Home POPHAM and Capt. Samuel WARREN, accompanied Rear Ad. STIRLING to the River Plate as a passenger in the SAMPSON (64), to take over command of DIADEM as the Rear Admiral's flagship at Maldonada.
Sir Home POPHAM was severely reprimanded by a court martial for abandoning his post at the Cape without orders.
More troops were sent out under Brigadier Gen. Sir Samuel Auchmuty and, after assembling off the Island of Flores, a landing was made at Carreta Point, 7 miles to the eastward of Monte Video on 16 January 1807. About 800 seamen and marines were landed under Capt. DONNELLY and guns from the men-of-war were taken ashore. Since the shallow water prevented the ships from approaching within shooting range, Rear Ad. STIRLING disposed his squadron to prevent any escape from the harbour. Almost 1,400 men from the squadron were ashore every day and often DIADEM had only 30 men on board.
- When only 2 days supply of powder remained in the King's ships, the transports and the merchantmen when a breach was made on 3 February and the town and citadel were carried by storm. Two seamen from DIADEM, Ralph BLAIR and John FRANCIS, were killed in the attack and one, Thornton PURKE was badly wounded. Marine John Craig was slightly wounded.
One 28-gun frigate was set afire by her crew in the harbour and blew up with an enormous explosion. A large number of vessels, some old and useless, some well found, were taken.
- 1808 Out of commission at Sheerness.
- 1810 armed en flute again as a troopship.
Capt. John PHILLIMORE, 06/1810, Lisbon.
In the autumn to Leith.
- 1812 coast of Spain.
He removed to EUROTAS on 4 May 1813.
- 1813 Capt. John M. HANCHETT, Halifax.
On 22 June 1813 an attack was launched on Craney Island (now a US
Navy Base) at Portsmouth, Virginia. The island covered a narrow channel leading to Norfolk which would enable light vessels to transport troops to attack the frigate CONSTELLATION.
Ad. WARREN directed that the troops under Sir Sydney Beckwith should be supported by marines and seamen from the ships but after discovering that the island was too well fortified he ordered that the troops should be re-embarked. Capt. HANCHETT, who volunteered to lead the division of boats was severely wounded by a ball in the thigh.
- On September 1814 DIADEM took part in Vice Ad. COCHRANE's expedition against Baltimore. It was planned as a demonstration which could be converted into a real attack if circumstances allowed. The fleet, which included TONNANT, ALBION, RAMILLIES, DIADAM, MELPOMENE, TRAVE, MADAGASCAR and ROYAL OAK, proceeded up the Chesapeake and anchored off the mouth of the Patapsco on the 11th. The frigates and smaller vessels went in and early next morning the army, under Major Gen. Ross, was landed without opposition. It was accompanied by 600 seamen under Capt. Edward CROFTON, the 2nd battalion of marines, the marines of the squadron and the colonial black marines.
Rear Ad. COCKBURN acted as naval adviser.
While reconnoitring the enemy before daybreak Gen. Ross was mortally wounded by a musket ball and command devolved on Col. Brooke.
He advanced to within 5 miles of Baltimore and scattered a force of some 6 or 7,000 enemy which fled the field leaving a number of killed and wounded and two pieces of cannon.
The following morning the bombs, frigates and sloops opened fire on the forts protecting the harbour, but when the Vice Admiral inspected the seaward defences he concluded that the navy would be unable to support an attack by the army. It was therefore decided that the army would retire.
Lieut. Samuel MARSHALL of DIADEM, who was with the Naval Brigade, was severely wounded, James CONNER, ordinary seaman, was badly wounded and John MOORE, able seaman was slightly wounded.
